I wish the supervisor storage allocator had more mechanism to copy things in and out of the heap. I did this tricky thing for USB where I store some data temporarily on the stack in main.c to keep it between VM instanatiations. I didn't realize intially that the supervisor allocator didn't work when a VM was running.

[adafruit/circuitpython] Issue opened: #4791 NeoKey Trinkey crashes into hardfault handler with example that previously worked

The actual example is significantly longer, but I narrowed it down to the following 10 lines of code to reproduce it. Tested on two different NeoKey Trinkeys running the same firmware.

Limor reported that the original example worked fine a few weeks ago. (If I change the setup order, it works now.)

[adafruit/circuitpython] New comment on issue #4775: Check bounding rect calc for text updates

When I was working on ParallelBus for RP2040 I ran into a speed problem as well, and could not find any limitation in the product sheets for the displays so I'm not really sure. I found the same thing @kmatch98 has that the ESP32S2 supports SPI at 80Mhz. And I'm at a loss (or missed something) as to why the M4 Hallowing seems okay with 60Mhz.

I do know the official ESP32S2 Arduino library has SPI default to 1 Mhz and that is what the displays will start as.

[adafruit/circuitpython] New comment on issue #4775: Check bounding rect calc for text updates

This all may not be new info, but... my understanding is that setting and checking SPI frequency has no effect unless you do it within the context of the object. For example, you can check actual ESP32SPI speed with:

with esp._spi_device as espspi:
    print('{:,}'.format(espspi.frequency), "Hz")

But Fourwire has no such method that I know of. I get no immediate error setting it to 80MHz. Default looks to be 24MHz:

[adafruit/circuitpython] Pull request opened: #4793 reduce SPI display baudrate from 60 MHz to 5 MHz to eliminate display glitch

This is a workaround to eliminate the display glitch reported in: https://github.com/adafruit/circuitpython/issues/4775

This PR reduces the display SPI speed from 60 MHz to 5 MHz.

(Note: Not sure if this is a workaround or a fix, since it is currently unclear why the display glitches occur at higher SPI speeds. The same glitches occurred on ILI9341- and ST7789- driver displays. Perhaps this is an issue with the ESP32-S2 SPI timings at higher speeds.)

[adafruit/circuitpython] Issue opened: #4794 analogio: correct ADC scaling to 16\-bit range

Affects all versions of CircuitPython, all architectures.

The approach currently used for scaling ADC inputs to 16-bit range never actually reaches 65535. For example, the oft-seen Python snippet:
coefficient = adc.value / 65535
will never return 1.0 under any circumstance.

There are two ways this might be corrected: fix the conversion (which might break or alter existing code behavior), or provide a constant that can be used for division to correctly attain 0.0 to 1.0 range.

[adafruit/circuitpython] New comment on pull request #4793: reduce SPI display baudrate from 60 MHz to 5 MHz to eliminate display glitch

Here's a quick first look at what it might take to split out the sending of "setup" vs "bulk data" with different speeds.

Data is sent to the display using a structure displayio_display_core_t with a begin_transaction function. Currently, the same begin_transaction function is used for both "setup" and "bulk graphic data" ([for bulk graphic pixel data see Display.c _send_pixels](https://github.com/adafruit/circuitpython/blob/3bcbf2bdbbfee1a0835a2213740ca70959b3efcb/shared-module/d...

[adafruit/circuitpython] New comment on pull request #4793: reduce SPI display baudrate from 60 MHz to 5 MHz to eliminate display glitch

I think having two baudrates would be the best fix for this (and 7.x is a good time to do it!). data_baudrate and command_baudrate could provide two knobs and baudrate could set both and be deprecated in 7.x.

command vs data is given with display_byte_type_t to send. the configure line should be moved from begin_transaction to send so it can change the speeds for each.

Is there any good way to reduce the startup time of circuityython?

[adafruit/circuitpython] New comment on issue #4803: on the problem of esp32 startup and wake up too long

The current code does not enter true deep sleep if you are connected to a host computer. The idea is to allow you debug a deep-sleep program and not get stuck in an infinite deep sleep loop, where you cannot edit your code, since USB would be disabled during a deep sleep.

However, it can take several seconds for the USB negotiations to finish, so we wait up to 5 seconds to see if USB is really connected.

The issue of being locked out from code changes happened to me personally a number ...

[adafruit/circuitpython] New comment on issue #4803: on the problem of esp32 startup and wake up too long

If you are going to be in mass production, then it might make sense to make your own build of CircuitPython.

If you want to shorten the delay, you can change the value conditonally defined her by defining in it ports/esp32/boards/<yourboard>/mpconfigboard.h.

So, who do I talk to about some docs?
https://circuitpython.readthedocs.io/en/latest/shared-bindings/support_matrix.html
I've landed on this page a few times, trying to "pick" a board based on supported features. I feel it's more practical to check if circuitpython supports module A on board X, because even if the device has the hardware, if circuitpython doesn't support it... well it doesn't do me much good.

While totally functional, I wanted to see what I could do to make that page more awesomer. I don't want to promise anything, and I don't know the capabilities of Sphinx, so I figured I'd start by building the docs locally but I'm running into trouble fresh out the gate.

So far:

  • pulled master from adafruit/circuitpython
  • install dependencies like the docs say:
pip install sphinx
pip install recommonmark
pip install sphinx_rtd_theme
  • run make html
  • install dependencies the docs don't say, isort, black
  • run make install a third time, and get this:

circuitpython-stubs/_eve/__init__.pyi

requirements.txt is a python thing, and it is mentioned in the learn guide, but if you have enhancements for the documentation, please open a PR or an issue

silver blaze
#

So is that one of those habits? pull python repo, run pip -r requirements.txt go about your business?

#

while you're here, does the docs depend on anything built in the binaries? like do I need to build circuitpython to build the docs?

jaunty juniper
#

I don't think so

silver blaze
#

I guess having commands like this in the docs:

 pip install sphinx
 pip install recommonmark
 pip install sphinx_rtd_theme

gave me the false confidence that's all I needed, since it was so low level.

#

why is there an install command anyways when it's already in requirements.txt at a specific version?

jaunty juniper
#

๐Ÿคท

silver blaze
#

haha that's fair.

jaunty juniper
#

I've been contributing and building Circuitpython occasionally since like January, I'm fairly new

silver blaze
#

I've been a software engineer for the better part of 2 decades, in quite a few languages, and I've avoided python ... it feels like I'm a cowboy at a rodeo without my own lasso ... how am I supposed to get those cows?
Meh it's all 1111s and 000s ... I just need to learn the quirks of Python.

#

Installed requirements, and BAZINGA! ... same make html error.

#

installed both requirements-dev.txt from the root and requirements.txt from the docs ... hrrmmm

#

what is ulab?

#

FileNotFoundError: [Errno 2] No such file or directory: 'extmod/ulab/code'

#

interesting, the directory extmod/ulab is there but nothing in it.

jaunty juniper
#

ah

#

did you git submodule sync --quiet --recursive && git submodule update --init ?

silver blaze
#

.... I did not, and why the heck would I do that? that's nowhere in the docs

jaunty juniper
silver blaze
#

ha sorry .... like why isn't that in the repo?

#

also, that learn article, I can't find it referenced in the repo either

#

if your build article is detached from your code like that, you won't have historical references on how to build specific versions ... that's too bad.

jaunty juniper
#

yeah I guess it's not as maintained as the learn guides

silver blaze
#

uggh.... also, while it might look pretty, don't put the bling in command blocks

#

copying this code does me zero good

#

I don't need another step between me and toast

#

jaunty juniper
#

oh yeah "copy code" is a trap !

silver blaze
#

+1 for VSCode and multiline select.

#

does learn.adafruit.com have any sort of API?

#

woot! thanks @jaunty juniper got it building

#

now if I could only learn to not hate python...

jaunty juniper
#

learn is an internal tool to adafruit, it can pull from github though (most of the demo code in it is hosted in the learn repo)

#

(the demo code, not the code running the pages)

silver blaze
#

it would be nice if the docs could be versioned in github and pushed to learn.adafruit

#

jaunty juniper
silver blaze
#

Thanks for the legwork. This looks really "pythony" and possibly not something I'd want to work on. I'm currently working on Typescript for the dayjob, so I wanted to see if I could use some of that but clearly not.

jaunty juniper
#

yeah, for the filter I mostly added a bit of html and a css and js file, sphinx is using a pre-made template and I didn't want to tinker with that too much

@slender iron have two minutes?my two questions from friday ๐Ÿ™‚

slender iron
slender iron
still zephyr
#

So, first, I see that when importing a libraries it matters if you import the file inside or outside a directory, there is a reason why?

#

this is for memory allocation problems

slender iron
#

it changes the memory requirements?

still zephyr
#

no the same file

slender iron
#

can you give me an example?

still zephyr
#

yes

#

if I import the file like this import dps310

#

no memory allocation problem

#

now if the file is inside a directory named adafruit_dps310 and I do the import like this

#

import adafruit_dps310.dps310

#

the I have memory allocation problems

idle owl
slender iron
#

what is in the __init__.py? I think it is imported first

still zephyr
#

nothing in the init

slender iron
#

hrm, may be tight on memory

#

I think the only extra memory will be the package dictionary

still zephyr
#

ohh i see package dictionary gotcha thanks.. second question ...

#

why import order matters, for example...

# 
import adafruit_dps310
import time
import board
#

no memory allocation problems

#

but this

# 
import time
import board
import adafruit_dps310
#

memory allocation problem

#

because of the heap size?

slender iron
#

ya, you'll just get a couple more dictionary entries before the large import

#

how big is the allocation that fails?

still zephyr
#

mmm, did not write it down, but for sure I will have more examples this week when I work with the BME280

#

I will write those down

slender iron
#

if they are more than 100 bytes or so then there may be a way to split the memory up so it fits better

still zephyr
#

gotcha, thanks ๐Ÿ™‚

#

I will look into that and report back neokey

slender iron

thanks!

@tulip sleet I'm assuming you've already seen this but kmk would be a good starting point. afaik it uses circuitpython

tulip sleet
#

i did look at kmk, it does a simple scan with no FIFO, but has many other user-level features (like hooks before/after keypress or release

#

we want a C native library to do the low-level scanning fast. gamepad is the simplest such, but is not general

trim elm
#

Ah I see

tulip sleet
#

gamepad tells you which buttons were pressed since you last asked (it's latching), so you don't miss any presses

trim elm
#

Yeah, that makes sense that you'd want something faster for doing the scanning and then maybe use circuitpython for higher level stuff

#

Oh that is pretty nice

that reminds me, gamepad.py in the adafruit_hid examples should be renamed, it clashes with the built-in one

One possible option - Rename the current branch to "main", then create a branch named "master" or the previous name (in case there's some git guts that is picky about rename & new branch). Then add branch protection so that nobody can push to the "master" branch, then as each guide is updated, delete the old branch name from the repo. Or delete the branch just before updating the guide

Maybe it should output "scan code" like keyboard, just a "byte" per key that you define in advace (like x,y => int).

Here (Belgium) AZ is restricted to only some age range (the older one) because the risk benefits are better there. Also EU seems to not negotiate a new contract with AZ. Thanks to bad reputation of AZ, the vaccine is available to age range that would otherwise have waited much longer. People try to cherry pick vaccine in Belgium, but guessing what center does what, refusing the rendez-vous when they know it is AZ. A real mess.

Most places here in the states openly disclose which vaccine you're getting -- because of the J&J bad press, there's a real strong mindset of "shopping around for the 'best' vaccine". So to save wasted doses, it's made incredibly clear before registering.

[adafruit/circuitpython] New comment on issue #4803: on the problem of esp32 startup and wake up too long

@dhalbert I think the first time is tolerable.

But I'm doing this now, using a GPIO as the development mode button.

import time
import alarm
import board
from digitalio import DigitalInOut, Direction, Pull


_DEBUG = DigitalInOut(board.IO40)
_DEBUG.direction = Direction.INPUT
_DEBUG.pull = Pull.DOWN
if _DEBUG.value:
    time.sleep(10)
else:
    time_alarm = alarm.time.TimeAlarm(monotonic_time=time.monotonic() + 10)
    alarm.exit_and_deep_sleep_until_alarms(time_alarm)...

[adafruit/circuitpython] New comment on issue #4323: Support Sensirion SPS30 Particulate Matter Sensor \(Sparkfun SEN\-15103\)

Hi @kevinjwalters, thanks for reaching out. It seems that creating this issue basically caused my time to work on it to evaporate. However, wildfire season is fast approaching, so I'll prob be reprioritizing.

My interest and work to date have been on the UART side. I think I saw on the SparkFun site the UART interface provided more complete data than I2C, tho I haven't confirmed.

I'm a C++ guy, haven't done much w Python, this was a learning project. I have the Sensirion code tweake...

[adafruit/circuitpython] New comment on issue #4323: Support Sensirion SPS30 Particulate Matter Sensor \(Sparkfun SEN\-15103\)

I'm certainly familiar with the finite amount of time issue! I saw the SparkFun comment too on https://www.sparkfun.com/products/15103 too (retrieved 25-May-2021):

Sensirion has written drivers for both the UART protocol and I2C. Unfortunately we've found the I2C is limited to only mass concentrations (not number concentrations) using the Arduino platform. So if you plan to use this sensor with an Arduino, use the UART interface. Both interfaces are described in their datasheet.

The power cycling is a real buzzkill.

I've got the TFTFeatherWing35 and a Feather RP2040, running Adafruit CircuitPython 7.0.0-alpha.2-646-g7df5d74d9 on 2021-05-22; Adafruit Feather RP2040 with rp2040.

Anything that interrupts the busy loop (filesystem update or Ctrl-C) can trigger the failure state.

When testing PRs I'm trying to make a script so that I remember to do the same setup each time.

Current procedure is:
git clone <pr-authors-repo>
git checkout <pr-branch>

where prtesting is the following script

#! /bin/bash

echo "Creating Python Virtual Environment"
python3 -m venv .env
source .env/bin/activate

[ -e requirements.txt ] && { echo "Installing requirements"; pip install -r requirements.txt; }

echo "Installing generic requirements"
pip install black pylint pre-commit sphinx sphinx_rtd_theme circup

[ -e setup.py ] && { echo "Installing local package in pip"; pip install -e .; }

[ -e .pre-commit-config.yaml ] && { echo "Installing pre-commit"; pre-commit install; pre-commit run --all-files; }

[ -d docs ] && { echo "Generating Docs"; cd docs; sphinx-build -E -W -b html . _build/html; cd ..; }

echo ""
echo "Remember to run:"

@stuck elbow When you have time, could I chat with you about a matrix keypad native module i will be working on? It could be similar to gamepad, or it could be fancier (FIFO, up/down events). The "latching" aspect of gamepad is attractive and simple. This could probably subsume gamepad, and possibly also gamepadshift

manic glacierBOT
idle owl
#

@crimson ferry The 404 links should be gone now. Please let me know if you see them again.

stuck elbow
#

@tulip sleet sure, but I don't really have much to add

tulip sleet
#

hi, thanks. Would you say you are quite satisfied with gamepad's semantics, or do you want more (like a fifo)?

#

i am thinking about how to generalize it to include shift register support, but not sure yet (depends on whether there are too many clocking mechanisms)

stuck elbow
#

I'm fine with the kind of latching buffer it has, because I can only do things once per frame anyways, and the frames come faster than humans are able to click buttons

#

if you compare gamepad and gamepadshift, you will note they are very similar

tulip sleet
#

if you were building a keyboard, would you want the same thing? gamepad is really, well, for gaming.

#

yes, so it would be nice to share code and maybe even an api; could be different args to a single constructor

stuck elbow
#

for a keyboard you want to be scanning a matrix

tulip sleet
#

yes, that's the main step up

stuck elbow
#

I do a very similar thing to the gamepad for debouncing, but then I eventually convert it into keyup and keydown function calls

tulip sleet
#

so my thing would support rows and cols, and maybe report back as a maximum n list of keys that went down since the last call. Sort of like an HID keyboard report but without modifiers, just n keycodes. I think we would not do a multibyte bitmap, since it's more work to extract the key info from that

#

you could specify n, so you would get N-key KRO for that choice of N

#

keycodes would be a combo of row and col #

stuck elbow
tulip sleet
#

i will look at that - thanks

stuck elbow
#

or you could just report the whole matrix, as rows bytes with cols bits

tulip sleet
#

do you use the timestamp?

stuck elbow
#

it really depends on at which point you want to make the cut between the library and user code

tulip sleet
#

yes, i agree

stuck elbow
#

no, like with gamepad, I assume that the time between each scan is enough for debouncing

#

I just have a buffer for storing the previous state

tulip sleet
#

how do you decide it's a bounce?

#

(I could study it; but easier to ask you)

stuck elbow
#

if you did this with pin change interrupts, you would need to store the timestamp

#

but then matrix scanning with pin interrupts would be weird

tulip sleet
#

we were not planning to use interrupts

#

yeah

#

the self.debounce[x] checking looks like it needs to be held down for at least two scans??

stuck elbow
#

yes

tulip sleet
#

i will look at this as a good example of a simple matrix scanner. I will also look at qmk, kmk, etc. I did some searching on github and found less than I expected. Everyone is recycling the arduino library, which has callbacks and other stuff we would not have

#

thank you

stuck elbow
#

well, I ultimately also have callbacks, because that was the easiest way to write the hold/tap logic

#

but that's equivalent to processing keyup/keydown events

tulip sleet
#

yes, that can be done at a higher level

In common_hal_audiopwmio_pwmaudioout_play() we were calling common_hal_audiopwmio_pwmaudioout_get_playing() and common_hal_audiopwmio_pwmaudioout_stop() early on; which means we were accessing the DMA channels before we had set them up by calling audio_dma_setup_playback(). The impact was to stop the DMA for the first PWMAudioOut when setting up the second. In addition, a break statement while checking for a pacing timer was outside the proper braces.

ya, I'd love to see us move the main repo

#

but we could also optimize things better

#

port specific stuff should only rebuild boards for that port

tulip sleet
#

i agree, not sure how easy the "this port only" builds would be

slender iron
#

micropython does it

tulip sleet
#

we just look for the commit filenames only being in certain port trees, I guess

slender iron
tulip sleet
#

do you think the ports_<someport>.yml is good too?

slender iron
#

nah, I do like that we block the board builds based on tests

#

looks like the recommendation is just to short circuit jobs

tulip sleet
#

I'm confused, so they did implement the latter link already?

slender iron
#

no, they do it per workflow

#

we'd probably want it per-job

tulip sleet
#

oh, so we do need to filter

slender iron
#

or we could switch to workflows and always build

tulip sleet
#

if you have a clear sense of what to do, I think it could be done fairly quickly. It would certainly save time. Do we lose some advantage being in a non-paid organization? (like support??)

slender iron
#

I can't let myself get distracted

#

I don't think so because they are generous with public repos

tulip sleet

MANY links would need to be changed if we moved organizations, though maybe there is forwarding

I think there is forwarding

we could do another repo first

I take a look in the https://circuitpython.org/contributing/open-issues, there are some open issue, but there are people working on that already or in the process, I did not see anything that pop out. But I have three different sensors, the MPU6050, the LTR390 and the LSM6Ds (normally acelerometer uses registers). What I do normally is that I go to this list, https://github.com/adafruit/Adafruit_CircuitPython_Bundle/blob/master/docs/drivers.rst and compare with the datasheet. But I do not have a list with the ones that Uses Register, other like the CV class (My favorite hehe). But I think it is ok, you need to adapt on how the library was built, sometimes the sues Struct, others use RWbits, others like to use Buffers, and so on..

I went a slightly different path but it depends on how fast you want the matrix polled,
eg, https://github.com/Red-M/RedPycoKeeb/blob/master/Firmware/lib/pycokeeb/basekeeb.py#L63-L97 This is using the interrupts on MCP IO expander devices but is 10-16ms (depending on if you use I2C or SPI variants of the chips and you'll need the interrupt pins hooked up and level shifted)
but I moved to a Teensy 4.1 and I dropped the IO expanders which gave me a <1ms response time to scan the matrix via just the IO pins of the Teensy (which I've annoyingly haven't pushed the branch publicly yet)

#

more an example of using the int pins to scan the matrix but yes, so much better without them, the only thing I wish the Teensy had was a 2nd core that I could offload LED and screen updates (they take far too long to do due to the shift register nature of the dotstars and the speed of the SPI screen)

#

but the 600MHz core is so lovely to have just for the cycles to always be under 1ms for a matrix poll

#

your .profile automatically adds .local/bin to path if it exists. But you have to source .profile, or just exit the current terminal and start a new one. Try the latter and then echo $PATH and see if it's now in your path

#

.profile includes this:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"

but it hasn't run since you've done the installations, probably

@atomic summit hi we are doing a small cleanup of unreleased boards from the CircuitPython builds. I see the "Unexpected Maker FeatherS2 Prerelease". I'd assume you want to keep supporting this for those that got it, is that right? Do its pins or other features vary slightly?

I think the intent with that lib is, you set CP's idea of the time to the standard time where you are, and use adjust_dst() to add the 1 hour daylight offset during a portion of the year

@tulip sleet are you online?

tulip sleet
#

yup

ionic elk
#

I'm trying to get this PPK2 running and I'm kinda confused by the documentation. Which output wire am I actually rigging to, say, a feather USB pin?

tulip sleet
#

i didn't use it to power USB. I power the battery pins

#

photo coming...

ionic elk
#

hmm, I think my actual problem is I'm not getting the connect tool to put it in "source mode

#

Yeah that's the setup I thought I should have.

#

ok I figured it out something was a button in the UI that I didn't realize was a button.

#

i feed a battery to to VIN and ground, and send VOUT and ground to the board. I was interested in battery-powered consumption only.

So, trying to build CP... what causes "Empty preprocessor output"? I don't se an error in my mpy-cross make

@tulip sleet Great, ok. The docs just refer to the setup of an NRF board - I figured that was probably the setup but didn't feel certain enough to try it

#

@storm minnow sounds like you still have path issues related to the toolchain installation

tulip sleet
storm minnow
#

Ah

tulip sleet
#

why are you specifying a BOARD for mpy-cross??

#

i don't think you mean mpy-cross

storm minnow
#

I didn't?

tulip sleet
#

oh, I misread the above, sorry

storm minnow
#

lol

#

So do I need to do make clean BOARD=circuitpython_express?

#

@storm minnow Do you mean circuitplayground_express?

#

And yes you include the board when doing make clean.

#

I was mostly wondering if that's your issue. Did you type it properly in the command?

storm minnow
#

Yeah, good in the command. Ran make clean without error, building again

#

QSTR updated is all it says, so I feel like that's a good thing XD

#

Oh, some things happening

#

This feels like progress, lol

[adafruit/circuitpython] Issue opened: #4811 Add bits to shift in parameter to GamePadShift

I'd like to request that an additional parameter be added to the GamePadShift API/Module that allows you to define the number of bits to be shifted in. For example, GamePadShift could be used with a Super Nintendo controller if it could be set to shift in 16 bits instead of the default 8:

classgamepadshift.GamePadShift(clock: digitalio.DigitalInOut, data: digitalio.DigitalInOut, latch: digitalio.DigitalInOut, bits: int = 8)

I'd be happy to make the changes myself, but the shared ...

Github trying to bury me :P Not sure if this is one error or multiple? No idea what to do

try pip3 install --upgrade click

#

there is an issue about pip3 not doing dependency versions correectly

storm minnow
#

Ok

tulip sleet
#

what does pip3 list |grep click say?

storm minnow
#

Had already run upgrade, but here's both

tulip sleet
#

actually, tell me the above, and then do pip3 install click==7.1.2, which is a known compatible version

#

pip is not doing transitive dependencies correctly, at least for this

storm minnow
#

7.1.2, check

#

So make clean and try again?

I have built CircuitPython! :D

#

Confirmed working on my CircuitPlayground Express! Huzzah!

@slender iron Are the NeoPixels on a board supposed to reset on soft reset? So if I have LED code running, and then change it to something entirely different and save, should the NeoPixels stay on at whatever the last color was, or should they shut off?

[adafruit/circuitpython] New comment on issue #3264: Refactor PulseOut to not take PWMOut as parameter

That's true, and I agree this is a tricky situation. But just playing devils advocate here, I don't think we have existing precedent for a module tying down resources from an unrelated chip feature just to fit the API, either. If that resource was in abundance, I wouldn't worry about it, but there are only 4 timers on an ESP32-S2, and I don't think it would be that out of left field for someone to wonder why their 4 servo robot is conflicting with their IR controller when Arduino and the IDF ...
