@prime cove btw if you've written a lib for the 8563, please consider submitting it to the community bundle! https://github.com/adafruit/CircuitPython_Community_Bundle
prime cove
That's the plan! Just ran into that problem while getting everything in place.
onyx hinge
I know how that goes
prime cove
@onyx hinge I PM'd you with an unrelated question as well when you get a moment.
onyx hinge
@prime cove just curious, is 8563 cheaper ? more available ? than other RTCs?
prime cove
I think the pricing is fairly similar, though I don't know how that extends to distributor quantities. I think the difference is the the 8523 has the integrated battery switchover stuff.

Is there a way to handle dropped packets/connection issues in Circuit Python? I've got a PyPortal that hangs on WiFi requests.
(asking here over the help channel as I'm guessing there is no interrupt type thing for WiFi and it would have to be implemented in CP)
solar whale
@tired cloak you can wrap the request in a try/except ``` try:
print("Fetching json from", DATA_SOURCE)
response = wifi.get(DATA_SOURCE)
print(response.json())
value = response.json()
for key in DATA_LOCATION:
value = value[key]
print(value)
response.close()
except (ValueError, RuntimeError) as e:
print("Failed to get data, retrying\n", e)
wifi.reset()
continue
@solar whale thanks, there already is a try/except ... using the weather station code in one of the Adabox examples... it doesn't trigger the exception, but keeps waiting for the response.
(Which, even hours later, never comes.)
prime cove
"Disable socket, wiznet5k and network modules. They will be removed in 7.x in favor of networking libraries." For reference, what specifically are the networking libraries? And will the wiznet chip still be supported by them?
slender iron
@slender iron you have talked about re-using the M.2 connectors before, I see Sparkfun has now implement such a reuse what do you think of what they have done, will you guys support this 'Micromod' standard especially with many of their cores capable of supporting CP?
@blissful palm I've ordered some. only the SAMD51 core will run CircuitPython. designing pinouts is tough and this one looks reasonable
slender iron
@solar whale thanks, there already is a try/except ... using the weather station code in one of the Adabox examples... it doesn't trigger the exception, but keeps waiting for the response.
@tired cloak can you ctrl-c when it's hung? if so, please post the traceback
"Disable socket, wiznet5k and network modules. They will be removed in 7.x in favor of networking libraries." For reference, what specifically are the networking libraries? And will the wiznet chip still be supported by them?
@prime cove for the pyportal it is the ESP32SPI library, nothing native. For the -S2 the new modules arewifi,sslandsocketpool. The wiznet won't be supported by the core but we have a library for it already.
prime cove
Ah I see, so its just being moved out from the core than completely dropped. Thanks!

@onyx hinge are you using the idf in circuitpython for TWAI?
onyx hinge
@slender iron yeah e.g., esp_err_t result = twai_driver_install(&g_config, &t_config, &f_config);

same idf version, I'm using the one I have in my circuitpython clone

Hello. I just upgraded from 5.3.1 to 6.0.0-rc0 and my code.py took me straight to the hard fault handler. I'm making a 400kHz i2c, using the CLUE's magnetometer to read into a ulab array. Any tips on where to look first? You are in safe mode: something unanticipated happened. CircuitPython core code crashed hard. Whoops! Crash into the HardFault_Handler.
slender iron
@simple pulsar please file an issue with the exact code so we can repro
the way to debug is to repro with a debugger connected and then check out the backtrace
manic glacierBOT

I'll comments out a few bits to see if i can pinpoint it a little and reduce the code size to reproduce

@slender iron will do, at work now, but chances are it'll be hung when I'm done!
onyx hinge
the filter values being sent in are different but they should read back as themselves
onyx hinge
sure, I can do that.
though -- the value in cpy is TWAI_FILTER_CONFIG_ACCEPT_ALL which should be accepted!
onyx hinge
I (334) TWAI Self Test: f_config.acceptance_mask = 0xffffffff
I (334) TWAI Self Test: f_config.single_filter = 0x00000001

onyx hinge
there are some xSemaphore and xTask calls but that's it
unless things can happen before app_main
onyx hinge
🤷 help me learn how to answer that
simple pulsar
I may have found something else, ulab blows up if I try and retrieve an array element with a float
onyx hinge
(I think it's less likely it's clocks, because transmission works. reception works, if you pick a message that gets past the filter. but setting the filter isn't working. my gut tells me if clocks were wrong it just wouldn't transmit in the first place)
simple pulsar
Is that a known issue, I'm just about to rummage through github
onyx hinge
not known to me.
simple pulsar
Would the issue go in adafruit/circuitpython or in ulab's repo?
onyx hinge
on the one hand it is unlikely the bug is in circuitpython. on the other hand, if you haven't reproduced it in ulab-with-micropython it may be the case that the issue does not occur there.
slender iron
@onyx hinge true. reading back the filter getting 5a feels like a memory access error or sync issue
@onyx hinge looks like the filter addresses are shared with the buffer
are you reading it in reset mode?
(reading 20.4.1 in the technical reference)
onyx hinge
yes, or at any rate in both pieces of code this is after twai_driver_install and before twai_start.
slender iron
pulls up the idf
onyx hinge
so it should be the same HW state, and I went and read the code of both and it's twai_start that puts it out of reset mode
mode_reg = 0x0000000b on both
onyx hinge
[did 3 people just correct the same typo within minutes of each other?]
slender iron
yup, is the spanish contributing to circuitpython stream going? 🙂
onyx hinge
oh no, I hope nobody is educating people how to edit translations manually.
onyx hinge
@slender iron how do you suggest I continue to dig into this? I did verify that if I manually assign those registers, they still read back 0x5a
I verified the example code and my code have the TWAI peripheral at the same address
slender iron
what is the bigger problem? does the filter not work?
onyx hinge
That's right, regardless of what filter I try to set, it seems like only the all-bits-set ID gets received
at least, 0, and 0x555 (or something like that) do NOT get received
slender iron
@silver tapir we're just wondering if they are teaching to do translation changes outside of weblate
silver tapir
Oh, I see.
slender iron
@onyx hinge hrm, but it works in the example. another thing to check is the kconfig stuff
onyx hinge
there's nothing explicitly TWAI in the sdkconfig file
onyx hinge
https://gist.github.com/6d18b30dd7448d73d3f3057500fae7d7 is the sdkconfig it generated with menuconfig
I don't know if I can diff them or something but .. that's not likely to be a small diff
slender iron
menuconfig for the example?
onyx hinge
yes, it has you run a menuconfig to set the pins to use
slender iron
the circuitpython sdkconfig ends up in the build-* folder
onyx hinge
config EXAMPLE_TX_GPIO_NUM
int "TX GPIO number"
``` etcI mean, diff between what circuitpython has and what this example has
but it's probably totally different
slender iron
it's worth a try I think
onyx hinge
CONFIG_ESP32S2_DATA_CACHE_0KB=y
onyx hinge
see ya later
TWAI controller runs from APB_CLK (page 40 of technical reference v0.6) and twai_driver_install calls periph_module_enable(PERIPH_TWAI_MODULE); //Enable APB CLK to TWAI peripheral
afk too

Comment about using weblate transmitted to the folks of E.C.
It seems they did a pull request in the live-stream, and I guess that a translation was easy enough. Maybe some of the people watching went and did the same.

need to add some SPI flash too

@cursive condor have you gotten repl for other boards? What is going wrong?

yep REPL is working great with the same cable and a circuit playground
tulip sleet
what's the name of the .uf2 you're trying to upload, and do you see a ...BOOT drive when double-clicking? And what terminal program are you using on what OS?
cursive condor
and I got it working on a linux box ...
so the problem is with my windows 8.1 box
tulip sleet
windows 8 needs drivers, and the driver package hasn't been updated yet for new boards. THis is your opportunity to upgrade to windows 10 🙂
i have successfully upgraded for free from below windows 10 using the Windows Media Creation tool. As long as your 8.1 is properly licensed, it appears to work. I have done this a dozen times on various Dell boxes; haven't tried it on others
cursive condor
well ... I don't want to upgrade right now. so i'll go with the linux box for testing with REPL... no big deal (and I think I see a solution with an arduino lying around)
tulip sleet
no problem, I am just trying to reduce my work load of upgrading the driver package 😉

I used it to have a serial terminal on foneras to configure open-WRT IIRC
and I see TX and RX pins on the matrixportal, that should do the trick

I saw a couple of people talking about how to checkout a PR and I actually didn't know how to do it either before this week. Anyway... while you can do the GIT method git fetch adafruit pull/3580/head:3580-Test (Assuming you have a remote called adafruit) there is also a new (ish) github cli and the command is gh pr checkout 3580 which I think is lovely and almost pythonic in how readable it is. It does other Githuby things, as well so if that interests you.... https://cli.github.com/

I was thinking to extend my personal build of circuitpython to make a method that takes in two hex values. First is target color, second is source or vice versa. And it will swap the color out like the palette does for that instance of the colorconverter. that is REALLY unique maybe to just what I am doing though
Not worth it to PR correct?
especially if its already pushing memory limits haha

@slender iron I have a workaround for my can/twai filters problem, but it doesn't make much sense and it's inside the esp-idf.

@blissful pollen Under WSL2 I made some small changes to the various Makefile to allow flashing without leaving WSL2. For example for the nrf port I added the following target:

nrfjprog.exe --erasepage $(BOOT_SETTING_ADDR) -f $(MCU_VARIANT)
nrfjprog.exe --memwr $(BOOT_SETTING_ADDR) --val 0x00000001 -f $(MCU_VARIANT)
nrfjprog.exe --reset -f $(MCU_VARIANT)
This only requires that I have nrfjprog.exe in my Windows path.

@onyx hinge I don't have any insight. We could turn off -Os if needed

I don't think we want -O0 😦
slender iron
you could use a pragma to change just the function you think matters
onyx hinge
yes but it's in esp-idf -- are we carrying a modified version of esp-idf at the moment?
onyx hinge
yeah I think that's gotta be the next step
slender iron
we could also have a forked version
I think I found an issue with mixing DMA and non-DMA with SPI
onyx hinge
it's either a bug in the xtensa compiler OR it's a bug in this function that is almost too simple to have a bug OR it's a spooky bug that moves around when only this function's optimization is off
OR something I'll slap my forehead for later, but that's always a possibility

Here is the notes document for Monday’s CircuitPython Weekly meeting. It is at the normal time of 11am Pacific / 2pm Eastern here on Discord.
@slender iron There is a 50/50 chance that I got it in the wrong direction, but maybe you want to update the next meeting announcement and put a warning.
Europe will move from DST (Daylight Saving Time) to Winter time on October 25. As always, the US will end DST a week after Europe on November 1st.
So for one week only, the usual time of the meeting will be one hour later(?) for European. And the next week it should go back to normal.
Yeah, and maybe a warning for the next one too, as not everybody practice DST...

@thorny jay this look right? https://everytimezone.com/?t=5f961180,438

<@&356864093652516868> Check your time for the next meeting here: https://everytimezone.com/?t=5f961180,438 The US hasn't switched daylight savings time yet so it'll likely be a different time. Thanks to @thorny jay for the heads up.

Hi, I'm a beginner, I know the basics of python, could I help with something related to programming?
manic glacierBOT
mental nexus
One random issue to report using the Saola ESP32-S2 development board. I had GPIO pin 0 connected to the input of an LCD display (while checking for ParallelBus support) and whenever GPIO 0 (zero) was connected, then CircuitPython would not boot. Perhaps this pin 0 (zero) is used for the boot sequencing. I seem to recall something about this on Scott’s livestream but don’t recall when, so I thought I would document it here. The schematic shows GPIO0 connected to “IO0_Auto” which is connected to RTS through a transistor and shows a truth table related to the “auto program”. Anyway, just a warning for anyone that sees strange behavior when using GPIO0.
crimson ferry
Yes, GPIO0 is special and used to select boot mode https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/dfu.html?highlight=gpio0

sacred socket
Where is the documentation for the CircuitPython libraries? I spend hours searching Adafruit/Github/Google looking for ways to something that would only take a few minutes if I had good documentation of the libraries and their user accessible functions/methods. I'm working on the Clue. I want to use it inverted to display info. I don't think simple_text_display supports that. I know in "graphics mode" the display can be rotated.
lone axle
@sacred socket I usually get to the docs by going to the Github repo for the library and then there is a link along with some of the other "badges" at the top of the readme:
if you click that it will take you to the docs page for that library
sacred socket
I'll check that out.
lone axle
do I understand correctly your intion is to rotate the screen by 90 degrees?
sacred socket
180\
lone axle
The core documentation for Display object here will be helpful too: https://circuitpython.readthedocs.io/en/latest/shared-bindings/displayio/index.html#displayio.Display.rotation
I think you should be able to do something like:
board.DISPLAY.rotation = 180
I've been on some o those github pages. I think I missed the index link at the bottom of the page.
That line look familiar. Thanks for the guidance.
And the readthedocs pages I landed on were less understandable the the github pages.
modest hazel
Does anyone know a good way to scrape the library, class, attribute, and method/function names from the docs or github for CiruitPython? I'd like to include them in the autoCompleter for the IDE I'm building.
onyx hinge
@modest hazel you want to use the ".pyi" files that are generated during the build process ("make stubs" in the top level directory). I don't know what the plan/story is for having those be available to intelligent editors, but the idea is to work with anything that understands .pyi files, they are a standard in Python.

opal crystal
I just discovered that when I build CircuitPython for SAMD51 with DEBUG=1, it optimizes out all calls to raise_deinited_error(). I’ve narrowed it down to the -Og flag. Anyone familiar enough with GCC (GNU Arm Embedded Toolchain 9-2020-q2-update 9.3.1 20200408) optimization settings to have a clue why? It seems kinda strange, shouldn’t -Og optimize less than the default -Os?
crimson ferry
Does main run on every reload?
opal crystal
No, it only runs once. Reloads are the infinite loop at the end of main().
crimson ferry
Ah, thanks, that makes sense... was wondering why reload doesn't get my board to a clean state and I have to power cycle
opal crystal
The reason is that certain things such as displays need to be kept working over a reload, and then there are bugs – I’m currently debugging some.
tulip sleet
@opal crystal I have no explanation for -Og messing with raise_deinited_error(). The latter is declared NORETURN (indirectly), but that shouldn't make a difference. You might try disabling -flto to see if it stops the spurious optimization. You could look at the assembly output to see if it's truly disappearing.
arm-none-eabi-objdump -D -Mforce-thumb firmware.elf will generate an assembly listing
i've had some weird experiences with -Og myself, thought I can't remember the details right now.
also i've found it useful to disable inlining when debugging
some of the time
opal crystal
OK, will check -flto. I did check the disassembly (in gdb) – it’s specifically the calls to the various check_for_deinit() that disappear. Apparently the optimizer thinks these do nothing – when I add some mp_hal_stdout_tx_str() calls to either check_for_deinit or raise_deinited_error, they reappear. raise_deinited_error itself still exists in the code and works if I jump to it in the debugger.
tulip sleet
that's upsetting; it's thinking a noreturn has not side effects, which is odd
it's like it's not handling transitive noreturn correctly
opal crystal
I tried adding an explicit NORETURN but that didn’t change anything.
tulip sleet
i wonder if the compiler thinks it is proving that it can never be called
I looked in the gcc bug tracker but I don't see anything recent
opal crystal
Removing -flto -flto-partition=none (but keeping -Og) also makes it work correctly, keeping the check_for_deinit() calls. Let’s see which one turns out more convenient for debugging…
Thanks for the suggestion.
tulip sleet
turning off lto makes the compiles a lot faster 🙂
opal crystal
And the code a lot larger, it barely fits now.
tulip sleet
and then turning off inlining will save on breakpoints, because there aren't multiple copies of a routine. (Turning off inlining should also bring the code size back down somewhat.)
opal crystal
OK, good to know.
tulip sleet
and if you tab-complete in gdb, you won't see all the ".123" style suffixes

You can determine the wiring from the call to ESP32() in that program. If you run that program, and then use the Adafruit Bluefruit Connect app, and choose the UART page, you should see it echo.

quest me
meager fog
neopixels for esp32(s2) work amazing in circuitpython
but NOT in arduino
because we dont use the RMT periph
folks keep asking us to use RMT in arduino and im like "plz PR" and noboby PRs
ionic elk
You want em for arduino?
ionic elk
im on it
ionic elk
I gotta work on my Arduino chops again
I'm a little more up to speed since I gotta use them for my uncanney eyes fork
actually... maybe I should port it to ESP32-S2?? 🤔

Imagine being summoned by the Adagods for a quest 😎

@ionic elk here's some inspiration https://github.com/FastLED/FastLED/tree/master/platforms/esp/32
idle owl
@gilded cradle Hey do you happen to have calipers and a 1.3" Pi MiniTFT? I need to know what size the mounting holes are. It's unclear in Eagle.
gilded cradle
Yeah, let me check. You mean the breakout?
idle owl
It's a little display with half of a Pi header on it.
Hold on I can link to the product.
gilded cradle
Oh pi mini tft. Let me dig it out.
idle owl
This one: https://www.adafruit.com/product/4484
gilded cradle
Found it...
gilded cradle
it looks about 0.9 inches. Is it not in eagle though?
idle owl
Would it be listed somewhere? Maybe I don't know how to find that info.
gilded cradle
Hmm, it doesn't look like there's a fab print onthe product guide
idle owl
That's what I'm working on 😄
I couldn't tell in Eagle what was the mounting hole and what was indicator information.
gilded cradle
Oh, ok. That makes more sense.
idle owl
Thank you!
gilded cradle
yw
tulip sleet
@gilded cradle is it 0.09? 0.9" seems large 🙂
gilded cradle
They're 0.9" apart. I think I misunderstood the question. Let me re-check...
tulip sleet
either is plausble. Both measurements are certainly useful
gilded cradle
@idle owl if you meant hole diameter, they're measuring at 0.1135 inches for me.
idle owl
I did mean diameter. I'll go back and look again at what comes out to that much. Thank you again!
idle owl
Yeah, I went with inches. Because there are other dims that are more even in imperial.
gilded cradle
Oh, ok
idle owl
0.12 inches fits the blue outline on the mounting hole in Eagle, so I'm going with that. There's only 2 digits of precision.
gilded cradle
Yeah, we're putting a part that's in imperial onto a board that's measured in metric.
idle owl
Right.
gilded cradle
So it's an adapter of sorts.
idle owl
Fixed. Thank you.
gilded cradle

ionic elk
@slender iron are you online?
slender iron
yup, in a meeting though
ionic elk
Well, whenever you get a sec, I was wondering what the difference was between the shared-bindings functions for SPI and UART - UART's read functions are WAY simpler, and I was wondering if it's possible to use that syntax by default or whether it depends on something else (like stream)
they don't do arg parsing or anything
slender iron
right, uart uses the stream protocol to do most of it
meager fog
@idle owl you can find eagle drill sizes with the (i) tool
the drill may be in inches or mm, based on what the file was saved as - you can figure which!
@idle owl make sure holes layer is on -
idle owl
@meager fog Oh... maybe the layer wasn't on. I tried using that and wasn't getting anything useful.
blissful pollen
@slender iron no rush on an answer but working on busdevice and is it better to submit a PR earlier or wait? I've got most of I2CDevice done (not polished) and still have SPI to do
slender iron
earlier is always better. draft status is handy for it
ionic elk
@blissful pollen is busdevice for devices as peripherals?
because I'm working on SPIPeripheral at the moment
(IE SPI slave support)
blissful pollen
I'd have to check with @slender iron to be certain. I saw people were talking about the busdevice python library and it had been talked about being moved to the core. It more just lets you use it with "with" to take advantage of__enter__ and exit to lock the I2C bus for example
idle owl
@ionic elk It's the Adafruit CircuitPython Bus Device library moved to the core.
ionic elk
Oh gotcha, nothing to do with slave/peripheral mode then
blissful pollen
So now that i'm curious what's the SPI peripheral mode do?
manic glacierBOT
ionic elk
@blissful pollen it allows you to set up circuitpython as an SPI peripheral/slave, so it responds to commands from a host/master device.

Please add your hug reports and status updates even if you’ll be attending the meeting - it’s super helpful! If you are unable to attend but would still like to include updates, feel free to include them in the notes and we’ll read them off during the meeting. Hope to see you there! <@&356864093652516868> https://docs.google.com/document/d/1P6H-XeIR68ckTJ6Qh26_rQR-8jjx2X4vtz4-OaripvY/edit
ionic elk
Oh dang it I missed the meeting, I'm sorry. I completely flaked, not in the right mindset yet from the last week.
@slender iron when we talked about crypto, were you thinking of just implementing AESIO on STM32/ESP32 then?
or did you have anything else in mind?
idle owl
@tidal kiln What's up?
tulip sleet
@idle owl do you know who made this graphic? It's in the Airlift breakout guide. I need to edit it to add BLE info. Tnx
idle owl
@ionic elk No worries, we read off your stuff. It takes time to get back to things.
@tulip sleet No idea, I think it's someone outside of Adafruit who was making them. Ping Limor I guess.
slender iron
@ionic elk you should definitely start with aesio. I had forgotten it was added last time we talked
it's not a priority though
ionic elk
Sure. My top thing right now is getting the RMT into Arduino as per Ladyada's request, along with wrapping up old PRs
slender iron
the f1 and 1050 old PRs?
ionic elk
after that though my priority list has TouchIO for STM32 and then it's a bit open ended
slender iron
what's left on them?
ionic elk
F1 needs a simple fix but lots of testing
slender iron
-S2 work is more important than STM32
ionic elk
Mark Olsson figured it out, it's an interrupt thing related to FS USB
tidal kiln
@idle owl seeing possible confusion when installing CP libs - files vs. folders. like when theres a library folder foo with foo.mpy, foo_helper.mpy, foo_someotherfoo.mpy, etc. sometimes only foo.mpy is getting copied over, instead of entire folder when the guide instruction say you need library foo
slender iron
k, if you can do a quick fix and then we can merge that's ok
ionic elk
My OG plan was to do TouchIO for ESP32-S2 but I saw Microdev was already on that
slender iron
not worth spending a lot of time on though
ionic elk
Do you have other stuff you'd like ASAP for ESP32-S2?
slender iron
arduino neopixel is top priority
idle owl
@tidal kiln I thought we were pretty clear about when it's a folder and when it's a file.... What do you suggest?
slender iron
then networking API expanding and fixing would be good
we could add the socket APIs to be a server and do UDP
ionic elk
ok, I'll do some reading about that
idle owl
@tidal kiln e.g. the page I'm working on:
Is how I do it, I thought. Perhaps I haven't been consistent. Or maybe it's different when it's a huge list and I don't specify for each one.
tidal kiln
updating guide here:
https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-libraries#installing-the-circuitpython-library-bundle-2977975-5
to be more explicit about copying entire folder. i'm willing to do the update if you want.
tidal kiln
i think i'm dealing with a case where only adafruit_io.mpy was copied over - not the entire adafruit_io folder
idle owl
Oh yeah, that's not clear at all. 😕
@tidal kiln Updating the main guide is good, but that page should also be made clearer. like neopixel.mpy and adafruit_io/ with the .mpy and / added.
Might still not be enough, but it's going to help someone I would think.
tidal kiln
yep. having the guides be more verbose and say "folder" etc. would be great, but it's pretty hit or miss.
ok, i'll update the main guide and let you know so you can review.
idle owl
Cheers. Appreciate it.
tame hatch
Helloooo! I have a question, but I'm not sure what the right channel to ask it may be. I have a Matrix Portal that I may or may not have gotten from a recent adabox...
I'm reprogramming it using circuitpython, and am registering button presses from the hardware buttons
are those buttons also available via the gpio pins? or are they just a dedicated thing?
tidal kiln
idle owl
@tidal kiln I will also mention the issue to Anne since she QAs all the guides.
tidal kiln
ok. kind of different form of QA. something you wouldn't really think of until it happens in the wild.
idle owl
Right, but she would be the one who could cause clearer wording to begin disseminating through the guide world. Not really reasonable to tell everyone individually but if she knows, and agrees, she can catch it on review and let folks know then. Then we get the word out.
tidal kiln
gotcha. for new guides. yah. good idea.
idle owl
Yep.
idle owl
@tidal kiln Do you have a moment to approve a bundle PR?
tidal kiln
maybe. send link. i'll take a look at least.
tidal kiln
@idle owl done. forgot, those are basically just text additions. not like code. easy mcpeasey.
idle owl
Thanks so much! Yep, nothing to it.
tidal kiln
@idle owl kept it simple, just added a blue info box:
https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-libraries#copying-libraries-to-your-board-2978253-18
idle owl
Good idea. Looks good. Maybe change "subfolder" to "folder" though, because it's not really a subfolder when you're looking to copy it? @tidal kiln
tidal kiln
yah. that sounds better. changed.
idle owl
Great! Thank you for taking care of this! I talked to Anne, she'll screen for wording in future guides.
slender iron
anyone on to approve https://github.com/adafruit/circuitpython/pull/3609 ?
blissful pollen
@slender iron if the role you gave me lets me, do i just go to the review and approve in the review changes box?
slender iron
@blissful pollen I can give you review access to circuitpython. it isn't the same as the libraries
blissful pollen
If you want to, sure

@slender iron @ionic elk In case you missed, I marked the TouchIO PR ready for review.
ionic elk
@analog bridge great! will try
idle owl
@lone axle Have you submitted a library to the bundle before?
lone axle
@idle owl I haven't
idle owl
Second question - have you linked to the MONSTER M4SK lib very many places yet? Because the actual product is in all caps. We should rename the repo if it's still ok to do so.
lone axle
I haven't really linked it anywhere except in the discord here once or twice. I think its probably fine to change it now.
idle owl
Or maybe not.. because camelcase makes it clear it's two words. What do you think? I'm not sure it matters.
I'll leave it up to you, should we leave it or match the product name?
lone axle
Lets go ahead and rename it. I definitely just autopiloted the name without considering the marketing used for the actual project.
idle owl
Right on, alright. Will do.
@lone axle Let me know if/when you have maybe 15 minutes today and I'll walk you through adding the lib to the bundle.
lone axle
okay will do. it'll be a couple of hours most likely on my end.
idle owl
No worries, that works for me as well.
blissful pollen
@tulip sleet @onyx hinge Thanks for the reviews, some were questions I for sure had, some were things I did not know. Don't think anything will be a tough fix. I did want to get I2CDevice out first before I started on SPI to learn for that
onyx hinge
Overall it looks good, happy to see the progress
@tulip sleet I would have to refresh my memory further about RUN_BACKGROUND_TASKS vs mp_handle_pending(). There's at least one place we do both right next to each other but I wrote it so it could be my misunderstanding
ionic elk
@meager fog is there support for the ESP32-S2 with arduino yet?
analog bridge
@ionic elk Yes... https://github.com/espressif/arduino-esp32/tree/esp32s2
ionic elk
Hmm, can I check out core branches after installing with the board manager?
Is there a git repo sneakily cloned in the IDE files somewhere?
Or do I gotta clone, checkout and install myself?
slender iron
I think you need to install yourself
ionic elk
blegh
analog bridge
After installing using boards manager... you need to replace the files in packages/esp32 directory with the files in esp32s2 branch
tulip sleet
we might have a guide explaining this; i'm looking
I might be thinking of this guide, which may not be that helpful: https://learn.adafruit.com/using-board-package-tool-to-update-adafruit-arduino-packages
ionic elk
Also, it's getting increasingly off topic for this channel, but the arduino IDE seems... slower... than I remember. Do most of you use the CLI?
takes a good 8 seconds just to open the preferences
blissful palm
Is there a feather board/Peripheral matrix/compatibility somewhere on Adafruit?
ionic elk
blissful palm
I.e. showing which pins are used etc..
tulip sleet
in general, all the featherwings are compatible with all the feathers, by design
ionic elk
Though you can't always combine different featherwings together cleanly - that's actually a chart I'd like to see
what featherwings can and can't be used simultaneously
blissful palm
Yeah I'm thinking about pin usage really here
ionic elk
So, like, an ESP32 coprocessor along with a logger or sensor featherwing? something like that? I think you have to go case by case
blissful palm
I would just love a matrix of pins used by peripherals, that would be a great start
From that working out combinations is simple
tulip sleet
that is an interesting idea, sometimes they are changeable too
ionic elk
Not sure exactly what that means - different feathers will have different peripherals based on the core they use. They just get arranged to the same places on the Feather so they're all compatible in similar ways
tulip sleet
for specialized featherings that are not just I2C or SPI, you often wire up jumpers from function pads to the pins you want to use
they try not to grab specific pins arbitrarily
blissful palm
sure, that makes sense especially for CSx like fuunction
ionic elk
@tulip sleet I think both the screen featherwings and the ESP32 coprocessor both have specific non-Busio pins that they claim
I designed my motor featherwing to have a couple options to work around which one you use
tulip sleet
ionic elk
Right, it'd be nice to have a chart showing which other featherwings the Airlift can work with. I think it works with the screen one, though I don't totally remember. But there are others I know it conflicts with
tulip sleet
i think part of the issue here is just having enough room to be able to select pins. The simpler featherwings have more room to assign pads
ionic elk
like a big ✅ and ❌ grid
idle owl
@tulip sleet I swear you messaged me yesterday about a Fritzing diagram but I don't see it now.
tulip sleet
@idle owl i did but I solved my own problem. It was a lot easier than I thought, so I just deleted the message. I don't understand why the Feather M4 fritz doesn't start out aligned properly, though
ionic elk
Could always have a "remap" featherwing haha
idle owl
@tulip sleet Fritzing is dubious at best. There is no understanding to be had.
ionic elk
that has isolated pinouts on the top and bottom and a bunch of jumpers you can use to map any pin to any other pin
idle owl
Good you got it sorted though.
tulip sleet
i took the plunge, and I am saving constantly. you are using 0.9.3b right, not the for-pay 0.9.4?
idle owl
I dug through their GitHub and found a dmg for 0.9.5 and am using that.
tulip sleet
also when I took a screenshot in fritzing it added a logo, I can just edit that out, or take my own screenshot externally
idle owl
Was thinking I'd go look again today to see if there are any new ones.
We leave the logo in when it fits.
If it makes the image too big or doesn't crop with it in there, we remove it.
But no, I'm not paying for it.
idle owl
The less crossed wires the better, but sometimes it's unavoidable. Otherwise no, not missing anything. Be aware when you put that in a side2 in Learn, it won't be able to crop it and include the whole image - you need to make the canvas taller so the side2 image processor can fit it all in there.
tulip sleet
def, thanks. this is complicated enough that I'm not going to side2 it. I made the pin assignments match something else, but it's pretty hard to avoid crossing in this case, which is why I spilled into the whitespace
idle owl
Spilling off the board is fine. I do it all the time.
If you want, I can do a little tweaking to it if you send me the file.
tulip sleet
idle owl
Also this: https://github.com/fritzing/fritzing-app/releases It's available on their GitHub if you look for it. I'm not sure where I found 0.9.5 now though. I can't find the list I went through.
tulip sleet
but don't feel obligated. I'll see your adjustments and try to model them later. I tried to make the takeoffs from the feather be perpendicular. I should probably try the same on the breakout
idle owl
Tweaking it now 🙂
@tulip sleet
It's like playing a video game. The more you play it, the easier it gets to know where things are and what will happen, but on the first try you get clobbered by a barrel no matter what.
tulip sleet
thanks!! much more attractive and parallel wires, and no overlapping the breakout
idle owl
You're welcome!

re: Airlift featherwing compatibility... are there any wings that don't work with Airlift? All of the displays are either I2C or use pins 11 and below. Airlift uses SPI + 11,12,13., so the red LED is the only thing it conflicts with. Adalogger is fine with Airlift. Adalogger and TFTs conflict when stock, but can be re-jumpered.
ionic elk
@crimson ferry I might be thinking of a TFT and something else, it's been a while
hence, the usefulness of a chart
blissful palm
Also what pins you are left with for your application
How do I find out which pins the eInk uses https://www.adafruit.com/product/4777#technical-details?
Obviously the SPI pins but which others
stuck elbow
blissful palm
Which is pin 7?
tulip sleet
@blissful palm guide is in process; here is the schematic
crimson ferry
conveniently, EPD featherwings use the same pins as the TFT featherwings
blissful palm
I am still a bit confused by which is pin 7 on feather
tulip sleet
there is no pin 7
blissful palm
I've only just noticed they jump from 6 to 9, never noticed that before!
@tulip sleet https://github.com/adafruit/Adafruit_EPD/blob/master/examples/EPDTest/EPDTest.ino#L13-L17
tulip sleet
that might be for a arduino-shaped shield, or is an arbitrary choice. change as necessary
On the featherwing, the BUSY pin from the display is unonnected. You can jumper it to some pin as you wish, or just leave it unconnected and the software wil use a fixed delay (as the library mentions)
blissful palm
@tulip sleet so those *CS pin jumpers are made when it ships, I would need to cut them to disconnect?
tulip sleet
yes, if you wanted to move them to other pins

re: Airlift featherwing compatibility... are there any wings that don't work with Airlift?
@crimson ferry The Enviro+ FeatherWing from Pimoroni is incompatible https://www.adafruit.com/product/4674 or at least you cannot use one of the sensor (maybe the PMS5003). Contrary to the Pi version, they use the analog sensor from the Feather for gas measuring, that consume a lot of pin. I believe every pin is in use. So to have Wifi and upload the measure, I have some hope for ESP32S2. Or BLE with a gateway to the internet.

I wrote a python script to download the latest library bundle, unzip it, and move the examples and lib folders out. If anyone is interested in automating your bundle downloads: https://gist.github.com/FoamyGuy/5918331c6cf005d6a1360cb7621988c8

@lone axle have you seen Circup? It also installs libraries to your board. Sort of like pip.

Has anyone seen anything similar to Arduino SimpleTimer: https://www.arduino.cc/reference/en/libraries/simpletimer/ but for CircuitPython?
lone axle
@idle wharf yep, am a big fan of circup as well 😄 Thank you for all the work you've done lately chasing down different issues related to Circup with python 3.9 btw. I will still probably use circup as well. I just wanted to create this script and then set it up to pull the latest bundle once a day. That way I always have a local copy of the most up to date libs.

can someone explain me (or hint where to find it) how the general process is of getting python libs as a mpy module to load in python? .. and whats the differences to compiled c modules?
I Want to do LED animations and am strugeling getting them Fast.
https://github.com/adafruit/Adafruit_CircuitPython_LED_Animation these here seem to be quite fast. .. about 100 times higher refresh rate than the one i wrote naivly. But i dont understand why. 😄

@lone axle - I was perusing the Good First Issues this morning and saw your PyPortal examples issue. What kind of examples? Aren't there a truckload of PyPortal projects? Or is this for something specific that has changed? It caught my eye, and I'm interested in helping, but I think I need some additional guidance.
tulip sleet
@untold wasp When you load a .py file, it's compiled by CircuitPython into "bytecodes", which are then interpreted. A .mpy file is just a saved version of this. It will not run any faster than a .py file after it's compiled. It's not compiled to native instructions.
Are you writing new animations based on the LED animation library? Are you saying the existing animations are running fine on the same board that is slow for your own animations? The existing animations are coded carefully to be fast and not to allocate lots of new storage on each animation cycle.
I will be afk for a while, sorry.
lone axle
@old smelt there are quite a few PyPortal projects in the learn guide system. Some of them might be perfect for what I'm thinking, but I haven't taking a look through all of them yet. Mainly I am interested in getting a few more small-ish simple-ish examples that can go inside of the examples folder of the repo.
Right now there is only a single one, and it really only shows off half of what the library does well. (In my mind this library is basically two halves, pulling data from the internet, and then formatting it and showing it on the screen.
untold wasp
@tulip sleet okay that clears up a lot for me already thy!
Does that mean i can just put animations in Modules in there non bytecode compiled form on the board with no performance penaltys?.
Ah No sory for beeing so unclear. My Slow try on a animation didnt used the animation libary but just the neopixel module... there was probably sth unrelated slow... didnt put mutch brain into that 😛 but now that i can build on the animation libary thats probably no problem anymore 🙂
lone axle
In my mind ideally we'd have enough examples to show at least one each of fetching plain Text, Image, and JSON data from the web and showing it on the screen with displayio.
old smelt
Ah... Ok. That helps. It's not clear in the issue that it's for a specific library. Or at least the internetty part of the library
lone axle
Ah, I could have probably chosen the wording it a bit more clearly in that issue. looking back on it now

@viral minnow Heya, catching up on old weekly meeting podcasts. LMK if you need assistance with porting TinyLoRa to the SX1262
old smelt
I really like the PyPortal as a human-machine interface.
But that's not really doing web fetching work
Though, it could
tulip sleet
@untold wasp Right, no penalty during the animation. The only time penalty is just at the beginning when the .py is compiled, but that's very short.
Yep, if you want to build on animations, take a look at what's in the library. Many of the animations are quite flexible, and may already be doing what you want. Or, just copy their style. Good luck!
blissful pollen
@untold wasp If you have questions I recently built two of my own custom animations using that library. (they're sitting in PRs so I think you can even view them there)
onyx hinge
Does anyone know if there's a Python tool for parsing the structure of mpy files?
tulip sleet
@onyx hinge circuitpython/tools/analyze_mpy.py
onyx hinge
aha I assumed it had to exist
tulip sleet
i remember seeing PR's or mentions it in the micropython repo. Maybe there is even more there, though the mpy format has changed
onyx hinge
yeah hmm it encounters an error with some of the mpy files I tried
I was hoping it would be trivial to examine mpy files to find out what they import, but it's not looking straightforward
tulip sleet
how about strings foo.mpy?
onyx hinge
that'll show a lot of strings 🙂 but not necessarily just imports
tulip sleet
sure, you'd have to cull it 🙂
if the analyze_mpy.py is buggy, you could try the version from upstream and see if it's better
opal crystal
Doesn’t mpy-cross have an option to output a disassembly of the bytecode?
onyx hinge
RuntimeError: missing code 0x8c at 7
``` seems like it simply doesn't know all bytecodesOh wait, you don’t have the source code. Then mpy-cross won’t help.
onyx hinge
current micropython has mpy-tool.py but it says my mpy file is an incompatible mpy version
(no big surprise there)
tulip sleet
we also have mpy-tool.py. Is that better than analyze_mpy.py?
onyx hinge
it does succeed in dumping a whole mpy file but it's in the format used for freezing in
weirdly the imports don't seem to be represented in it though
analyze_mpy can see MP_BC_IMPORT_NAME struct MP_BC_STORE_NAME struct which is import struct. but I can't find any BC_IMPORT_NAME in the mpy-tool rendition
oh well I should set this aside and work on what I'm supposed to be doing 🙂
ruby lake
Just got this matrix portal board as part of adabox 16, is it supposed to have a circuitpy: come up when I connect it to the computer
blissful pollen
@ruby lake I believe it is an ardunio sketch on it, double press the reset and you can install CP through the bootloader (at least thats what I did)
ruby lake
oh, its not running circuitpython out of the box, ok. Guess I got too used to that 😉
tidal kiln
@ruby lake yep, in this case it's preloaded with an arduino example. the non-adabox ones also ship with an arduino example. so will need to install CP.

@analog bridge how long do you think we can get power consumption during deep sleep on the esp32s2?
analog bridge
@analog bridge how long do you think we can get power consumption during deep sleep on the esp32s2?
@slender iron I am unable understand you question.... power consumption ? 🤔
slender iron
I should have said how low
how many microamps
ladyada was playing around in arduino and got ~250 uA
slender iron
so 20 uA hopefully without the ULP
analog bridge
yup....
slender iron
I worked a bit more on sleepio yesterday
added workflow_active for detecting when usb is enumerated or ble connected
analog bridge
I was just checking your branch for the usb check implementation...
slender iron
🙂
analog bridge
I'm almost done with rotaryio and countio for the s2... #3513 is next
slender iron
nice! Thank you!
analog bridge
@slender iron Can you do a early review on them, I only need to figure out the deinit function and multiple encoder support.
I am using the builtin pulse counter module instead of creating my own interrupt handler
slender iron
whenever you want me to look please mention me in a comment on a PR. that way I'll get an email
the pcnt peripheral should be good
analog bridge
ok... will ping you tomorrow
slender iron
I'll try and look today. doing NTP now so I can set up my alarm clock. 🙂
onyx hinge
@slender iron do I need to allocate DMA memory specially in esp32s2?
er I guess the API is allocating the DMA memory for me, maybe it's fine
I just specify buffer sizes
onyx hinge
slender iron
if you let the idf allocate memory then it should be dma-able
the idf doesn't use psram as it's configured
only the cp heap is in psram
onyx hinge
literal:
structure = ((struct foo) {x + y, 'a', 0});
``` Is using this C extension (supported by gcc and clang) preferable to introducing the temporary variable for these {}-initializers that esp-idf likes?i thought we liked the dot notation initalizers, e.g.
uint32_t zero_32 = 0;
mp_buffer_info_t zero_32_value = {
.buf = &zero_32,
.len = sizeof(zero_32),
};
(that's a typedef'd struct, but it could be regular struct)
onyx hinge
yeah but suppose instead of a local, I want to initialize self->i2s_pin_config .. ``` self->i2s_pin_config = ((i2s_pin_config_t) {
.bck_io_num = bit_clock->number,
.ws_io_num = word_select->number,
.data_out_num = data->number,
.data_in_num = I2S_PIN_NO_CHANGE,
});
vs ``` {
i2s_config_t i2s_config = {
.mode = I2S_MODE_MASTER | I2S_MODE_TX,
... .use_apll = false,
};
self->i2s_config = i2s_config;
}
but yes in each case using the C "designated initializer" .field = value syntax
I tend to think -- the "standard" syntax is a bit more verbose, but it's compatible. except, we know we'll never use anything except gcc (and maybe clang)
tulip sleet
that looks like a C++ assignment. if i2s_config_t is not a pointer, then it's a multiword copy, right, and I thought only C++ did that?? (This is the kind of thing I have to keep looking up.)
does esp-idf support Keil or IAR or other non-standard compilers?
onyx hinge
surely not
tulip sleet
i can find no uses like self->i2s_pin_config = ((i2s_pin_config_t) { in CircuitPython. I looked using a regexp.

@lone axle Did you run into any issues? I didn't see a PR to the bundle go by for adding MONSTERM4SK.
lone axle
@idle owl nope no issues sorry, I should have mentioned when I got it done. Limor merged it pretty quickly, it only existed for a short while as a PR.
idle owl
Oh good, ok. It's still on the list of missing from the bundle, so I need to look into why the check is still being triggered. Thanks!
lone axle
I just double checked in the latest bundle download and I do see it in there.
idle owl
@lone axle Thanks for checking!

I have Clue I2C question for external sensor connected with Stemma. I want to use the bus and the Clue library. Is there something more "clean" than this working code:
i2c_bus = clue._i2c
trellis = NeoTrellis(i2c_bus)
Can I avoid clue._i2c ?
Of course this import is above:
from adafruit_clue import clue
thorny jay
Perfect, works and that will be the same code with or without Clue library. Thanks
