just type file something.wav, and it should tell you the sample rate

low_fade.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 22050 Hz
Works on CPX and so on though. Or worked anyway.
idle owl
I don't know how to change that. I've never made my own wav files, always get them from JP
Do you have some?

that I haven't debugged in detail yet; I was trying to prevent crashes and not playing at all and getting stuck
do you have the sox program?
tulip sleet

idle owl
Ok
manic glacierBOT

@tulip sleet Then what do I do with it? Docs are... lacking.
tulip sleet
sox something.wav -r 16000 something-at-16k.wav converts something.wav to 16kHz sampling
idle owl
Ok thanks
tulip sleet
it is a messy CLI program

Brew is doing brew things. So it's taking forever.

This is why you never ever ever brew install python.

We'll need to document this limitation on samplerate somewhere or somehow.
Because it means a bunch of files we've used previously won't work.
tulip sleet
oh yeah, yeah, we still need to experiment, and it still might be terrible
I've only fixed some things so far
idle owl
16k is still a bit crunchy. Hmm.
Seems so anyway.
Making 8s.
@tulip sleet So, it seems better than it was? Also weird, they each play once but not again.... Like the whole program stops responding. Or one plays once and then everything stops responding. No LEDs, no HID....
tulip sleet
well, I was hoping to fix that π¦
tulip sleet
that's one of a number of bugs

tulip sleet
Did I forget to include it?
oh, ok! I was just going by the name
@slender iron When we switched back to the raspberrypi/pico-sdk, I lost the XOSC oscillator fix by accident, so it's not in alpha.5. It's in there forpico-sdk builds, but we don't use the pico-sdk board files. Where do you think we might put pico-sdk-specific settings for boards? Putting them in sdk_config/pico/config_autogen.h doesn't seem right, but perhaps that could #include some kind of RP-specific config.h for an RP2040 build for us?? I don't know whether you've thought about this.
I can't remember if you have specific board settings for anything right now
that is pico-sdk-specific. I don't really want to #include "mpconfigboard.h" or something into the pico-sdk sources
EDIT: I have an idea about adding a pico.h to our board directories, which will be included by config_autogen.h. I think that's the simplest for now. No comment needed for now. Next step is a PR.

@slender iron @onyx hinge I started to create a team of "CircuitPython core reviewers", so you could request a review from anyone on the core team. I was going to include @analog bridge and @ionic elk . But it turns out you can't add "outside collaborators" to teams, only team members, and you have to buy a seat for a member. So I gave up on this. You can ignore the invitation to join the (now deleted) team. Nevertheless, perhaps we can add more people as reviewers whenever we do a PR if any of those people could give a review. It's hard to indicate AND vs OR in terms of reviews. We can assume OR unless otherwise specified.

@onyx hinge The barometric pressure example on this page: https://learn.adafruit.com/ulab-crunch-numbers-fast-with-circuitpython/filter-example-measuring-barometric-pressure#low-pass-filtering-measuring-barometric-pressure-with-a-bmp280-3057472-1 doesn't seem to run on the CLUE any more, I'm getting pystack exhausted consistently when I try to run it. Truthfully I quite understand all of the math that is occurring, but I noticed if I remove some of the values from the taps array that is able to run successfully again. Do you know if it would be worth making that change in order to get it back to running or does that mess up what it's trying to illustrate?

@proper zodiac I think I may have generated them with scipy on a host computer: https://docs.scipy.org/doc/scipy-0.19.1/reference/generated/scipy.signal.hamming.html
lone axle
@onyx hinge on more question related to that example. I noticed that my filtered line seems to be pretty much straight horizontal, it doesn't appear to be "following" the jagged line from what I can tell. I also found in the code this import ulab.filter https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/d83d646233c791fcab25f8888dda4128d819d6fd/ulab_Crunch_Numbers_Fast/cluebarometer.py#L7 that doesn't seem to get used for anything after importing. I didn't see anything analogous to that in the newest version of ulab so I've removed it. But now I'm questioning whether it was actually somehow responsible for making that filtered line get drawn correctly somehow even though it didn't seem to be used (to my untrained eye)
onyx hinge
no, I think it was just unused
if you raise or lower the sensor by 3 feet / 1 meter does the line move about 10 seconds later? Based on what I'm remembering/reading that's what you'd want to see.
the reading should be constant if the sensor is stationary and nothing interesting is happening in the weather
lone axle
I did experiment with raising it up and down a bit and the jagged line does seem to respond to that but the smooth line still stays exactly horizontal to my eye.
onyx hinge
that doesn't seem right, if you change it so the average of the jagged line is +.2 from what it was before then the smoothed line should also move up by +.2
it's a very complicated way to compute an average
exactly horizontal seems wrong
lone axle
during the boxed section I raised it up at arms height for about 10 seconds, and the section after is back on my desk.
onyx hinge
yeah it's not working
mind sending me the code as you have it right now? I'll see if I can't fix it.
or figure out more about what's going on
lone axle
okay, I'll keep going with the ulab rename changes. I did notice the behavior seems the same using the current code on 6.3.0 as it does with my updated / renames and 7.0.0 alpha 5
thorny jay
Maybe just a moving average of the last 10 values will be more "simple" than this big table and using ulab? π
lone axle
yep, I can do that.
onyx hinge
@thorny jay the purpose of the guide is to illustrate ulab, so no π
@lone axle you never know, maybe what was committed never worked
thorny jay
<@!681528999520108564> the purpose of the guide is to illustrate ulab, so no π
It is a convoluted way to introduce to ulab...
onyx hinge
I'm going to accept that as a pun and move on
thorny jay

onyx hinge
data = np.roll(data, 1)
looks like you have to assign the result of calling roll, it's the same in numpy

onyx hinge
@lone axle ^ maybe this is the answer
lone axle
<@!382939733107408897> ^ maybe this is the answer
yep that seems to be it. The smoothed line does follow the jagged line with about 10 sec delay now. Thank you π. I'll include that fix in my PR.
lone axle
I think it's likely that it worked at some point because there is an image in the guide that depicts it with the graph following. But maybe it could have come from code that was modified after commit
thorny jay
Do you know if the intended use of the new ulab is not to do import ulab.numpy as numpy and then write the code using numpy.x?
onyx hinge
A lot of internet code writes import numpy as np. It is hoped that you can write code for a compatible subset of numpy and ulab by using import ulab.numpy as np. with a try/except clause, the theory is that it'll work on CP, MP, and py3
or maybe it's from ulab import numpy as np due to a MP limitation, I forget
lone axle
looks like both work.
onyx hinge
micropython (I have v1.15 handy) rejects import ulab.numpy as np but accepts from ulab import numpy as np
thorny jay
So that last form is the best I guess.
onyx hinge
It is not a goal of a CP guide on learn to be compatible with numpy or micropython, except that I think that guide has a section on numpy/ulab compatibility that needs to be updated

onyx hinge
any tidbits you can share?
ember iris
Argh if only I could remember his name, but he talked about how much they pulled from circuit python and had to massage into the calculator
Biggest notes were they had to use a subset because all of the I/O pin related features weren't needed, which caused them a ton of headaches in the build because of library issues, but that it worked well once the massaging was done
The guy was a 'I've been using assembly guy' and he worked on the tests there, and wasn't overly fond of the experience, but was darn proud of the team to get it working, and really happy circuit python had put so much into making the code work

ember iris
it looks strongly like the firmware update for the main calculator (Python.8ek) ...
I'm still working to wrap my head around the lower level of how the circuit python core functions. What would it embedding the bitstream do past keeping it compressed?
onyx hinge
I'm guessing that the main calculator CPU can feed the UF2 to the samd21 coprocessor where circuitpython actually runs, but that's not based on actually disassembling anything
that's just how they can update the embedded circuitpython version
ember iris
That structure does sound like a 'lowest energy' solution to slapping circuit python into an already existing embedded program. That way their years of code and tests are still present and they don't need to build those back up from the ground up

I'd like to make a breaking change to vectorio palette semantics.
Currently:
To color vectorio shapes correctly you have to pass in a palette with length 2. Palette[0] must be set transparent and palette[1] must be the color you want.
Proposed:
To color vectorio shapes correctly you pass in a palette with length >= 1. Palette[0] will be the color of the shape.

I don't think that the mp3 decoder will accept anything that isn't a file on flash or sd π
onyx hinge
it would be nice if mp3s in particular took any object with a readinto/recvinto method but that has not been implemented yet.
right now I think what you'd have to do is freeze in a block of memory that is a FAT filesystem image, then you can mount that with the storage module..
(if you went "ugh" just now, I agree)
cunning galleon
Ugh, but if it works for now!
onyx hinge
I wrote this once for image creation but it ended up not being useful to anybody. https://github.com/jepler/mkfatimg
then I think you need to wrap it with an object that implements at least count and readblocks methods; not sure if the other two are needed. The implementation can be in C or in Python. https://github.com/adafruit/circuitpython/blob/98cd989c16ab82bff10002359b09d4027a198a97/shared-bindings/sdcardio/SDCard.c#L176
to have it happen at boot time everytime you could poke it into the supervisor, see filesystem_init -- but I'm not sure what the secondary effects are of wanting a second filesystem
of course you could just make this part of the initial CIRCUITPY filesystem when you program your device, too, and if a user breaks it they break it. This can go in the same uf2 file if you have a unified flash for program & CIRCUITPY (like non-express boards, esp32 boards, and pico boards) or you would need a second step at manufacture to load it...

The current version of "adafruit_display_text" has a simple "display_text_simpletest" module. The code raises an exception from Label.py -- "Group full".
tulip sleet
which version of CircuitPython are you using?
cunning galleon
6
tulip sleet
The limitation on group size was removed in 7; the example should not fail, but try 7
cunning galleon
I modified the "BaseLabel" in the adafruit_display_text "init.py" to give a large "max_size" to groups. That seems to work.
cunning galleon
I'm not sure we can upgrade to 7 yet. But I'll check.
cunning galleon
The FREEZE process doesn't seem to pick up .mpy files in the target directory. I only have the version 6 libraries as mpy files (from the bundle).
Is there a link to the source for the version 6 libs?
tulip sleet
you can download a source bundle. You can also add the library you want as a git submodule. That is the way the current code is included, and is recommended so you can fix it to a specific version and update it easily.
cunning galleon
that's what I was trying when I got the "group full" error
I figured the source was already changed for version 7
tulip sleet
the source bundle for 6 and 7 is the same. we don't yet have a mechanism for including different library releases in the 6 and 7 bundles. The only difference is that they are compiled with different mpy-cross versions.
cunning galleon
OK. I dragged the "adafruit_display_text" source library from that folder to my board running version 6 circuitpython. I get the "group full" error.
I will modify my copy of that source to add "max_sizes" so we can get going.
The version 6 mpy files of that library work fine. But I can't freeze in mpy files.
tulip sleet
are you using the latest versions of the 6 .mpy files? There is no difference between the 6 .mpy and .py files except that they may have been updated recently
do not use the .mpy files just because they work
cunning galleon
understood. I don't know how to get the 6 .py files.
tulip sleet
they are in the bundle I circled in the image above. But if you have older versions, then that bundle is too new. So you can use an older bundle. Do you have the zip file for the bundle you are using? You can look at its timestamp in the bundle name
or just roll that particular library back
cunning galleon
how do i get an older bundle?
tulip sleet
for any paritcular library, go to its github release page and find the release you want
cunning galleon
so all i can get for version 6 is mpy files
tulip sleet
you can look at the PR's for a particular library to find when the group_size stuff was removed
the "py" bundle is the same for 6 and 7
the 6 and 7 .mpy bundles are both generated from the same py sources

tulip sleet
I looked for what DEBUG was doing
I think an issue would be good if we don't already have one
analog bridge
from esp32 forum
Because of some fixed RAM addresses used by the ESP32 ROM, there is a limit on the amount which can be statically allocated at compile time. Much more RAM is available at runtime via the heap (it is, as WiFive says, non-contiguous.)
There are some plans to work around this and allow more static allocation, but no ETA yet.
The best fix for the issue is to find a large statically allocated buffer in your program and change it to allocate dynamically (ie via malloc()).
i just wonder what DEBUG is causing to be allocated statically.
since we don't have the problem on regular builds
analog bridge
I think an issue would be good if we don't already have one

Not everyone knows to make a release or how to make a release. Dylan does weekly releases usually, but she's out of town at the moment and is working sporadically so I think it's not happening as consistently. circuitpython.org/contributing/library-infrastructure-issues says the following libraries have commits since last release: ``` Library has new commits since last release over a month ago
https://github.com/adafruit/Adafruit_CircuitPython_MCP230xx (99 days)
Library has new commits since last release within the last month
https://github.com/adafruit/Adafruit_CircuitPython_Simple_Text_Display (11 days)

tulip sleet
no, a bug in the audio code was overwriting the list of keypad scanners, causing scanning to stop. The keypad list happened to be just after an array used by audio to record info about a play in progress, and something wrote past the end of that array, and smashed the keypad scanners list

what are you looking for exactly ? keyboard layouts for adafruit_hid ?
might I interest you in this ?
https://github.com/Neradoc/Circuitpython_Keyboard_Layouts
I'm trying to get it started, though I want to integrate ways to layout.write "éà ç" etc. maybe the way it's done here: https://github.com/AngainorDev/Adafruit_CircuitPython_HID/blob/layouts/adafruit_hid/keyboard_layout_fr.py
and there's a dvorak layout that was proposed too
tulip sleet
I think just defining some classes that are collections of constants, like KeycodeFR, KeycodeDvorak, would be a good start.
jaunty juniper
the rework proposed in that PR would help I think ? https://github.com/adafruit/Adafruit_CircuitPython_HID/pull/61
thorny jay
My idea was that Adafruit should show the way a localisation should be done, with one example. And then people will be able to follow that and adapt for their own language. There was one PR for French keyboard and one PR for German keyboard. French was just a replacement library (if I remember well) that you use in place of adafruit_hid. German, I don't remember how it was done. But if there is one way, that would be the recommended way to do it, that is not inflating the size of the library (because that was an issue), and other people can provide their propose for their keyboard... then you have valuable input that will not be rejected. I started working on Belgian keyboard 12 or 18 month ago, but I would not invest time in a PR that will be rejected because it is not done in a way that make sense.
The same way other PR have been rejected later.
There was a similar issue with Joycon support.
There was a request from the community to support other Wii device, such as joystic, guitare, name it.
We had to do the PR 3 or 4 time before it got accepted and it was decided on the proper way to extend the libary that was Joycon only.
jaunty juniper
that's why I made the Circuitpython_Keyboard_Layouts repository, to get all the keyboard layouts in one place, also showing a way to make one, they can be downloaded from the Circuitpython_Keyboard_Layouts bundle, and soon installed individually with circup

Ok, if that is the official way, and is recommended/approuved... then that is fine.
jaunty juniper
well it's not official by any means
the idea is to add third party bundle support to circup, and maintain the library
maybe once it's solid, move it to the circuitpython org if it can be agreed upon
thorny jay
I love it, the PR has a lot of French discussion. π
Let me dive in before having an opinion. π
jaunty juniper
the point is to make a repo that people can contribute layouts to, and as a bonus make it easy to install only one at a time
thorny jay
And this can go "in the weed" topic (it was already more than a year ago).
My message to Adafruit CP community was: "Ok, you made the translation a key differentiator of CircuitPython. Once weblate was in place the community was able to contribute, new language came, they get updated. So if you are serious about the language issue, you should also worry about keyboard".
Now my message to Adafruit could be: "Ok, so you made Keyboard thing a big part of your new development and product. That MacroPad in the Adabox is the peak of that evolution (even if Adabox is not shipped to Europe anymore), but if you only have EN-US keyboard support, you are excluding a lot of people (hint: customer). The same way you try to be an inclusive company (race/gender), you cannot be or stay US centric on your keyboard side. (I did fight some US centric learn guide that did temperature in FΒ° too)."
I wonder if I am good at lobbying companies. π

I could be wrong, but I thought the plan was to create separate libraries for each keyboard layout. The issue is that we can't add more to the HID library at this point in time - it is frozen into certain builds, and there is not enough room. So, creating a separate module for each new layout means that folks who want to use them can, but they are not making it impossible for us to continue with some current situations. We can certainly discuss this in the weeds again. If this is the case, then I am happy to create repositories to get things started. MacroPad, for example, has plenty of space to handle many different layouts, so there's no concern there.
idle owl

@slender iron FYI, I instrumented the buffer filling by toggling pins, and it's yielding useful info

first buffer is loaded in the top spikes; second in the lower spikes. This is time spent in the "next block" routine
slender iron
that gap is concerning
tulip sleet
possibly, it's actually quite regular. I could easily turn off GC in that time
to check

disabling GC before the play does not change the glitch

Yes, that was the idea and reason for that solution. But devil is in the details and practical implementation help test the idea and detect flaw or problems.
I think someone need to bootstrap the work and show the first vetted alternate keyboard. Because writing the Nth rejected proposal is not fun. The other will follow. Maybe some keyboard/languages will have challenge, like dead key or diacritics (?).
jaunty juniper
they are rejected because they are made to the adafruit_hid repository, when the idea was that it should be a repository on its own, there's a guide for that, use cookiecutter, publish your library, do a PR to the community bundle
https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library
idle owl
Exactly what Neradoc said. We need them submitted as separate libraries. What I'm saying is that I believe Adafruit is willing to host them, so they're "official" libraries, and do not need to be hosted by the author. But again, I would want to verify that.

Sry phone that should say /usr/bin
tulip sleet
basically never use sudo pip to install something, because it can mess up the system-installed commands that the system needs for its own purposes.
low sentinel
Yep
tulip sleet
there is an automatic way that ~/.local/bin gets added to your path. Let me find it.
this is in your .profile, which is only executed by a login shell:
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
PATH="$HOME/.local/bin:$PATH"
fi
Oh? I didnβt see that but if thatβs what is supposed to be on path I can easily put that in zshrc
Mm yes
low sentinel
Thanks for your help. I agree thisβll be it
tulip sleet
the gotcha is that if you install something with pip for the very first time, it creates ~/.local/bin, but it doesn't get added to your PATH, because that stuff above didn't see ~/.loca/bin when it was run at the beginning. So you have to log out and log back in, and then it's on your path. So it might be that if you exit the WSL2 shell and then go back in, it will just work.
this is very confusing, and has happened to me on fresh installs
low sentinel
Nah this actually persisted across a shut down and a startup.
This is very good to know. I basically never use pip installed tools by name like this
Unfamiliar with pip distribution of executables
tulip sleet
it could be that zsh doesn't run .profile?? or maybe you edited .profile. The distinction between login shells and regular shells is not obvious, and i don't know what happens when you create a WSL2 session
i find this all kind of a mess
low sentinel
I didnβt edit profile

I'm thinking flash LEDs, moving things, that kind of stuff. The stuff that draws...
OK I will think on it for a bit and come up with a shortlist.
@onyx hinge I need your brain for a moment. I have to rename a bunch of files that show up in a find search, and I bet you know how to do that not-manually.
onyx hinge
okay
you will want to tell git that you are renaming the files, which is the git mv command. You need to run it once for each thing that you find. Do you know, are there spaces in some of the filenames?
or other characters that give shells the willies
idle owl
All of the file names are main.py. The directories all appear to be letters with _
onyx hinge
it looks like in the learn system the filenames are all file for the simple technique, yay
idle owl
you will want to tell git that you are renaming the files, which is the `git mv`...
Run it once for each thing? So it's still kinda manual?
onyx hinge
There are lots of ways to to this, but here's one way I would do it
git ls-files "**/main.py" | while read fn ; do echo mv $fn ${fn%main.py}.code.py; done (or use your find instead of git ls-files, it's about the same)
this will print a sequence of 'mv' commands. you can either execute them by using copy & paste, or by modifying the line and removing "echo"
I can explain any of it you like, but it may not be worth the trouble; your goal is probably not to become an expert in bash shell
idle owl
I think I understand what it's doing?
onyx hinge
Probably? It's just stuff like, nobody knows until they learn it that "%" is removing a matching suffix from a variable, for instance...
oh except it's wrong
idle owl
Oops.
So need to run it again against .code.py ?
wait
I can stash and drop
and then rerun it.
onyx hinge
sure, that's a great alternative
do you see which "." to remove?
git ls-files "**/main.py" | while read fn ; do echo mv $fn ${fn%main.py}code.py; done
onyx hinge
after stash+drop?
onyx hinge
oh oops, two mistakes
idle owl
stash didn't make them untracked.
onyx hinge
git ls-files "**/main.py" | while read fn ; do echo git mv $fn ${fn%main.py}code.py; done
remember I said we needed to tell git that we were renaming? I left the git off of git mv
idle owl
Would this work? git ls-files "**/.code.py" | while read fn ; do echo git mv $fn ${fn%.code.py}code.py; done
onyx hinge
no, for a number of reasons
idle owl
ok
onyx hinge
git ls-files doesn't list untracked files
git ls-files -o might
but git mv won't want to move them, because they are untracked
onyx hinge
the original main.py files are what stash and drop put back, the untracked .code.py files we just want to delete, which git clean can help with
idle owl
ah they are back indeed.
OK it's not as bad as I thought then.
How can I use git clean then?
onyx hinge
try git clean -n "**/.code.py"
it should say it would remove all those files, change the -n to -f to do it
aren't you glad we automated this and saved time?
idle owl
ok branch is back to normal.
idle owl
aren't you glad we automated this and saved time?
llol
So back to this? git ls-files "**/main.py" | while read fn ; do echo git mv $fn ${fn%main.py}code.py; done
minus the echo to do it.
The commands look correct at least.

@tulip sleet How would I go about making wav playback in the MacroPad library be non-blocking? I thought it was blocking by nature, but PhilB indicated it is not, in fact.
tulip sleet
<@!329766224093249548> How would I go about making wav playback in the MacroPad ...
don't do "while playing"; that's what's causing it to be blocking. But right now it gets messed up if you try to play something when something else is already playing
idle owl
don't do "while playing"; that's what's causing it to be blocking. But right now...
Ok, so for now it should stay as is?
tulip sleet
for now, yeah, it will just raise more issues until it's fixed

@slender iron btw I do not see the huge memory consumption when debugging LTO on say, SAMD51. I am using the gdb from the arm download
slender iron
what versions of gcc and gdb are you using?
tulip sleet
$ arm-none-eabi-gdb-py --version
GNU gdb (GNU Arm Embedded Toolchain 10-2020-q4-major) 10.1.90.20201028-git
$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Arm Embedded Toolchain 10-2020-q4-major) 10.2.1 20201103 (release)
I have gdb 10.2 and gcc 10.3
tulip sleet
yeah, you are using the arch ones, I guess, you might try the ARM download
tulip sleet
i have seen gdb regress and then get fixed several times (e.g. tab completion has been horribly slow and then got fixed)
tulip sleet
the thing about the ARM release is that we know it's vetted
slender iron
tulip sleet
https://sourceware.org/bugzilla/show_bug.cgi?id=27754#c15 So, IIUC, this is a GNU ld bug, fixed in git.
tulip sleet
ah, they just updated the ARM download, as of July 29:https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads

does it have to do with the bootloader problem?

it defaults higher and as a result pyocd was clearing more flash than it should have
onyx hinge
and the tilegrid stuff?

Usually AMAs are done by setting them up ahead of time, and by the time you stop by there are questions ready, it's not a feed like structure like discord

i just checked it, was all, and it was a good q. I will drop in the same manner I would in discord. And I might point people to discord or the forums if they need extensive followup
ember iris
That sounds good to me
Let me double check with Joe before you link to the discord, I want to check on something
tulip sleet
yes, I hesitated on that, since there's a subreddit
ember iris
You're welcome to direct them here, I just don't know if posting a link on reddit, which can easily be scraped, would invite raid spam. I don't want to say go for it and then leave you to deal with spam that I could have prevented
tulip sleet
then I would just point to something that points to discord; i understand
ember iris
So I'm checking with Joe to see if the python discord gets raid spam
ember iris
then I would just point to something that points to discord; i understand
That was exactly my thought, "you can find a link to the discord on the circuit python main page"--something like this. Less likely to bring you unwanted spam that way
ember iris
Joe hasn't seen much of an issue for raids coming from the subreddit. But I'd imagine pointing to something that points to the discord might still be a better idea. I just wouldn't worry too much if you do directly link here

@stiff pelican Did you notice Scott's comment about using board.ID to store our usable name to link to the download page? I was curious if you understood his comment about the potential conflict with an "ID" pin. that didn't make sense to me.
https://github.com/adafruit/circup/issues/113#issuecomment-892838973
Oh.. if a board has a pin mapped to "ID" ...
We can look for that I bet
jaunty juniper
I don't understand what you want to do with the board module anyway
idle wharf
I'd like there to be someway for circup to direct a user to the board specific download page when there is a new version of CP available.
jaunty juniper
yeah, but that has nothing to do with board modules or os.uname
stiff pelican
<@!690965887167103008> Did you notice Scott's comment about using board.ID to s...
I assume he is allowing for the possibility of board having an ID pin or object but I don't know of one offhand.
jaunty juniper
we can't make circup connect to the board's serial REPL, interrupt the code, run print(board.ID) or anything
idle wharf
We're trying to find a place to that value... board.ID was suggested... as was os.uname() as was boot_out.txt
jaunty juniper
that's way too complicated (just finding the right serial port, if it even exists) and intrusive
idle wharf
If its defined in board.ID can the boot_out.txt generator (?) read it and write it ...
So its available both ways ?
jaunty juniper
it can in any case, it's a matter of having a define
stiff pelican
There was also a comment from Scott
I like the idea of making the board id available from CircuitPython. I did that somewhere once.... I'd like to see it available to Python code as well, not just boot_out.txt.
jaunty juniper
yeah sorry, I guess I just found it weird to have that conversation about board in a circup issue
idle wharf
I was assuming it would get added to board and then to boot_out.txt ...
Does that sound like a workable solution ?
jaunty juniper
for me the process would be to add the board ID somewhere as a define in the core, whether automatically generated or manually, then add it to the boot_out.txt which is as simple as adding the define name to this line: https://github.com/adafruit/circuitpython/blob/be2342f32f80a0a2ba6839333847b1fdb495b439/py/makeversionhdr.py#L110
adding it to board or uname is a completely independent process in my eye
idle wharf
That makes sense ..
I was just going looking for that boot_out stuff, thanks!
Not being able to search on GH is a pain .
jaunty juniper
ah the file says "This file was generated by py/makeversionhdr.py" I should have a look at that, it must be filling in the %s for the target before building
yeah I use silversearcher locally
what am I saying, I AM looking at makeversionhdr.py, I meant I should look how to add the board id to it π
idle wharf
Another angle is to enforce that MICROPY_HW_BOARD_NAME is the download URL path ...
https://circuitpython.org/board/unexpectedmaker_feathers2_prerelease/
cat /Volumes/CIRCUITPY/boot_out.txt
Adafruit CircuitPython 7.0.0-alpha.3-433-g5a4a80336 on 2021-06-25; FeatherS2 PreRelease with ESP32S2
jaunty juniper
it's supposed to be human readable like #define MICROPY_HW_BOARD_NAME "Adafruit ItsyBitsy RP2040"'
idle wharf
It could human readable and the URL is just replace spaces with underscores
Need more GUIDs ..
jaunty juniper
how do you like my new boot_out.txt ?
Adafruit CircuitPython 7.0.0-alpha.5-117-gbe2342f32-dirty on 2021-08-07; Adafruit QT Py M0 Haxpress with samd21e18
BOARD ID: qtpy_m0_haxpress
boot.py output:
Oooooo so lovely !
So the URL path is the port path ..
circuitpython/ports/atmel-samd/boards/qtpy_m0_haxpress/
circuitpython/ports/esp32s2/boards/unexpectedmaker_feathers2_prerelease/
I didn't realize that ...
Test sample of 2 ... might not be true
That does not appear to be guaranteed ... unless board id in the directions equates to the folder name in the path ...
https://github.com/adafruit/circuitpython-org#readme
To add a new board to the site:
Duplicate template.md to _board/<board id>.md.
Edit _board/<board id>.md according to the template's instructions.
It must mean the folder name ... there is not other value in the files in
circuitpython/ports/esp32s2/boards/unexpectedmaker_feathers2_prerelease/
which has that value they're using in the url path
jaunty juniper
as far as I know the only exceptions are alias boards as I mentioned in the issue

I don't have experience with that device specifically so I can't be certian. But I don't believe there is a helper library written for that chip currently.

are there specific versions of the pip requirements from requirements-dev.txt to build the core? I'm noticing that today I'm getting this error when I try to build:
ModuleNotFoundError: No module named 'click._bashcomplete'
make: *** [../../supervisor/supervisor.mk:68: build-pyportal/genhdr/devices.h] Error 1
I just made a build a week or so ago and it went successful. I don't think I've changed anything in between but not 100%
jaunty juniper
yeah, it requires typer, which requires click 7.1.2, click 8 breaks compatibility with the completion, and circup switched to click 8
so if you updated circup to test the auto PR, and don't build Circuitpython in a virtual env, you need to do that and install click 7
lone axle
Ah, I see. Thank you
jaunty juniper
that's my guess
lone axle
I wonder if there are plans to change the core build to work with click 8 or if we should make that line click==7.1.2 int he requirements file
and yep, you are right. Downgraded to 7.1.2 and have successful build now.
jaunty juniper
yeah it's a long standing issue, typer does require click==7.1.2 but the requirement is not passed along when installing apparently, so some people get a lower version, so that was added to the build guide: pip3 install --upgrade click==7.1.2
on a side note, I would love a way to install a tool like circup in a virtual env, while still available from the path in any shell

does anyone know of a spot in the core, or any other example code that would show to create a list and append things to it? Specifically I'm looking to append another list that contains ints representing x,y pixel locations.
Fumbling through it a bit I found mp_obj_list_t and I think this might be what I need but I'm not sure how to properly append things to it, and then append it to another list.
low sentinel
Fumbling through it a bit I found `mp_obj_list_t` and I think this might be what...
You can mp_obj_t list = mp_obj_new_list(0, NULL); and add stuff to it. This method adds tuples from a backing array.
lone axle
Thank you!

np. Btw do consider just doing 0, NULL to start with. You'll segfault if you pass in the wrong length and then try to use it in python π¬
humble shadow
Hi, I've built circuit python for a custom board and have it working. I'm curious about Arduino though; are Arduino files created at the same time when you build CircuitPython? I think I remember reading somewhere that if you add a board to the CircuitPython repo, it'll have both CircuitPython and Arduino configs created for it.
lone axle
@crimson ferry do you happen to know if LED or L is preferred as a name for that pin? Or maybe both of them should be available?
crimson ferry
I think both... I believe we always want to match the silk for ease of use, and board.LED has recently become a standardized expectation iirc
crimson ferry
PyPortal is a good example, it had L originally, but LED was added more recently https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/pyportal/pins.c
so now there are three ways to address the LED
lone axle
Nice, I missed it on my first look, but Metro M0 and M4 do have LED already, I'll add one for L
atomic summit
Hi everyone... been absent for a while focusing on hardware production. So the neopixel library and it's use of the NEOPIXEL_POWER pin - and IO locking....
How is a user supposed to have control of the power of the neopixel, or if a user already has control of it, how is the lib supposed to work, when the IO is "in use" ?
All of my boards have the explicit ability for user control on the "thing" that enables or disables power for the RGB LED - but this IO locking thing prevents this from working, or if the IO is assigned by the user already, it prevents the lib from working.
I'm failing to understand how this is all supposed to work now that power control has been added to the neopixel library - I know it was done a little while ago, but it's causing code breaking changes for me π¦
is there a way to check if an IO is "in use" ? an attribute?
This is all with 7 alpha 5
Traceback (most recent call last):
File "code.py", line 8, in <module>
File "neopixel.py", line 123, in __init__
ValueError: NEOPIXEL_POWER in use```or is it reasonable to add a try/exception NEOPIXEL_POWER in use in the neopixel library to allow it to bypass the power pin control if the IO is already in use?
tulip sleet
@crimson ferry @lone axle As I mentioned, we don't really want to have both board.L and board.LED. board.LED is canonical. I won't remove the board.L's right now, but I don't want to add more either (despite the silk). (We don't have board.MO and board.MI either.)
crimson ferry
@lone axle sorry I steered you wrong, I thought the silk was a stronger signal
tulip sleet
np, this isn't really written down
lone axle
no worries here. I'm happy to get the practice modifying things and building the core.
low sentinel
yo @analog bridge thanks for the tip on uncrustify, that was the issue.
lone axle
I've worked out that I can get the length of a list in core code by having it set into a variable by mp_obj_list_get() is there a way to get the length without specifically getting an item out of the list? or is that the best way? Also is there any sort of resource to learn things like this about working in core code at this point or is looking around at existing core code the best thing to do to pick up things?
low sentinel
mp_obj_list_get doesn't get items out of the list. It just gives you a pointer to the raw vector of items and the length of that vector. That's the right way to get the length; it costs 1 extraneous pointer write though. You could add a function:
size_t mp_obj_list_get_length(mp_obj_t self_in) {
mp_obj_list_t *self = mp_obj_cast_to_native_base(self_in, &mp_type_list);
return self->len;
}
(untested)
lone axle
Ah, I need to probably read up some more on pointers honestly. I don't have any real prior experience with C or any other languages where they are not hidden to a larger degree. I used code like this to do what feels like getting an item out of the list (and the length):
mp_obj_t *current_point;
size_t list_length = 0;
mp_obj_list_get(fill_area, &list_length, ¤t_point);
mp_obj_print(current_point[0], PRINT_STR);
Thank you for pointing me toward Polygon inside of vectorio btw. I've only taken baby steps but even those I would not have been able to manage without that help.
manic glacierBOT
low sentinel
so you're printing fill_area[0] with that code. I think you should rename current_point to fill_area_content or something if fill_area_content[0] is actually the current_point but idk what this code actually is doing so maybe it makes sense :-p
Anyway good luck! Pointers are good.
lone axle
Thank you. I do think some renaming is in order. fill_area is a name left over from the python implementation that I am trying to move into the core. It's a "paint bucket" style fill into a bitmap.
