yeah, for that you'll need to ask in the micropython support forums
we've never used what you're doing 😃
twilit geyser
do you have any idea? maybe something like this happens with cPY?
meager fog
some change in their API, but we have no idea what it could be
twilit geyser
thanks.

Good afternoon. I recently got a circuit playground express and one thing I'd like to do is use it to update my data acquisition prototype. I was using pyserial to pull data from an arduino and write it to a csv. I'd like to do the same with my cpx. Right now I just have it printing (to console) the temperature and light readings. Is there a simple way to get those readings saved to a file? I've updated my pyserial script to read from the cpx com port.
marble hornet
ahg, @idle owl it came back
pylint: disable=too-many-arguments,disable=too-many-attributes
idle owl
Only the message after the comma
# pylint: disable=too-many-arguments,too-many-attributes
marble hornet
👍 works
minor blaze
so does anyone care to browse over my code and see let me know if they think it would run on a neotrellis m4?
marble hornet
but it doesn;t like the line that is doing the disabling
gfx.py:71:0: E0012: Bad option value 'too-many-attributes' (bad-option-value)
idle owl
What version of pylint are you using? Are you still linting locally?
Because typically I see that if I lint locally with a different version than remotely and some checks aren't in both versions of pylint.
@marble hornet Do pylint --version
teal bear
@misty wolf If I understand what you are doing, I think the same code - I would recommend putting it on github so we can take a peek
idle owl
@marble hornet Ok, hold on, you should be running 1.9.2. Try running pip install --force-reinstall pylint==1.9.2
That's what we're using because it will be an overhaul to update to 2.2.2. And we're not ready for that yet.
marble hornet
hmmm same errors though
idle owl
Ok. To clarify, if you remove too-many-attributes it gives you that error? But if you add it, it says "bad option"?
Did you spell it exactly right?
marble hornet
R: 46, 0: Too many instance attributes (10/7) (too-many-instance-attributes) if i have # pylint: disable=too-many-arguments
idle owl
You didn't type it correctly.
It's not too-many-attributes.
It's too-many-instance-attributes.
That's gotten me before 😃
misty wolf
@teal bear will do, I don't use github often, is there a particular place/forum/subthread I need to post it? Thank you for your help
idle owl
So if you type it incorrectly, it is not a valid option, and will give you that error.
marble hornet
okay, i switched it back to under class and spelled it correctly. thank you
idle owl
Yep!
marble hornet
okay i;m down to one last one !!
an import error for the font, yet it is working fine since i'm editing right on an m4

i have the adabox 10 and i put the christmas soundboard on there and then it booted up said the merry christmas then everything stopped working pls help
idle owl
@marble hornet Paste to me what your results are from the linter
marble hornet
E: 94,16: Unable to import 'adafruit_gfx.fonts.gfx_standard_font_01' (import-error)
------------------------------------------------------------------
Your code has been rated at 9.82/10 (previous run: 9.75/10, +0.07)
Ok, I want you to push to GitHub. It may be a local issue.
Because CircuitPython is a bit odd in that the libs aren't necessarily available to your computer because they're located on a board when CP is actually running.
So sometimes remotely it works fine. If it doesn't, we'll sort it.
teal bear
@misty wolf if you are going to write code (like you are) you should get an account somewhere that you can check your code into. (like github) If you have an account, use it.
misty wolf
@teal bear will do, thank you very much. I'll post it shortly.

@meager fog finally getting around to updating the guide for the miniesptool -- I uploaded the newer particle argon esp32 files and put in a PR to the miniesptool library for the example script. I assume you wasnt me to add a section to the guide for uploading the ESP32 AT Firmware to a Feather Huzzah ESP32 via USB -- Il'll try to get that in tomorrow.
meager fog
@solar whale i think im confused by your PR 😃
why would u use an esp8266 with argon? :/
solar whale
I just meant to update miniiesptool_esp32multifile.py so the checksums are correct for the new zip file I put in the guide
do you want a different name than miniesptool_esp32multifile.py?
meager fog
i think maybe make an esp32argon
keep the current example as is? cause the esp32 argon build is 'special'?
like, a new example
solar whale
Ok - so leave the miniesptool_esp32mutlifile.py as is -- but there is no .zip that will work with it
meager fog
np just upload it to the guide
solar whale
I upladed the new argon .zip -- what .zip shold the miniesptool_esp32multifile point to?
the new .zip will work with a new miniesptool_esp32argon.py
the only other esp32 build I have is the full AT firmware build for loading via USB, not via miniesptool.
sorry if I confused things
meager fog
the miniesptool will point to a version for the m4
just keep it as is
make a new example for argon
solar whale
ok - but we don't now have an external esp32 load for the M4 that uses miniesptool. and for the feather huzzah ESP32 -- USB is a lot simpler since the pins for uplooad are not available.
the miniesptool load for the esp8266 is fine
solar whale
@meager fog my PR remove miniesptool_esp32multifile.py -- do you want me to restore it
meager fog
@solar whale the current example is for m4, we'll adjust it if necessary - make a new example for argon
and it can have the crc32 for the argon build
dont worry about m4 - its a idfferent crc set anyways
solar whale
OK -- new example is in the PR -- I'll update the pr to restore the old example
@meager fog sorry about all that confusion -- I'll work on the guide tomorrow.
meager fog

looking at the wrong code.py
ruby atlas
Oops 😃
What's the recommended dev environment for CircuitPython (C code) these days? VS Code with custom path setups?
(It's been a while)
tulip sleet
@ruby atlas not sure what you mean - I use emacs, Scott uses vi. We don't use an IDE.
exotic pumice
hey @tulip sleet, someone was looking for a Feather M4 eraser UF2 earlier today. I couldn't find it. Is it the same as the Metro?
tulip sleet
Not necessarily. Could be different pins. I'm not sure we have one built.
exotic pumice
ok, I wasn't sure whether the erasers just zeroed everything or are they stock firmware?
tulip sleet
did they want to clear the internal flash or the SPI flash chip?
exotic pumice
I'm not sure, whichever would help them.
"
I kind of bricked my Feather M4 for CircuitPython, whenever I flash any circuitpython version it doesn't boot anymore and I cant get into the REPL to format the flash. Going into bootloader and flashing Arduino sketches works fine
I think this happens after I tried to write a new library to it and ejected it as it didn't start the file transfer for some reason, after that it never came back up as the cpy drive
any ideas maybe? :/
I need some way to erase the flash without using cpy"
sorry for the ping
ruby atlas
@tulip sleet I've used CLion,VS Code, and Sublime Text while working on Circuit Python code. Because of the dynamic build environment, none is really able to provide great autocomplete. I did get VS Code to behave somewhat OK by mucking around with include paths and defines. 😃
tulip sleet
@ruby atlas I just use emacs abbrev mode, which does autocomplete based on the currently open buffers.
certainly not perfect
ruby atlas
😃 I don't think we can really expect perfect with the number of targets and conditional compiles.
tulip sleet
@exotic pumice the latest alpha.5 has a special way of getting into safe mode: it illuminates the RGB LED yellow for 700 ms and if you click the reset during that time, it will restart and go into safe mode. It's basically a "slow" double-click.
I'm thinking you may have a main.py that is crashing
exotic pumice
thanks dan
tulip sleet
@exotic pumice I'm not sure I'm actually getting this to work, but the code is in there :/
solar whale
@gentle bronze sorry it has been so difficult to get the ESP8266 programed. The same problem happened to me the first time I tried it but I don’t recall what eventually got around it. I have successfully loaded the AT firmware to a few ESP8266 breakouts via an feather M4 with miniesptool. I need to get some sleep now. I’ll try to reproduce this tomorrow.
gentle bronze
@solar whale please get some sleep, i have just finished lunch, I will try to use m4 to program esp breakout, not sure why ftdi program failed. No worries
I am new to esp, I may not do things properly, happen all the times :)
Thank you very much for your help. Good night
solar whale
You are very welcome!
solar whale
@gentle bronze very strange. Have you tried flashing Circuit Python onto it again just to see if that works?
solar whale
@gentle bronze ah -- I have reprduced the ESP8266 blinking blue failure -- now to see if I can get out of it!
@gentle bronze yes -- success -- I will post the details to the issue -- basically -- I pre loaded CP to the ESP8266 then flased AT _Firmware without erasing (used FTDI cable) -- It now works.

@gentle bronze np -- good luck -- just load CP then reload AT...

@solar whale it did the trick, I see the ready mess now when reset
hmm but it does response with AT command manually entered with minicom
solar whale
@gentle bronze yay! -- It wont work wit minicom -- try miniterm.py
gentle bronze
that is weird 😄
solar whale
it is very fussy about the End of Line and I cant get screen or minicomto work
or try hooking it up and us the small test program to talk to it.

Do you have a recent version of CP on your board -- 4.0.0-alpha5?

gentle bronze
ok it work, i have to change your script a bit to get it work with minicom, too lazy to change to other terminal 😄 uart.write(bytes(data+"\r\n",'utf-8'))
finally, we could troubleshoot the real issue 😄
solar whale
great -- I can trigger the failure on the nrf5284 eitehr by pressing the RESET on the esp8266 or by sending the "AT+RST" command for AT+RST you get a fluury of responses, but then it does not repond any more -- Control-D will clear it . On the M4 -- these do not cause it to hang.
gentle bronze
ah yeah, I saw this as well
solar whale
I did find that if I manully configure the uart in the REPL, I can clear the "hang" by deinit() then re-initialize the uart.
gentle bronze
sounds like an currupted state issue with uart io
solar whale
see -- you have almost fixed it already 😉
@idle owl is the CP meeting today at 2PM EST?

@marble hornet i think you just need to add a blank line after this line:

The command "cd docs && sphinx-build -E -W -b html . _build/html && cd .." exited with 2.```@tidal kiln it failed
what sequence of characters starts an emphasis?
tidal kiln
the docstrings use restructured text syntax, and i'm no expert on rst 😦
i think it's *emphasis*
looks like maybe you have *emphasis, so are missing the closing *
here:
https://github.com/adafruit/Adafruit_CircuitPython_GFX/pull/6/files#diff-9ad1ea72b2a68905febc26c5c65b424bR40
and here:
https://github.com/adafruit/Adafruit_CircuitPython_GFX/pull/6/files#diff-9ad1ea72b2a68905febc26c5c65b424bR50
if you meant for those to be bullet list entries, then need a space: * list item
tidal kiln
also, fyi, the line number is in the error message:
/home/travis/build/adafruit/Adafruit_CircuitPython_GFX/adafruit_gfx/fonts/gfx_standard_font_01.py:docstring of adafruit_gfx.fonts.gfx_standard_font_01:26:Inline emphasis start-string without end-string.
so in this case 26
but the count is relative to the start of the docstring, so it's not the actual line number in the file, which is...fun.
marble hornet

tidal kiln
count is relative to docstring. not file.
marble hornet

line 23 = line 1
main meteor
It says "block quote ends without a blank line". Seems like an easy enough fix.

@meager fog Let me know if you need more information about the issues with the AT_Firmware_1.6.2.0.bin file that @gentle bronze and I worked through this morning - Could it be an issue with the file?--- Can you tell me how the file was built - I can try to reproduce it and see if there is an issue with it. see the end of https://github.com/adafruit/circuitpython/issues/1407#issuecomment-450191714
marble hornet
thank you
meager fog
@solar whale i made it by burning in that version ESP8266 firmware piecemeal, then pulling it out as one big file
w/esptool.py
solar whale
Hmm -- then it should be OK --- not sure what is going on.
I'll poke at it some more
idle owl
Sphinx is never easy.
ruby atlas
Hmmm. I either need a callback or to have pixelbuf.c call a python subclass method (if it exists) so that subclasses of RGBLED can implement auto_write. I wonder how hard that will be or if there's any examples of calling a non-C method in a subclass.
tidal kiln
@marble hornet this might help:
http://rst.ninjs.org/#
you can use that to work out the RST. i pasted in the docstring from your latest PR and it gives the same error message. so you can edit the RST there until it's error free and then paste back into your code.
idle owl
@tidal kiln @marble hornet I can help later today. I've gone through most of the errors you're going to see myself and have a good idea on what needs to be done to resolve them. Sphinx is picky and difficult.
I will have meetings until late afternoon at least, likely.
tidal kiln
RST = restructured text
that site let's you put RST markup on the left hand side and see the resulting output on the right hand side
marble hornet
Warning, treated as error:
/home/travis/build/adafruit/Adafruit_CircuitPython_GFX/adafruit_gfx/gfx.py:docstring of adafruit_gfx.gfx:1:'any' reference target not found: adafruit_gfx

@hardy horizon MKRZERO update-bootloader-mkrzero*.* files are now in https://github.com/adafruit/uf2-samdx1/releases/tag/v2.0.0-adafruit.8. Look toward the end of the list. (I made a new release that includes that new board.)
umbral dagger
Errands so I couldn’t even follow along this week. Hugs to everyone for contributing to 2018 being quite likely the best year of my career so far. Certainly the most enjoyable.
hardy horizon
@tulip sleet Thanks for compiling and uploading the MKRZERO files - much appreciated. I will begin to experiment - sounds like MU support is something to follow?
tulip sleet
@hardy horizon the next version of mu will take any board with the Adafuit USB VID (vendor ID), 0x239a. The UF2 bootloader for MKRZERO id's as 0x239a/0x0035. In the meantime, you can add that board to the adafruit.py file that's somewhere in the Mu installation
hardy horizon
@tulip sleet Thanks again, I've added 0x239a,0x0035 as a board ID to adafruit.py but no joy yet - I suspect I will get this working in the morning as its getting later here now. Cheers.
inland tusk
@idle owl This was my first time using the app on my phone and I did not find the mute switch until almost the end of the meeting . Sorry that won't happen again.
hardy horizon
@tulip sleet I tell a lie - I can now save and load via MU but for some reason the Serial port won't open - I guess that's another issue.
marble hornet
So what's the difference between displayio and gfx? (Besides c vs python level? )
upbeat plover
How do I strip first 3 and last 2 of a return, if i don't know what characters they will be?
solar whale
@upbeat plover carriage return is b'\r' line feed is b'\n'
solar whale
@upbeat plover you can use str.strip(b'\r\n')
that is if x is a string x.strip(b'\r\n')
exotic pumice
sorry, it took me a bit to get there but I think it's right now
now optimized, I wasn't sure if that would work or wrap
upbeat plover
how do i do that for a text string
solar whale
@upbeat plover sorry -- misunderstood -- ignore my comments
exotic pumice
strings are just lists/arrays of characters
yourstring[3:-2]
afaik
or maybe they're not but they're indexed the same
exotic pumice
yeah, the strip function is kind of confusing, it strips every occurernce of the characters you pass it
upbeat plover
anyone have FRAM and want to test this? the storing of strings and read of strings, and some other stuff
I have an issue with FRAM when I have other I2C stuff connected, it cant find the FRAM is this normal?
When I have si7021 and FRAM connected, si7021 works find but FRAM is unable to connect.
tidal kiln
should work. how is everything wired together?

@tidal kiln its working now... idk what happen before

aaah! didn't realise today was the cp meeting 😄
be-lated hug reports to @meager fog @solar whale for help with ESP+M4 stuff, along with the refresh of the display related updates, i've been pulling out some displays and esp's to try out over the holidays. thank you! 😃
@umbral dagger for all the awesome M4 Neotrellis tutorials, I had fun playing the memory game! (great demo mode!!) and flappy bird, gaming on a neotrellis m4 = ❤
@tulip sleet ty for reviewing my pull request on the Tagalog translation! Hopefully can bring in some Pythonistas from the Philippines to help improve on the translation for next year :), also for being kind and patient during my times of need here on discord!
@tidal kiln for helping me out with the AS726x stuff and creating subclasses for the library 🙇🏼
@slender iron for SPI flash related support throughout 2018 😂 Congratulations and enjoy Iceland!!!

exotic pumice
I got swd working on my metro m4 😃
Some tricky soldering to the pins holding the connector on later
and a bit of melted plastic
exotic pumice
now I just gotta get arm-none-eabi-gdb onto my pi somehow
or figure out why I can't access the port through my LAN
tidal kiln
did you solder on the metro side?
exotic pumice
@tidal kiln not sure what you mean exactly, I soldered on the top of the board, on the outside of the connector
tidal kiln
you can use ribbon cables
exotic pumice
I don't have a way to go from the 0.05" connector to 0.1" raspberry pi
I had an swd breakout but I broke it
reordered
exotic pumice
yup
tidal kiln
and rings a bell. we were talking about this already...
exotic pumice
I'm just impatient
tidal kiln
all good. just wanted to make sure you knew there were solderless options.
exotic pumice
yes, thanks
idle owl
@marble hornet None! It's simply for the purpose of being notified about important CircuitPython things. You're part of the CircuitPython community so you're a member.
marble hornet
😁😁
tidal kiln
@marble hornet actually, mild resp. in the future, you must help others climb the linting ladder, since you're a pro now.
tidal kiln
hey. me too.

Patience, young padawan.
marble hornet
I don't like sand
idle owl
Learning Sphinx comes from fighting with Sphinx failures. Eventually you have the same thing fail enough times that you remember what it takes to fix it.
marble hornet
cough cough classes?
idle owl
And then the next step after that is remembering to preempt the failures. Which takes even more time.
That's how it went for me 😄
tough flax
Hi all - hope you're having a great holiday season
tough flax
I'm trying to finish up a guide (my first!) and am having serial problems w/Linux
@tulip sleet tried to help on this a while ago and neither of us found a solution.
I've got CP on a Trinket M0 connected to a rPi 3B+ via USB. I'm trying to send data via serial to the device.
It totally works when I connect via minicom - I can type the commands and it just works.
But I'd like to script this, so I'd like a way to send the commands from the command line.
I try
echo -ne "\n\nred\n\n" > /dev/ttyACM0
And the trinket stops like it received input, but never acts on it.
It's like it isn't returning from input()
So I've tried everything I can to send different line endings
I've played with hardware flow control.. I cannot figure this one out.
Any thoughts?
exotic pumice
@tough flax I'd probably try something like this https://pyserial.readthedocs.io/en/latest/shortintro.html
tidal kiln
minicom running on pi also?
tough flax
Yes @tidal kiln (looking @exotic pumice )
exotic pumice
abstracts away the details of the protocol that are probably missing when you just echo to the device
tough flax
Ah - you're suggesting using python on the Pi as well?
exotic pumice
yeah
tough flax
it would require them to install pySerial module
might be a good fallback
hard to believe it's this hard to send a string to a TTY
Weirdly, the string "red", "green" IS sent to the Trinket... if I then connect via Minicom and hit enter it takes effect
tidal kiln
i wonder if you might need to do some stty on it to have echo work as expected
tough flax
Yes, that's what @tulip sleet and I were trying - here's the output of stty:
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;

tidal kiln
yah, i'm no pro
exotic pumice
eol = <undef> that's interesting
tough flax
yes, and then there's eol2
tough flax
echo 'green' > /dev/ttyACM0
cat < /dev/ttyACM0
reen
It didn't take the "\n" but did without the quotes (no difference)
tidal kiln
what's running on the Trinket? simple loopback?
tough flax
My HandRaiser code https://github.com/ATMakersOrg/Little-HandRaiser
It checks for input on USB, then reads the line & processes it
So, this works...
socat -t0 STDIO,raw,echo=0,escape=0x03 file:/dev/ttyACM0,b9600,cs8,parenb=0,cstopb=0,clocal=0,raw,echo=0,setlk,flock-ex-nb,nonblock=1

well...let me fire up a trinket and a pi....you running 3.1.1 on the trinket?
tough flax
No, 3.x as of two weeks ago?
😃
It's not picky though - the input() code hasn't changed
tidal kiln
oh wait. there's a UF2 in the repo - so just use that? copy to TRINKETBOOT?
tough flax
yep
tidal kiln
didn't work. is this the code?
https://github.com/ATMakersOrg/Little-HandRaiser/blob/master/src/main.py

@meager fog I have the Huzzah32 (3591) but won't get much time to look till after 9pm. Any getting started pointers?
tough flax
I'll push my latest just in case
You've got the latest now
I didn't build a new UF2
ruby atlas
@tulip sleet yeah it's not working quite right. Some things work, but many do not and I get random crashes from time to time 😃
tidal kiln
that's alright, i can just grab from main.py
but looks like i need 4.x:
AttributeError: 'Runtime' object has no attribute 'serial_bytes_available'
No, the latest 3.x has it too

@ruby atlas what will you be connecting to the ESP32. I can post a file that you can flash to the ESP32 to install the AT firmware on its UART
ruby atlas
That'll be a good starting point 😃
solar whale
If you hav an m4 then the demos in the ESPATcontol will work with it
tough flax
@tidal kiln its in the 3.x branch - I wrote the back-port for it
Not sure what release it went into
ruby atlas
@solar whale multiple M4s. I'll grab the Metro M4.
tough flax
Looks like that release that @tulip sleet talks about at the bottom didn't happen
Honestly, for this test, you can just replace that line with if (true)
the wheel and blink won't work, but changing colors will
solar whale
@ruby atlas here is the AT Firware for the Huzzah ESP32
tidal kiln
yep. looks like release didn't happen. latest 3.x is 3.1.1 on nov.2. that comment was nov. 4.

no biggie to just run 4.x

@ruby atlas -- you can use teh library from here (I htink it is in the latest bundle as well) and the demos in the examples should work -- see the demos code for the pins to wire up -- GPIO15 is critical for flow control - you need to connect RX,TX,VUSB,GND,GPIO15,RESET from the ESP32 to the metro M4 -- swap RX/TX - use the recommended or any other GPIO for the GPIO15,RESET

Ok, but it doesn't need anything fancy except that command

@ruby atlas - once you flash the ATfirware to the ESP32 -- you won't see anything useful on the USB port -- only via TX/RX.
good luck! ping me if you need anything
ruby atlas
As one would expect 😃
tidal kiln
not yet. figured i just try here before moving to pi.
tidal kiln
oh man. i hope i purged that long ago.
ruby atlas
> Don't forget you will also need to install the SiLabs CP2104 Driver
Or I can just use a Linux VM because last time I installed that I had more system instability.
@solar whale you don't have to provide an address to esptool.py?
esptool write_flash: error: argument <address> <filename>: Address "/media/psf/Home/Downloads/factory_WROOM-32.bin" must be a number
(trying 0x00000)
and back later!
tidal kiln
@tough flax trying minicom to sanity check. does this match your settings?
nvm. it worked.
tidal kiln
minicom's working though
tough flax
But minicom's reading
tidal kiln
ah. ok. and echo isn't.
tough flax
Right
tidal kiln
that's why you cat'd....hmmm
marble hornet
i have a github question :
so there is a pr and it says that there is still a request for a change but it was fixed some days ago
the one by scott
idle owl
It remains until the author of the change request marks it as approved. In any case, whoever does the final review can approve it even if the author of the change request does not approve it. So it won't be a blocking issue if someone else has time to review it.
marble hornet
ah, the wonders of github i see. it's like a summary?
idle owl
Yes
If someone approves, it'll show partially green on that circle, if another change request is still active.
tidal kiln
@tough flax or echo "\n" isn't really the newline input needs to see to return
tough flax
I tried \x0a as well
idle owl
@marble hornet I added the CircuitPython Librarians team to the repo so anyone on that team can review it now. And I requested a review from both the team and Ladyada. So it should be on our radar now.
marble hornet
😀 🙇 thank you sensei
tough flax
I've gotta eat dinner - thanks @tidal kiln for looking at this. I'm very frustrated 😕 Maybe later.
marble hornet
enjoy @tough flax
tidal kiln
@tough flax ok. no worries. it is odd. but should be able to figure it out. since it's just software. what's minicom doing that CLI isn't? etc....
tough flax
Yeah... problem is it's arcane 1975 knowledge that we'd need someone who wrote the original "more" command to help with 😉
tidal kiln
indeed
tough flax
(yes, that was a hat-tip to @tulip sleet but I couldn't figure out a way to sneak his ID into it 😃
marble hornet
now an okay time to throw up my hw designs?
idle owl
Anytime is fine. But I don't know who will be around when to take a look. It's not a skill I possess so I will be of no help on this one.
tidal kiln
mmmmm...castellated
marble hornet
excited or skeptical ?
tidal kiln
excited. that's cool.
marble hornet
it's a metro m4 in less than an inch square !
sans power supply
🤞 i'll have them up on tindie sooner than later
i;'m concerned about the u1. it's a microchip sram chip but it's on the same lines as the display spi with a different cs
marble hornet
if it is just driving the m4 itself
do you know , in the future, how i can figure out how much current a trace can carry
and would a schematic be helpful? thank you for that advice
here is the photos with the ground plane rendered
ruby lake
use the pcb trace width and thickness calculator, such as http://circuitcalculator.com/wordpress/2006/01/31/pcb-trace-width-calculator/
it will show things like temperature derating
solar whale
@ruby atlas correct -- should have been /usr/local/bin/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 40m --flash_size detect 0 factory_WROOM-32.bin
zeros don't count 😉
tough flax
Hey @tidal kiln I was thinking - it's possible that we're getting TOO MANY NL/CRs... it might be stuck on the NEXT loop - I can't test from here, but I thought I'd share
tidal kiln
hmm. maybe. i was think it might help to add some LED 13 on/offs in there to help determine where it's locking up
tough flax
I can't debug from here tonight, but I'll look again later or in the morning
tidal kiln
sure thing...was just something i was thinking...
tough flax
Not a bad thought
tulip sleet
@tidal kiln @tough flax I was afk for a few hours, but if there's something I can help with, let me know. I'm not sure what the issue is looking at the posts above
ruby atlas
@tulip sleet don't know if you saw my note - subclassing only sort of works.
exotic pumice
it's starting to look like the at91samd package for openocd doesn't support samd51
tulip sleet
@ruby atlas no, just got back here
tough flax
@tulip sleet same one as before... minicom/socat both control the trinket M0 via serial just fine on linux (rPi or not). echo "red" > /dev/ttyACM0 doesn't
ruby atlas
I'm tempted to do some debugging to figure out if I can avoid crashing and wrong behaviour. Otherwise I need to come up with clever ways to avoid having to hit python during [] operations.
tough flax
something weird with the stty or the like
tulip sleet
@exotic pumice yes, it's flaky enough with samd21
i tried a bunch of different stty settings but didn't figure it out. are you expecting \n \r\n or just \r ?
exotic pumice
@tulip sleet 😢
tough flax
It should work with either
exotic pumice
is there a suitable alternative package for openocd you know of?
tough flax
I was thinking it might be getting more, not less (I've been focused on getting less)
tulip sleet
@exotic pumice what do you want to do iwth openocd, debugging, flashing, or something else?
@tough flax can you write some kind of test program to record what it's really getting?
exotic pumice
debugging
when I said alternative, I meant alternative to the at91samd package, not to openocd
I like openocd and I just got it working
tough flax
I can, but not at this second - I don't have a power brick that can power my pi here
USB from my laptop is insufficient for the rPi3 B_
B+
ruby atlas
@tough flax I love my multiport Anker adapters.
exotic pumice
I just found this but I don't seem to have target/atsame5x.cfg https://gitlab.cba.mit.edu/jakeread/atkstepper17/blob/ad652ba5bd6f3ccb5ce7f52ac7e5ccfed9708891/embedded/openocd/program.cfg
tulip sleet
@exotic pumice some googling: http://openocd.zylin.com/#/c/4272/
exotic pumice
so I probably have to recompile openocd eh?
tulip sleet
@exotic pumice I guess, and there are multiple parts to that patch. I just found it referenced elsewhere and followed a trail
exotic pumice
I found this https://gitlab.cba.mit.edu/jakeread/atkstepper17/tree/ad652ba5bd6f3ccb5ce7f52ac7e5ccfed9708891/embedded/openocd
it has directions to install
unfortunately I'm having difficulty getting my pi cross compiler going so all of this is gonna have to compile on the super weak processor
and I'm using a new version of gcc so everything errors
fun times
exotic pumice
shoot now I'm not getting a gdb server again
solar whale
@meager fog I found a fix for the ESP8266 AT firware load after erasing the cip
two extra files are needed ```/usr/local/bin/esptool.py -c esp8266 -p /dev/ttyUSB0 write_flash 0 AT_firmware_1.6.2.0.bin 0x3fc000 esp_init_data_default_v05.bin 0x3fe000 blank.bin
the blank is probably not needed but I thin the esp_init_data_default is -- it is loaded as part of a Circuitpyhton build -- that is why the AT load works after a CP load
meager fog
@solar whale oh yay thank you!
wanna make a new bin?
i was working on ssd1306 stuff
ruby atlas
ESP AT GET URL http://wifitest.adafruit.com/testwifi/index.html

This is a test of the CC3000 module!
If you can read this, its working :)
----------------------------------------```yay
solar whale
since the missing file has to g at 0x3fc000 -- does the /bin have to be that big? or do we have to do it in pieces.
ruby atlas
I'm gonna need a lot more and M4 boards. I have a bunch of old things around the house to replace with CircuitPython stuff.
HUZZAH32
meager fog
oh yeha that works well
ruby atlas
Yeah, because it's adafruit hardware :-)!
ruby atlas
well, yeah, but adafruit boards aren't crap.
Currently - two humidity probes, a plant moisture probe, external temperature/pressure probe, garage temperature probes (so we know when to bring in the pop in winter), and an automatic humidifier controller that looks at the 24h forecast to set the target point.
meager fog
sending to adafrui.io?
ruby atlas
All of the above use my local mosquitto server to communicate with each other and/or homeassistant.
meager fog
hmm homeassitant is rest or mqtt?
solar whale
@meager fog you can do it in just 2 pieces -- the first AT_firmware_1.6.2.0.bin ad normal then a very small /usr/local/bin/esptool.py -c esp8266 -p /dev/ttyUSB0 write_flash 0x3fc000 esp_init_data_default_v05.bin
ruby atlas
@meager fog yes (both)
HomeAssistant is tons of things and is in python and is easy to extend.
solar whale
OK -- just for USB load -- for minesptool will need pieces.
solar whale
yup
meager fog
well, we got rest going
ruby atlas
I used to hackathon with them at PyCon but CircuitPython caught my attention in 2018 😃
solar whale
ok so we can jsut add the second step.
ruby atlas
I moved my Homeassistant to a VM, but it runs very nicely on Pi 3 B+.
They presented in the past, but many contributors attend PyCon too.
Speaking of PyCon I need to book my flights before the prices start going up.
@meager fog what do you want me to muck around with tomorrow if I get time, now that I have the hardware setup?
meager fog
oh so homeassistant uses the old Python/mmio version of our DHT library
and id like to move em to circuitpython
BUT its not ready yet!
ruby atlas
That'll be easy. They're also on Discord 😃
meager fog
i need to test on some Pi 1's to make sure it works there
its not as fast, we use libgpiod
ruby atlas
Hmm, Pi 1. I have one somewhere.
ruby atlas
Heh.
meager fog
i need help updating their code
its some module somewhere, but not sure where. all i know is they come into the github issues 😃
ruby atlas
That'll be easy. They're really good about merging PRs.
An move super fast.
And I'm sure I can help with the PR and ping the project's benevolent dictator.
meager fog
yay ok ill ping you when its all ready. we're almost done, probably last PR tomorrow to platformdetect
then we'll do the switcheroo
and i can 'kill' that old repo
its ghastly in there
☠
ruby atlas
Haha. Their users don't move as fast as their developers.
meager fog
as long as eventually they all use circuitpython
also now they can add other cool sensors, like BMPs, or air quality sensors
solar whale
@meager fog I'll update the co-processor guide tomorrow and create a pr to add the second piece to the miniesptool_esp8266program .py example
meager fog
thanks!
ruby atlas
Speaking of users, I haven't updated my Homeasisstant in forever. I need to look at new tablets for the home automation controllers as the ancient ones are stuck on android 4.4.
meager fog
i have to get energy to work on the socket stuff
@solar whale btw @gentle bronze is working on the OLED/i2c thing now
should not be a big challenge to fix
ruby atlas
i've been recharging my energy by not working on billable stuff for clients. i need to fire one or two more in 2019.
solar whale
@ruby atlas congatulations o getting the ESP32 AT up and running -- have fun!

yah that was fast
ruby atlas
It was stupid easy with your pinout notes.
meager fog
which is good, makes me feel confident-er about the code
ruby atlas
And the fact that I can read code.
Way easier than the Pixelbuf I'm doing 😃
And easier than the changes to the FFT example even 😃
meager fog
loll
solar whale
good night all 💤

I ❤ the FFT stuff. It lets me know when a song sounds good only because it's mixed loudly.

Also was fun to watch the Weekly meeting audio to see who'se voices landed in what frequency bands.
(i have a mixer on my desk with a USB interface, 2 more audio interfaces, and a DAC on my system's optical out, it may be overkill)

@meager fog
I have a question about sensors generic in circuitpython.
When i read DHT i think more of a low quality sensor. That's about i had worked now 32 years in industrial and building automation. So we/i use sensors which are from a hihger quality, like BOSCH or VEML sensors. You have some of them in the Adafruit shop when i remember that right
So will these sensors and others also ported to circuitpython or there are sensors which are alraedy ported to circuitpython?
I don't use circuitpython, in my way i use ansi-c, C sharp and C++. I ask because a friend of mine will do some tests in circuitpython and he is sensor guru too ;-).
meager fog
hi all our sensors are ported to python/circuitpython
you can see them here https://github.com/adafruit/Adafruit_CircuitPython_Bundle/tree/master/libraries/drivers
Bosch, Si7021, SHT3x are all good quality sensors
mint remnant
Thank You @meager fog . I will take a deep look in that to find the right drivers.
->Bosch, Si7021, SHT3x are all good quality sensors
oops moment please
Thats right so far the PCB layouts are done in good way. There are breakout boards out there with temperature issues because the regulator is, as an example, to short placed to the sensor, or the regulator is too small and many other things can happen while development.
So far i have seen has Adafruit done a very good job to have an eye on that specific issue. Hold up that good work.

gdb so drunk
(gdb) break clock51.rs:241
Breakpoint 1 at 0x43de: file /home/paul/rust/atsamd/hal/src/clock51.rs, line 483.
(gdb)
now it's doing this
Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x6686
I think because the openocd.cfg has gdb_memory_map disable in it

@meager fog is there a problem with travis -- submitted PR for miniesptool, but travis is just "queued"
nevermind - travis is happy now -- that is all that matters 😉
solar whale
@meager fog is the image support in framebuf/ssd1306 only for linux? looking for module PIL
lime trellis
@solar whale @meager fog got around to trying miniesptool with my custom SAMD51/ESP32 board. It worked great after only some minor adjustments! I'll submit a PR after some validation.
thanks for all your hard work on that. It made things much easier!
solar whale
You are welcome -- glad to hear you have it up and running.
look forward to hearing more about your implementation
manic glacierBOT
lime trellis
@solar whale it's still quite hacky, but you can take a look at https://github.com/maholli/SAM32/blob/master/firmware/esp32_firmware/main.py
I also have a working "UART bridge" mode for circuitpython that allows you to interact with the esp32 REPL, which is shown in example.py in the parent directory
solar whale
@lime trellis so you are running micropython on the ESP32 -- not just the AT Firmware. Nice,
lime trellis
yep! circuitpython on the SAMD51 and micropython on the ESP32
solar whale
interesting -- I may have to try that on the particle_argon. I had not even thought about that.
lime trellis
I'm now working on the low-level C necessary for a camera module in CP. I'm wanting to have an OVM9724 attachment board:
Let me know if you run into any snags! Hadn't seen the particle argon before, but it's similar to my "SAM32" board linked above.
solar whale
Thanks -- lots of new possibilities
lime trellis
@solar whale I'm about ready to rev the SAM32 to add some CPX-inspired features. let me know if you're interested and I could send a couple boards your way.
solar whale
@lime trellis I always like checking out new boards -- I'll be happy to be a tester.
lime trellis
awesome! I'll reach out when I have a few assembled
solar whale
Thanks!
lime trellis
ping me if you (or anyone you know) would be interested in helping with the camera work. Should be a VERY unique capability for CP!
solar whale
I'm not sure how much I can help - but would be happy to try. Do you have more information about how it is going to work and what is needed in terms of new SW?
lime trellis
its leveraging the "parallel capture controller" capability of the atmel SAMD51. Here's a nice app-note by FTDI on the interface: https://www.ftdichip.com/Support/Documents/TechnicalNotes/TN_158_What_Is_The_Camera_Parallel_Interface.pdf
meager fog
we've got some code for the PCC
lime trellis
@meager fog yep that's the plan
meager fog
its in arduinoese - should be portable 😃
lime trellis
😮 oh boy!
lime trellis
ah! once again your timing is perfect
meager fog
you can ignore the ili9341/spi stuff
you need one i2c device for config, and then of course the PCC
warning you need to buffer the full image
so pick a camera with a low res output
320x240 x 2bytecolor = 150KB
@solar whale just loggin' in now
lime trellis
Wow buffering the whole thing?
solar whale
@meager fog I was trying the image stuff but is it only for Linux?
meager fog
the pil stuff? yes
its for linux/desktop use only
thats tested tho, if you wanna try it on our nrf52840
you can test the i2c fix and the examples that are not linuxy
solar whale
I 've been testing them on the particle_argon -- ssd1306_framebuftest works fine now
lime trellis
hmmm I'll have to dig a bit more. I wanted to use the direct-memory access and just shuttle the image off as it came in.
Thank you for the link to get started!!
lime trellis
👍 I'll let you know how it goes
solar whale
@meager fog on the argon I get a brief flash of random pixels at start, but then the demo runs fine.
meager fog
@solar whale thats not surprisng
when you turn it on, there may be RAM still
@lime trellis cool! yeah we sorta recommend the OV7670 i think thats the demo, its very common
marble hornet
@lime trellis looks like cool stuff!
meager fog
each camera is a little different
@solar whale if ya can review https://github.com/adafruit/Adafruit_CircuitPython_SSD1306/pull/17 and https://github.com/adafruit/Adafruit_CircuitPython_framebuf/pull/8
ill do a re-release
solar whale
ok -- will do
solar whale
@meager fog sure -- go ahead with miniesp - I'll update the guide this afternoon
meager fog
roy, the updater code
ruby atlas
google's not helpful: "Did you mean: minidsp" 😃
solar whale
@meager fog is there anything I can do to test image on the nrf52840?
I can try them on a Raspberry Pi
or do you just want me to look over the code and approve?
meager fog
@solar whale nah, @prime flower has done the linux-side testing
@umbral dagger hey given that ssd1306 is working again, wanna re-try your feather project with the oled?
solar whale
ok -- looks good to me and it doesn't break anything!
meager fog
cool - re-released minitool
solar whale
approved framebuf and ssd1306
meager fog
thanks, brent will take a look too
solar whale
Great!
umbral dagger
@meager fog Will do
solar whale
off to do errands -- back later
lime trellis
has anyone written CP code to mount an SD card alongside the SAMD flash?
tawny creek
@lime trellis sounds new to me. you mean when you plug in the board, it mounts along whatever CP mounts as CIRCUITPY? (built in or spi flash)
@lime trellis also cool project! was thinking of using an esp32 beyond just wifi stuff,, seems powerful enough
lime trellis
@tawny creek yeah that's what I was imagining. I could have swore I saw something like that... maybe it was mircopython?
ah! I think I saw it on the pyboard: http://wiki.micropython.org/pyb-SD
tawny creek
@lime trellis first i heard of this, cool idea!
lime trellis
yeah I may end up writing one for CP since I'm always going back and forth for a datalogging project. I'll post if I do
meager fog
@lime trellis we dont (yet) expose the SD as a separate MSD device
its not entierly unpurposeful, because you can't write to it if so
and most people i think would want to
lime trellis
@meager fog yes, understood. I just find it helpful for accessing data files or loading .mpy files
meager fog
may be something we add after tinyusb is all sorted - since we'll have more flex
why is mpy on SD not SPI flash?
SPI flash is fsater 😃
lime trellis
very true! but the adalogger boards don't have SPI flash 😃
lime trellis
yep 😃 the students using this datalogging setup haven't complained, but I'm now supplying sd card readers in order for them to easily get their data.
meager fog
that works!
exotic pumice
So has anyone used openocd on metro m4 before or do y'all just use jlink?
idle owl
Most of us use JLink
exotic pumice
I might have to invest in one of those then
idle owl
There's the JLink EDU Mini that's super affordable as long as you're using it for personal purposes.
exotic pumice
Yeah
hazy gust
@exotic pumice I read about openocd after you talked about it yesterday, interesting rabbit hole to go down 😃
exotic pumice
@earnest turtle 😎
Cool, glad I could be of interest lol
Yeah I can't figure out why the breakpoints don't work
I shouldn't need the reset line for that should I? I read that you only need it sometimes and I wasn't sure what the "sometimes" fully entailed
I think it's more likely due to the fact that samd51 is barely supported at all. I've used breakpoints before on stm32 with no reset line.
solar whale
Happy cat! Via blinka!
hazy gust
feather OLED sold out :/
solar whale
that is on a PiOLED https://www.adafruit.com/product/3527
hazy gust
yep, cool for sure
solar whale
@meager fog a guide "style" question - -- for something like miniesptool do you prefer to instruct the user to do it via "code.py" and never use the REPL . I alway use the REPL to just import miniesptool_esp8266program but It looks liek you tend to avoid the REPL in the guide. I guess that avoids explaing how to use the REPL - but it is a little scary having the miniesptool execute from code.py 😬 :
I'm assuming somone doing this know how to use the REPL
tawny creek
just a curiosity, would it be possible to run say the AT firmware on a single core on the esp32 and then have the other core run seesaw? @solar whale @meager fog
solar whale
"possible" is a pretty open term 😉 Actually, I have no idea -- would have to do some research.
tawny creek
not sure how much the esp needs both cores to do the wifi stuff / bluetooth
idle owl
@solar whale Most guides use the REPL and then include example code at the end
Could be different for that guide.
solar whale
@idle owl That is what I am used to -- I'm looking at https://learn.adafruit.com/adding-a-wifi-co-processor-to-circuitpython-esp8266-esp32/firmware-upload
under "Program Directly"
idle owl
Ladyada is AFK, so if you're unsure you can wait, but I'd say use your best judgement, and if it makes sense to run it from the REPL instead, explain that. You can link to the Welcome to CircuitPython guide REPL pages instead of explaining it
solar whale
np -- no rush on this. I make a stab at it and it can easily be updated.
idle owl
That's what we do in every library/sensor guide. There's using the REPL in Mu and "Advanced Usage" on that page, you could link to all of them if you wanted to.
True!
solar whale
Thanks!
ruby atlas
I don't suppose anyone can think of a circuitpython builtin API that takes an optional callable (callback) that the C code might invoke? (I'm searching the source for examples still).
ruby lake
Hm, I need to track down this m4 dac noise, might be a chip problem
tulip sleet
@ruby atlas I don't think there's such an example, at least in CircuitPython. There are interrupt handlers in MicroPython.
ruby atlas
@tulip sleet yeah, that's what I found, plus the Timer stuff.
Will look at both.
looks like the code in timer.c should help me at leas test this.
(ports/stm32/timer.c)
manic glacierBOT
ruby atlas
@tulip sleet can you think of any reason I might need to use either gc_lock or mp_sched_lock (on those platforms where mp_sched_lock is needed).
mp_call_function_1 turned out to be the answer 😃
tulip sleet
I have never used it
ruby atlas
I think locking GC and/or the scheduler only matters for interrupt driven callbacks like the timer.
This is directly triggered by python code calling a c module that calls a python callback.
tulip sleet
so you're calling from the native C code to subclass Python code. Or is a callback?
got it
ruby atlas
the subclass approach... broken in too many ways currently.
tulip sleet
yes, native classes aren't really meant to be subclassed, I think. I should look that up more thoroughly
ruby atlas
It doesn't seem like it would be hard to make possible.
So the plan is now to have a little bit more code in C that the neopixel and dotstar classes use to return a pixelbuf object that's configured appropriately.
I'm thinking of adding some magic to allow passing neopixel_write object in directly with appropriate extra args so that it can bypass executing a python function to get back to neopixel_write.
ruby atlas
Yes.
I was thinking this might be the initializer for a Neopixel buffer: pb = pixelbuf.PixelBuf(32, buf, byteorder=pixelbuf.GRB, bpp=3, rawbuf=rawbuf, write_function=neopixel_write, write_function_args=(pin,), write_data=pixelbuf.WRITE_BYTES)
A dotstar one might then be:
The current behaviour is to pass the write function the pixelbuf object.
hence the flag to change the mode.
tulip sleet
I'm still curious about why the subclassing approach is working better than having a PixelBuf as an attribute of NeoPixel or DotStar.
you said it was less code
ruby atlas
Performance of index operations is why I tried in the first place.
I don't want to have to go through python intermediaries to do pixel assignment.
tulip sleet
ah, I see, so those are done direclty in C. Yes, it makes sense that's the main speedup. I've always found indexing slow in Python, even on "regular" computers
ruby atlas
yeah, for example, with pb[0:32] = [(32, n, n) for n in range(32)] it uses the C code to make it much faster.
I wonder if I can expose setitem etc in the C class and then assign those to properties on a Neopixel/Dotstar composed object and have the same performance gain.
In theory that should work, I should try that.
I guess I'll need to benchmark 😃
Oh hmmm, subscr is both setitem and getitem.
However, if I split it up and expose the appropriate parts in STATIC const mp_rom_map_elem_t pixelbuf_pixelbuf_locals_dict_table it should be possible to do something like:
__setitem__ = pixelbuf.Pixelbuf.__setitem__
(Assuming I don't need to rename it).
tulip sleet
Sounds promising! There are gotcha shortcuts as you found in the low-level stuff. I don't have a lot of advice to offer here because you're doing things we generally haven't had to do yet.
tulip sleet
Yay yes. I would also say not to over-generalize the code if there's not a real use case other than neopixels and dotstars. If those need to be hardcoded I'm not sure that's so terrible in order to get performance.
Also the brightness != 1.0 case
ruby atlas
Brightness != 1.0 is the main use case of this code.
tulip sleet
got ti
ruby atlas
And why I started in the first place.
My tests are all using 0.3
I should check if 1.0 is the same speed.
yep
and my eyes!
they have spots.
tulip sleet
i do a lot of nepixel testing with them facing upside down 😃
ruby atlas
i need to 3d print more covers.
white plastic, 1mm thick
the dotstars featherwing should be known as the supernova featherwing.
tulip sleet
could you just use opaque white sheet acrylic?
ruby atlas
i could, but that means finding acrylic.
3d printing means 5 minutes of openscad
and ~10 min of print time
going to a store that might have acrylic would be longer.
tulip sleet
i still don't have a 3d printer - I'm into subtractive technology 😃 drilling holes in things, sawing, etc.
tulip sleet
i don't have room for a proper workbench for that stuff. sorry to fade off, it's late and I got to a good stopping point with BLE for tonight
looking forward to your end results! good night!
ruby atlas
good night! i'm also stopping for the night now that I made it "go" and have real thoughts on how to move ahead.
tulip sleet
it's always good to stop when something works instead of not. don't try the next thing
ruby atlas
Exactly!
raven canopy
Coming in at the end, of course. @tulip sleet, check out Paul Sellers "newest" version of his workbench. Can be made quite small (like 24"x18ish) and still function well.
he mentions as he's on year 2 of building one. all-hand-tool construction takes time and even more motivation 😆
