[tidal kiln]

just to make sure - you're currently trying this out on a CPX?

[upbeat plover]

yeah the circuit playground express

[tidal kiln]

ok. here's a boot.py i've used before:

# boot.py
# Use this to control file system state on power up and/or HW reset.
# If read only is set to False, then CP can write to the file system.
# If read only is set to True, then USB can write to the file system.
import storage
from adafruit_circuitplayground.express import cpx

# toward ear = False (CP can write to file system)
# toward note = True (USB can write to file system)
read_only = cpx.switch
print("Read Only = ", read_only)
storage.remount("/", read_only)

you use the CPX slide switch to set mode

[upbeat plover]

ok so have cpx lib on board

[idle owl]

Make sure you paste the right thing into boot.py. If you paste the code.py into boot.py you run the risk of CircuitPython never completing startup. Not that I would know.

[upbeat plover]

im still getting OSError 30

how do you get the boot.py to load?

i tried reset button, and unplugging it and waiting then plugging it back in

[tidal kiln]

boot.py is run automatically with every reset

[upbeat plover]

switch in both possitions

with open("/tmp.txt", "a") as fp:
... fp.write("hello, world!")
...

then gives me error

[tidal kiln]

do you see tmp.txt in the CIRCUITPY folder?

[upbeat plover]

it was not there so i made one and still nothing

[tidal kiln]

@upbeat plover what version of CP are you currently running?

actually. nvm.

post the contents of boot_out.txt

[upbeat plover]

okay

Adafruit CircuitPython 3.0.0-rc.0 on 2018-06-18; Adafruit CircuitPlayground Express with samd21g18
boot.py output:
Testing
is it working?

lol... i think i found issue, was using Atom, now using Mu gana go back and try with your boot.py

[tidal kiln]

also. update to release version of 3.0:
https://github.com/adafruit/circuitpython/releases/latest

you're using RC0

[upbeat plover]

[tidal kiln]

ok. that's similar to what i'm getting with 3.0 (see my note about updating CP firmware above)

[upbeat plover]

my lib versions

okay ill try with 2.2.0

[tidal kiln]

use 3.0

same with bundle

CP:
https://github.com/adafruit/circuitpython/releases/latest
bundle:
https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/latest

i'm going to cook up a different boot.py that doesn't use adafruit_circuitplayground

[upbeat plover]

alright im gana put the newer CP on there then storage.erase_filesystem() and put newer lib in there

[tidal kiln]

ok. that'll be good to get back to a clean slate.

then try this for boot.py:

import board
import digitalio
import storage

# For Gemma M0, Trinket M0, Metro M0/M4 Express, ItsyBitsy M0/M4 Express
#switch = digitalio.DigitalInOut(board.D2)
# switch = digitalio.DigitalInOut(board.D5)  # For Feather M0/M4 Express
switch = digitalio.DigitalInOut(board.D7)  # For Circuit Playground Express
switch.direction = digitalio.Direction.INPUT
switch.pull = digitalio.Pull.UP

# If the switch pin is connected to ground CircuitPython can write to the drive
read_only = switch.value
print("Read Only = ", read_only)
storage.remount("/", read_only)

[adafruit/circuitpython] New comment on issue #979: Add CircuitPython libraries to pypi

@tannewt
@kattni
Not sure if this will work as a reply. I had inquired about some drivers and when they would be available on Pypi. I am working on a project using Adafruit boards with a Raspberrypi. I was asked if I would like to help with the conversion. I said yes and was directed here. Would like to help.

Mark

[upbeat plover]

@tidal kiln working now, thank you for your patience

[tidal kiln]

yeah!

fwiw, i got that boot.py from here:
https://learn.adafruit.com/circuitpython-essentials/circuitpython-storage
and just tweaked it to add the print, so you would get some confirmation in boot_out.txt

[idle owl]

I didn't know you could add prints to boot.py

[tidal kiln]

and they show up in boot_out.txt
handy!

[idle owl]

Weirdly I just said "handy!" to someone else.

[tidal kiln]

keen!

[tulip sleet]

@crude fossil saw your several-hours old msg; are you still having trouble?

[prime flower]

@tulip sleet tab completion on the MCP for pin-mapping was def. the way to go

easy to use, esp. for when people are going to be doing differential reads (nice to see what pins are available per-IC)

[tulip sleet]

vg! yes, that's the idea. I do it all the time when I can't remember something (or am just a lazy typist)

[prime flower]

It'll be neat when it's implemented on the crickit

like CRICKIT.MOTOR_PIN# or however it's implemented

[tulip sleet]

    crickit.continuous_servo_1.throttle = -1 # Forwards

OSError: [Errno 5] Input/output error

[solar whale]

@pallid cliff That code works on mine.

[pallid cliff]

huh

It consistently does one cycle, then throws the errors and just runs half foward endlessly

[solar whale]

at least the servo turns -- not quite sure the speeds are as expected -- first time I've tried a CR servo.

no erros for me - but it does not got to full stop

[pallid cliff]

yeah, just noticed that too. doesn't pause. It is still a fairly new library though, think it's worth opening an issue?

[solar whale]

I have not looked at it at all -- not sure what to expect. Open an issue if you thing the driver is at fault. May just need to be calibrated.

as t the errors -- that sounds like a wiring or power issue.

waht are you powering it with?

[pallid cliff]

3 AA batteries

power supplies are in the mail

[solar whale]

make sure they are fresh

[pallid cliff]

yup

[solar whale]

I'll try it on batteries

sorry - don't have a 3xAA availble so can't compare.

[pallid cliff]

It's all good. what CR servo are you using?

[solar whale]

FS90R

[pallid cliff]

I'm using a fitec fs5103r, and just noticed it has a trim for the zero position, so at least mine is stopping now 😛

[solar whale]

nice! but you still get the errors?

[pallid cliff]

yup, consistent errors though

one cycle through the code, then freeze

newest crickit firmware and circuit python 3.0 on the cpx with the crickit library

[solar whale]

same - here -- mine does have an adjust pot as well -- have not played with it.

Have you tried other crikit funtions -- does it typucally comunicate OK?

What are you powering the CPX with?

[pallid cliff]

dc motors are good, stepper on drive is good, standard servo is good. signal io is good. cap touch is good

USB power for CPX

It does throw "RuntimeError: SDA or SCL needs a pull up" despite the screws being on really good

occasionally

[solar whale]

DO you have a meter to check to battery voltage -- they are alkalines, correct?

[pallid cliff]

not as fresh as they were, 4.2V

yes alkaline

[solar whale]

That is not normal -- possibly worth making sure the contact to the spacers/xcrews are clean so it is maing good contact, Try new batteries . 4.2 is getting low.

just tried using 4 NiMH batteries and it works fine

[pallid cliff]

ok, contacts checked, 3 new batteries, and it's doing multiple cycles. but only 4.6V, not that much more

[solar whale]

just checked my batteries -- its at 5.2V -- they may be alkalines as well -- still much highr voltage

[pallid cliff]

might have to buy some NiMH batteries

[solar whale]

so no errors

[pallid cliff]

none yet, almost a dozen cycles in a row

[solar whale]

so I think its jsut a power issue --

[pallid cliff]

sigh, it's always the simple things isn't it? 😛

[solar whale]

it says > 4.5 -- guess they mean it!

[pallid cliff]

yeah!

[solar whale]

gotta run -- good luck

[pallid cliff]

Thank you!

[solar whale]

you're wecome

@pallid cliff it does say 4-5V so 4.2 "shpuld" work --- hopefully someone else with more knowledge of the CRIKIT power req can comment.

[pallid cliff]

alright

@pallid cliff Also measure the voltage when it's under load. It might be sagging when the servos are moving

[indigo hazel]

Is it possible to simplify this code? I am looking for a "chasing" type animation on the CPX and would like to see what other ideas may be.

[tidal kiln]

@indigo hazel easiest is to just use one of the built in animations
LIGHT -> show animation...

but another way to do what you're doing is to use the LIGHT -> show ring block

then you can individually set each neopixel with one block

also, try asking in #help-with-makecode, the makecode devs often hangout in that channel (this one is for circuitpython)

[indigo hazel]

Okay thank you.

[tidal kiln]

np. i'm just a user myself. you might get better info over there. good luck!

[raven canopy]

so much stuff to install on a new system... 😵

[tidal kiln]

indeed. always shocks me too. and you need to install stuff that installs the stuff that then runs the install scripts that installs the stuff so you can finally install the thing.

[meager fog]

@idle owl hey0 kattni since yer at a conf, maybe @tidal kiln can take a look at makecode'n the zombie game

[idle owl]

Ok. @tidal kiln? I can link you to the CP part of the guide and the code.

[tidal kiln]

think i already got it from earlier?

[idle owl]

Yes, that was the same

[meager fog]

you can TEAMUP

also, @tidal kiln you make hilarious images, please make some free-clipart CPX-zombie and CPX-nurse to demonstrate how it works?

[tidal kiln]

uh oh. thanks. but it might just be free clip art that you're already seeing?

that i just re-used

[meager fog]

yah thats what i mean

i like your mashups 😃

[tidal kiln]

ah. gotcha.

[meager fog]

https://openclipart.org/detail/237764/nurse-hat

[tidal kiln]

looks like that was made to fit

@idle owl for makecode, will probably just make three separate programs. they choose what they want to be when they drag the UF2 over. or is there a reason to have it be field changeable?

[idle owl]

@tidal kiln Not that I'm aware of, we just did the CP code in one program. I don't know that it's a requirement. @meager fog?

[meager fog]

i think for circuitpython it was easiest to do this way

for makecode its fine to have 3 programs

because you cant edit easily

so just make em fixed-usage

and they can drag the uf2 around

[tidal kiln]

zombie.uf2, healer.uf2, human.uf2 easy peasy

[meager fog]

but see how you fair!

its gonna be very easy in makecode - btw if fading LEDs is hard, just blink the neopixels instead

[tidal kiln]

oh, i see, that's for the zombie and healer

human is just a health counter, no fading (pulsing)

[meager fog]

right

[tidal kiln]

hmmmm. a human can become a zombie....that puts a wrinkle in it...

@idle owl i'll play around with it and then can just send you the makecode published links

[meager fog]

yeah @tidal kiln

[idle owl]

@tidal kiln Alright, I'm out for tomorrow and the weekend but I'll take a look at them on Monday.

[meager fog]

@tidal kiln you can also send to me - just post in basecamp

ill add ya!

OK, so, quick question. My Metro M4 Express seems to be corrupting the main.py file.

What am I doing wrong?

[tulip sleet]

what editor are you using?

[cunning crypt]

I'm editing a main.py file locally, saving it, copying it over. Verify it's correct. Reboot the device, and... corrupted file.

Notepad++, locally.

[tulip sleet]

how are you copying it over, on what OS

[cunning crypt]

Standard file transfer, Windows 10

[tulip sleet]

you have to eject after copying to force all the bits to get written

[cunning crypt]

This has worked for M0 devices previously.

Aha, OK

[solar whale]

@tulip sleet not dfu-flash -- you can use the Jlink interface and just flash

[tulip sleet]

it might look ok from the windows side but that's because windows is looking at the cache, not the actual flash

@solar whale but can I do dfu-flash at all, without jlink?

how are you "rebooting the device?" reset button or ctrl-D?

[solar whale]

not taht I am awate of -- it is not a dfu boot loader -- justa sec

@cunning crypt the filesystem could be corrupted. Don't unplug or press the reset button. Just go into the repl and type ctrl-D

to get a soft reload

[cunning crypt]

I seem to remember a board doing this and having to re-copy CP over to it.

[tulip sleet]

to fix up the filesystem, save any files you don't have backups of, and then do in the REPL:

import storage
storage.erase_filesystem()

you'll have a clean CIRCUITPY and can copy stuff back

[solar whale]

@tulip sleet I set mine up for teh MSC bootlader https://github.com/adafruit/circuitpython/tree/master/ports/nrf/boards/feather52840

[tulip sleet]

ok, wasn't sure if it included DFU also. I can use the jlink, or nrfjprog

thanks!

[solar whale]

use BOARD=pca10056 not feather52840 though

[tulip sleet]

BOARD=pca10056 SD=s140 ??

do i need the softdevice yet?

[solar whale]

to get to boot loader hold buttons 1 and 2 then RESET

[tulip sleet]

wow, where is that written down?

[solar whale]

I think the default sofdevice will be fine

it's not

default softdevice is 6.0.0

[tulip sleet]

is the MSC bootloader working now? I thought it was just for show

and not yet working

[solar whale]

it works

just checking a few things

been awhile sice I did it...

[cunning crypt]

@tulip sleet Seems to be working. Except now it's filling the character LCD with blank spaces as soon as it runs. Interesting.

[solar whale]

@tulip sleet trying to recall how I got the bootloder installed in the first place...

[tulip sleet]

I know - I did that a long time ago. It might be in the bootloader repo README.md

[cunning crypt]

Aaand fixed. Apparently the LCD doesn't like "nothing" happening.

Thanks @tulip sleet - Filesystem seems to be working great now.

[solar whale]

its on that same page - CDC boot laoader make SD=s140 BOARD=pca10056 bootloader

[tulip sleet]

@cunning crypt great. If you tire of ejecting all the time, you can use an editor that writes everything back immediately: VS Code, Atom (with a plugin), emacs, vim, Mu. NOT Notepad++ or Notepad.

[cunning crypt]

Yeah, notepad++ is for local only

When I copy the files over now, I can watch it reload in the REPL

Haven't had to eject.

[tulip sleet]

https://learn.adafruit.com/welcome-to-circuitpython/creating-and-editing-code#1-use-an-editor-that-writes-out-the-file-completely-when-you-save-it-6-13

yes, I rarely reset. I just ctrl-D in the REPL if it's not main.py.

[solar whale]

@tulip sleet it may support both dfu and MSC -- sorry -- still a bit fuzzy

[tulip sleet]

i'll try the reset +1 +2. I was just doing reset

[solar whale]

did you load the bootloader?

then switch to the nrfUSB port

[tulip sleet]

i did a couple of weeks ago

[solar whale]

comes up as NRF52BOOT

[tulip sleet]

ah, mine says FEATHER5284, so I think it's a much older version. I need nrfjprog. It's not in my PATH. (It was once but that's when I was trying Limor's versions.)

so plug in from the jlink port, and then load bootloader and then switch to nrf USB (on long edge)?

[solar whale]

yes

[tulip sleet]

which nrfutil are you using... from our repo?

or the pip install one?

[solar whale]

so I guess the dfu laoder may also still work, but have not tried it -- jerryneedell@Ubuntu-Macmini:~/projects/feather_adalogger$ nrfutil version nrfutil version 0.5.2d from the repo

It takes quite awhile to reboot after flash -- much longer tahtn SAMD -- be patient - give it 30 seconds

[tulip sleet]

ok, got 0.5.2d from adafruit/nRF52_nrfutil, but where is nrfjprog, or is that just an alias?

[solar whale]

I did not do anything special for it -- just insatlled nrfutil

it may come from Segger jerryneedell@Ubuntu-Macmini:~/projects/feather_adalogger$ nrfjprog -v nrfjprog version: 9.7.2 JLinkARM.dll version: 6.30h

[tulip sleet]

what do which nrfutil and which nrfjprog say?

[solar whale]

jerryneedell@Ubuntu-Macmini:~/projects/feather_adalogger$ which nrfutil
/usr/local/bin/nrfutil
jerryneedell@Ubuntu-Macmini:~/projects/feather_adalogger$ which nrfjprog
/home/jerryneedell/bin/nrfjprog

nrfjprog is installed locally

[tulip sleet]

k, i'll look around for where to get it from

ah, it's linked from here: https://github.com/adafruit/circuitpython/blob/master/ports/nrf/README.md

[raven canopy]

isn't it part of the SDK in the repo? (the cobwebs in my brain can't read back far enough...)

[solar whale]

lrwxrwxrwx  1 jerryneedell jerryneedell   54 Oct 29  2017 nrfjprog -> /home/jerryneedell/projects/nrf52840/nrfjprog/nrfjprog

[tulip sleet]

it's in nRFx-Command-Line-Tools. That's what the link downloads

[raven canopy]

ahh...yeah. guess i downloaded it before. 😄

[solar whale]

looks like I have not updated it recently -- must have been part of the DK setup originally

https://github.com/adafruit/circuitpython/tree/master/ports/nrf/boards/feather52840#install-nrfjprog

[tulip sleet]

wow this is spread out all over the READMEs

[solar whale]

9.7.2 is still version I have

yup! Arturo was my guide

[tulip sleet]

i installed 9.4.0, i'll look for the upate

but I have liftoff! NRF52BOOT!

[solar whale]

woohoo!

[tulip sleet]

i accidentally flipped that "nRF ONLY | default" slide switch above LED1 the wrong way and it made the board appear dead. took a while to figure that out. luckily I have two boards

[raven canopy]

@slender iron i totally just remembered about running adabot; new laptop and getting ready for vacation has consumed most of my brain. and, i'll have to figure out the credential part.

[solar whale]

too many buttons and switches on this board!

[tulip sleet]

ok REPL!

[raven canopy]

yeah, i was a little surprised by that when i unpacked mine. "oh good..more variables". 😄

[solar whale]

cool!

I like the "cheat sheet" stencilled on the back ofr finding pins

[tulip sleet]

the power slide switch is confusing. I have it in the middle, VDD. USB position does not seem to be right, though you might think that would be it

[solar whale]

I've never moved it

VDD

[tulip sleet]

when the board seemed dead, i tried that first

the point of all this was to test the merge from upstream micropython, which seems finally to be working on all platforms. Still have to run the unix tests

[solar whale]

Wow - nice!

[tulip sleet]

you might be an esp8266 guinea pig on this - but I think it's ok. Upstream changed some stuff about the serial connection and I had to change it back: they were relying on dupterm which we moved to multiterminal, but not providing the same functionality. we are drifting further and further away from upstream on various things

i spent like four hours looking at 3-way diffs to vet the merges and fix things up

ugh

[solar whale]

I've noticed taht if I try to unmount the nrf CIRCUITPY - it often tells me it has to finish writing then gives an error when I thrn it off. seems to be OK afterward, but just a heads up

[tulip sleet]

it's a completely different USB stack, so not surprising, thanks

[solar whale]

just remounted and unmounted fine so its not reproducible -- don't think it is issue-worthy -- yet

[tulip sleet]

have you tried the beta saleae Logic program yet? v nice, does realtime capture display

https://support.saleae.com/hc/en-us/articles/115005972023-Saleae-Logic-Beta-Software

[solar whale]

oohh - thanks had not seen it

just restarted reading KTowns BLE book -- determined to learn how to use it!!

too many acronyms

[raven canopy]

😟 😟

.... Running Patch Checks On 93 Repos ....

[tulip sleet]

@slender iron PR #1057 failed in travis (a long time ago); prob you know that already

[raven canopy]

hmm...well, that didn't work at all. but, its a local problem. also, it seems to not be grabbing everything (unless it's another symptom of the local problem)

.... Patches Applied: 0
.... Patches Skipped: 1
.... Patches Failed: 59

[slender iron]

@tulip sleet yup. been heads down on rom byte hunting. string compression looks promising using huffman encoding

will likely do translation support as well

qstr 4217 bytes -> 2807

[tulip sleet]

wow, you're on a roll. I think I finally finished the merge. have repl in atmel, esp8266, and nrf. still need to run unix tests

[solar whale]

Brings tears to my eyes -- someone actually remembered to test the esp8266 😉

[solar whale]

goodnight all! 💤

[raven canopy]

@slender iron @tulip sleet so the first 6 patches (initial live test) from adabot have been run for the code of conduct. successively! buuuuut, its causing Travis failures with pylint 2.0 on a few repos. do we want to run the rest of the CoC patch, and then run a patch for .travis.yml? or would you rather put up the patchfile now and then run the two patches together?

[slender iron]

@raven canopy both 😃

💤

[raven canopy]

@slender iron k. i'll grab the commit from the one Dan did and submit the PR for the patch. found something i missed that needs a PR anyway. 😄

💤 as well...

[gentle bronze]

@solar whale eject/safe remove send a scsi command which is not handled now, causing host to complain. It will be fixed in the next PR.

@tulip sleet both uf2 and cdc (dfu) works. UF2 only upgrade the firmware, cdc/dfu in addition to firmware could also upgrade the bootloader + Softdevice

[gentle bronze]

SD is defaullt to s140 for nrf52840 (feather & pca10056) and s132 for nrf52832 (feather & pca10040). That is most people do, only need to SD= for no SD usage.

[solar whale]

@gentle bronze when using CDC/dfu is it done via the J-Link USB port or the nrf USBPort?

[gentle bronze]

it is done via CDC on the nrf52840, there is no usage of jlink CDC

[solar whale]

OK so all flashing of bootlader, SD or firmware is done via the same port the one labeled nrfUSB near the BLE antenna - no need to use the one near the battery any more.

[gentle bronze]

Yeah, one you flashed the bootloader, it is self upgradable.

[solar whale]

great! thank you. That makes sense.

[gentle bronze]

Flash target still just jlink + nrfjprog, dfu-gen dfu-flash or uf2 copy if you want to omit jlink

No problem, it is confusing since we have 2 cdc, and we used to work with jlink cdc until recently

[solar whale]

OK - good -- that is what I had been doing -- since loading the botloader via Jlink, I have only updated the firmware via uf2.. I have not tried dfu or loading bootloader again. I did not realize that the dfu was an option.

[gentle bronze]

Yeah, dfu is better for scripting, we will use it for arduino repo as well.

[solar whale]

ah -- that makes sense. So the feather52840 will support both dfu and UF2 -- the feather52832 will only ever use dfu -- it cannot support UF2

[gentle bronze]

Exactly, since 832 does not has native usb hw

[solar whale]

Thank you for all the clarifications. The PCA10056 board is partiularly confusing because of the multiple ports and the various buttons and switches -- it takes some time to get used to it!

for the PCA10056 -- you have to hold buttons 1&2 down when RESETTING to get to the bootloader -- on the feather52840 will it just be a double-tap of the RESET like the other feathers?

[gentle bronze]

Yeah agreed, to get into bootloader mode, you need to press button0 while reset. Too bad double reset trick cannot be implemented if nrf5x series, at least I couldn't.

Only button1, holding 2 button will put it into dfu mode with ota support

[solar whale]

hm -- let me try again

[gentle bronze]

Button1 : normal dfu + uf2, led0 blink

Button1 and 2: ota dfu + uf: LED1 will also blink as well

[solar whale]

oh -- you are correct -- ok so 1 & 2 -- still works, jut not needed but allow OTA

[gentle bronze]

Double reset won't work since nrf5x will clear all the registers, sram mem. Nordic spents extra logic gate to make sure they are all clean. I tried but couldn't figure to do double reset trick. You are back to default when reset.

[solar whale]

OK - so the feather52840 will have to have a differnt method.

[gentle bronze]

I mean the chip is back to default

[solar whale]

Wow -- I tried button 1 & 2 and I see device adaDFU in the Bluefruit app on my phone!!

and I can connect to it!

[gentle bronze]

You can upgrade it there as well, though you need to use Nordic app, since our app does not support the pkg format (it still uses the good old init+binary)

Use the pkg .zip file created in the dfu-gen target, the same one cdc interface used to upgrade

Another note, if holding only button2 while reset, it will clear the firmware, serving as factory reset button

Only bootloader remains afterward

[solar whale]

AH -- good to knw!

[gentle bronze]

Ah, there are 2 extra ways to go into bootloader as well without using phys buttons (not implemented yet)

The 1200bps cdc touch, which is used by Arduino. And a simple command using usb control transfer

The usb control command may have a bit of driver issue with windows (needs extra step for binding libusbk driver). But it wilk work flawless under macos and linux. Can be used as part of dfu-flash target for auto update

I wilk submit a PR for bootloader update later.

[solar whale]

That sounds great! Thank you for all you have done and for how quickly this has been implemented!

[gentle bronze]

No problems, the usb stack is written for like 3 years :( . So it is not really that quick :((

[solar whale]

Not for you -- the nrf52 has gotten a quick start due to all your work!

just reading instructions in the nrf app for using OTA -- sounds really nice -- I'll give it a try when I feel brave!

[gentle bronze]

😋

For nr52, @indigo wedge did a lot more, I am just involved in usb related thing 😉

[solar whale]

It's a great team! Thanks for answering all my questions this morning ( evening for you)

[bronze geyser]

i'm trying to get up to speed on makefile. i found i was getting confused when building CP. i am trying to build a debug "hello.c" binary/cross-compile to itsy-bitsy m0version. i think my current challenge is in the linker script. i found one for samd21x18.ld w/in CP build. However, I think there is something (when defining sections?) that strips the symbols (e.g.: compile w/ -ggdb)? What am I missing? Any advice greatly appreciated.

[gentle bronze]

Yeah, not at all.

[solar whale]

@bronze geyser to build the DEBUG version just make DEBUG=1 BOARD=xxxx

[bronze geyser]

@solar whale yes. I can do that and it works great. However, i am trying to understand what is going on within a makefile since i found it confusing. so i started w/ basic hello.c then went through setting up CFLAGS, LFLAGS. I get a .elf. gdb however tells me the .elf does not have symbol files. I am not using a -s in the link stage, i do use -ggdb in the compile stage. So i thought is was the .ld file?

@solar whale - i very much thank you for your reply.

[solar whale]

@bronze geyser sorry - you are much deeper into it than I realized. Hopefully Dan or Scott can help soon.

[bronze geyser]

@solar whale i do seem to have my hip boots on. again, thank you. it was kind of you to jump in.

[solar whale]

@bronze geyser I have enjoyed following and learning from your progress. Thank you!

Anyone have any ideas as to whether this could be made to work with CircuitPython? https://github.com/pimoroni/vl53l1x-python

It's an I2C device, so it should not only be possible but pretty straightforward.

@small cypress there's a library for the VL53L0X, so it's probably just a matter of adjusting some protocol (maybe more, maybe less). https://github.com/adafruit/Adafruit_CircuitPython_VL53L0X

[adafruit/circuitpython] Issue opened: #1065 ussl on ESP/HUZZAH

I spent some time digging through why I couldn't get mqtt over TLS to work on my Feather HUZZAH. I have come to the conclusion that micropython/extmod/modussl_axtls.c is ahead of circuitpython/extmod/modussl_axtls.c.

What would it take to update this?

[adafruit/circuitpython] New comment on issue #1065: ussl on ESP/HUZZAH

@ubiquitousthey,

@dhalbert is currently working on pulling upstream down. This may be included, but I'm not sure. Also, it may not immediately be available in a stable release (3.x atm).

[tulip sleet]

@bronze geyser Hello World in this case is more like three paragraphs than "Hello World" in terms of all the supporting stuff

Getting the .ld map and the Makefile right are tricky. I'd suggest taking the existing Makefile and .ld map and pruning them rather than starting from scratch. Maybe you are doing that already.

there is also a lot of setup needed at the beginning to set up the clocks, etc. initialize the chip in other ways, etc.

[bronze geyser]

@tulip sleet thank you. i'm using atmel-samd/boards/samd21x18.ld . I leave it be. i think that is right? but i'm not getting the symbols (compile with -ggdb, LFLAGS doesn't strip symbols)....

[tulip sleet]

it's a tremendous amount to learn and understand and may not be productive if your main goal is understanding how to modify or enhance CircuitPython.

[bronze geyser]

@tulip sleet so i'm trying to take an online embedded systems course. They use Keil. I wanted to use Atom + gdb command line. I thought this would help me get a better feel for why the 2nd call to standby wasn't coming back to me (i.e.: i could use more embedded sys background).

@tulip sleet I also dorked around with Eclipse. But the more I used Eclipse, the more I gasped, particularly around managed make files. OMG!

@tulip sleet I got sad just thinking about Eclipse and Keil. And Happy thinking about Atom. I mean, i get pluggins that show me the actual colors of hex values. Now THAT is useful!

[tulip sleet]

note that when we link we use gcc to link, not ld. Not sure if you are doing it as well. The settings in the Makefile and in py/*.mk are tuned to do the right thing.

[bronze geyser]

@tulip sleet - i'm using ld because the examples i found did this. hmmm...

[tulip sleet]

Have you tried Atmel Studio? (Or maybe you don't have Windows.) Another approach is to use Atmel START to build a simple program: it generates a Makefile that does "the right thing", I believe (though I haven't tried it). https://start.atmel.com

$(BUILD)/firmware.elf: $(OBJ)
    $(STEPECHO) "LINK $@"
    $(Q)$(CC) -o $@ $(LDFLAGS) $^ -Wl,--start-group $(LIBS) -Wl,--end-group
    $(Q)$(SIZE) $@ | $(PYTHON3) $(TOP)/tools/build_memory_info.py $(LD_FILE)

[bronze geyser]

@tulip sleet i don't have Windows.... and thank you. i will take a closer look at the makefile w/in atmel-samd.

[tulip sleet]

try one of the simple examples in Atmel START as well. The config .h files are kind of a mess, but the basic .c and Makefile files are fairly simple.

[bronze geyser]

@tulip sleet Will do. I very much appreciate your time/help.

[tulip sleet]

happy to help!

[bronze geyser]

@tulip sleet - ooh YIPPEE (at least for now...?) the Atmel start goo worked... WOW...i guess the lesson for me is USE THE DARN HALL (two LLs intentional) layer.

[adafruit/circuitpython] New comment on issue #1065: ussl on ESP/HUZZAH

FYI - I checked the 3.x branch, and it is not updated. @dhalbert, let me know if you need someone to test this when you pull it in. I have pretty much ready to test it. It is currently complaining to me that I am sending kwargs that are not supported.

[upbeat plover]

what is OSError 28? is it out of space?

had CPX logging all night and finally at 0 bytes left

[loud reef]

I am new to circuitpython but I have a neopixel strip connected. It's RGBW so I was wondering if the circuitpython neopixel lib supports them.

[raven canopy]

@bronze geyser what course are you taking? I was searching the ARM offerings earlier today, coincidentally.

[solar whale]

@loud reef yes it does here is an example of the "color wheel" on a feather_m4_express -- the main change was to add the bpp=4 parameter to the configuration line ```
from digitalio import *
from board import *
import neopixel
import time

pixpin = D6
numpix = 8

strip = neopixel.NeoPixel(pixpin, numpix, bpp=4, brightness=0.3,auto_write=False)

def wheel(pos):
# Input a value 0 to 255 to get a color value.
# The colours are a transition r - g - b - back to r.
if (pos < 0):
return (0, 0, 0, 0)
if (pos > 255):
return (0, 0, 0, 0)
if (pos < 85):
return (int(pos * 3), int(255 - (pos3)), 0, 0)
elif (pos < 170):
pos -= 85
return (int(255 - pos3), 0, int(pos3), 0)
else:
pos -= 170
return (0, int(pos3), int(255 - pos*3), 0)

def rainbow_cycle(wait):
for j in range(255):
for i in range(len(strip)):
idx = int ((i * 256 / len(strip)) + j)
strip[i] = wheel(idx & 255)
strip.show()
time.sleep(wait)

try:
while True:
rainbow_cycle(0.001)

except:
pass

finally:
strip.fill((0,0,0,0))
strip.show()

or as noted here - you can spcify the pixel_order and then the bpp is set automatically -- I have not tried taht myself.

https://circuitpython.readthedocs.io/projects/neopixel/en/latest/

[loud reef]

Oh, ok. Thanks

[tulip sleet]

the default pixel order is GRBW, but with bpp=3 (it ignores the W). So do go ahead and set bpp=4

[solar whale]

@loud reef here is the full documentation https://circuitpython.readthedocs.io/projects/neopixel/en/latest/api.html

@tulip sleet the RTD implies it set bpp based pn pixel_order -- is that not correct?

Note that bpp does not need to be specified as it is computed from the supplied pixel_order.

in https://circuitpython.readthedocs.io/projects/neopixel/en/latest/

[tulip sleet]

if you specify order=GRBW, then it sets bpp=4, but if you leave order alone (as None), then it sets it to GRBW but sets bpp=3. https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel/blob/master/neopixel.py. I think the doc is confusing.

[solar whale]

agreed -- best tp specify bpp.

[loud reef]

I'll try that with the example

[tulip sleet]

It should probably say "Note that if you supply pixel_order, the bpp will be set appropriately" or something like that.

[solar whale]

It's sort of implied, since if you don't set pixel_order then it would not know bpp was 4 instead of 3, but it could be more explicit.

@tulip sleet I finally took the plunge and upgraded to Ubuntu 1804 -- so far so good -- no issues yet

[tulip sleet]

only problem I had was getting the shutter screenshot app to be able to edit. It's possible but annoying

i am using cinnamon and it's working fine with the supplied cinnamon instead of having to use a ppa.

[solar whale]

I did update the team-gcc-arm ppa to use "bionic" but I was altready at the latest version so no real change. all the boards built fine with the toolsets I have installed

@raven canopy well...i'm not sure i'd recommend it. i get up super early and love to watch videos while i walk on a treadmill. so i found this udemy course - https://www.udemy.com/embedded-system-programming-on-arm-cortex-m3m4/learn/v4/content - it caught my eye because of arm cortex-m...i figured it's better than watching some other stuff...

[upbeat plover]

My feather M0 adalogger and sensor came in the mail this morning. 😻

[bronze geyser]

@raven canopy the instructor / guy / person got into installing Keil to make main.c ... it was at that point i went down a rabbit hole saying "how hard can it be?" to do this using Atom....so just for jollies I check out someone else. They use Eclipse...ho ho...i think..i've used that before...so i go down THAT rabbit hole...but recalled...oh just how yucky managed make / etc. was and then there are all these layers... so back to "Atom - good to meet you, how hard can it be?"

@raven canopy then Atom says to me "Hey HappyDay...check out the plug in that shows all these colors..." this made me think...well, ok...but...

@raven canopy i did find https://hackaday.com/2016/03/22/embed-with-elliot-arm-makefile-madness/ very nicely written/informative. The challenge is alot of stuff is using the ST chips.. microchip's "programming to the peripherals" and such seems a tad more convoluted/complicated.

thanks for reply

[torn grail]

Just to confirm after a bunch of searching... There is no TFT support in Circuit Python, right? I have a 480x320 FeatherWing, but did not see HX8357D in the Bundle.

And I should say that I am using 8266, not M0. 😉

[solar whale]

@torn grail there is support for some TFT displays see https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display/tree/master/adafruit_rgb_display

[torn grail]

Oh, I see the hx8353.py now. Thanks!!

[solar whale]

You’re welcome

[velvet scroll]

is there a way in the REPL on a circuit playground express running circuit python to get its circuitpython version out of it? trying to determine why my installed libs files are getting that mpy msimatch

ah wait if you enter repl and reset it prints it out

sweet got it running. once youre set up this is pretty sweet

[torn grail]

When I log in to the REPL on ESP8266, I get this message: Do you?
"Adafruit CircuitPython 3.0.0 on 2018-07-09; ESP module with ESP8266"

[torn grail]

I'm still trying to make the HX8357D display work... Uploaded all the latest modules from adafruit_rgb_display and adafruit_bus_device, and have esp8266_tft_featherwing.py saved as main.py on my device. When I reboot, I see a white screen. No errors in the serial console, even when I try a hard or soft reset. Any ideas? Running 3.0.0 on ESP8266. Thanks!

O I C --- The demo script is for the ILI9341. ugh. I'll try changing it to HX8357 and see how much smoke that makes!!

No smoke, but also no fire... Still a while screen.

I guess the hx8353 is not close enough to the hx8357, so it appears that it may not be supported after all. 😦

I have several circuit playground expresses that i bought before 3.0.0 was released I flashed one of them with the new release using uf2 file. When I reset it the demo did not work. There was no indication of any errors. Do I need to refresh the /lib diretory too?

You'll need to use new bundles too, yes

@tulip sleet this is what I've been heads down on https://github.com/tannewt/circuitpython/tree/i18n now to make dinner

[inland tusk]

@idle owl You should put a note in the docs for updating from 2 to 3 that in order for the demo code to work, you need to replace the files and directories in lib with new ones from the new 3.0.0 library bundle. I mention this because I have a number of cpx's that I bought before the change over to 3.

[marble hornet]

may i ask, did adafruit opensource the bin for the as7262 flash chip? i could not find it on github or the website?

[raven canopy]

@marble hornet are you looking for the binary (?) or just the library? https://github.com/adafruit/Adafruit_CircuitPython_AS726x

[tulip sleet]

@slender iron woot! you have been on a tear! I noticed micropython is commented out. Is that temp?

[raven canopy]

also, your "flash chip" may have me confused. i couldn't find a flash chip with that part number...

[raven canopy]

@marble hornet after looking at the datasheet, i understand what you're asking now. per the sheet, the software comes from the manufacturer (ams). i looked on ams's website and didn't see any downloads available. i imagine the license is proprietary and restricted to release...

hmmm from adafruit_crickit import crickit is triggering a memory allocation error - do I have to remove libs from the bundle to be able to run this?

(circuit express w/ crickit)

  File "code.py", line 4, in <module>
  File "adafruit_crickit.py", line 58, in <module>
MemoryError: memory allocation failed, allocating 235 bytes

it seems like its in the library itself

[raven canopy]

@velvet scroll are you using the CPX Crickit firmware?

https://github.com/adafruit/circuitpython/releases/download/3.0.0/adafruit-circuitpython-circuitplayground_express_crickit-3.0.0.uf2

[velvet scroll]

im using cpx bundle for v3 of circuit express

[raven canopy]

that firmware has the Crickit library "frozen" into the firmware to keep available space to a maximum.

[velvet scroll]

ah so switch it out with the current one?

from the 3.0 bundle?

[raven canopy]

yep. that link is to the 3.0 version.

[velvet scroll]

do i throw that into the lib folder?

or top level?

[raven canopy]

no. that is entirely different firmware. so go into bootloader mode (CPLAYBOOT) and drag that over.

[velvet scroll]

ah i see. ok one sec

yeah that did it

stupidly i had a motor with a wheel plugged in

so naturally it dove off the table haha

[velvet scroll]

now to bother you with one more - why is it asking to enable a pullup resistor butn ot list that in the given examples? (Setting up a servo now)

oh

[gentle bronze]

@bronze geyser you may be interested in segger embedded studios as well. It is better than Keil in many ways. No limit for personal usage, debugging is super easy as long you have jlink.

[raven canopy]

if i'm being honest, i've been spoiled by Atmel Studio...

[gentle bronze]

Those vendor-specific is all nice, though I hate switching IDE when switching mcu :)

Keil is still look like 9x GUI 😁😁

[raven canopy]

understandable. i've only worked the SAMDs at this point. i will need to figure something out if i ever dive into the nRF; still haven't even plugged in the DK yet. 😄

*esp doesn't count, since its pretty much flash and hope...

[slender iron]

@tulip sleet yup, just experimenting

[gentle bronze]

Yeah, I would hope to just use Segger Studio for all mcu now. It is still gcc, so we have option to compile with makefile project with ease and decent debugger tool

[raven canopy]

@slender iron in case you didn't see it, i put in the PR for adabot. once that is merged, i'll run the full monty. i have a suspicion though that the patch script is going to need some additional GitHub API handling for the data throttle; i've seen mixed numbers of repos when running tests.

@nocturne sluice there is no WiFi support for that board in CircuitPython. You can run CP on it - use the Feather M0 Basic image. The only WiFi support is for the ESP8266.

hello everyone

[solar whale]

@proven bluff Hello

[tulip sleet]

@tawny creek you can just look at atmel-samd/boards/*/pins.c to see how other boards do the mapping. The general idea is to maximize available functionality, such as exposing a set of pins that can be used for a particular SERCOM, etc. It's kind of tedious. Ladyada calls this pin sudoku, because changing one pin usually has a ripple effect.

[proven bluff]

how do I debug print to serial from within the C code in circuit python? I'm running my code on Feather M0 Express if that matters.

[solar whale]

@proven bluff I'm not sure I unerstand what you are trying to do. Can you provide an example?

[proven bluff]

So I'm in the middle of shared-modules/os/init.c, I don't have a JTAG debugger and I wanted to use a printf like function to display some values.

[solar whale]

I thought you could just use printf @tulip sleet is there any reason not to just use printf ?

[tulip sleet]

a simple printf() is not usually available but mp_printf(&mp_plat_print, "%d %d", i, j) is

[solar whale]

thanks - does DEBUG=1 enable simple printf? I thought I saw some examples using it

[tulip sleet]

i don't think it's across everything; there are some files that define a printf() macro when a debug flag is enabled

[solar whale]

ah --thanks -- sorry for the confusion.

Hmm, is uctypes a built-in library? I can't seem to find it in the downloads, but importing it in my code gets "ImportError: no module named 'uctypes'"

[timber mango]

what's the context, @small cypress

One time I used 'ag' on an entire source tree only to find what I was looking for was enumerated in the same file I was working on. ;)

[small cypress]

looking to get this working in CP: https://github.com/pimoroni/vl53l1x-python

[timber mango]

Do you have a paste or screenshot of the error in context?

[tidal kiln]

@small cypress uctypes is a micropython thing:
http://docs.micropython.org/en/latest/pyboard/library/uctypes.html
which is their small size optimized implementation of the full Python ctypes module:
https://docs.python.org/3/library/ctypes.html
which is what the library you linked is using

[small cypress]

http://circuitpython.readthedocs.io/en/3.x/docs/library/uctypes.html is my confusion

[tidal kiln]

yah. that may be out of date. sry 😦

see the warning though

you're running into one of the micropython vs. circuitpython differences

i think it was originally left in early on, but not sure what current status is

[stuck elbow]

it's actually still there

it's only available on the unix port, though

because it doesn't make any sense on a non-Von Nemann architectures

[tidal kiln]

and that driver looks like it's a python wrapper for a C library

@small cypress this may provide a useful reference / example of what would be required for circuitpython:
https://github.com/adafruit/Adafruit_CircuitPython_VL53L0X/blob/master/adafruit_vl53l0x.py

[raven canopy]

@small cypress did you look at the existing CircuitPython VL53L0X library? I would work from that, and adjust any of the protocol functioning...

[proven bluff]

another newbie question: how do I run all the tests I can? tests/run-tests passes with 33 tests skipped

[small cypress]

hmmm might try that

[proven bluff]

I don't want to make a PR with some test failing

[tidal kiln]

@small cypress and compare it to the arduino version so you can see what it looked like originally:
https://github.com/adafruit/Adafruit_VL53L0X

[raven canopy]

@proven bluff if you setup a TravisCI account, and link it to your forked repo, it will run all the tests.

@small cypress could you file an issue about uctypes being in the doc but not in any build? Thanks.

@fathom trellis I see that's a warning converted to an error. You could remove -Werror from the Makefile.

make sure you did git submodule update to get the latest axtls

I don't see that issue when it's compiled on Linux

so it may have to do with your build environment

This is in the Makefile: CWARN = -Wall -Werror

[idle owl]

@tidal kiln Greg said he'd try it again tonight, but I'm not sure he'll have time. If I don't get him to do it, I'll try to recreate it when I get home. He's super new to CircuitPython so I'd need to walk him through recreating it.

It was failing on line 77/78 of stepper.

[tidal kiln]

@idle owl i think i see it. looks like a bug.

[idle owl]

@tidal kiln That's what I thought

[fathom trellis]

@tulip sleet -- My submodules were already up to date. I just pulled them down when I forked the project today. Your tip worked, and the build completed successfully. My environment is OSX High Sierra

[tidal kiln]

@idle owl lots of layers, pretty convoluted, but i'll try:
adafruit_motor/stepper.py in StepperMotor __init__:

self._coil[i].frequency = 2000

where _coil is a tuple of outputs that should support PWM. However, in adafruit_featherwing/motor_featherwing.py, the stepper is created with something like:

self._stepper1 = stepper.StepperMotor(self._pca.channels[10], self._pca.channels[9],
                                      self._pca.channels[11], self._pca.channels[12])

and _pca is a PCA9685 instance. So we look there. In adafruit_pca9685.py, .channels is a PCAChannels instance, the accessor of that returns a PWMChannel (from the same adafruit_pca9685 module). That class has a frequency property, but no frequency setter.

woo. that's a quick brain dump. let me read through it and edit if needed....

[idle owl]

Right. Needs to be set to True I thought. I figured it was a change from 2.x

[tidal kiln]

this is the problematic class:
https://github.com/adafruit/Adafruit_CircuitPython_PCA9685/blob/master/adafruit_pca9685.py#L60

but i'm not sure if the problem is that class's lack of a frequency setter, or if adafruit_motor/stepper.py is doing something wrong.

my guess is the former

or, to put it another way, this would work:

print(self._coil[i].frequency)

but this doesn't:

self._coil[i].frequency = 2000

the other important detail is that the PWM support is coming from the PCA9685, and not a built in PWM channel.

i.e., you're using adafruit_pca9685, not pulseio.PWMOut

@idle owl it might be an easy fix, if you want to try??

@tulip sleet just pulled PR1068 and am buildiing boards -- tried CPX crickit - no problems yet.. Anything in particular taht it would be helpful to try?

[fervent fog]

hi lady ada and friends 😃

[tulip sleet]

@solar whale thanks for testing. esp8266 merge was not easy, so if you can try some things, esp network, filesystem, and repl-related, that would be great. nrf could use more testing too but that is undergoing enough change that I'm not as worried about breaking it. I'm still trying to get the docs build to work and I think I will remove the qemu-arm build -- not sure it is useful for us anyway. I tried it locally and qemu itself crashes (!).

[solar whale]

OK -- I'll concetrate on the ESP8266 and nrfs

[drowsy swift]

@timber mango Would I switch the vusb to my vout to get the 5v needed? https://learn.adafruit.com/i2c-spi-lcd-backpack/circuitpython-code and are the connections scl and sda universal across boards? (I don't know what they stand for)

[timber mango]

HD44780 is a chip used on many (not all) character LCD's.

It needs I think 6 pins back to the microcontroller, plus power, ground, and especially, a 'contrast' line (not controlled by the microcontroller).

The backpack saves you a lot of wiring, but if there's enough GPIO on a given board, you can drive it 'manually'.

@drowsy swift Not sure I understood all that.

Signals (pins) SDA and SCL are specific to a two-wire serial protocol called i2c (inter-integrated circuit; aka iic or SMB).

[drowsy swift]

@timber mango doesn't look like I understand much here either 😃 This is what I have to work with https://learn.adafruit.com/adafruit-circuit-playground-express/pinouts

[timber mango]

Voltage levels can be a problem; I don't remember offhand what the elegant solution is for a 3.3 volt target board such as the Circuit Playground Express.

You may need a level shifter IC such as 74HCT125 (let me look that up for sure).

http://adafru.it/1787 74AHCT125 buffer (level-shifter).

[fervent fog]

wow all you care about is a stupid microchip 😛

[timber mango]

@drowsy swift Well you want to look at i2c and SPI and GPIO on the pinouts page of the learning guide for the Circuit Playground Express.

https://learn.adafruit.com/adafruit-circuit-playground-express/pinouts

8 GPIO (general purpose Input/Output) pins. That's more than enough to drive a character LCD using a 4-bit parallel interface.

Not sure if you can (easily) do SPI (Serial Peripheral Interface) with the Circuit Playground Express (CPX) or not. @solar whale or @tulip sleet would know (several others as well).

[drowsy swift]

So all of the pins are GPIO? I don't have to use them for their printed purpose? like I don't have to use a6/rx for rx?

[timber mango]

No just about (if not every single) port pin is GPIO on most boards. There may be one or two exceptions but I can' t think of any at the moment.

I'm not used trying to squeeze an extra GPIO pin out of a given system, so I may be mistaken.

The silcscreen labels are unknown to the microcontroller. ;)

In the case of an analog input, you are not going to see that on every single pin by any means.

[drowsy swift]

Ahhhh fantastic!

That helps a bunch @timber mango

[solar whale]

@timber mango at first glance , i don't see the SPI pins broken out on the CPX -- I have not tried it. SPI is used for some of the internal sensors.

[timber mango]

Traditionally any pin good for GPIO (including ones you don't get a solder pad for) are labeled D1 D2 D3 and so on, somewhere in documentation.

These correspond 1:1 with the Arduino IDE development environment.

@jerry I just don't remember if software SPI is used for CPX projects or not.

@drowsy swift you don't need hardware SPI to do SPI projects but they won't run as fast, and there may be software issues you'd have to resolve less easily.

[solar whale]

@timber mango -- hold on -- I think they are there - just not in the guide -- still looking

[drowsy swift]

Is there a good resource I can use to learn more about this stuff? Buried somewhere in the adafruit site or elsewhere? Seems like most of the pages I've come across are only so technical

[timber mango]

SCL and SDA are SERCOM 5.1 and SERCOM 5.0 (respectively).

@drowsy swift I skip over a lot of introductory matter, but any article in the Learn site that has a @idle owl byline is going to be good for you. ;)

Once you are not swimming in new terminology it starts to make better sense.
I would personally start with the basics, to get comfortable with very simple expectations, such as uploading the firmware and how that system (all by itself) typically behaves.

This way you get a gut feeling for when it's not performing as expected.

Get a Parts Pal, too.
http://adafru.it/2975

[solar whale]

@timber mango -- in the pins.c https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/boards/circuitplayground_express/pins.c board.SCK,board.MOSI,board.MISO are A1,A3,A2

[timber mango]

@solar whale right right right

[drowsy swift]

Awesome, I had the built-ins page next on my list to read. I had finished the first round of setting it up yesterday, adding libraries, trying repl and all...Lol, before you linked the parts pal, I was thinking you meant an actual person

[timber mango]

haha yeah Howard the Parts Pal .. he visits here right after the Mac Tools guy leaves ;)

I have a ST7565 wired (and working) to CPX.
http://adafru.it/250

[drowsy swift]

oooo that one is nice

[timber mango]

It is at least technically an SPI device.

I am not able to remember a thing about how I programmed it -- oh wait I wrote a Circuit Python driver for it (or a direct program in CircuitPython, anyway)

I also did one in the Arduino IDE (probably used an existing Library that LadyAda wrote aeons ago)

I even got the Adafruit graphic working on it.

Unpublished because at the time I hadn't understood github very well, and was mixed up about intellectual property right and so forth.

[drowsy swift]

Sounds like you've been doing this for a while now?

[timber mango]

I have to leave the house. Ask in #general-tech and in #help-with-projects if your questions aren't very much related to #circuitpython-dev -- ask those (and any difficult SAMD21 or SAMD51 hardware questions) right here, in #circuitpython-dev .

@tulip sleet never-mind ----I repeated the build -- including reflash of the bootloader and now it works ...... will try a few more tests

[solar whale]

I'm confused -- It now works with both the default SOFTDV_VERSION (2.0.1) and (5.0.0) -- I had flahed both the bootlader and the image a few times earlier when it failed --- looking at history to see if I had somehting wrong -- in any case, its fine now -- REPLOK -- it does a BLE scan -- ampy works

[tulip sleet]

i myself have not internalized what needs to get built and loaded with what

on the nrf boards

[solar whale]

or I should say ampy works as usual -- still some ampy issues with ampy the nrf port -- but not new

the defaults should be OK , but I have been using the SOFTEV_VERSION 5.0.0 on the 52832 -- just to be cool 😎 I have no idea what the diffences are. pca10056 defaults are fine s140/SOFDEV_VERSION 6.0.0.. 52832 uses SD=s132

ampy "get" does not work on the nrf's -- I think there is an issue open already -- I'll verify

https://github.com/adafruit/ampy/issues/47 note sure if this is really an ampy issue or a CP issue -- the nrf port does not have sys.stdout

[languid sage]

Hi All, Just got Adabox008, and thought I'd build a proper bump-bot. I saw JP's Carnival Bumper Car bot, and the Ruiz's Brothers' Lego Crickit rover, but both of those use MakeCode. Not that I'm against new fangled programming tools, but I'd really feel at home with C (as in Arduino) or some flavor of Python (as in derived from C) or anything else that is of that ilk (procedural, structurable programming language). I'm most familiar with languages such as these, as I've been around since Fido's grandaddy was a tiny pup (actually, JFK was President when I took my first programming class). So my question is: is there a piece of code that I can use to build a bumper car bot program that is written in CircuitPython, or Arduino that I can use with a Crickit (either the CPX or the Feather version) and where do I find it? Circuit Python on CPX would be best, as I can make use of all of the CPX on-board goodies as my desire to add totally cool and useless features (i.e., creeping elegance) to the bot. My goal is to provide this bot, as a ruggedized toy to my 1-year old twin grandkids. - Thanks

Still playing with automated testing. Current project is automated board detection using the logic from mu. Does anyone have a suggestion for a high quality large (10 to 15 port) powered USB hub? My cheap 5 port unit is not up to the task 😦

[slender iron]

@torpid goblet I like plugable's hubs

[torpid goblet]

@slender iron thanks I'll look them up.

@slender iron Does https://plugable.com/products/usb3-hub10c2/ look sane?

[solar whale]

@torpid goblet On my Linux system, I have had problems with connecting to CP devices via USB 3.0 hubs. USB 2.0 hubs work much better for me. Of course, you mileage may vary ;-)

[torpid goblet]

@solar whale thanks. From a testing point of view would their be a difference USB 2.0 and 3.0? If so I will go with 2.0 to avoid the hub trigging extraneous errors.

[solar whale]

The only testing impact I have seen is that it won;t connect on the 3.0 hub 😀 I have not ut a lot of effort int testing this. I t was jsut simple to use a 2.0 hub. I hope others can comment on their experience.

[torpid goblet]

@solar whale thanks, What About doing hard reset. I was looking at splicing a relay into the power lines of the USB cables to be able to do hard resets. Would that be useful or is that getting too carried away?

[slender iron]

I have two of their 7 port hubs. they are usually 4 port hubs daisy chained internally

[solar whale]

my hub allows me to cut the power to each port. That comes in handy. It does not cut the data lines which can be problematic if the poard is externally powed, then it connects even if the port is "off". It is a vety inexpesive 4 port belkin hub.

Is there a CircuitPython driver for the new miniTFT OLED https://www.adafruit.com/product/3321 I thoughtt I saw one, but cant' find it.

[opaque patrol]

@solar whale I haven't seen one. What IC is the display driver?

[solar whale]

still trying to find that out -- not finding a lot of information

[opaque patrol]

It might be using this display -> https://learn.adafruit.com/adafruit-mini-tft-0-dot-96-inch-180x60-breakout/

not sure if that helps

[solar whale]

yup - just found that as well -- may be relevant!

[stuck elbow]

it's st7735

same as the bigger ones

[opaque patrol]

But the joystick feather wing says it uses I2c not SPI

[stuck elbow]

it uses both

i2c for the joystick and spi for the display, afaik

hard to say for sure with no docs or schematic

[solar whale]

@stuck elbow Its not clear to me how to set up the RGB driver for this - It support the st7735, but since this goes through the seesaw, I'm not sure how to configure it.

[stuck elbow]

the display doesn't go through seesaw

Just looked at it though, don't see the tft

[solar whale]

yes - tahts a different board -- getting closeer though!

https://www.adafruit.com/product/3632

Look at the image showing the back of the board (or look at the board) and you can see which pins are connected to CS and DC and that there are solder pad to change them

[solar whale]

yes - I see the CS/DC, but are thsose for the display or the TFT -- don't seem to work for the display.

[opaque patrol]

This is what I have for the 1.44" display, just need to change the rst pin...```
dc = digitalio.DigitalInOut(board.D5)
cs = digitalio.DigitalInOut(board.D6)
rst = digitalio.DigitalInOut(board.D9)

cs.switch_to_output(value=1)
spi = busio.SPI(clock=board.SCK, MOSI=board.MOSI, MISO=board.MISO)
spi.try_lock()

spi.configure(baudrate=24000000, polarity=0, phase=0)
spi.unlock()

cs.value = 0

display = st7735.ST7735R(spi, dc, cs, rst, 128, 128)

Change the screensize too

[solar whale]

my confusion is that apparently te RST goes through the seesaw , but I have no idea how to configure taht -- I'm just missing something fundamental here.

@opaque patrol Thanks for trying to help -- As I noted, I' am missing some baisc understaning of how this board works -- maybe more coffee will help.

[opaque patrol]

This is one I want to get, they sold out really fast

[solar whale]

I was lucky to get one, now just need to make it work! When I ordereed it, I could have sworn I saw a new driver or some other info pop up but I can't find it now...

@solar whale ☕ always the answer. I'll ask dean about the board when he gets in

Saw a new wing added to boards....don't want to say the name in case it is supposed to be secret

[solar whale]

so - just to add to my confusin regarding the miniTFT - I thoght I'd just try an I2C scan ```Adafruit CircuitPython 4.0.0-alpha on 2018-07-21; Adafruit Feather M4 Express with samd51j19

import board
import busio
i2c=busio.I2C(board.SCL,board.SDA)
i2c.try_lock()
True
i2c.scan()
[94]

but seesaw is typicaly at 0x49 (73 decimal) not 94 -- 0x5e.

it makes sense taht this would not use the "normal" seesaw address, but without some documentation its a bit confusing!

[main meteor]

Reminds me of an undocumented knockoff RTC board, so I ran an I2C scan on it and got back 2 addresses. Then I realized it included a flash chip as well.

[solar whale]

there is hope https://github.com/adafruit/seesaw/blob/master/boards/miniTFTWing/board_config.h

Seems to heal a lot faster than the CircuitPython version did. Assuming that was intentional?

[solar whale]

@narrow igloo What are you trying to do? Do you mean in a Python Script ? There is no "inline assembler" available via Python

[stuck elbow]

MicroPython has it, I wonder if it was disabled in CircuitPython

[idle owl]

@tidal kiln That last update is working consistently.

¯_(ツ)_/¯

hmm

No, it isn't.

I let it sit for a bit, and then it did the same thing.

Roger. Missed that overlap.

[solar whale]

@stuck elbow @narrow igloo sorry --I may have misspoke (mis-typed) @stuck elbow can you point to how to use it?

I don't see it ``` >>> dir(micropython)
['name', 'const', 'opt_level', 'mem_info', 'qstr_info', 'stack_use', 'heap_lock', 'heap_unlock', 'kbd_intr']

hmmm - it may be port dependent -- on the atmel build #define MICROPY_EMIT_INLINE_THUMB (0) but the esp8266 #define MICROPY_EMIT_INLINE_XTENSA (1)

no - I don't see ,icropython.asm in the esp8266 either ```Adafruit CircuitPython 4.0.0-alpha-866-gbfbb5cde5 on 2018-07-29; ESP module with ESP8266

import micropython
dir(micropython)
['class', 'name', 'alloc_emergency_exception_buf', 'const', 'heap_lock', 'heap_unlock', 'kbd_intr', 'mem_info', 'opt_level', 'qstr_info', 'schedule', 'stack_use']

Here is the doc for in assembly with micropython -- http://docs.micropython.org/en/v1.9.3/pyboard/pyboard/tutorial/assembler.html#

the same exists for circuitpython http://adafruit-micropython.readthedocs.io/en/latest/docs/pyboard/tutorial/assembler.html so I think I gave you some bad advice @narrow igloo

@opaque patrol @stuck elbow Ive been trying this code on the miniTFT with no luck -- do you see any obvious problems? ```import busio
import board
import digitalio
import adafruit_rgb_display.st7735 as st7735
from adafruit_rgb_display import color565

cs_pin = digitalio.DigitalInOut(board.D5)
dc_pin = digitalio.DigitalInOut(board.D6)

spi = busio.SPI(clock=board.SCK, MOSI=board.MOSI, MISO=board.MISO)

Initialize display

display = st7735.ST7735(spi, cs=cs_pin, dc=dc_pin, width=160, height=80)
display.fill(color565(0xff,0,0))
display.pixel(64,64,0)

the screen just powers up all white and does not respond to anything I do -- no erros, just no respone

[main meteor]

If that's your whole code, it's probably because it runs it, then falls off the end. Try adding a while True: to keep it from exiting. Guess how I know about this failure mode...

[solar whale]

It's not supposed to loop -- Just set the color to red and one pixel to off.

[main meteor]

Mine was similar, I set some Neopixels and then exited, but it didn't work. Apparently when the program exits, the objects are freed, and the destructors are called. So the trick is to keep the program from exiting.

[solar whale]

hmm - worth a ry

well - it does not exit, but no change on the display 😦 had my fingers crossed

[main meteor]

Rats, I was hoping it was that easy.

Thanks for trying!

Oh, and to the HVAC tech who arrived just in time to replace the outside compressor before the worst of the heat wave. He not only dressed every wire with cable ties, he also took the time to teach me how to remove and recharge the refrigerant – at no extra cost. Free training!

woo woo rotary encoder guide

[errant grail]

Very cool guide @tidal kiln .

Put software development on hold (again) this week in order to complete a redesign of the Crunchable Synth PCB platform due to some mechanical issues with TS and TRS jacks. It’s tough to find vertical PCB-mounted TS and TRS jacks with the same height dimension. Alas. Using the experience to continue to fine-tune my KeyCad (sic) skills.
Led an SMD hot-air soldering/rework workshop at the local makerspace last week. Was surprised to see the interest level. Although all attendees have hand-soldered SMD components in their projects, none had made the next step to hot-air soldering. Lots of oohs and ahhs when the solder paste flashed and components aligned themselves.
This week’s work will be sponsored by CircuitPython and Ancestry.com. The synth code and associated library should be done by Thursday. Need to put on blinders after that and wrap up the ancestor search so that I can stop paying the subscription fee. I now know where we came from and was able to dispel a couple of fantastic stretched stories that usually make the rounds (and are amplified) during the family reunion.

SAMD51 difficulties w/ Atmel Start

https://github.com/wa1tnr/sandboxx/blob/master/AtmelStart.d/cp_meeting_SAMD51_atmel_start.txt

Working on SAMD51 with Atmel Start. GPIO toggle is inoperative - cannot seem to blink D13 (PA23) for the Adafruit Feather M4 Express target board (which runs Arduino IDE code just fine).

Notes per the above 'sandboxx' repository on github.com.

Using ORIGIN 0x4000 (not 0x2000 like on SAMD21). SAMD21 GPIO in Atmel Start working just fine.

Target MCU is SAMD51J19A - Feather M4 Express.

follow-up code:

Yes, looks like you have a nice neat solution, just had to do some fiddling to make it work. The daughterboard trick makes assembly more complex, but gives wonderful freedom in fine-tuning connector position.

Example release notes.

 
To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://github.com/adafruit/Adafruit_CircuitPython_Bundle).

Read the [docs](http://circuitpython.readthedocs.io/projects/rtttl/en/latest/) for info on how to use it.```

test points
http://adafru.it/3824 rocks.
I'm using them with wire wrap wire. I bolt the Feather M4 Express
to a piece of perfboard, and 'thread' the wire wrap wire up through

the perfboard and thru the plate holes of the Feather, then push in a test point.
Holds really well and secure when stabiliized like this.

[solar whale]

they are great -- I've used them for quick - first test of boards before soldering on headers.

[timber mango]

I also found the Extra Long Pin Headers work really great for mounting perfboard onto a breadboard.
Just fold over the pins on top, so that the perfboard is permanently mechanically secure to the Extra Long Pin Headers.
Holds really good -- a row of 16 pins (singleton) is enough to keep the Feather M4 Express from wiggling around on the solderless breadboard.

I'm hardware oriented. From 8051 development.

I do SAMD series only (and legacy 8051 work) and am mostly interested in the core (or kernel) development.

[errant grail]

Yes. Pick a shape and scale it rather than start with a pixel.

... and support vector and raster forms natively.

Borland with their Turbo Pascal implemented turtle graphics to teach young people drawing on-screen under program control.

turtle_up, turtle_down (pen up/down) turtle_left turtle_right (to rotate where the turtle is aimed and turtle_walk (making these up but I think I'm close).

Turtle graphics originally were used with the Logo programming language. They're coming back because these days it's easy enough to build an actual "turtle" robot that carries a pen around.

[timber mango]

Right. Turbo Pascal 'borrowed' the idea and implemented it.

sounds like a saw

[adafruit/circuitpython] New comment on issue #1072: Using PulseIn to detect pin interrupts

@tannewt and I discussed this. He suggested that we add a .value getter property on PulseIn, so you could just read the current value. We might read the pin directly, keep track of the value in the interrupt handler, or calculate the value based on the count. Does this sound like it would solve your problem?

We would like to implement interrupts, but doing interrupt handlers is a big topic (storage management, etc.). There's the MicroPython model but we'd like something more beginner-fri...

@solar whale if it's all white, then probably reset pin is wrong

@uncut coral it would be all randomly colored otherwise

[solar whale]

@stuck elbow thanks -- any Idea how I can control the RESET Pin? It is set to None now, but I don't know how it routes through the seesaw. At least it is not clear to me that I do.

[stuck elbow]

it's through the seesaw, I think

you just have to pull it up

[solar whale]

right, but I don't know where it is on the board

does it use the same RESET as the processor - I could just try holdig that up. teh board silkscrees shows RESET at teh same place as the MCU RESET

[stuck elbow]

no

[idle owl]

No it's not going well at all.

The Crickit CPX is a standalone target board -- its reset button acts like any other target board's does.

[adafruit/circuitpython] New comment on issue #1072: Using PulseIn to detect pin interrupts

Yeah I think a value property could do it. If I haven't seen any pulses since init, I can just check the value to catch that first edge.

I forgot about pull up, can we add a pull property as well or a kw arg to the contructor?

[solar whale]

@timber mango true, but not on the feather versions

[idle owl]

I reinstalled Ruby. Now I can't even run gem update --system because I don't have permissions, which is what the instructions say to run, without sudo.

[solar whale]

the RESETS are tied together -- on a feather crickit, doubletapping the feather also puts the crickit into bootloader! You have to reset it after uploading a new .uf2 to the feather

[timber mango]

hehe that's weird @solar whale

[solar whale]

well, different - at least 😉

[stuck elbow]

@uncut coral I mean the reset of the display

[solar whale]

@stuck elbow understood, but I don't have a pinout or schematic for the featherwing and I' dont know where it is.

[stuck elbow]

I know the pinout of that display, if that helps

you could maybe probe it...

[gusty kiln]

@idle owl hrm. it more or less makes sense to me that something like gem update --system would require sudo, but i am quite a ways removed from regular macos usage.

[stuck elbow]

https://ae01.alicdn.com/kf/HTB1cnfve4GYBuNjy0Fnq6x5lpXaM.jpg

you want pin number 6

[idle owl]

@gusty kiln It makes sense to me too, but the problem is it seems like it's updating things to belong to root.

Or they already did

[stuck elbow]

no, wait, that's the wrong one

https://ae01.alicdn.com/kf/HTB1Masxd46I8KJjy0Fgq6xXzVXaH.jpg

this one

[gusty kiln]

root ownership should be fine, but it definitely seems odd that the perms are restricting you from executing them.

[stuck elbow]

but it's still pin number 6

[idle owl]

ah hmm.

[gusty kiln]

it's possible that you're expected to use something like rbenv at this point: https://github.com/rbenv/rbenv

I'm trying that now

it is not intuitive.

I can't get it to use the env.
