tulip sleet
#

so I need to make sure it works ๐Ÿ˜ƒ

slender iron
#

ok cool! good idea

#

ya, I'm trying to learn from alpha.4

#

trying displayio with a full color oled now

tulip sleet
#

vg

slender iron
#

heh, looks like I didn't enable displayio for all m4s ๐Ÿ˜ƒ

pastel panther
#

@slender iron should the non-adafruit m4 board designers add the displayio define themselves or are you going to add them?

manic glacierBOT
slender iron
#

@pastel panther I'm changing it to be on for anything that qualifies as "express"

#

so it should be inherited

pastel panther
#

coolio

gusty topaz
#

Guys, quick question: Can I install Circuitpython to the Adafruit Feather M0 Adalogger just like I would on a Feather M0 Express? (there are both bin and uf2 files in the Circuitpython 3.x repo).

pastel panther
#

@gusty topaz I believe there is a build specifically for that board

#

looks

slender iron
#

the adalogger may not ship with the uf2 bootloader

pastel panther
#

I am wrong, it doesn't look like there is a build for it

tulip sleet
#

I think some newer adaloggers may have shipped with a uf2 bootloader. If you doubleclick, do you see ...BOOT as a mounted drive?

gusty topaz
#

Well... I haven't bought it yet, I'm doing some research before buying it.

#

There is a uf2 file in the repository...

tulip sleet
#

there is a 3.x build for it. However, it doesn't have an external flash chip on the board, so you'd be very limited as to the CIRCUITPY filesystem size (64kB).

gusty topaz
tulip sleet
#

also, the build is missing some features in order to make room for the on-chip CIRCUITPY. You may want to get a Feather M4 Express and an Adalogger FeatherWing. That would give you much more RAM (due to the M4) and flash (due to Express)

gusty topaz
#

@tulip sleet That's an excellent point...

tulip sleet
gusty topaz
#

or I can just get the SD card SPI breakout... which is cheaper, right?

tulip sleet
#

by $1.45

gusty topaz
tulip sleet
#

the wing is a lot more convenient. Just don't forget stacking headers

#

or at least female headers, if not stacking

#

and you're not breadboarding it

gusty topaz
#

Well that's the thing... I have a trippler with a GPS featherwing, a Lora featherwing and an M0 Express already setup (no stacking headers ๐Ÿ˜ฆ )

tulip sleet
#

you want to add the adalogger to this setup?

gusty topaz
#

yep

tulip sleet
#

so buy the adalogger wing and a set of stacking headers, and you can put it underneath one of the existing boards on the tripler

#

and if you want more RAM, buy a Feather M4 and put the stacking headers on it, substituting for the M0

pastel panther
#

(and speed)

gusty topaz
#

you. are. a . genius.

pastel panther
#

pro tip: electrons can go up and down

tulip sleet
#

i just always get stacking headers for pretty much everything

gusty topaz
#

yeah, buying the stacking headers and the adalogger is the way to go. I guess I'm OK with the M0 on speed and RAM. I've had it for a while and wanted to use it for a project.

tulip sleet
#

you probably want it underneath anyway due to the radio antennas wanting to be uppermost

pastel panther
#

I should make a feather doubler doubler

tulip sleet
#

you can take a tripler and put stacking header on one end and plug it into another tripler, and then it will fall over (so get some standoffs

pastel panther
#

right

#

it's feathers all the way down!

gusty topaz
#

hmm I was thinking putting it underneath the M0.. that way the GPS geatherwing and LORA are by themselves on the other end.

#

@pastel panther i await your SAMD Beowulf cluster on S&T. ๐Ÿ˜†

gusty topaz
#

I wanted to keep the build as flat as possible. I guess it's not going to be that flat after all (I'm already using short headers).

umbral dagger
#

I'm still wishing for short stacking headers.

gusty topaz
#

On one of my previous projects I used a doubler with two levels and it ended up being pretty chunky:

umbral dagger
#

Are there any displayio examples floating around? FeatherM4 + the 480x320 TFT wing

gusty topaz
pastel panther
#

not sure if those are the same display; you might have to steal the init bytes from the driver if not

#

@gusty topaz looks clean

gusty topaz
#

@umbral dagger yeah, short stacking headers would be sweet. I was almost sure they were available... I guess I'm wrong.

#

@pastel panther thanks, but it's a bit chunky.

pastel panther
#

@gusty topaz you 3d printed the case ?

umbral dagger
#

@pastel panther Does that work with Alpha5 or do I need to built head?

gusty topaz
#

@pastel panther yep.

pastel panther
#

I think you need master

#

or close to it

gusty topaz
#

I designed it and printed it.

pastel panther
#

@gusty topaz if you really want to go flat, you can diy your own feather tripler with perf board and solder directly to it without the female headers

gusty topaz
#

hmmm yeah, you are right...

pastel panther
#

I've pretty much stopped using a breadboard for many things and just pull out the perf board. Ain't no one got time for loose jumpers

gusty topaz
#

You are courageous... I can do some serious damage if I attempted to DIY a trippler with a perf board...

#

Are there any advantages of using the featherwing adalogger over using the SD card breakout?

@exotic pumice, oh, looks like I'm using the bnahill repo (see the .gdbinit file). Maybe they took back scott's changes

slender iron

nope! happy to have it in @ruby atlas. thanks! I think the next step is getting the python version in the bundle

#

choir time for me, ttyl

pastel panther
#

@gusty topaz For $1.25 more you get a RTC with battery backup with the wing; seems like a no-brainer to me

@tulip sleet the Adafruit_CircuitPython_BLE release mentions a Location beacon example, but it tis not in the repo.

tulip sleet
#

that's a mistake, I should add one; maybe i should just use yorus

solar whale
#

Feel free

tulip sleet
#

@solar whale where does it say there's a beacon example? just want to make sure the filename is right, etc.

solar whale
#

in the release notes

tulip sleet
#

that's just a list of capabilities, not examples, but I agree an example would be good. I was a little reluctant to impersonate an iBeacon, but there are almost no apps that understand other company codes

solar whale
#

sorry --I misunderstood -- no problem - I understand

tulip sleet
#

did you try another company code with that app?

#

oh, that's the same app I ahve, well 0xffff didnt' work

solar whale
#

If I recall correctly, it dd not work until I used the Apple code, but I'll test it again tomorrow.

#

right -- that is what I tried.

tulip sleet
#

ok, no reason to try agian. Maybe I'll just publish with the Apple company code. or I'll ask the higher ups

solar whale
#

OK -- no rush to put it in , but it is a nice demo.

#

bed time here -- thanks for all the updates -- looking forward to playing with it tomorrow...๐Ÿ’ค

#

I can't tell if it's a problem in the descriptor or in the data that's being sent

tulip sleet
#

my guess is a descriptor error, like a bad length somewhere or something like that. I searched our DM history but didn't find "110"

#

@tough flax in that snippet, the first USB transaction that's being attempted (the host kernel asking the device for its device descriptor) is timing out

#

dunno if my commentary is too late to be helpful, but given the first transaction is failing entirely, I'd suspect the device isn't properly responding to anything USB

@tulip sleet is the latest build working for your demo?

tulip sleet

yes - jerryn found some issues with the doc and he can't get the uart echo to work, but the bluefruit connect demo works for me

#

i'm working on a demo for S&T

i think so, we can ship a beta.1 soon enough

solar whale
#

@tulip sleet do you use a crickit featherwing and feather_nr52840 for the bluefruit connect demo?

tulip sleet
#

yes

solar whale
#

ok - I'll try that in a bit. also updating my iPhone -- see if that helps

tulip sleet

i will test it again too. I was testing the UART stuff just from the REPL, to/from the phone. But I had tried on an old phone running iOS 10 as well as an IOS 12.latest

@meager fog The latter is almost working... semi-random failures on the esp when talking to Adafruit IO

tulip sleet

UARTServer() no longer starts advertising automatically. Maybe the demo is wrong. Where is the demo code?

solar whale

looks fine -- the example uses .write(bytes[one_byte])) and it fails every thime

in the BLE repo examples folder

yeah, that example is wrong, because it doesn't start advertising. I need to fix that.

@meager fog Yeah, I can go back to that. Ran into a blocker but I think I found a way around it. It's largely done.

@umbral dagger not that leeky - we have ESP8266 breakouts, i'll make one for ESP32 ๐Ÿ˜‰

tulip sleet

@slender iron I added a few sentences to the release notes, describing bleio in a little more detail, mentioning the second library, and adding a warning about outdated docs in the Known Issues.

slender iron
#

ok, sounds good

#

the docs will update faster than we release

tulip sleet
#

@slender iron btw, I had tried some FUSE filesystems for S3, and they were all terrible: slow, awkward authentication, and bad defaults (leading to ridiculous file permissions). The aws s3 CLI is limited but it works

slender iron
#

kk, fine with me. trying to figure out credentials now

meager fog
#

@umbral dagger ok so, chekin your list - whatcha wanna wrap up next, the CPM?

tulip sleet
umbral dagger
#

@meager fog I'll focus on the bitbang SPI, then the CPM.

tulip sleet
#

I put the code above in echo.py, did import echo after a ctrl-D, then went to the app, saw "CIRCUITPY" appear, connected, went to UART section of app, and typed and sent the above.

umbral dagger
#

@meager fog Apart from the flakey 8266 behaviour, the rest of the environment sensor works.

tulip sleet
#

I am filtering on UART-only apps in the bluefruit app. It takes a second or two for it to appear.

solar whale
#

sigh... hmm-- It works on IOS 12.1 on my iPhone6 but not on IPhone 7 with latest IOS -- may be the iPhone 7.... but also have Android issues... OK -- don't worry about it --- I'll keep working on it.

#

works fine from the desktop app....

which desktop app are you using? "able"

#

?

I tried that and didn't get anywhere

#

is poking the release

solar whale
#

@tulip sleet the crickit controller demo works on the iPhone6 w IOS 12.1 but not with the Iphone7 on 12.1.3 ... ๐Ÿ˜ฆ but the demo works great

#

aslo I cannot get it to work with Andriod at all -- give an error that it can't initialize the uart on the android app.

tulip sleet
#

the new ipad will not even connect, it just hangs saying "connecting..." it's running 12.1.1

solar whale
#

ah -- the plot thickens ....

tulip sleet
#

I didn't expect such random behavior

#

from the same mfr

solar whale
#

very odd ...

#

but the bluefruit connect demo is very cool -- nice work!

tulip sleet
#

there may be some extra protocol negotiation some of the devices are doing that we are not expecting, but why ๐Ÿคท ? I'm getting a demo ready for S&T, so I'll do some more concentrated debugging later

solar whale
#

I have the Bluefruit Connect App source code and I have compiled it -- I can try connecting to it via XCode and see if it give any information -- it's not a simple process, will try when I have some time --- Good luck on S&T -- this can all wait.

Hello everyone ... I'm looking for help.
During updating FW (from CP_3.1.1 to CP_3.1.2) my ItsyBitsy_M0 got stuck. It happened when copying dirs LIB and EXAMPLE to SPIFlash ... I probably wanted to copy more data than the capacity of the SPIFlash.
In fact, only the bootloader works (BLINK from Arduino IDE works OK).
If I try to copy the CP into the ItsyBitsy_M0 it gets stuck again.
I have such a feeling that I need to erase SPIFlash.
I found a suitable tool for it ... Adafruit_SPIFlash (https://github.com/adafruit/Adafruit_SPIFlash/tree/master/examples), but this doesn't work for ItsyBitsy_M0.
Can someone help and tell me how to turn my ItsyBitsy_M0 to life again.

idle owl
#

@tulip sleet There's no flash eraser on the troubleshooting page for the ItsyBitsy M0 or M4.

#

@buoyant wigeon Can you get to the REPL at all?

buoyant wigeon
#

NO, no response from CP...

idle owl
#

Ok.

tulip sleet
#

i haven't made flash erasers for a while, limor has been making them

idle owl
#

@tulip sleet Hmm alright. I figured the Itsy M0 would have been from your time making them, that's why I asked you. Where are they kept other than the learn guide?

tulip sleet
#

i could make a cpy build that does an erase on boot

#

give me about five mins

idle owl
#

Ok.

#

@buoyant wigeon We're going to make you a special CircuitPython build to try to fix your issue.

#

@tulip sleet I was thinking maybe we had them on GitHub somewhere or something.

tulip sleet
#

we should

idle owl
#

Fair enough ๐Ÿ˜„

#

@buoyant wigeon What exactly to you mean by "gets stuck" with installing CircuitPython from the uf2?

buoyant wigeon
#

WOW... it would be nice, special erase tool...

idle owl
#

We have them for many boards, we simply don't have one for Itsy at the moment.

#

I'm hoping the build Dan creates for you will work because it depends on where you're "getting stuck" with the install whether it'll get to the point where it can erase. That's my concern.

#

I'm not sure it's really a question you can answer. Since the "where" is happening behind the scenes.

#

@tidal kiln Are you around?

tidal kiln
#

yep

buoyant wigeon
#

"gets stuck" ... = I copy CP into ItsyBitsy, the whole process seems OK, restart and CIRCUITPY drive doesn't appear...

idle owl
#

@buoyant wigeon That's promising. We'll see how it works.

tulip sleet
tidal kiln
#

hmmm. this again. we had discussion on this...current process works but is hacky..needed better solution...did we create an issue?

tulip sleet
#

there's a better solution in 4.0 - you can get into safe mode early

idle owl
#

@buoyant wigeon Try installing the uf2 Dan just linked.

tulip sleet
#

with a triple click (last click a bit delayed)

tidal kiln
#

ah. and then erase FS from there?

tulip sleet
#

when the RGB led is yellow (it stays that way for 700 ms)

#

yah

buoyant wigeon
#

@tulip sleet Thanks... I will try it and will be back...

idle owl
#

@buoyant wigeon Remember this build will delete everything from your board. So be careful with it in general so you don't accidentally load it when you did not intend to.

tulip sleet
#

@buoyant wigeon replace it with regular CPy when you are done.

idle owl
#

@tidal kiln May I ask a few questions about the PN532? I seem to remember you being the one who dealt with it on RPi...

tidal kiln
#

"Danger Erase" nice. would make for a good B side track maybe.

#

@idle owl sure. been a while. and i've got some work i want to get back to on it at some point.

idle owl
#

@tidal kiln I'm updating the guide for CPy and Py on RPi usage

#

And I'm confused about the wiring. The only wiring diagram uses SPI, but the CP example does not use SPI. It came with a little chip thingie and I'm not sure if I need it? etc. Confused.

tidal kiln
#

looking....

#

chip is a level shifter

#

you set mode with the jumpers

#

can do spi/i2c/uart

#

i wired it all up at some point when i did that refactor work

idle owl
#

hmm

#

I2C seems easiest? Where does the levelshifter come in?

tidal kiln
#

the board 3v only, so would need it if using with a 5v board

idle owl
#

which these are not.... correct?

buoyant wigeon
#

@tulip sleet @idle owl You are the best... SUCCESS... ItsyBitsy is BACK.... Thanks a lot, you are AWESOME!!!!

idle owl
#

@buoyant wigeon Great!

tidal kiln
#

๐Ÿค” hmmm...is there a 5v board in the CP line up....?? i don't think there is...

idle owl
#

I was referring to CP boards and RPi when I said "these"

tidal kiln
#

rpi is def 3v

idle owl
#

Should have been clearer.

#

Thank you

tidal kiln
#

all the m0/m4 stuff is 3v

#

pretty sure nrf is also

tulip sleet
#

yes, we have no 5v cpy boards

#

yes, we have no ๐ŸŒ

tidal kiln
#

so...yah...i think you're pretty safe not using that little chip

#

now...how did i figure out i2c wiring?

#

oh. it's on the silk. SDA/ SCL

#

@idle owl do you have pi?

idle owl
#

I do. But I wasn't planning to wire it up. I can though if I need to.

tidal kiln
#

you're working up fritzing diagrams?

idle owl
#

Yeah. For breakout and shield. I guess breakout on CP something and a Pi. Shield on Metro Mx

#

I'll need to have it hooked up to something for the guide but I typically go with CP for testing the examples.

tidal kiln
#

ok. should just be a matter of setting those two jumpers for mode - there's a decoder ring printed on the board

#

and then follow the silk labels on the pins

idle owl
#

Ok

tidal kiln
#

it'd be good to hook this up to a pi and verify with blinka

#

i'm not sure i did that last time

idle owl
#

I thought you did already?...

#

oh

#

ok

#

I'll get it sorted

tidal kiln
#

i can test the pi out if you want

idle owl
#

Brennen's been my goto for testing on the Pi so I don't have that sequence down yet, it's still a stilted process for me. I've only tested a couple of Pi hats.

#

That would be really great if you could

tidal kiln
#

i only have breakout, but that's all that matters for pi

idle owl
#

I'll try to do the fritzing and then send it to you

#

Correct

tidal kiln
#

let's go the other direction - let me re-verify what works on pi first, then can send you deets

idle owl
#

That makes a lot more sense. It is not how we were doing it previously for most of the boards though ๐Ÿ˜„

#

Thank you so much!

tidal kiln
#

on a scale of zebra to nebraska, how urgent is this?

idle owl
#

definitely zebra. Limor wants the guide updated this week.

#

(The date on it is today in Basecamp, but....)

tidal kiln
#

so more like watermelon level urgent, ok..let me get on it..

idle owl
#

Thank you!

#

@tidal kiln So... if I'm reading this right, this CircuitPython library for the PN532 can read/write data from/to a card?

tidal kiln
#

yep

#

you can encode the tags with custom info

#

and then read it back

#

they come with some default info, so you can read right away if you want

#

"info" = varies depending on standard, mifare, etc.

idle owl
#

right on, thanks

tidal kiln
idle owl
#

I saw that wiring photo and that's what started the confusion.

#

Thank you for explaining it

idle owl
#

@tidal kiln I hooked it up to a Feather and I'm getting RuntimeError: SDA or SCL needs a pull up

tidal kiln
#

hmmm. probably not on board.

idle owl
#

Also it looks like like the req_pin is included in the basic example.. but it's not hooked up for CircuitPython

#

though my code hasn't gotten that far. it's failing on the i2c instantiation with the pull up error.

#

so it needs to be connected to 3.3v?

tidal kiln
#

yah, you'll need to add external pull ups.

#

since those pins do different things, they couldn't be bolted on

#

yep, pull up to 3.3v

idle owl
#

with a resistor or simply a jumper?

tidal kiln
#

resistor

idle owl
#

what size

tidal kiln
#

two, one on each SCL / SDA

idle owl
#

right

#

what size resistor though?

tidal kiln
#

got some 10k?

idle owl
#

yes I do

tidal kiln
#

start there

idle owl
#

ok works now. Turns out it helps to have the power rail plugged into the 3.3v pin on the breakout and not the next non-existent pin over.

#

Reads the card that came with it and my chip. Neat

@slender iron I'll revise the release notes in the three places to add a warning that bleio is not working properly on some models of phones/tablets :(.

@tidal kiln Limor said that SPI is basically the only thing that works for RPi. That I need to show wiring diagrams for all 3 on Pi, but with HUGE WARNINGS not to use UART or I2C.

whew. that's the reality i'm seeing also. ๐Ÿ˜ƒ

i was reading scroll back, and she did most of the pi work, and that was the same general fun happening then

found the answer to my previous question:

Writing '1' to CTRLB.TXEN when the USART is disabled will set CTRLB.TXEN immediately. When the
USART is enabled, CTRLB.TXEN will be cleared, and SYNCBUSY.CTRLB will be set and remain set until
the transmitter is enabled. When the transmitter is enabled, CTRLB.TXEN will read back as '1'.

tidal kiln
#

example looks like it hasn't been updated for serial on rpi, so here's what i was doing:

# UART connection
import serial
uart = serial.Serial("/dev/serial0", baudrate=115200, timeout=100)
pn532 = PN532_UART(uart, debug=False)
idle owl

I don't think I'm showing the code for it even

I guess it should go in the example?..

if we're saying don't do it, eh

@pastel panther did you start the wroom samd51 module yet? I might take a crack at it

pastel panther
#

@slender iron I did not

slender iron
#

kk, I'm shooting to have some fun stuff for pycascades and pycon

pastel panther
#

one thought that I had is to include the patch pcb to replace the CP2104 as a "peninsula" of sorts sticking off the top or bottom with mousebites since it's smaller than OSH Park's minimum.

I was also thinking of moving to a 51J to make all the pins/castillations functional

I kinda like the usb on the module

for designs that are missing usb completely

[adafruit/circuitpython] Pull request opened: #1491 support BLE\_GAP\_EVT\_DATA\_LENGTH\_UPDATE\_REQUEST, sent by newer devices

Newer BLE devices may ask to lengthen the basic BLE packet size. This request was not being handled, and so the connection attempt from a central to CircuitPython Peripheral was hanging. Respond in the correct way to this request.

@jerryneedell This I believe will fix https://github.com/adafruit/Adafruit_CircuitPython_BLE/issues/2. I tested on a 2018 iPad. Didn't test on an Android device, but thanks for testing if you are able to do so.

@solar whale I think I have a fix for the iPhone 7 problem. ^^. UARTServer now works on a 2018 iPad.

@tulip sleet Crickit demo also connects, but no response -- on Android

Andriod message "Uart protocol can not be initialized"

tulip sleet

probably something else similar to the above. What version of Android are you using?

solar whale
#

I've tried 2 -- one is 7.1.1 -- checking the other

#

its older 5.something

#

same problem on older one

Still -- great that you got the newer iPhone/IPad working!

The Adnroid does connect -- and the App closes when it disconnects, It just can't get its Uart protocol to work.

@solar whale if you uncomment the mp_printf at line 280 in ports/nrf/common-hal/bleio/Peripheral.c, that will print out the opcodes of all the unhandled BLE events. It's fine that some aren't handled, but there may be one that I need to handle. Then try the UART on Android and give me what shows up in the REPL. Maybe also do the exact same thing from the iPhone so I can compare the two. Thanks!

Guys, I need a little help here. I'm going through the example for the GPS FeatherWing (CP) and when running code.py, it gives me an error: TypeError: unsupported types for : 'int', 'str' The line referenced on the Traceback reads: gps.send_command('PMTK314,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0')

#

(it's the example line from the learning page).

tulip sleet
#

@solar whale yes! looking it up; I may need more info, not sure yet

solar whale
#

@gusty topaz If you are using CP4 then try gps.send_command(bytes('PMTK314,0,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0','utf-8'))

#

also make sure you set the uart timeout in seconds, not milliseconds

#

the UART API changed

gusty topaz
#

I'm using CP3

solar whale
#

hmmm -- nevermind -- not sure what's up then.

tulip sleet
#

@gusty topaz what line is the error on, and could you give the URL of the sampel code?

gusty topaz
#

Sure...

solar whale
#

@tulip sleet does the GPS lib handle both UART API versions? I had to change that llne in my gps program.

tulip sleet
#

no, prob not, prob there should be an issue

gusty topaz
tulip sleet
#

at least I don't think so -- I don't remember someone fixing that.

gusty topaz
#

Line 31 of the example code (CP Library section).

tulip sleet
#

and show the complete error with all the lines

#

that are printed out

#

@solar whale add this new case before the default right where you uncommented the mp_printf:

    case BLE_GATTS_EVT_SYS_ATTR_MISSING:
        sd_ble_gatts_sys_attr_set(self->conn_handle, NULL, 0, 0);
        break;

    default:
        // For debugging.

        break;
    }

ok

not sure if that's right. I need to go charge up my Android devices.

@tulip sleet Woohoo!! it works !! Well done!

@solar whale @SoutherDragon it does look like the UART code was changed to use bytes() instead of strings.
@gusty topaz trying changing line 31 to:

@modest atlas the brightness code will need to be inside the while True: loop. also, you'll need to adjust the voltage math. brightness is a float, with the range of 0-1.

it's a little klunkly, cause you have to type everything in

#

but it's more hand on, so kind helps get a better feel for things

#

hold on sec, let me come up with first set of commands....

modest atlas
#

perfect

tidal kiln
# 
Adafruit CircuitPython 3.1.2 on 2019-01-07; Adafruit CircuitPlayground Express with samd21g18
>>> import board
>>> import neopixel
>>> pixels = neopixel.NeoPixel(board.NEOPIXEL, 10)
>>> pixels.fill(0x112233)
>>>
#

that should get you some blueish neopixels

manic glacierBOT
modest atlas
#

yep

#

tealish blue

tidal kiln
#

if you don't like the hex value for color, you can also you (r,g,b) style

modest atlas
#

works for me

tidal kiln
#

like this:

>>> pixels.fill((50,10,30))
#

color should change right away

#

the values range from 0 to 255

modest atlas
#

sure did magenta

tidal kiln
#

ok, now brightness

>>> pixels.brightness = 0
#

should turn them off

modest atlas
#

off

tidal kiln
#

try other values between 0 and 1

modest atlas
# 
>>> pixels.brightness = 0.1
#

both work

tidal kiln
#

so that's the general idea for the neopixels, how you change color and brightness

#

want to move to reading the pot?

modest atlas
#

yes sir

tidal kiln
#

you're making a voltage divider with the pot? 3 wires, one to gnd, one to 3v, one to A6?

modest atlas
#

yes sir

tidal kiln
# 
>>> from analogio import AnalogIn
>>> pot = AnalogIn(board.A6)
>>> pot.value
21680
modest atlas
#

yep

tidal kiln
#

turn the pot, read again, value changes?

# 
>>> pot.value
32752
>>> pot.value
13744
>>> pot.value
8608
>>> pot.value
13024
>>> pot.value
64
modest atlas
#

yes sir

tidal kiln
#

cool. now we just need to tie this together.

#

pot.value will range from near 0 to near 65535

#

and pixels.brightness wants a value from 0 to 1

#

in this case, we can just divide to get there, but let's use something, so you can see it and know how it works - it will be useful for other stuff

#

it's called map_range - it's like map in arduino if you've done that

modest atlas
#

heard of

manic glacierBOT
tidal kiln
# 
>>> from simpleio import map_range
>>> map_range(pot.value, 0, 65535, 0, 1)
0.780529
modest atlas
#

that's works aswell

tidal kiln
#

turn pot, read again, and value changes...

>>> map_range(pot.value, 0, 65535, 0, 1)
0.997085
>>> map_range(pot.value, 0, 65535, 0, 1)
0.994156
>>> map_range(pot.value, 0, 65535, 0, 1)
0.963393
>>> map_range(pot.value, 0, 65535, 0, 1)
0.757092
>>> map_range(pot.value, 0, 65535, 0, 1)
0.485603
>>> map_range(pot.value, 0, 65535, 0, 1)
0.136965
>>> map_range(pot.value, 0, 65535, 0, 1)
0.0021973
modest atlas
#

yep

# 
0.999771
>>> map_range(pot.value, 0, 65535, 0, 1)
0.000488289```
tidal kiln
#

yep. so finally the magic you were after:

>>> pixels.brightness = map_range(pot.value, 0, 65535, 0, 1)
modest atlas
#

that's works

tidal kiln
#

turn pot, run that again, brightness changes?

modest atlas
#

not live but if I fresh

tidal kiln
#

yep. only when you run the command.

modest atlas
#

that's working

tidal kiln
#

that's all there is to the nuts and bolts

#

to make it "live" is just a matter of putting it in a loop

#

so you don't have to keep typing the command

manic glacierBOT
tidal kiln
# 
>>> while True:
...     pixels.brightness = map_range(pot.value, 0, 65535, 0, 1)
...
#

typing in loops like that can be a little tricky in REPL

#

after the first line, it should give you the ...

#

and then you can type the second line

#

when you get the second ... hit backspace and enter

modest atlas
#

wha-la its working

#

bravo

#

oh nice! what a great leason

#

thank you so much fir all your time

tidal kiln
#

np

#

that one liner hides a lot of magic

modest atlas
#

thags wy I kove circuitpython

#

that's why I love

tidal kiln
#

this is functionally equivalent, but shows more of what is going on:

>>> while True:
...     pot_position = pot.value
...     brightness = map_range(pot_position, 0, 65535, 0, 1)
...     pixels.brightness = brightness
...
#

you read the pot value

#

do some math

#

and set the brightness

#

ok...your turn...see if you can put all that into a .py file

modest atlas
#

ill do that now

# 
import neopixel
from analogio import AnalogIn
from simpleio import map_range

pixels = neopixel.NeoPixel(board.NEOPIXEL, 10)
pixels.fill((0,0,0))

pixels.brightness = 0

pot = AnalogIn(board.A6)

while True:
    pixels.fill((255,0,0))
    pixels.brightness = map_range(pot.value, 0, 65535, 0, 1)```
#

that worked!

#

that feels good

tidal kiln
#

@raven canopy sry for butting in

modest atlas
#

this is one amazing community

raven canopy
#

@tidal kiln ๐Ÿ˜‰ didn't take it that way, at all. like @modest atlas just mentioned...its a community!

tidal kiln
#

hope you didn't dig up a pot for no reason ๐Ÿ˜ฆ

raven canopy
#

hehe. i did, but it was acting super flakey. i don't even know what it was rated at. ๐Ÿ˜†

tidal kiln
#

1.21 gigawatts?

modest atlas
#

I'm using a cheap 19k metal pot

#

hahah

#

10k

raven canopy
#

might have been closer to 1.19. ๐Ÿคท

modest atlas
#

will the pixel.brightness class work with dotstart as well

tidal kiln
#

you would use a different library for dotstars

modest atlas
#

yes sir

tidal kiln
#

but it has a brightness setting as well

modest atlas
#

how do I check what setting they have

tidal kiln
#

so once you've done the import and created the dotstar object, it would look very similar

modest atlas
#

like the .show or .fill .brightness

tidal kiln
modest atlas
#

dang I have so so sooooo many questions will save them all for later but it never ends fr me

tidal kiln
modest atlas
#

i have a nRF52840 here i cant wait to play with

tawny creek
#

greetings all! I have a custom NRF52840 board that I was able to flash a bootloader on but cannot see "NRFBOOT", I can see the neopixel (blue) and the status LED blink, I can also press and hold the reset button and see the adaDFU appear on the iOS bluetooth app and I am able to connect to the module.

what are some ways I can debug and make progress so I can load up CP firmware?

manic glacierBOT
tulip sleet
#

@tawny creek which bootloader did you flash? And check your pin assignments against the ones given for pca10056 or pca10059 or feather52840 to make sure the bootloader's idea of the pins (especially the USB pins) matches how you did the board.

#

@tidal kiln When I get these Pi fritzez done can I send you screenshots to eyeball?

tidal kiln
#

sure

idle owl
#

Thanks.

tidal kiln
#

did you figure out the BCM numbering?

idle owl
#

I thought it was eq to GPIO numbers?

tidal kiln
#

yep. but for figuring out where they are on the fritzing part?

idle owl
#

you can highlight over the pin sometimes, it's not working right now, but I have a little PCB guide thingie here with all the pinouts silked on it.

#

Usually you can highlight over the correct part of the pin and it tells you what it is. But it's being rude at the moment.

tidal kiln
idle owl
#

but yah I've seen that link too

tidal kiln
#

those are BCM

#

i think you can just ignore any comments about BCM, everything seems to be using it - that thing, CP, etc

#

6 = 6

idle owl
#

I'd never seen that acronym is all. GPIO or D is what I've seen.

#

Blinka responds to D6 etc

tidal kiln
#

just confusing pin reference fun

idle owl
#

fair enough

tidal kiln
#

BCM ~= "broadcom"

idle owl
#

ahhh

#

ok

tidal kiln
#

confusion mainly comes from when people say something like "attach to pin 6"

#

6 = D6, BCM6, wiring pi 6, physical pin 6 on RPi header, physical pin 6 on broadcom chip, pad 6??? etc.

#

this is much less an issue in CP land, since the board labels and CP all agree

manic glacierBOT

#

@tulip sleet Thank you it was the Adafruit_nRF52_Bootloader! Where is the USB pin defined? I'm using the USB+ and USB- as labeled on the module

tulip sleet
#

@tawny creek oh, you're using a module! Also I see that the USB pins are dedicated. Are you double-clicking and you don't see the BOOT drive?

tawny creek
#

I dont ๐Ÿ˜ฆ

tulip sleet
#

what board is this?

tawny creek
slender iron
#

@tawny creek I think the bootloader checks a pin's value at startup to know the mode

tawny creek
#

I've set up P1.06 as Button 2, and the only reset pin available as Button 1

slender iron
#

is it pulled high?

#

button 2

tawny creek
#

Does these line #define BUTTON_PULL NRF_GPIO_PIN_PULLUP pull both of them up?

slender iron
#

I have no idea

#

that's what the colors mean

tawny creek
#

yeah i think im in that state by default even though im not connected via bt

tulip sleet
#

@slender iron @solar whale Just FYI, I'm debugging an issue where BLE code is failing when the board is not connected to USB, but is fine when it is connected. It appears to be inside UUID(). This may be an issue of the softdevice not be initialized properly if USB is not connected. (I was trying to take a movie of CircusPython with power but not USB connected, just due to cable length).

#

the UUID() call is the first softdevice call it has to do.

slender iron
#

@tawny creek that startup mode is based on the button and not BLE

solar whale
#

@tulip sleet Thanks for the heads up -- One thought, check to make sure your crickit is powering up normally. I keep forgetting to reset the crickit when I load firmware to the feather. The crickit stays in bootlaoder mode.. probably not related, but something I have gotten caught by a few times.

#

I should have some time to play with it this evening and tomorrow.

tawny creek
#

@slender iron ah ok the case title confused me

manic glacierBOT
tulip sleet
#

@slender iron tud_cdc_write_flush() and other usb operations are being called even though there is no USB cable attached. This seems to be from supervisor/shared/usb.c:usb_init(), which sets _usb_enabled even when it's not connected. Should there be some other kind of check about whether USB is really in use or not?

#

maybe usb_enabled() should be calling serial_connected() instead of just checking _usb_enabled

slender iron
#

my brain is in display land at the moment

#

I do want to rework cdc to flush automatically

tulip sleet
#

i'm seeing hangs even before it gets to the softdevice code, so I think maybe we haven't really tested 4.0 disconnected from USB yet, though I'm surprised it hasn't come up.

#

ok, I'll keep looking and will circle back if i get stuck

slender iron
#

kk, sorry. I can help tomorrow

#

hopin to do all the text/error stuff today

solar whale
#

@tulip sleet I have been running an argon off USB for a long time with 4.0

#

not using BLE

tulip sleet
#

thanks, that's a relief, didn't make sense to me it didn't work. I'm trying to track this down. it's not failing where I expect it to fail. Theory above about unitialized softdevice is not true, that's not the problem. but I'm getting there.

solar whale
#

last buid on that argon was from Jan 16 -- I'll update to Beta 0 and make sure it still runs

#

yup - current master is running w/o USB

solar whale
#

@tulip sleet I tried connectiing to the crickit demo (running as code.py) then unplugged USB and it continued to work, but on power cycle I the feather_nrf52840 neopixel is blinking green (maybe orange) the 5 blues -- is that what you see?

tulip sleet
#

yep, that's exactly the symptom. The issue is that enabling the softdevice is failing because it's saying there's an interrupt in use that is reserved by the softdevice. Am trying to track this down.

#

i have a heck of a time with those colors. I originally connected up a UART cable to TX/RX and wrote stuff to the UART to see where it was actually failing.

solar whale
#

ok -- must be orange then 5 cyans -- means it failing on the import UARTServer line with OSError

#

Let me know if I can be of any help.

tulip sleet
#

It appears it actually is failing on the UARTServer() call; I think the line number is inside that code rather than in main.py. That call creates some UUID()'s, and the first of those tries to enable the softdevice, and fails.

#

actually no, I take that back, it's the import, which creates some class variables by calling UUID(...), and those are failing

solar whale
tulip sleet
#

line 53 is returning a non-NRF_SUCCESS error code; that's where it has issues. I am on the trail of some other stuff. The usb initialization is assuming there's no softdevice (incorrectly). The fact that it works appears to be an accident.

#

that is, #define SOFTDEVICE_PRESENT was not actually set anywhere, even though it's critical. I think we should enable the softdevice much earlier than we are.

@tidal kiln heya i dont understand this PR

#

they're not using i2c-gpio right?

#

On todays Python on hardware video, there was a brief mention of a RISC-V board. I managed to find what I think was the referenced article on Robot Zero One. Looks like it was MicroPython-focused.

#

Has anyone looked at CIrcuitPython for other RISC-V chips?

#

SiFive?

tough flax
#

@meager fog I think I'm asking for more than I need ๐Ÿ˜ƒ I am trying to use one of these https://www.adafruit.com/product/3103 with the touchpad board as a breakout... I think all I really need is to know how X+, Y+, X-, Y- map to GND, 3V, X, Y

PSP 3000 2-Axis Analog Thumb Joystick

Sometimes a simple analog control device can be the perfect tactile solution for your project, but they can be surprisingly hard to come by. Luckily we've found a low cost, qualityย PSP ...

#

And I can probably figure that out with a multimeter in a pinch ๐Ÿ˜ƒ

tidal kiln
tough flax
#

Ha! Sweet

#

I'll figure out X and Y thank you!

tidal kiln
#

you're basically using that touch screen thing as a simple breakout

#

but its silk is for touchscreen use

#

so use that ^^^ pin out and it makes more sense what's being shown with that metro wiring

tough flax
#

Gotcha - thanks

manic glacierBOT

#

@tidal kiln yeah slow down i2c a lot and itll work

#

ive had it running for a couple hours

tidal kiln
#

cool

#

so, yah, consider that other issue a general request for sw i2c support via that overlay

#

i tried that out a while back with the BNO, and it also seemed to work fine

so, options.

true - i think long term yeah it would be nice to have. but its a nice to have ๐Ÿ˜ƒ

@tough flax wow, great! was just adding a delay the fix from a few days ago (or much more since then)?

tough flax

Yes! I realized it in the shower (go figure)... only thing it could be was a timing issue. We should probably see if there's a way Gamepad's constructor could wait to return until it knew it was good?

raven canopy
#

@tough flax awesome work! that last shot was a good one. ๐Ÿš€ โšฝ

#

@tough flax are you going to put some sensitivity/trim adjustment on it? or does the XAC already have that available? (haven't looked at the XAC yet, really)

tough flax
#

So...

#

๐Ÿ˜ƒ

#

I have a problem for math folks

#

I used to be a math folk

#

But I'm old and my Trig brain cells died

raven canopy
#

hehe. mine never gestated...

tough flax
#

The way I do the mapping, I end up with a circle that I can reach. I can reach full forward, full left, full right, and full back

#

but I can't hit the corners

#

I need a way to map that circle onto the square it inscribes ๐Ÿ˜ƒ

#

I believe it's a projection (like a map)

#

but I don't remember how to do them. Something like take the arctangent of the Y/X and then scale by the sin/cos of 1/2 the angle?

#

Right now, I just multiply by 2 and clip ๐Ÿ˜ƒ

#

So the center is much less sensitive than the edges

#

Anyway... the XAC DOES have sensitivity and even mapping options

#

and you can change them on each profile

#

So... there's lots of options

raven canopy
#

nice! glad they thought of that on the XAC. wrt the math...i have nothing to offer. ๐Ÿ˜ฆ

tough flax
#

@tulip sleet I'm not sure that's it - it seems that if the gamepad is setup too early, Linux and the XAC never really recover. Like the host isn't ready and just writes off the peripheral

tulip sleet
#

so even trying too early is a mistake, it has to be good and ready

tough flax
#

Yes, I was hoping there was a way to tell if it was ready - maybe in the USB stack

Hello. I apologize if this is answered somewhere else. I know there are ways to increase the adc sample rate in Arduino. Using circuit python, what is the standard sample rate for the m4 boards (I have an itsy bitsy) and what can that be reliably increased to? I understand that's probably a vague question.

@slender iron - thanks for the feedback on the SiFive boards. I have one of the first boards, as well. Just curious about it after Phillip's reference yesterday. Is there a good reference for minimum specs to support CircuitPython? Apologize if that's already posted somewhere obvious. Chalk it up to being new around here...

old smelt
#

I spend most of my time focused on FPGA-based hardware. But I am fascinated with CircuitPython for micros and have a longer-term interest in Python for High Level Synthesis in FPGAs/ASICs. CP seems like a logical step along that progression. So, I'm trying to soak up what I can, when I can.

#

I'd love to play with FPGAs, but most of them use undocumented proprietary formats, and the tools provided by the vendors tend to be DOS-only, with a Linux version that's unusably buggy.

solar whale
#

@slender iron any idea about the time.struct_time issue? I'm trying to follow it, but not getting very far.

slender iron
#

@solar whale looking now

solar whale
#

thanks

marble hornet
#

@slender iron ti worked! i'd love to get started on the rect and round_rect wrapper etc

#

it**

#

i guess Ti works too, the calculators are great! but kidding aside: ifyou can point me to the method or doc i'll get started

slender iron
#

@solar whale should it be (kw_args != NULL && kw_args->used > 0)?

solar whale
#

ah -- looks good to me -- I

#

ll give it a try.

slender iron
#

I'll try it here too

solar whale
#

but not clear to me wha any of the tests fail now.

slender iron
#

ya, me neither

manic glacierBOT
slender iron
#

@solar whale kwargs isn't null

solar whale
#

ah -- why?

slender iron
#

ยฏ_(ใƒ„)_/ยฏ

#

but used is 0

#

so parens and && should fix

solar whale
#

building now

manic glacierBOT
solar whale
#

it works!

slender iron

>>>
>>> import time
>>> x = time.struct_time((0,0,0,0,0,0,0,0,0))
>>> x
struct_time(tm_year=0, tm_mon=0, tm_mday=0, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=0, tm_yday=0, tm_isdst=0)
>>>
#

and my gps code works as well!

#

is kw_args ever == NULL ?

slender iron
#

maybe not to struct time

#

but in other places it is

solar whale
#

ok -- thanks -- seems happy now -- works for pcf8523 and gps

lime trellis
#

hi all! are there any examples of a samd51 running crystalless? I can get it to boot into bootloader mode, but it doesn't like any UF2 that I'm passing it

slender iron
#

@lime trellis its always crystall-less afaik

lime trellis
#

hmmm then have you see a case where the BOOT drive mounts fine, but dragging over a UF2 just results in it rebooting back to BOOT?

slender iron
#

what board are you using?

lime trellis
#

custom board

slender iron
#

and what uf2 are you loading?

lime trellis
#

all ones I've built myself. But I've tried the ItsyBitsy M4 and Feather M4 firmware as well. same behavior

slender iron
#

I've had a similar issue on a board when the decoupling caps were too small

#

not sure it went back to BOOT though

stuck elbow
#

I could never get to work a bootloader I built myself, for some reason

lime trellis
#

I've built quite a few for other boards. they seem fine so far

#

I was thinking it might have to do with #define BOOT_USART_BUS_CLOCK_INDEX MCLK_APBAMASK_SERCOM0 in the board_config.h file for the uf2-samdx1 boards

@slender iron do you want to fold the time.struct_time fix into a PR you are working on or would you lime me to create one for it?

slender iron
#

@solar whale a small pr from you would be awesome.

#

mines gonna be big

solar whale
#

๐Ÿ˜‰ OK -- I have to go out for an hour or so -- will do it when I get back.

slender iron
#

k no rush

exotic pumice
#

@slender iron I thought you guys were using xosc32k

slender iron
#

I don't think so

#

by its been a while since I've looked

exotic pumice
#

ok, I wonder if that's part of my problem

#

I know you're not using usbcrm

Please help anybody... I have Arduino Zero with UF2 bootloader but no CPy in UF2 format... only BIN. How to flash this BIN into Arduino Zero???

exotic pumice
buoyant wigeon
#

@exotic pumice Many thanks... will try

pastel panther
buoyant wigeon
#

@pastel panther I am maybe blind... I see only mkzero...

pastel panther
#

ah my mistake, I thought they were the same

#

Where did you get the bin from?

buoyant wigeon
#

@pastel panther adafruit-circuitpython-arduino_zero-3.1.2.bin

pastel panther
#

@buoyant wigeon I'm not sure why a uf2 isn't being built for the arduino zero but I'd have to assume there is a good reason. @tulip sleet do you know?

buoyant wigeon
#

@pastel panther I didn't know uf2conv.py... I had some troubles with cmd line... but finally I was succesfull... THANKS for good advice

pastel panther
#

did you get it loaded?

idle owl
#

@solar whale I'm not sure why it isn't triggering a build.

solar whale
#

@idle owl hmm -- Travis hates me ๐Ÿ˜ฆ

idle owl
#

But I don't deal with circuitpython very often.... Could be there's something needed on your end to get it to trigger.

solar whale
#

not in the past

idle owl
#

How recent "not in the past" though? I thought there were fairly recent changes to how it builds.... though I'm basing this on seriously peripheral awareness... like from reading GitHub threads and that's it.

#

So I'm not the best person to troubleshoot this. Probably best to wait for Scott or Dan to have a moment.

solar whale
idle owl
#

That's... weird.

#

And leads me to believe there's definitely something off.

#

We migrated everything.

solar whale
#

apparently my fork is still on travis.org -- some of my repos have migrated.

#

some have not

idle owl
#

Hmm.

solar whale
#

but it is running the wrong build -- I'm confused...

#

now it just started the correct one....

idle owl
#

Travis is mysterious.

solar whale
#

i'll wait until it finishes and see if it magically appears in the adafruit repo

idle owl
#

when you wire something up the same way you did yesterday and now it doesn't work. ๐Ÿ˜–

[adafruit/circuitpython] New comment on pull request #1497: fix kw\_arg checking for time\.struct\_time\(\)

Hi, we enrolled in the Travis beta migration program: https://docs.travis-ci.com/user/migrate/open-source-on-travis-ci-com/#existing-open-source-repositories-on-travis-ciorg. Once we were in it, a list of repos we could migrate showed up on https://travis-ci.org/account/repositories at the bottom, if I remember right, with "Migrate" buttons. You can also just wait for them to migrate your repo eventually.
