@vague monolith - I foolisly tried to upload once as root - it failed, but may have created the dir name METROM4BOOT owned by root.
I did not think to look for it.
vague monolith
@solar whale why are you using a root account?
pastel panther
@errant grail where did you get your boards made?
solar whale
no - I was getting permission errors and tried using sudo.
errant grail
Express PCB for now. Need to move my component libraries to KiCad so that I can use other vendors.
vague monolith
@solar whale which distro are you using? perhaps your user doesn't have access to /dev/tts devices, but I came here late.
solar whale
@vague monolith - its all good now - I was just beeing foolish.
solar whale
Im not sure how I initially ended up with a "stale" METROM4BOOT folder, but once I did, I confounded it by using sudo and makeing it a real local folder owned by root. Once I deleted it, the problem was resolved.
I was using the command line to copy th .uf2 to /media/user/METROM4BOOT so if there was an problem it created the folder locally. Next time I entered bootloader, it used METROM4BOOT1 - and I got confused.

hey @solar whale I don't think I'm going to be able to get something to you till later tonight. Pulling in the 2x fixes didn't work so I have to hook up the jlink and poke some more, but I have to pick up dinner and hang with the fam before they leave town
@idle owl ow!

@pastel panther no problem - I'm off to bed anyway -I've done eough damage for tonight.

Be happy to try something when you have it

@vague monolith if you're experienced with udev, I have a query for you
vague monolith
@tulip sleet ?
tulip sleet
@vague monolith usually getting to the UF2 bootloader will cause the ...BOOT drive to appear in a file manager (nemo, nautilus) and be mounted. However, sometimes the drive appears but is not mounted, and so then it doesn't show up in /media/<username>/...BOOT. . It's a UF2 drive, so it's simulated, doesn't have a bad dirty bit, etc. So I have to click on it in the file manager and it mounts, and then I can copy to it. So why would it sometimes not auto-mount?
I've done some research on this and haven't come up with a reason.
sometimes the CIRCUITPY drive doesn't mount either. Is that due to a previous error associated with the USB device or the port. Switching ports or rebooting I think clears the problem, but I haven't tested systematically.
as an example, I'm seeing that right now with a Metro M0 board
vague monolith
When the drive appears and isn't mounted, does dmesg have output showing errors?
@tulip sleet
tulip sleet
hold on, collectin the syslog text for you
vague monolith
This all should be handled by some sort of udisk wrapper
It could be an issue with the wrapper
timber mango
He probably has more permissive automount foo. I don't .. never learned how to do that. So mine never (Ever) automount. I have to click on fooBOOT or CIRCUITPY to mount, in nautilus. Every time. Debian.
tulip sleet
trying to make it short enough to paste
vague monolith
@tulip sleet I did find a tool for exploring the dbus messages would help debug more than syslog

@timber mango main q is whether CIRCUITPY is mounted automatically (and same q for the ...BOOT drive for that board). It might not auto-mount if there are errors.
i.e. is it showing up in /media/<username>/<drive> or not?
but time for sleep now
BDMV is about Blu-Ray drives (??), so maybe you have some support for those enabled.
timber mango
Yeah CIRCUITPY never (ever) automounts on my Debian amd64 system. It's present, but I must click on it in nautilus (or use 'mount' at the command line) to mount it. When I do, I have the right permissions to write to it.
I tried (just now) installing 'usbmount' which mounted the target as /media/usb0 and required root permissions to modify main.py and friends.
Removal of the usbmount .deb restored the prior behavior (didn't cost me to give it a try).
goodnight Dan. ;)

hey @slender iron I think I found a bug with the itsy bitsy's hardware
it looks like the clock pin of the dotstar is wired to pin 1/PA00 which can't be used as a SCK because it can only mux to sercom 1 pad 0 and SCK has to be on pad 1 or 3 for the SAMD21
This just means that it has to be bitbanged; not the end of the world but đ¤ˇ
solar whale
@slender iron @tulip sleet so far buillt 3.0 master for itsybitsy_m0,trinket_m0,ESP8266, feather52840 and loaded onto boards - no problems other than known issue with dotstar on trinket_m0. minimal testing on esp8266, itsybitsy and tinket, just enteered REPL - tested dotstar on itsybitsy - tested i2c devices on M4 and feather52840 as well as SPI (SD Card) on feather52840 - no issues so far.
frail geode
I've got a Metro M4 unit here and I can't reprogram from Arduino without doubleclicking the reset button. Any ideas? Expected behavior? (and once again, if there's a better channel for SAMD51 non-python stuff, sorry!)
solar whale
@frail geode I have been experiencing the same problem recently. This had been fixed for awhile, but may have been broken again with recent changes to the USB handling in CP3.0
@frail geode just to clarify - if you have an arduino sketch loaded, can you reload a new on without double tap?
I think I only have this problem if I have CP running and want to go to Arduino.
If it happening all the time (that is with arduino already loaded) then check taht you have the latest samd51 support installed.
frail geode
I think it is happening all the time, even if an Arduino sketch is already loaded, but I need to confirm.
I installed samd51 support from the Adafruit samd repository maybe a week ago.
Let me confirm and I'll be back tomorrow!
solar whale
I'll also confirm that I can upload without double tap if arduino already loaded. I know I could do it awhile back but not sure if I was able to do that a few days ago when I ran into the issue when CP3.0 loaded. I don't think the tools have changed recently.
frail geode
Yeah, I am not sure if it ever worked without the doubletap either.
tulip sleet
@frail geode @solar whale could you file an issue?
if there isn't one already?
@pastel panther the itsy bitsy pin choice may have been deliberate to maximize the available SERCOMs
solar whale
@tulip sleet I'll file one this evening after I verify the behavior.
@tulip sleet what is teh impact of the itsybitsy pin concern @pastel panther raised?
tulip sleet
@solar whale it just means we have to do bitbang.SPI to control the DotStar. I think there might even be conditional code to do that already.
solar whale
But I was able to use the dotstar with CP3.0 Master as is
frail geode
Thanks jerryn
tulip sleet
@solar whale did you use busio.SPI? Then maybe @pastel panther drew an incorrect conclusion. I haven't looked at it yet.
solar whale
let me check
solar whale
@tulip sleet I just used this ```from board import *
import time
import adafruit_dotstar as dotstar
pixel = dotstar.DotStar(APA102_SCK, APA102_MOSI, 1, brightness=0.1)
#pixel.fill([1,1,1]) #fill is whole strip at once
pixel[0] = [0,0,255]
pixel.show()
time.sleep(60)
looks like it is using busio.SPI
def __init__(self, clock, data, n, brightness=1.0, auto_write=True):
self.spi = None
try:
self.spi = busio.SPI(clock, MOSI=data)
while not self.spi.try_lock():
that is in adafruit_dotstar.py
tulip sleet
self._spi = None
try:
self._spi = busio.SPI(clock, MOSI=data)
while not self._spi.try_lock():
pass
self._spi.configure(baudrate=4000000)
except ValueError:
self.dpin = digitalio.DigitalInOut(data)
self.cpin = digitalio.DigitalInOut(clock)
self.dpin.direction = digitalio.Direction.OUTPUT
self.cpin.direction = digitalio.Direction.OUTPUT
self.cpin.value = False
If ValueError (SPI not working), it falls back to GPIO (bitbang)
@pastel panther is correct about the pins, but we handle it with ease
tulip sleet
The Arduino library handles both, but you have to know about the pins, iit looks like. This is better.
solar whale
makes it all look like magic to the uninformed - like me đ
tulip sleet
well, I didn't know that off that bat -- had to read the code
pastel panther
@solar whale @tulip sleet That's interesting; I wouldn't have thought of that as an approach to save sercoms but it does seem like it would work, though it could be confusing (as it was to me)
@solar whale It looks like you're essentially taking control of the built in status dotstar. Is that an established use case? It sounds like it but I'm still trying to wrap my head around the code involved. I'm running into a case with my bitsy-ish m4 board now where I get an error if I try and use SPI on pins that share a sercom with the sercom that my dotstar is using, even if there is a spare sercom on the same pin. Like the check for if it's in use isn't working correctly.
solar whale
@pastel panther I was just playing with the built-in dotstar. Adding more confuison thatn help tp the discussion.
pastel panther
and now my CIRCUITPY is stuck read only
solar whale
are you on linux?
pastel panther
@solar whale No, not at all! The code for the status led and SPI is confusing so you letting me know about other valid code paths actually helps
no, OSX so similar but different
manic glacierBOT
solar whale
I often end up with drag.drop - read only, but can copy to the CIRCUTPY from command line. --- or else the FS is hosed and I have to wipe it!
pastel panther
for me it seemed to happen when I had CP stopped at a breakpoint, then continued again and tried to open a screen to the CDC
I'm going to reboot to see if that helps
ta dah!
well I can debug the code again but that doesn't mean I understand it!
đ¤Ś
it doesn't help that the variables I care about have been optimized out so I can't inspect them đ
solar whale
the compiler can be so helpful at times.
pastel panther
some times you have to be the CPU
though I think even the m0 has a much larger cache than me
solar whale
can you "outsmart" the compiler by declaring those varialbles as "volatile" so it won't optimze or cache them? jsut a thought...
pastel panther
I tried that previously to some success, though I think I know the problem, just have to verify it
smart idea though; I didn't know about that tactic until I read up on it a while back
solar whale
sometime it works - sometimes it changes the flow enough to hide the problem too...
pastel panther
hey @slender iron do you have a minute for a SPI/dotstar question?
@solar whale, maybe you know this
if i have a typed pointed (say Sercom* sercom) and a void pointer (say void* hw) do I have to cast the void pointer to the type of the other to compare them correctly?
đ
haha, that's the cricket emoji
silly commonwealth
solar whale
@pastel panther sorry - was away - I would just have to try it to be sure. Probalbly several times đ
pastel panther
my testing says "no, that's not going to help"
I give up for now! The salary man/salt mine calls
timber mango
@tulip sleet
$ pmount /dev/disk/by-label/CIRCUITPY
$ pumount /dev/disk/by-label/CIRCUITPY
I found that iterating pmount and pumount restore the automount behavior (but for me, only in GNOME; ordinarily I run an .xsession and few GNOME daemons).
Debian shipped out of the box with GNOME enabled; I disable in the simplest way I know: run an .xsession file (and fluxbox). So GNOME is still installed and chafing at the bit; I just don't unleash it.
pastel panther
hey @slender iron I'm looking at line 60 in SPI.c; current master has it like so:
potential_sercom != status_apa102.spi_master_instance.hw &&
``` which won't compile because `status_apa102` no longer has a `spi_master_instance` member.
I replaced it with
potential_sercom != status_apa102.spi_desc.dev.prvt &&
which seems correct based on the call later in `common_hal_busio_spi_construct` to `spi_m_sync_init` which sets `dev.prvt` to what was `sercom`
int32_t spi_m_sync_init(struct spi_m_sync_descriptor *spi, void *const hw)
{
int32_t rc = 0;
ASSERT(spi && hw);
spi->dev.prvt = (void *)hw;
<clipped for brevity>
slender iron
yup yup
pastel panther
The problem I'm getting is that line 60 should be seeing that potential_sercom is the sercom used by the dotstar and continuing but it isn't
pastel panther
I think maybe status_apa102 isn't refering to what I think it is? Maybe? That's the only thing I can think of at the moment
slender iron
@pastel panther hrm, have you tried using the debugger to see the values?
yeah, there is a lot of state to check there
pastel panther
refer to my previous comment about status_apa102 (or was it potential_sercom) being optimized out
slender iron
did you turn off lto?
pastel panther
?
slender iron
commenting this line can make it easier to debug: https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/Makefile#L99
pastel panther
ah, good to know. Does it change what gets optimized? The last time I tried optimization off it didn't fit anymore
I think I messed up with how I declared status_apa102; Previously I think it was brought in by including rgb_led_status.h that file is no longer included so to get it to compile I haphazardly/blindly called it extern busio_spi_obj_t status_apa102; which got it to compile but I'm thinking doesn't work
tulip sleet
I set variables to volatile, and sometimes do -fno-inline, without having to lower the optimization level.
pastel panther
I just included it as such and it compiled though I can't test it because I'm at work now.
#include "supervisor/shared/rgb_led_status.h"
unfortunately I haven't done any C since just before I dropped out to work so 50% or more of my coding is "does this compile?" "ok, now does it work"
I swear I kinda understand! I paid attention in class!

heady dove
I am having a heck of a time ....
I have been working on a Feather Huzzah 8266 board
My main machine is a Dell OptiPlex 755 running Ubuntu 16.04 LTS
I also have a Mac Mini as well
I had 2.2.3 installed
I continue to be able to communicate with the Huzzah via ampy
I had been having no issues getting a REPL via screen
recently (and I can't pinpoint a event where things changed) if I
screen /dev/ttyUSB1 --baud 115200 (ttyUSB1 is sometimes ttyUSB0, depending)
In response I get a blank "screen" screen, the only way out of which is pulling the USB cable
This happens on both my Ubuntu machine and my Mac Mini
After a chat with one of Discord's CP helpers one thought was to go back to 2.2.1 I have done that yet the problem persists.
In frustration I decided to work on a CPX project
(https://learn.adafruit.com/circuitplayground-minecraft-gesture-controller/overview)
I was able to screen into the device (screen /dev/ttyACM0 --baud 115200)
I also was able to inspect the 2.1M drive created by the CPX
I decided to just download the code and drop it into my CPX
Nothing seemed to happen, so I screened inagain and did a ctrl D, saw that I had neglected to add the libs required, I downloaded those and extracted them to the CPX
I rebooted the CPX
The 2.1M drive did NOT reappear, and I am unable to screen into the device
Any thoughts oh great collective mind?
tidal kiln
@heady dove was that on mac or ubuntu with the CPX?
heady dove
@tidal kiln I did it originally on teh Ubuntu machine, after I took it to the MAc and a drive never appeared there either
@tidal kiln I downloaded the newest .UF2 and reinstalled it, still no drive
tidal kiln
so it still gets into bootloader ok?
heady dove
@tidal kiln yes it does
tidal kiln
"I downloaded those and extracted them to the CPX" <-- describe how you did this more
heady dove
@tidal kiln clicked "newest release, cleck the appropreiate fle, after down load I opened it in Archive Manager, extracted directly to the CYPLAYBOOT
@tidal kiln should I not extract directly to the device?
@wait a minute
that doesn't make sense
tidal kiln
CPLAYBOOT or CIRCUITPY?
tidal kiln
that's the correct folder name, but you said CPLAYBOOT above
wait. sry.
CIRCUITPY
CPLAYBOOT is what you see when it's in bootloader mode
tidal kiln
you want to copy it to CIRCUITPY, not CPLAYBOOT
https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-libraries#installing-the-circuitpython-library-bundle
heady dove
I am refering to the Circuitplayground 2.2.3 UF2 file
I don't have a CIRCUITPY Drive.... thats what disappeared
I was attempting to go back to a"clean slate"
tidal kiln
sounds like the firmware. yes, that should go to CPLAYBOOT:
https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython
and you're right, it's not a zip file, you can just download the .uf2 directly
heady dove
@tidal kiln Yes I extracted the lib folder directly from Archieve Manager to the CIRCUITPY directory, which may have caused my problems
@tidal kiln I'm getting really good at messing these things up
tidal kiln
huh. weird that archive manager even opened it. but yah, that could've done it.
if you can get back to CPLAYBOOT, then you can just try again
just drag the UF2 file over
heady dove
@tidal kiln well the library bundle is a zip
that was what I extracted to the CIRCUITPY drive
tidal kiln
correct. that's a 2nd step. once you've got a functional firmware install.
heady dove
it had been working, when I not longer had a CIRCUITPY drive after installing the lib folder, that is when I attempted to reinstall the firmware
tidal kiln
ok. see if you can recover by simply dragging the UF2 over to CPLAYBOOT
(we'll worry about the library bundle next)
heady dove
@tidal kiln I have tried that twice so far
tidal kiln
filename = adafruit-circuitpython-circuitplayground_express-2.2.3.uf2 ?
heady dove
correct
tidal kiln
and you're doing this on ubuntu or mac at this point?
heady dove
just did it a thrird time, replete with another download
ubuntu
I can go try it on my Mac if you think I should
tidal kiln
nah. just wanted to make sure which one.
heady dove
the Mac is my "Music making machine"
tidal kiln
raven canopy
@heady dove sorry you're still having the issue. @tidal kiln is a master troubleshooter, so you're in good hands with him.
heady dove
@tidal kiln so the drive is back, Thanks for the link
@raven canopy No worries, He is very good, we have chatted in the past
tidal kiln
@heady dove sweet. now go back to bootloader mode and see if you can drag adafruit-circuitpython-circuitplayground_express-2.2.3.uf2 to CPLAYBOOT
(guess that's like step 7 of what i sent also)
heady dove
@tidal kilnDone! and I extracted the lib forlder to my desktop and copied it to the CIRCUITPY folder
tidal kiln
so all good now?
tidal kiln
i haven't done much (any) CP on the ESP8266
"In response I get a blank "screen" screen,"
heady dove
no worries, you saved the day on the CPX, nice to know about the erase uf2
tidal kiln
could there be a script running? did you try <CTRL>-<C>
heady dove
I rm'd everything but boot.py from the drive
but let me try it
No ctrl C does nothing
it's weird that ampy works fine at the same baud rate, but screen just freezes
everyonce in a while and more often on the Mac, I get non displayable characters like it is a baud rate issue
and if I webrepl in I get a REPL prompt, but it seems to randomly generate ~N~M~r characters
tidal kiln
hmm. not sure on that issue.
tidal kiln
there are better esp8266 ninjas here than me
slender iron
@heady dove did you type characters into the screen session?
heady dove
I type, but nothing displays
slender iron
hrm
heady dove
ctrl C doesn't interupt, it's "frozen"
slender iron
its just blank right?
heady dove
the only thing I can do is pull the USB cable which returns me to the commandline prompt
yes
heady dove
that did indeed work
just tested it, I couldn't remember that command, though I knew it existed
slender iron
hrm, I've had it work after erasing and flashing
heady dove
it's weird, I can use both ampy and esptools, they all seem to work fine
slender iron
ampy works?
heady dove
yes
slender iron
but screen doesn't?
heady dove
correct
heady dove
I thinks, but I can try right now
slender iron
its possible ampy left the serial in a state that doesn't echo anything back
heady dove
so I just did a ampy ls ... it returned boot.py
now I'll do a reset
when I screened in
��FÜďż˝L
was the resonse
response

what was your screen command? garbage can occur when the baudrate is wrong
heady dove
and the screen is "frozen"
I hit return
screen /dev/ttyUSB1 --baud 115200
was what I typed at the command line
heady dove
ubuntu
slender iron
ah
heady dove
lol
I have access to and have tried on my Mac
same results
I don'y have a Windoes machine
heady dove
yes, sometimes it is ttyUSB0 depends
I typically ls the dev directory to see prior to ..
okay
holy moly!
slender iron
that work?
heady dove
sure did
slender iron
sweet!
heady dove
when did I start adding that ... hmm shooting myself in the foot again đ
why do I hit my head against a brick wall ......
cause it feels so good when I stop
Thank you Sir!
can I ask one more question?
slender iron
yup!
heady dove
If I want to send data from an sensor over the wifi , how do I format the command
I'm using the lsm303 library
slender iron
thats a complicated question I don't have a good answer for
heady dove
okay can you point me at something to read?
raven canopy
@heady dove glad you're up and running again!
as far as sending info...where are you sending it to?
(note: my esp wifi experience is mostly Arduino...)
heady dove
a friend wants to send movement data to Ableton Live via Max for Live
I believe he said something about JSON ...?
which I think is some Java type thing..
he's going to open a socket and process the data
raven canopy
JSON is just a format, like XML. (though i think it did originate in the Java world)
which type of socket: TCP/IP or UDP?
heady dove
okay, I'm brand new to wifi and web stuff as far as ucontrollers is concerned
TCP/IP I imagine
but it hasn't been implimented yet, I'm newly unemployed and just started working on the project again after a year offf
slender iron
I think @solar whale has managed to do it but I don't know of any good tutorials
I think we'll do a proper polish job on wifi support with version 4 or 5 of circuitpython
heady dove
@slender iron Is it really that dificult to print data to the wifi port?
raven canopy
ok. like i said, my esp wifi experience is in Arduino, so all I can really do is send you to the information you'll need. circuitpython docs don't cover much any of the wifi, since micropython does all/most of the dev. I would start here: http://docs.micropython.org/en/latest/esp8266/esp8266/tutorial/network_basics.html#
slender iron
yes
raven canopy
@slender iron all of micropython's wifi function is still in our build, isn't it?
slender iron
yeah, I think so
but I haven't looked at it
@heady dove I'd like to make it simple đ
raven canopy
me neither. yet. đ
slender iron
(the bot doesn't like lots of x)
heady dove
I was wondering what the heck that waas
raven canopy
dyno is very PG...
heady dove
dyno?
raven canopy
@heady dove for your side of the wifi, ignore the AP stuff. STA is short for station, which is the client side.
?whois dyno
digital shoreBOT
Dyno#3861
raven canopy
dyno is "The one and only..." đ
heady dove
wow, who knew
okay, so there isn't a explicit "port" to send data to, that goes over the wifi
raven canopy
nope. it just sends it over the broadcast. you'll need to use the socket library to send data to an IP
heady dove
so create a socket and send it to a IP
and format it as JSON, if that is what my buddy wants
I will investigate, thank you both so much, for getting me back on track
slender iron
đ
heady dove
I think I shoulld go make dinner đ
raven canopy
yeah. i'm looking at circuitptyhon's esp8266 port...socket may be missing. i'll do some more digging, but you may end having to use mircopython instead. i'll ping you when i get a handle on it.
heady dove
I thought I used it, maybe not
raven canopy
also, micropython has a JSON module that could do the formatting for you (it isn't hard to do manually in small bits though)
heady dove
I'm working on three different platforms concurrently
raven canopy
haha. good times.
heady dove
well I am in way over my head, but I, sadly, have lots of time on my hands
so I muddle along, and I say it almost every time, this community is absolutely awesome
thanks again, you can be certain, I'll be back with more questions
raven canopy
we'll be here

solar whale
@frail geode @tulip sleet created issue for arduino upload to m4 - Note: I can repeatedly upload arduino sketches without manually entering bootloader. The only problem is if CP3.0 loaded then arduino sketch load fails as shown in the issue unless I manually enter the bootlaoder.
raven canopy
@heady dove found socket in circuitpython...you should be good to go. and of course jerryn shows up after you leave... đ
slender iron
@solar whale its likely that the 1200 baud baudrate detection is broken
solar whale
ah - ok - just wanted to get the issue documented.
slender iron
thanks!
raven canopy
he is once again interacting with REPL.
solar whale
OK - will wait until more questions are asked. I'm no expert on it. I can post to an adaftuit.io feed and that is it.

and with that GitHub novel...i think i'm taking the rest of the night off. but, i've said that before... đ
pastel panther
@slender iron Have you ever ran into trouble setting breakpoints and resetting after adjusting the -flto and -fno-inline flags?
pastel panther
Previously I had no problem setting breakpoints in SPI.c for the duplicate sercom checks but when I commented out -flto it would set two breakpoints, presumably because it found two SPI.c files; I got more specific about the fie path and it seemed to find it but it wouldn't hit the breakpoint after resetting.
for example I tried
(gdb) break SPI.c:65
Breakpoint 1 at 0x25324: SPI.c:65. (2 locations)
``` and like it said it found two locations:
(gdb) info break
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x00025324 in common_hal_busio_spi_construct
at common-hal/busio/SPI.c:65
1.2 y 0x00027b42 in bitbangio_spi_make_new
at ../../shared-bindings/bitbangio/SPI.c:65
yea, my m4 board
pastel panther
ok, thats usefu
+l
is monitor reset the expected way to start over from the top?
slender iron
yeah I do it that way
pastel panther
that's what I've been using but I get the feeling sometimes it doesn't work
I saw that you can monitor reset 2 to use the reset pin to reset if you hooked it up but I don't know that it was successful
welp, I just read your gdb article again and answered a question I've had for a while regarding why I can't see variables. Wrong frame!
slender iron
info locals is helpful too
pastel panther
is 0x0 null/unset?
pastel panther
hmm... i set an asm("bkpt"); and now I can't see to continue past it
slender iron
I usually just read the local state and then reset
I don't think I continue past it often
pastel panther
hmm.. maybe I'll have to rethink this. I'm trying to catch the state where my code.py tries to set up a spi object on a pin that can map to the sercom my dotstar is using (but obv shouldn't)
slender iron
you can always put an if around the bkpt
pastel panther

@slender iron Data point for you: built 3.0.0 alpha 1 yesterday afternoon, and have been starting to test sensors on the M4. CCS811 and SGP30 both work flawlessly. (Board is Metro M4 Express.)
crystal pumice
hey, when playing with the lis3dh, i see the acceleration output is between -1 to 1, somebody here knows what is the output with the lsm303?
crystal pumice
cuz i see that in the digital sand the code is using data from the raw_acceleration function(from lsm303) and with the lis3dh ive got only acceleration function with a float number, which messing things afterwards
crystal pumice
i see now that in the lis3dh ive got in the acceleration function a calculation that: # convert from Gs to m / s ^ 2 and adjust for the range , if ill delete these section of code, u the the data will be same as the raw data from the lsm303?
proven kettle
Hello ! Anyone running Circuit python MU in Mac OSX ?
tidal kiln
@crystal pumice i think the lsm303 raw_accelerometer returns milli-Gs. it looks like the lis3dh only has acceleration which returns values in m/s^2. i wouldn't delete or modify the code from the library but instead do the conversion in your modified version of digital sand

pastel panther
hey @slender iron I was able to get a build last night that I could properly interrogate though I only had enough brains left to learn that I'm still confused by some of the conditionals đ¤
I should have enough brains left tonight. I'm so close
slender iron
đ
pastel panther
@proven kettle I have it installed but haven't used it much. Are you having an issue with it?
tidal kiln
@plucky flint nice!
pastel panther
ooh, thats nice
timber mango
@tulip sleet This does something similar to what's desired:
$ /bin/pwd; cat ./99-automount.rules
/etc/udev/rules.d
# --sync to allow removal without corruption
# exclude sda since its the rootfs
ACTION=="add",KERNEL=="sd[bcd]*", RUN+="/usr/bin/pmount --noatime --umask 000 %k"
ACTION=="remove", KERNEL=="sd[bcd]*", RUN+="/usr/bin/pumount %k"
I'm seeing more subtleties to this mounting of CIRCUITPY in Linux, than I would have looked into, otherwise. I don't understand quite what is going on.
Things work a bit more automatically (for CP volume automount) when in a GNOME session, but they're really not bad, when running GNOME piecemeal, such as a standalone nautilus (without the full GNOME environment).
Since I don't routinely want automounting of regular USB thumb drives (at all; I prefer to mount them manually) I'm probably already where I need to be, with this (unless I can very much target Adafruit-specific devices for automount).

@idle owl am now
idle owl
@tidal kiln I'm about to test the code for LSM303. But can I throw up a gist and have you look at it?
tidal kiln
sure
idle owl
Thanks
There's some linting changes, too, I'm not worried about those. I specifically want to make sure I understood the changes you were suggesting correctly.
tidal kiln
yah. seems good. change the two function names. convert list to tuple. that's about all i'd expect it to take.
or property names, or whatever they're suppose to be called in python
idle owl
methods technically I think. But yes đ
Ok keen thanks
I'll test all the examples with it and make sure it all works. Then put in the PR.
tidal kiln
and update readme example?
idle owl
Oh. Good call, I didn't even think about that.
tidal kiln
@solar whale doesn't do that for me on ubuntu, what're you running?
solar whale
Ubuntu
tidal kiln
how'd you get that output?
solar whale
Click on gear at lower right
tidal kiln
well. now it does.
solar whale
Cool! Youâre welcome đ
tidal kiln
just rm -rf the .cache and .local/share folders and restarted. doesn't create them on initial start.
doesn't create the image and sound folders
but does on second start
huh. maybe it's an easter egg?
idle owl
@tidal kiln Do you have merge capabilities on LSM303?
tidal kiln
prolly
idle owl
I'll add you as a reviewer, if you can and have a moment, that would be great.
tidal kiln
sure
solar whale
@tidal kiln just glad Iâm not alone!
idle owl
@raven canopy Where in the LIS3DH guide did you see the update needed?
Nevermind. It's within the text. I see it now.
raven canopy
yeah...its a few IIRC.
idle owl
I only found one.
It looks like all the code is code-elements, not embedded.
I need to read before I keep asking things. It's all within the text isn't it?
raven canopy
hehe. give me a sec. it's prob only one that needs to be updated, since we only changed one filename
idle owl
No, you're correct. I'm up to 3 now.
tidal kiln
@idle owl done. couple of tweaks.
idle owl
Should all be updated now. But if you could check it again, that would be amazing, since I'm clearly missing things.
raven canopy
that was quick. one of them was already changed, and threw me off. đ
idle owl
Refresh again to get the rest đ
raven canopy
@idle owl need to change the ampy --port /dev/serial/port run -n accel.py right below Accelerometer Usage
idle owl
Brilliant thank you! Updated
raven canopy
looks GTG!

Thanks so much for the second set of eyes!

@umbral dagger sorry. we broke your digital sand code with this:
https://github.com/adafruit/Adafruit_CircuitPython_LSM303/pull/3
umbral dagger
@tidal kiln Iâll revisit it. The renames make sense.
idle owl
@tidal kiln @umbral dagger There's already a PR into the Learn repo for the update.
umbral dagger
Ah cool
idle owl
@tidal kiln Thanks for catching that though! You are eagle-eye all over it!
I only caught it because I have the Learn repo locally and PyCharm caught it in the refactor.
tidal kiln
this one is affected also:
https://learn.adafruit.com/lsm303-accelerometer-slash-compass-breakout/circuitpython
@timber lion sorry. we broke your guide. ⏠(see PR link a few comments up)
tidal kiln
how so?
idle owl
I updated the example in the repo. If you click "view on GitHub" the file looks right. https://github.com/adafruit/Adafruit_CircuitPython_LSM303/blob/master/examples/slow_both/slow_both.py
I'll reembed it.
Or are you talking in the snippets.
tidal kiln
snippets and guide text
idle owl
Yah the guide itself. I see it now.

@slender iron FYI - built 3.0 after your latest commit - working fine on Metro_m4_revb, metro_m0.trinket_m0 -- still no go on itsybitsy_m0 - also tried feather52 even though no changes - still works đ

does it work in the alpha I released?
pastel panther
I just pulled like 10 minutes ago

it did not work just before your merge - was taht still alpha - ut was working yesterday.
I'll grap alpha and try it.

I even tried forcing it to build a new FS - did not help.
timber lion
oh gotcha @tidal kiln @idle owl for the lsm303 changes. yeah it looks like the guide text is updated but you might want to grab a new photo of the output, it still shows reading the accelerometer and magnetometer property
raven canopy
@timber lion did you get your veml6070 acting right?
timber lion
no haven't been able to find a good uv light source, but if you want to take a look that would be awesome too
just check if you're getting only 1 values from the raw read
it's odd that i was getting just 1.. but i want to get some real UV light to be sure
it's a 16 bit uint so it 1 is super close to 0 or a min value that made me think something might be up
this is with 2.2.3 too if it helps
on m0
raven canopy
ok, i can check it. using my desk lamp when i wrote it, i had to get it a little close. if i left it on my desktop it would stay at 0 most of the time...sometimes up to 3.
timber lion
oh gotcha, interesting
maybe 1 is expected then.. hrm i'd like to get a strong UV source to be sure it's reading something
i think i have some UV leds stashed somewhere though, haven't had a chance to dig through them all yet đ
raven canopy
yeah, i should probably take it on a journey outside. just don't have a mobile setup (yet?).
tidal kiln
@timber lion yep, i think @idle owl was able to update the guide except for that one screen cap. but noted that as needing to be taken care of.

How do I access the default code on the CPX? I can screen to it and see the output running but I can't interrupt it.
tidal kiln
you should be able to interrupt it with <ctrl><c>
cunning notch
@tidal kiln It's not interrupting. So CircuitPython is the what comes shipped on it?
slender iron
No, it doesn't ship with CircuitPython
cunning notch
What comes on it?
slender iron
either a makecode demo or an arduino fimata demo
cunning notch
@slender iron Okay, thanks
slender iron
np
pastel panther
@slender iron I'll take a peek after I verify the non-DMA code is working on my m4 board. I'm assuming the QSPI pins on the M4 Metro aren't broken out?
slender iron
nope, if I have time today I'll try normal SPI
I was up late last night working on it and now I've gotta prep to get outta the city this weekend
pastel panther
No problem. I was gonna look at QSPI anyways so I can finish validating my board
slender iron
kk
pastel panther
As a side note, I grabbed the supersized (SAMD51P20) chip to fill out an order so I might be making a jumbo m4 board before long
slender iron
nice!
pastel panther
those pins are dense
@slender iron I mean to ask; the micro-usb that you used on your ICE40 feather and were kind enough to share with me: did you make a custom footprint for it? I tried using it with the footprint from the feather and it's a bit off though I made it mostly work
slender iron
I usually make custom footprints
osh park is tricky because the holes usually need to be round
pastel panther
Ah, ok
tidal kiln
@cunning notch yah, what @slender iron said, got confused when you said you were able to attach with screen
cunning notch
@tidal kiln ampy didn't reply so I assumed something else. I don't have makecode installed.
tidal kiln
nothing to install for makecode, it's all browser based: https://makecode.adafruit.com/
cunning notch
@tidal kiln well that shows how much I've read up on it. lol
tidal kiln
@cunning notch no worries. with the CPX there are three ways you can program it:
- Arduino
- MakeCode
- CircuitPython
lots of options! more info here:
https://learn.adafruit.com/adafruit-circuit-playground-express/overview
cunning notch
@tidal kiln Thanks.
tidal kiln
oh. four ways. there's also Firmata đ
prime flower
@cunning notch The quickstart for circuitpython is https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart
timber mango
@tidal kiln a quick glance suggests firmata is just a protocol like bossac and is suggested by Arduino.cc:
https://www.arduino.cc/en/reference/firmata
EDIT:
It's looking a bit more like a tethered forth in some ways:
https://github.com/firmata/protocol/blob/master/protocol.md
^^ quote
*The intention of this protocol is to allow as much of the microcontroller to be controlled as possible from the host computer. This protocol was designed for the direct communication between a microcontroller and a software object on a host computer. The host software object should then provide an interface that makes sense in that environment.
The data communication format uses MIDI messages. It is not necessarily a MIDI device, first it uses a faster serial speed, and second, the messages don't always map the same.*

By programming Circuit Playground with a special Firmata sketch you can control it from Python and other code running on your computer.
The Adafruit github repo search function is suggestive of the fact that only the CircuitPlayground (not the CPX) has a Firmata sketch.

CPX uses Firmata for the Code.org implementation: https://learn.adafruit.com/adafruit-circuit-playground-express/code-org-csd

hi folks
I'm waiting for a CP disk to arrive (long shipping), but wondering if any of the MakeCode/PXT stuff would work with vanilla arduino boards. In particular UNO & nano
from what I can tell, I should only need to load the new bootloader & then it may be off to the races
timber mango
They had shown something on that subject in a recent video. Maybe Ask an Engineer, say 3-5 weeks ago.
Seems to me you just change the first term of the domain to reach the web site.
Something about adding your own board (though I can't imagine the details).
Q: What are the options for SPI with CPX? (Circuit Playground Express) when using CircuitPython 2.2.3? I'm exploring that question now, in the REPL.
frosty summit
@timber mango , yup, found maker.makecode.com
timber mango
that sounds like it, jakes.
frosty summit
what I'm looking for, long term, are its for STEM classes; something that's multipurpose. OTTO, SumoBot-JR, etc, programmable via mBlock, MakeCode, Python, JS
timber mango
Those are all SAMD21 boards on maker.makecode.com so it may be specific to that MCU.
frosty summit
... starting to lose me here...
timber mango
The UNO is an 8-bit board. The SAMD21 boards (usually branded as 'M0') are 32-bit boards.
frosty summit
from what I can gather, the requirment for MakeCode is UF2 bootloader
I see
ESP32's maybe?
timber mango
I am unfamiliar with ESPxx but some of them run CircuitPython, I think -- and therefore would be a candidate (I would think) for Makecode as well.
Uploading on those may be tricky .. too tricky to bother with.
tidal kiln
@frosty summit did you get a CP Classic or CP Express?
frosty summit
@tidal kiln - wanted to get the classic classroom bundle, but seems those are incompatible with CP. waiting on express, as want to spread usability - makecode, python, JS
tidal kiln
ok. cool. express is the one you probably wanted (so you can program multiple ways)
timber mango
https://github.com/adafruit/circuitpython/releases/tag/2.2.3
List of release files for CircutPython.
You can infer the names of the boards from the filenames of those .UF2 files listed there. That should be a complete list of supported hardware, and if it isn't on CircuitPython, chances are it's not supported in Makecode (unless I'm way off base, which is totally possible).
<< guesswork only
stuck elbow
oh wow, VL53L1 handles up to 4m distance!
tidal kiln
the UNO and nano are not powerful enough to run circuitpython, is there a reason why you need to use those?
frosty summit
found this, but have not tried yet: https://github.com/mmoskal/uf2-uno
tidal kiln
you need more than just the bootloader
you also need a procesor powerful enough to run what gets loaded via the bootloader
timber mango
I can't be enticed onto an Uno (they arrived on the market long before I took interest) but that .UF2 thing for the Uno looks nice.
If you own an Uno already, certainly worth investigating.
https://makecode.com/blog/uf2-for-arduino-uno
stuck elbow
the main problem is ram â you need at least 16kB ram for micropython/CP, iirc, and UNO has what? 512 bytes?
timber mango
Haha.
frosty summit
perfect! this is exactly what I was looking for. thanks. I would've completely overlooked that
timber mango
https://en.wikipedia.org/wiki/ATmega328 << should be the Uno chip, right?
stuck elbow
2kB
stuck elbow
that's 510kB more than the UNO
frosty summit
can run micropython, unsure re CP & MakeCode
stuck elbow
esp8266 has 90kB and can run CP
timber mango
So. SPI on the CPX.
I don't see no pins for that. Not sure what to wire to, to access MOSI and SCK.
solar whale
@timber mango https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/boards/circuitplayground_express/pins.c#L48 shows MISO.MOSI.SCK on A1,A2,A3 not in that order...
timber mango
Haha Thanks Jerry!
solar whale
sck = A1 MISO =A2 MOSI = A3
timber mango
I can see it on the schematic for CPX -- this is great. Can't wait to try it in hardware.
solar whale

timber mango
I'm sure Jerry gave me what I need. Can't fight city hall, so I won't state what I learned.
solar whale
@timber mango - other than the pins.c file did you find any other corroboration? you mentioned the schematic, but I don't see it there.
timber mango
It's PA05 on the schematic jerry.
So I am trusting the code you linked to be accurate to PA05 (which I understand well enough). SCK is PA05. MOSI PA07. I don't need MISO for the ST7565 LCD (which is why I'm investigating -- already have it going on the Trinket M0 using hardware SPI).
solar whale
ah yes -- also higher up in the pins.c file đ https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/boards/circuitplayground_express/pins.c#L6
timber mango
Yeah I've done this once before -- that's right, the mappings are direct further up this file.
Good catch.
Okay the schematic for CPX needs an annotation that mentions
SERCOM 0: external SPI in order to match what is already presented (in similar manner) in cell C1 of the schematic (upper left area, just above SAMD21 /RESET pin).
solar whale
@timber mango hmmm - I tried a quick test ```
Adafruit CircuitPython 2.2.3-dirty on 2018-02-11; Adafruit CircuitPlayground Express with samd21g18

File "<stdin>", line 1, in <module>
ValueError: Pin PA21 in use
@timber mango -- aha - the pins.c I showed tou was for 3.0 --- for 2.x they are different !!
timber mango
Thanks jerry. I will be testing this soon. No problem -- you gave me the piece I was missing; hopefully I will suss this out.
I'll report back here in pig-latin to fool the ot-bay.
solar whale
I think for 2.x the MISO/MOSI/SCK refer to the internal SPI, not the external -
timber mango
Okay I was worried about that already -- the internal SPI flashROM vs external SPI peripheral a user might interconnect with. but go, shoo .. enjoy your people wherever they are.
solar whale
timber mango
Yeah that's the flash MOSI and SCK which was what I was trying to side-step. Maybe 3.0.0 is the answer for me here -- just upgrade CPX to itt.
solar whale
I think you can use 2.x but just have to use the A1/A2/A3 names. Will test later.
solar whale
@timber mango - last post .... spi = busio.SPI(board.D6, board.D10, board.D9) cs = digitalio.DigitalInOut(board.A4)
that worked - I was able to mount an SPI SD CArd
it did not like the A1/A2/A3 ...
timber mango
I had the opposite experience, @solar whale - I could not use board.D10, but board.A3 does work.
Adafruit CircuitPython 2.2.3 on 2018-02-05; Adafruit CircuitPlayground Express with samd21g18
>>> import board
>>> data = board.D10
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'D10'
>>> data = board.A3
>>> (no error was reported)
However, SPI seems slow, though I cannot quantify that. I can count to two Mississippi before a routine that writes to every location on the (1024 byte) LCD memory completes.
File "main.py", line 78, in <module>
ValueError: MOSI and clock pins incompatible
51 # clk = board.A1 # make connection at pin A1 for CPX SCK A1 SCK PA05 D6
52 clk = board.A2 # make connection at pin A1 for CPX SCK A1 SCK PA05 D6
78 spi = busio.SPI(clk, MOSI=data)
When I moved SCK onto A2, it broke, suggesting that A1 was (already) correct here.
In other words, if there weren't special pins then it shouldn't have mattered which pin was assigned to SCK. So it would seem that 'SPI is happening'. ;)
idle owl
@tidal kiln @timber lion Screenshots updated.
tidal kiln
@idle owl awesome
timber lion
oh rad, thanks!
idle owl
Np
solar whale
@timber mango there are special pins. D6 is A1. Iâm not sure which As and which Ds are usable but they are the same pins. Iâll do some experimentation tomorrow. Main point is SPI does work on the CPX in 2.2.3.
timber mango
https://github.com/adafruit/circuitpython/blob/2.x/atmel-samd/samd21_pins.c#L52-L65
https://github.com/adafruit/circuitpython/blob/2.x/atmel-samd/samd21_pins.c#L155-L175
The lines above seem to suggest:
- There is no primary SERCOM on these three pins: PA05-PA06-PA07
- SERCOM0.1 .. 0.2 .. 0.3 .. are the secondary SERCOM's for these pins
The 'A' and 'D' pin assignments account for target board variants, but PA (PB) port pins are endemic to the chip itself.
Until I know better I'm going with the idea that any unclaimed SERCOM is worth investigating for use with SPI, when it is non-obvious (to me) what are the correct pins to use (or better, choices of correct pins).
I'm guessing that crossing SERCOM boundaries isn't allowed; so if you use SERCOMx for SCK you cannot then use SERCOMy for MOSI with the same peripheral.
solar whale
@timber mango you are delving much deeper than I have. I was just trying to demonstrate that the âpre-definedâ pins did work. I have not wrapped my head around SERCOMs yet.
timber mango
Oh haha. I'm out of my depth, but my guesswork sometimes is functional, just the same.
pastel panther
@timber mango I'm pretty familiar with sercoms on the SAMD boards; let me check the schematic and datasheet
timber mango
I have a Feather M0 Express ready to go, and it has lots more pins to investigate.
solar whale
And the SPI pins are labeled đ
pastel panther
@timber mango can you use any pin on the CPX or are you trying to avoid certain ones?
timber mango
Well I mean that's almost trivial; the idea is to discover which other pins are suitable (if any) for hardware SPI. I guess I need to see if the pins on the CPX MCU itself are the same ones brought out as SPI on the Feather M0 Express, for example.
siddacious: Any are fine on CPX; I have a five-pin interface to account for but three are GPIO -- just need SCK and MOSI for SPI (it's the ST7565 LCD)
pastel panther
k
timber mango
Okay, if the spi flashROM is taking up an SPI SERCOM, and I still have another SERCOM suitable for SPI on the Feather M0 Express, it stands to reason that (at least) two SERCOMS may be assigned on the same MCU to SPI duties, and it'll be hardware SPI (not bitbanged).
pastel panther
@timber mango D6 as SCK and D7 as MOSI should work
timber mango
On CPX I had to use the A names to succeed in Circuit Python 2.2.3
timber mango
So you're saying PA20 and PA21 (irrespective of target board config) scratch that
pastel panther
We're talking about the CPX, right? that's PA5 and PA6
timber mango
pastel panther
You should also be able to do
SCK=A3
MOSI=A2 or
SCK = A1
MOSI = A3
timber mango
Okay because they're the same SERCOM0.x group.
pastel panther
Yea, SCK can be on pad 1 or 3, MOSI on pad 0,2,3
timber mango
ah! that'll be fun swapping them around to see it work! I don't know how to tell if it's not really SPI, or if it's simply always SPI (you would then have to rewrite the main theory of the program to bitbang false SPI).
solar whale
@pastel panther thanks for the Rosetta Stone! That helps a lot.
pastel panther
what do you mean by "not really SPI or "always SPI"?
timber mango
Terribly stated.
pastel panther
@solar whale hah, that's nothing; I'm working on an even more rosetta stone but it will take a while
timber mango
I meant to suggest that it may be possible for the program to simulate SPI if hardware SPI wasn't available on that set of pins.
pastel panther
yes, for sure. CP will throw an error of some type (that you can catch I assume) if you get the combo wrong
then you can just bitbang
timber mango
I don't know what a successful failure looks like -- if its possible for the SPI LCD to display correctly, but at a slower speed, if you programmed it for hardware SPI, but chose the wrong pins to do it on.
So far the errors thrown have been obvious as to their meaning. I'm worried about having software SPI going and not knowing it.;) Does that make sense?
pastel panther
I don't think it will switch automatically so you should know based on how you code it.
you could have some indicator if it switches to bitbang
timber mango
That's what I needed to know -- that helps a lot.
I've already done the bitbang version and they're nothing alike.
solar whale
I ran into this yesterday with the adafruit _dotstar.py driver. It does bit bang if HW fails. Silently..
timber mango
bitbanged SPI, ST7565
pastel panther
@timber mango are you aware of bitbangio?
solar whale
That was why I thought the itsybitsy dotstar was working but it was using bit bang.
timber mango
@pastel panther I've heard of it and probably glanced through it.
pastel panther
@solar whale I don't know if you caught the convo with scott? dan? but the itsy bitsy m0 is stuck doing bitbang for the dotstar because of how the board is laid out
the dotstar clock pin is hardwired to a pin that can't be configured as a SCK
solar whale
Yeah. I saw that, I just did not appreciate how clever the code was to automatically work around it https://github.com/adafruit/Adafruit_CircuitPython_DotStar/blob/master/adafruit_dotstar.py#L73
timber mango
Probably this very conversation is what got me concerned I was doing non-hardware SPI without a code change. ;)
pastel panther
hah, no that's a feature of the library consuming the SPI lib, not the SPI lib itself
fair concern though!
timber mango
Well this is my first attempt at porting an unsupported peripheral that uses SPI, so I'm not sweating it at the moment. It works (at all) which I wasn't expecting to happen, so soon.
If it's running slower than it needs to, that'll eventually come to light, I'd think.
solar whale
Sound like you are making great progress!
timber mango
Thanks! The main puzzle right now is the framebuf -- I had to use a fake one tony wrote for devices that cannot support the internal one, when using Trinket M0 for this (it works!) I have three boards running ST7565 LCD now (feather m0 expr; cpx; and trinket m0)
The bouncing ball example code for SSD1306 runs so there's some sense of graphics going on.
solar whale
I fought with that a long time ago wit ssd1306. Good luck!
timber mango
Hahaha. The memory is paged so the bouncing ball crosses though an 8x128 pixel window (a 'page'). I don' t have much of an idea (yet) how to get it to use the entire LCD display area for the bouncing ball stuff. I was able to move it, though -- it wasn't intersecting the window in an interesting way, so I changed the points at where it bounces. Very satisfying result.
solar whale
Time for bed here. I learned a lot tonight. Thanks @timber mango @pastel panther goodnight!

Solid purple neopixel, no mass storage mount, and no COM port in the device manager.

You can still get into bootloader mode?

I suppose "bricked" is a relative term. I would say "3.0 is broken on a trinket m0"

Sure thing. Fortunately I have a second one right here to test Katni's guide....

@drowsy geyser 3.0 seems to be working fine on my trinket

the dotstar is actually turned off in the board files for the trinket

Hello everyone, does a logic shifter replace the need for a capacitor and resistor when wiring LED's?
raven canopy
I don't think they would work that way; think the current is too high for level shifters with regard to LEDs. but, I haven't used them in that sense, and haven't researched it so I could be way off.
runs to google đ
humble mural
@raven canopy I have been in Google for an hour. When I see a shifter I don't see capacitor/resistor combo.
raven canopy
is this for "regular" LEDs, or neopixels?
pastel panther
@humble mural are you talking about wiring up neopixels? or a current limiting resistor for a normal LED?
humble mural
@raven canopy All my research has been on Neopixels not regular (students want to make a marquee). @pastel panther wiring Neopixels. and controlling them with a Raspberry Pi 3
raven canopy
ahhh. the cap would still be advised. the resister...shouldn't be needed.
pastel panther
The level shifter is used to make sure the logic level of your controller is close to that of the voltage that the neopixels are running at
raven canopy
assume you're using a separate power supply for the neopixels?
humble mural
I would use logic shifter to handle the 3.3V to 5V issue betrween RPi3 and NeoPxls, but do I was under the impression that I needed a capacitor and resistou also
errant grail
I always add the cap for stability and a resistor for input voltage/current inrush protection, even with a logic level shifter.
pastel panther
ya, that's pretty good practice
errant grail
Older neos are a bit more sensitive than the newer ones, though.
humble mural
Ahh that was my next question. I power the RPi3 using the onboard plug and I power the NeoPxls with another adapter.
raven canopy
does the Uberguide cover RPi? I can't remember...
errant grail
@compact solstice That's why the poor little Neo needs some protection. If the pixels are powered down, they could be damaged by the input signal.
humble mural
I have to re-read that, its been a while and I was much greener and didn't understand it all., now at least I can sort off speak the language.
pastel panther
it's a pretty good reference
raven canopy
alright. i'm doc'd out for today. heading to dreamland... (not disney). đ¤ night đŚs!
humble mural
Can 32 x 128 NeoPxls be wired in such a manner as to make a marquee. Students want to make one that can transmit a message.
@raven canopy Good night, thanks for your help as always!
pastel panther
sure they can; the hard part will be the software, but it shouldn't be that bad
well, bad is relative
you can essentially make one 4096 pixel strip (can they go that long?)
errant grail
... and an array of 4,096 neopixels can eat up a lot of MCU memory
pastel panther
also that would be prohibitively expensive I would think
You'd do better with normal leds and shift registers
errant grail
You can send data out more than one pin to 1) reduce the number of daisy-chained pixels per pin and 2) to increase the refresh rate.
Oh -- forget the comment about MCU memory since you're using a RPi.
humble mural
That project can be done with regular LED?? That would help. We new that it was going to be expensive, but they actually willing to fundraise to for the NeoPxls (It's amazing how much money a group of young people rasie selling oreos and rice krispy treats)
pastel panther
I mean a huge neopixel display could do some really cool stuff but it would be order of magnitude more software, and $$
tidal kiln
@compact solstice are you limiting yourself to circuitpython?
humble mural
We would like to, I only program in Python and Java and I only want to teach those two. If I have an over eager student that want to learn Arduino (C++) they can on their own.
pastel panther
@humble mural yes, (almost) anything you can do with neopixels can be done with regular leds. It's jus a matter of how much work. Here is an example that's similar to your idea just in a different shape, done with rgb leds. You could do the same with single color leds and it would be even easier and less expensive:
errant grail
Is my calculator correct? 4096 neopixels at 20mA each totals 82A (~410W)!
pastel panther
that sounds about right
errant grail
and 20mA is the low end.
humble mural
So I would need a comluter psu?
errant grail
This will be a very fun project! I'll buy some treats!
pastel panther
That would be a beefy power supply
errant grail
You could power it in sections pretty easily.
humble mural
I have a couple of 450W that we have salvaged from old computer and I think even a few 550W.
pastel panther
@humble mural Maybe? I think it depends on the power supply. I'm not sure if they do their rated power on a single rail or split between 12v and 5v
humble mural
@pastel panther I have seen that project, in fact, the a couple of students in our electronics program are working on it. It's a cool project.
Yeah, I'd hate to burn 4096 LED's in a moment.
pastel panther
Were you to take something like this on you would obviously work up to the full size with successively bigger tests
humble mural
I have two PSu's that have both 12V and 5V, I just have to read what the 5V rating is.
As their teacher I try to limit the mistakes, not necesarily eliminate them. My suggestion was to purchase 4 32X32 RGB LED Matrix's and do it that way.
That way, they could program one, then add two, and so on. plus cost is cheaper
and they are already mounted
errant grail
... and usually have single byte-wide data inputs (sometimes with a control input) and ability to daisychain from panel to panel. Good idea. https://www.adafruit.com/category/327
humble mural
I like starting with one of these https://www.adafruit.com/product/2026 then when they get it working add another, then add the last two.
Look at this...... I'm lat to the dance again. Lucky for me Adafruit beat me to the punch https://learn.adafruit.com/16x32-rgb-display-with-raspberry-pi-part-2
errant grail
Yeah, they have a nice LED matrix hat and some great examples. Pretty do-able.
Looks like you're on a good pathway. Time for me to join the fam for popcorn and the late news. 'Night!
pastel panther
@errant grail how do you prepare your popcorn?
errant grail
Pretty easy since we're focused on low-fat, low-sodium. Microwave Orville R's.
pastel panther
not air popped?
errant grail
Not yet. We get the SmartPop version, I think. Still has some flavor. The days of dripping tasty stuff over the popcorn have passed.

Tony! I figured you'd be on a mountain today. đ
timber lion
ah that's tomorrow đ
raven canopy
nice double arcs, tony!

@drowsy geyser The only thing I've heard is that they now have the chips so it's probably a matter of locking the board design and sending out for the pcbs. Scott and Dan are working with a QSPI rev d version of the board which I imagine is pretty close to the final board. I'm not sure weather or not they're waiting on CP 3.0 to release but it wouldn't surprise me
drowsy geyser
@pastel panther Thanks! I was wondering if they were taking a hard dependency on 3.0 for the release....
pastel panther
It would make sense given that a lot of the excitement about the '51 seemed to be about how it would help CP
drowsy geyser
Agreed!
pastel panther
hey @timber lion did I hear that you put together an altimeter? Presumably with the MPL3115A2?

Sounds like M4 will initially only be supported on CircuitPython 3.x (not 2.x) and (guesswork:) Arduino. If the software is not stable, they probably would wait to release the hardware until some milestone was reached in the software base. /wild_guesses_dotcom
I'll try to install M4 for Arduino right now and see if it's a thing or not. ;)
drowsy geyser
That makes a lot of sense, @timber mango . I kinda thought that might be the case, but I wanted to ask instead of assume. đ
timber mango
Not seeing M4 support in Arduino from Adafruit. I'll comb the actual .JSON file to see (should be published there, first, I'd suppose).
huk do you have a web describing your pet project?
pastel panther
I think I saw or heard of m4 support somewhere. I'm pretty sure someone at adafruit released a mp3 decoder that runs on the m4
timber mango
I've seen something, I think. Just can't remember where. Adafruit usually has software on the hook that you can install, before you can get your (hot little) hands on the hardware itself. pIRkey is out, mostly, in software. Not available for purchase yett.
ItsyBitsy M0 was out for a few weeks in the Arduino IDE (I think) prior to release of the first shipment of doo-dads.
pastel panther
timber mango
yup yup yup
drowsy geyser
@timber mango No web page yet. It's on the todo list. I just realized I need four more Raspberry Pi 3s - one for each pair of motors - because the motor driver hats I'm goin gto use can only drive one pair.
(and there are eight motors - one each for the hub drives on the wheels, and one for each of front and rear axles)

Hmmmm, maybe they're going with a CP-only release.
timber mango
They did a thing for fururama fortitude fandango f-os where they did not proclaim a new repository on github for CPX -- reused the CircuitPlayground (-express).
Whatever the facamolus was, it's a protocol like MIDI that acts like a tethered forth, when employed with Arduino.cc special sketch.
drowsy geyser
Oooh that's interesting....
timber mango
It's in the scroll back for yesterday or the day before, probably in this chan.
It's a sleeper -- CPX is also in there!

@solar whale a thousand thanks for the PAxx PBxx mapping info in circuitpython. I had no idea it was that flexible!
pastel panther
@drowsy geyser why not make a hat with the number of controllers/h-bridges you need?
I'm sure you could find an adafruit board to base it off

@pastel panther It's a rather big rover. I need 120 Amps.
pastel panther
Per wheel?
A pi per wheel just seems excessive to me when a tiny85 could handle it
drowsy geyser
Oh no no, not that big. That's total.
pastel panther
heck, a tiny10 could probably do it
drowsy geyser
Honestly, I'm not that confident in my design skills. I'm trying to stick with off-the-shelf components.
But I am going to have to break out KiCad and design the power system board to keep the banks of LiPos charged up from solar panels.
pastel panther
How are you planning on having the pi's communicate to the "brain"?
drowsy geyser
Yes, absolutely. There's an onboard network.
The other p roject (the high power rocket flight controller in CP) is done and built.
pastel panther
did you open source that? What do you have for a IMU? I have a BN0055 that I'm planning to use for something vaguely simmilar
drowsy geyser
I am totally going to open source it once it's flight validated. It's based on the Feather M0 Express. It has a BME280 and BNO055 onboard for dynamics analysis.
pastel panther
are you using the BME for control or just altitude monitoring?
drowsy geyser
Now I'm building a 62" x 4" High Power Rocket around it. đ The BME is just for altitude.
pastel panther
Is it a fully custom board or a feather wing?
drowsy geyser
The BME280 controls the separation explosives. When it drops one meter past apogee it fires the drogue, and then at 500 feet it fires the main chute.
I use Feather Wings for most of it, though I built the two breakouts on FeatherWing Proto boards.
pastel panther
I would be cautious about using a BME for calculating the parachute deployment. Have you done the math on the error margin?
wait, I missed that you're using a drogue
that shouldn't be too bad
drowsy geyser
No, but I've tested it in slow motion (success) in a building elevator, and I'm going to flight test it on a rocket with other electronics several times just to collect data.
