@slender iron I've integrated Open Street Maps using leaflet.js before and found it pretty nice to work with if you are in JS land maybe give it a look.

slender iron
#

I'm not doing a ton in JS land atm. Most of what I've been doing is integrating more tags into the tiles so we can style based on broadband info

silver tapir
#

I worked on integrating layers to OSM as well. I used to work for a wireless company here in CR, so we made an SVG layer for mapping the AP with the channels, TX power, how wide the antenna is, etc.

onyx hinge
#

the eternal sleep PR? sounds ominous

slender iron
#

nice! I'm actually trying to annotate the OSM features rather than overlaying geometry

#

so marking a building or road as having fiber

#

(or not)

ionic elk
#

@onyx hinge internal. lol

#

revamped the guts of light sleep

#

@onyx hinge will we enable it for any of the higher end ones? Seems like it might be nice for highly specialized C modules

lone axle
#

Nice to see that byte order thing fixed in findimports thanks for working on that Jeff!

onyx hinge
#

@ionic elk I don't know for sure.

ionic elk
#

Or quirky junk that does hacky stuff that wouldn't be appropriate to merge upstream

onyx hinge
#

well .. as it stands, you couldn't receive a pin object in a natmod and do anything with it. For instance. Because you can't call (say) common_hal_mcu_pin_is_free

#

so you can't use it to implement a novel HW driver

#

adding any function to the available functions potentially the compatibility of mpy files too

slender iron
#

we could add that to a list for natmod linking or something right?

ionic elk
#

Can you still you use HAL stuff even? Or they don't have any HAL access at all, just C algorithms?

mental nexus
slender iron
#

I think their IRC might be the most active. let me check...

ionic elk
#

Natmod was a pretty popular request in the past two years of Circuitpython202x blogs so it seems like people had need for it, but if it can't even use the hardware that's... real limited

onyx hinge
#

you can use the functions and objects in py/nativeglue.h

idle owl
ionic elk
#

Could we just add the whole common hal to that file?

#

or does that bork our code size too much

onyx hinge
#

yes probably (I did add one)

ionic elk
#

I mean for big boards, code size isn't a big deal.

fossil gorge
#

Do you mean making the affected libraries into packages, so only the needed functionality is imported?

#

Yes, they were talking about tree-shaking

@onyx hinge @lone axle can the file listing image generator create alt text too? That way the pics would be accessible

lone axle
slender iron
#

I think it does have to be done separately. Dan suggested trying to make the images html and CSS completely instead

#

that'd also make them accessible

lone axle
#

I actually started down that road first, so if we end up wanting that I can maybe re-use some of the code from that first attempt I made. I do think we could generate an HTML file with contained CSS instead of an image. But I don't know if learn guide can embed an HTML page like that? If so that might be a better approach.

slender iron
#

justin would be the person to ask

#

I think it's worth thinking about accessibility of it as dan pointed out internally

jaunty juniper
#

wasn't it mentioned that there's a text version under the picture ? I remember that coming up

still zephyr
#

@idle owl this is from one of my last pr. CI..

#

Collecting Sphinx Downloading Sphinx-4.0.0-py3-none-any.whl (2.8 MB)

lone axle
#

often times there is a text listing (bullet points in my experience) that has all of the libraries listed as text. But I don't know about other required files like images / fonts / sounds etc.. Those are usually mentioned somewhere on the guide but maybe not right alongside the rest of the files that have to get copied to the device.

idle owl
jaunty juniper
#

hmmmm right

manic glacierBOT
jaunty juniper
#

I wonder what the most accessible way is to show files hierarchies, how a screen reader would pick up on a file being indented to show it's in a directory

#

or it would be done by grouping in the html structure

lone axle
#

it's a good question. I'm not sure of the best approach

[adafruit/circuitpython] New comment on issue #2292: How to read from mic on Edge Badge in CircuitPython?

mic = audiobusio.PDMIn(board.TX, board.D12, sample_rate=16000, bit_depth=16)
samples = array.array('H', [0] * 160)

while True:
mic.record(samples, len(samples))
magnitude = normalized_rms(samples)
print((magnitude,))
time.sleep(0.1)

I have trouble understanding. The sampling rate is 16000 i.e. 16000 samples in 1 sec. We create an array of 160 samples only. Can we make the samples array of length 16000 rather than 160? If no, then what's the point of the sampling rate?

[adafruit/circuitpython] New comment on pull request #4722: build a CIRCUITPY\_ERASER variant

The 700ms safe mode window is hard to hit. My reaction time is not that good, and I have resorted to explaining this as a "slow" double-click, since I can't wait for yellow and then click again. Maybe just lengthening it slightly would be helpful. I would love an easier way to get into safe mode.

I'm totally open to increasing the time. It only occurs on power up so it's ok to make it longer. It's actually a hair under 700ms because it's 700 ticks which are just under a ms each.

Ah. As long as it fits in the design guide, yes. I don't want to bloat it with info simply to not have to add a link to the template.

@onyx hinge Do you have a mo? I have two text files I need compared. I used your git ls-files magic to generate them but I don't know how to diff them.

I added the LED pin based on your list, but realised that was generated 2 months ago, and should probably be verified again.

still zephyr
#

@idle owl you need to compare them locally or in github?

Locally. They're two text files I generated locally.

@idle owl I'm back, still want help?

#

seems like you got it worked out

idle owl
#

@lone axle Hmm. If I add a PR template to cookiecutter it will be included with all PRs to all libraries, including Community Bundle libs generated using cookiecutter. There's a way to specify custom templates, but I don't know how it plays into whether or not it would show up, and I don't know if we can utilise it to specify a different template for Community libs. https://docs.github.com/en/github/managing-your-work-on-github/about-automation-for-issues-and-pull-requests-with-query-parameters

About automation for issues and pull requests with query parameters...

You can use query parameters to share URLs with customized information.

#

Anyway it needs to go in, so I'm going to add it, but I'll add it with the intention of adding another one for community libraries so we can try to make that work.

You're welcome!

So, recently something broke all the Python symlinks on my mac and I'm still trying to figure out what it was. But I was disturbed to find that if you update your python installation, apparently any virtualenvs you have will all break? And it's not trivial to fix them either, you have to manually go in and edit them all, or you lose your module list, which is kind of the whole point of having them

#

Is this actually true or have I done something horribly wrong?

idle owl
#

How did you install Python? And what are you using for virtual envs?

ionic elk
#

I don't specifically recall. I have a python3 in /usr/local/bin/python3 which is what which python returns.

jaunty juniper
#

that looks like homebrew I think ?

idle owl
#

I use Pyenv which I think avoids all that nonsense. There's some major issues with Homebrew's Python.

ionic elk
#

I think so too, lemme look up how to figure out how to make homebrew print the location of a package real quick

idle owl
#

I read a post about it recently. Might be exactly what you ran into, I don't remember specifically.

ionic elk
#

Yeah that's the brew python

#

was brew info python

idle owl
#

Oh, the post talks about how if you upgrade any of the dependent packages, Python will be updated also. And it deletes all previous versions every 30 days.

ionic elk
#

I don't know about pyenv, I will check it out

jaunty juniper
#

but I would expect that you need to keep the older version for the venv to keep working, at least by middle version number ?

idle owl
#

Homebrew I mean.

#

Yeah, check out pyenv.

#

There are other options, I'm sure. But having the lack of control that Homebrew offers is probably not good for a stable environment.

ionic elk
#

So this whole brew updates python and screws up all your VMs is just kinda a known issue, then?

jaunty juniper
#

reinstalling the venv with the newest version should be possible with some smart command

idle owl
#

But like Neradoc said, there might be workarounds for your envs.

idle owl
#

Depends on what Homebrew considers "previous" I guess.

ionic elk
#

@jaunty juniper there wasn't one that I could find on google, just a bunch of stuff that said to find ~/.virtualenvs/my-virtual-env/ -type l -delete, which deletes all your modules so it's basically just "delete all your virtual environments and start over"

jaunty juniper
#

maybe something like you recreate the venv but you can reinstall everything by piping some requirements file or something from the old venv into the the new venv's pip install, which can all be automated in a script

#

that's harsh

ionic elk
#

Yeah I could spend a couple hours doing that

#

or maybe not lmao

jaunty juniper
#

I was thinking something like mv venv oldvenv python3 -m venv venv blabla/active cat or find or something ./venv/something/moduleslist | pip install

idle owl
#

@ionic elk Not going to lie, I recently started over because my virtual envs weren't working properly and were all pretty much borked. And it was somehow installing everything outside the env as well. I now use mkvirualenv to create one and workon to open an existing one. I think that's Pyenv. But I had help, so I'm, uncertain.

jaunty juniper
#

but I don't know

ionic elk
#

I'll check out pyenv and see if that helps. If not I will try to spin up a script as @jaunty juniper suggests. But I'm weirded out by my googling, it makes it seem like this is an isolated problem, not something that happens to everybody

#

Otherwise I feel like I'd find more official tooling. Right now I'm seeing a bunch of hacks in my search returns

#

so I still feel like there's something I'm doing that's wrong

#

Anyway TY for help

idle owl
#

Good luck. Hopefully it's not as awful as it sounds.

ionic elk
#

I'm just in the classic "is it broken or did I break it" phase

idle owl
#

Yeah I get it. I always assume it's a me problem for WAY longer than I probably should.

#

And Python environments are a special little flower to begin with.

ionic elk
#

Normally I'd be happy to blame the system but "python updates break all virtualenvs" seems like if it was happening to everybody, it'd be a bigger deal than google is suggesting to me

idle owl
#

From the post I referred to "The web is littered with frustrated reports about this problem and replete with hacked-together Bash scripts that purport to repair damaged Python virtual environments. And all because of one core misunderstanding."

jaunty juniper
#

I did find it unclear with brew if or how to keep older versions of python

ionic elk
#

oh god now my git says there's stuff on my own PR that I put there but somehow don't have locally

jaunty juniper
#

and yeah brew updated me to python 3.9 from 3.8 when installing a different thing once

ionic elk
#

what is this day

#

is my computer invaded with ghosts

idle owl
#

Ghost in the machine.

ionic elk
#

@idle owl ok that post makes me feel more secure about it

idle owl
jaunty juniper
#

somebody had a ghost I2C address in help-with-project too (turns out it's an undocumented but expected thing)

idle owl
#

I need to go start dinner.

#

Have a good evening, folks!

ionic elk
#

In this case I think it's actually just that I merged on github weeks ago and forgot about it

#

whoops.

lone axle
# idle owl <@!382939733107408897> Hmm. If I add a PR template to `cookiecutter` it will be ...

Sounds good to me. Even if it defaults to using the Template for PRs and it's the same one as Adafruit bundle I think that is okay for now. The user could always modify or remove it after they generate their project. Personally I'd probably just leave it for projects I create. I think having that template is helpful for folks creating PRs. A separate template for community bundle would be cool if we can get it to work but not a deal breaker in my mind even if not.

[adafruit/circuitpython] Pull request opened: #4743 Simplify the status LED to save power

This also removes the need to pin share because we don't use the
status LED while user code is running.

The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.

One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.

Fixes #4133

[adafruit/circuitpython] New comment on issue #4632: Pushes to temporary patch branches get uploaded to S3

I think changing all the relevant ifs to add github.ref == 'refs/heads/main' would work to limit pushes without interfering with releases (on 6.x branches for example), but I don't know how to test it:

if: (github.event_name == 'push' && github.ref == 'refs/heads/main') || (github.event_name == 'release' && (github.event.action == 'published' || github.event.action == 'rerequested'))

Is the only cross-screen way to change the background color of a display to use the adafruit_shapes library?

still zephyr
ionic elk
#

I'm just a bit lost in the intersection of all these libraries. I'm setting the background on a sharp memory display - adafruit_shapes works fine, but it seems hacky, so I was hoping to learn the right way if there is one

#

I'm using framebufferio, though, and I don't quite understand totally how that overlaps displayio

#

and I don't see any specific references to background color in the displayio docs anyway

still zephyr
#

Yes, kind of the same.

#

Agree, what normally you do is you create a bitmap of the size of your screen and the color that you want added to a tilegrid and then add append it

ionic elk
#

the display stuff is kind of getting over my head at this point

still zephyr
#

:), you know alarm.c gets over my head, displays stuff is easy 🙂

#

I will ook for an easy example give me a sec

ionic elk
#

I guess my central question is, are there competing systems for display?

blissful pollen
ionic elk
#

because I keep trying examples that seem similar, but they don't overlap

still zephyr
#

so, we are trying to unify all in displayio

#

more recently in displayio_layout

#

but is a work in progress

#

almost there

ionic elk
#

Cool - I don't mean to sound critical at all! I'm just trying to keep up 🙂

still zephyr
#

no it is good,there are different tools, displayio_widget was created to facilitate and integrate all that and avoid having all these graphics libraries everywhere

ionic elk
#

when you say graphics libraries, do you mean things like framebufferio, terminalio, sharpedisplay, that kind of thing?

still zephyr
#

there are some displays that works with displayio and other with frambefferio. and sharpedisplay,

#

when I said graphics I am talking here about the different widgets like the progress bar, the annotation widget, the button, animated button, the text label

ionic elk
#

ok, so you mean higher level libraries

still zephyr

yes indeed

it is clear that is difficult to have displayio in a ssd1306

ionic elk

is it?

sorry if that's a dumb question, what does "difficult" mean? All my example code for testing the 1306 is still displayio

[adafruit/circuitpython] New comment on issue #2292: How to read from mic on Edge Badge in CircuitPython?

Looking at my old code, I think you have to float the old pins too (set as input). I've included some relevant parts below. Please try this and let me know if you still encounter an error. I can clean up what I have (was messily written during a hackathon) and just post the whole thing as a demo. I'd also suggest blowing on the sensor as a means to test it, I found it was the lowest effort method to produce a lot of apparent noise (turbulence).

difficult is because I have not try it 🙂

ionic elk
#

Ok I clearly just need to read the doc pages for all these modules and make a diagram or something

still zephyr
#

I use the display shape library

ionic elk
#

try to understand what does what.

still zephyr
#

I think they are just API for differents thinks made by different people, that is my best guess

#

for faster animations and meory efficiency, low level I recommend vectorio

#

comes with the core

#

if you want the API go displayio

#

But displayio_layout worth a look

#

IT will depend on what you are trying to do I guess

#

Last thing the documentation is excellent in DisplayIO_layout so I recommend read the docs there, but happy to try to answer any question let me now 🙂

Love the generator - I forked it thinking I'd add the strokes as an option, but I see it's already in there as an option. Slightly different approach (current code divides R/G/B by 2 for the stroke - I converted it to HSV and cut the V in half), but it's imperceptible. Yay - I didn't have to fork it 🙂

@gloomy socket that's a good question, I don't see one either.

#

the demo shown in the product page was probably made with arduino

Nice find! I hadn't seen the arduino example

@jaunty juniper I added the LED pin to the remaining Adafruit boards. So everything we support is in line with the change to the code on that page. It's only in main right now though, so until we do a 6.2.x release, we don't have a CP release with those updates in it.

@thorny jay I just tried your mlx90640 code with a feather rf2040 on a keyboard feather wing. I am using CP 7.0 and had to make a few changes to the ulab calls -- after that it works great -- Thanks you! Do you want a copy of the code with the changes I had to make?

[adafruit/circuitpython] New comment on issue #4748: Replacement for sys\.print\_exception\(\)

C python relies on sys.exec_info() and a traceback class missing from Circuitpython I believe, which is why I was worried a C python compatible version for traceback.print_exception would take more space and be more complicated to use. But I might just worry for nothing.

I personally would prefer we implement format_exception()/format_exc() or similar since getting the traceback as a list of strings is more generic and allows for easier piping into logging, uploading to a server,...

@tulip sleet I have an old laptop under 10.12 (!!) it does that thing where the CDC interface name is not in the hierarchy of the serial port, though it has the original pyserial issue that identifying them by locationID is not enough since CDC 1 and 2 have the same locationID, so I can restore that scan function from pyserial as a fallback and maybe find a way to make it differentiate ports

tulip sleet
#

we can also fall back to identifying by VID or VID/PID. I will see whether they really want it to run on High Sierra or whether later is OK.

#

VID/PID does not automatically recognize the right port, but you can always try them both if necessary from the dropdown in the lower right

#

of the Mu window

jaunty juniper
#

hmmm there is a bInterfaceNumber that uniquely identifies each port in addition to the common locationID, that should work

tulip sleet
#

bInterfaceNumber is unique to the total USB device, yes, but is not unique across multiple physical devices (I think you know that. So bInterfaceNumber will not distinguish the data from the repl/console port, but it could help you distinguish the dual ports

jaunty juniper
#

like that:

+-o CircuitPython CDC data@1  <class IOUSBHostInterface...>
| | {
| |   "locationID" = 68157440
| |   "bInterfaceNumber" = 1
| | }

+-o CircuitPython CDC2 data@3  <class IOUSBHostInterface...>
| | {
| |   "locationID" = 68157440
| |   "bInterfaceNumber" = 3

slender iron
#

of course! happy to hear it

#

we do "hug reports" every monday meeting. feel free to drop a note there whenever you have thank yous

#

(link to the notes doc in the pinned messages)

hollow token
#

Will do!
I also may have spotted you on reddit mechkeyboards trying to use IO expanders for a keyboard

#

about 4 years ago

slender iron
#

ya, I used a shift register for one end of it

hollow token
#

What was the poll times like?

#

I'm looking at moving away from the pico to a teensy 4.1

slender iron
#

I never measured it because I didn't notice an issue

hollow token
#

really?

slender iron
#

I think I2C is likely your bottleneck

#

I2C is slow

hollow token
#

hmmm

#

I have the SPI MCP23 chips

#

and they're slower

#

my I2C ones are ~10ms a poll vs 16ms

slender iron
#

the shift register was used to "bubble" the low value through

hollow token
#

and the SPI bus is at 10MHz

slender iron
#

16ms for a full scan seems fine

#

that's 60fps

hollow token
#

yeah I haven't gotten my shift register boards in yet

#

this is all on the MCP23 chips

slender iron
#

why do you think that's too slow?

hollow token
#

I'm aiming for sub 1ms though

slender iron
#

why?

#

your monitor likely updates at 60hz and you won't see the intermediate key state

#

humans can barely perceive 60hz

hollow token
#
  1. To see if I can do it
  2. Because commercial boards claim to be able to do it so I'd love to make something that actually does do it and you can verify it
  3. I like to set a high bar to see what is possible
#

I also have 144Hz panels

slender iron
#

USB is 1000hz I think

hollow token
#

my only 60Hz panel looks slow to me these days, even just dragging the mouse around

#

I know it can't actually provide reports faster than 1ms

slender iron
#

a logic analyzer may help optimize the code

#

since that'd let you see all of the bus traffic

hollow token
#

errrr iirc, its that setting the row pin low takes too much time

#

because its all on the MCP23

#

so the 24MHz serial shift register should make that non-existant

#

but I think the teensy will be better since I don't have to deal with IO expanders at all and just some level shifters for the dotstar "SPI"

slender iron
#

how many rows and cols do you have?

#

the pico has lots of pins

hollow token
#

21 cols, 7 rows

#

I literally cannot fit it on the board

#

I could do it with the shifter register but I'd have no pins for the dotstars or screen

slender iron
#

how many total keys?

hollow token
#

112 iirc

slender iron
#

do you have a logic analyzer?

hollow token
#

nah, haven't gotten around to it yet, but I may need that tool

slender iron
#

it could help ensure you are doing minimal transactions

#

they are super handy for optimization

storm minnow
hollow token
#

iirc, I found someone else doing the same thing and I tested their poll code on my set up and they were ~20ms on my I2C chips vs my 10ms

#

I set the row pin then see if any of the interrupt pins are high, if the interrupt pin is high I ask the chip for that bank's interrupt flag register output then register the key press if the IO register in the MCP23 for that MCP23 pin being high then I report that key via the keymap and reset the flag for that bank to return the interrupt pin to low, then move onto the next row

#

I have a logitech G700s mouse that says it does 1000Hz reporting

#

I think my ducky keyboards also claim a 1000Hz report rate too iirc

storm minnow
#

Are you looking to build your own gaming keyboard/pad?

hollow token
#

Yeah, I was wanting the pico mostly for the novelty plus the 2nd core would be good for LED animations and screen updates. The screen is for the numpad "layers", so you can what the numpad is mapped to, to be used as an optional macropad.

#

Also because the name Pyco (python and pico) for a full size board is like calling a guy who is 7 foot tall "tiny"

storm minnow
#

Sounds cool. If you're not playing a lot of FPS stuff tho, might not need to worry about polling rates

hollow token
#

Haha, my favourite games are FPS :)

storm minnow
#

Kinda important then XD

hollow token
#

Yeah, doesn't help that I'm a huge mechanical keyboard nerd too and that I plan to sell kits at some point, so I not only want it to be good to use for myself but something that I can have other people use too. I'm open sourcing all the hardware and firmware but the kit option is there for people who don't want to get boards fab'd and don't have the tools to do it themselves.

@tulip sleet looking at that issue just above, it seems that HID and MIDI are disabled on stm32f405 due to lack of endpoint descriptors (there are 4 in+out pairs). With 7.0, can we enable it but .. I guess the user would have to disable CDC or MSC before turning on HID or MIDI? Maybe you'd like to comment, or maybe @ionic elk can say more about the HW limitations.

#

The OTG_HS in peripheral mode has 6 in+out pairs, but I guess it's the OTG_FS peripheral that CP uses.

tulip sleet
#

I was just responding to that as you wrote. I'm not sure whether there are 4 or 5 available endpoint pairs. I need to double-check that. I have a provision for leaving HID, MIDI, etc, disabled by default, but if there is room one of them could be enabled.

#

so we could compile them in, but you might need to turn off CDC to HID, etc.

onyx hinge
#

The OTG_FS interface main features in peripheral-mode are the following:

  • 1 bidirectional control endpoint0
  • 3 IN endpoints (EPs) configurable to support Bulk, Interrupt or Isochronous transfers
  • 3 OUT endpoints configurable to support Bulk, Interrupt or Isochronous transfers
tulip sleet
#

so one pair for MSC and 1.5 pair is needed for CDC REPL

#

and then they are all used up

#

I will query the user about this; not having REPL is a nuisance, but is possible

#

I think the OTG_HS does not have a PHY

#

ok, yes, it does have a PHY, but it's not wired up

onyx hinge
#

yes, the OTG_HS has a FS-capable PHY; but it's not connected on the feather

tulip sleet
#

i think it's not connected on the pyboard either

#

i'm not sure why we chose the FS instead of the HS. I think TinyUSB does support HS, but maybe there was some other reason

    0x0304, 0x0409,

I guess that character is 0x409

tulip sleet

yes, I forget the exact interpretation of 0x0409 as a language ID; I think it might mean "no language specified"

[adafruit/circuitpython] New comment on issue #4752: STM32\(F4\) USB HID support

USB HID (and MIDI) are theoretically available, but they are not turned on. The problem is that the USB physical interface (PHY) that is connected to the USB connector only has 4 endpoint pairs. One pair is reserved for control purposes, one pair is used for mass storage (CIRCUITPY), and two pairs (well, 1.5), are used for the CDC serial (REPL connection). So that leaves none for anything else.

There is another USB PHY on the chip, a HS-capable one with more endpoints, but it is not connec...

#

since that script is all gone in master I won't worry about fixing the weird character.

tulip sleet

that was autogenerated anyway; it wasn't checked in

Hi, I've just noticed an issue with garbled data in ulab. It looks likely to be related to taking a slice of a returned array (which is a view) but not storing that unsliced array anywhere. I'm just going to go rummaging in github issues...

It's good, and I'm not sure how else to name at least one of them.

seesaw is older.

I figure if we're going to approve new code, we might as well try to stick with newer decisions, regardless of the current code.

Anyone have one of these STEMMA rotary encoders and a Raspberry Pi set up?

That's fine, if your bash doesn't have global it probably stays persistent. It carries into new shell sessions. Just figured I'd check if you happened to know.

[adafruit/circuitpython] Pull request opened: #4754 Fix endpoint checking; Clean up safe mode printing

Fixes #4746.

  • Endpoint count checking was off by one.
  • CIRCUITPY_USB_{HID,MIDI,MSC}_ENABLED_DEFAULT default values were not set conditionally.
  • Clean up print_safe_mode_message() to simplify logic, reduce size, and divide up safe-mode reasons more accuractly.
  • Redo logic of printing startup messages in run_code_py() to not print safe-mode message twice, clean up newlines, and be more consistent about whitespace.
  • Shortened and rephrased some messages slightly.

@Neradoc It turns out the ESP32-S2 endpoint situation is idiosyncratic. From the datasheet:

  • Endpoint number 0 always present (bi-directional, consisting of EP0 IN and EP0 OUT)
  • Six additional endpoints (endpoint numbers 1 to 6), configurable as IN or OUT
  • Maximum of five IN endpoints concurrently active at any time (including EP0 IN)

All the other chips have symmetric pairs of IN/OUT endpoints, but the ESP32-S2 does not. I am confused why we can support HID at all, because t...

[adafruit/circuitpython] New comment on issue #4752: STM32\(F4\) USB HID support

There is another USB PHY on the chip, a HS-capable one with more endpoints, but it is not connected to anything. It is not connected on the PyBoard either. I'm not sure why, but I think there was some reason.

Most of the STM chips have HS peripherals but no HS PHY. They require a separate UTMI chip for the HS PHY. That's why they aren't used very often.

There actually don't seem to be that many changes in the core language syntax. 7.0 will have expression-assignment ((x := f())), variable type annotations (x:int = 1), and matrix multiplication operator (A = L @ U). That's about all I saw reading through the top blurbs of the related micropython releases..

#

it'd be nice to have variable type annotations for use in libraries, but we'd only start using it when we no longer make 6.x bundles. Well, the same for any of these features really.

@kevinjwalters

That would be inappropriate as the slice is a view onto that data as I understand it.

This is correct, but perhaps the first question is, whether this has anything to do with ulab, and convolve. I believe, especially, if this is a problem with the garbage collection, we should strip this to the most trivial example that produces such behaviour. Something like this:

but the board did reset, and when I was able to connect again (it did not re-reset), it was NOT in safe mode. So that would explain the reset loop. It is not going into safe mode successfully with the UF2 version

#

it just keeps running boot.py over and over, which causes the reset loop

#

this safe mode issue sounds familiar, maybe there is already an issue for it

jaunty juniper
#

ah

tulip sleet
#

in any case, needs to be investigated. I will write an issue

#

i never use the UF2 because it's too easy to mess up and then you need esptool anyway

jaunty juniper
#

yeah I remembered that, I thought it might be the difference 😉

tulip sleet
#

i will try that again to verify and hopefully I will not crash Linux again

#

verified, it did not go into safe mode

#

and fortunately it did not crash this time. Linux has some kind of problem about not liking the CDC connection being terminated abruptly

jaunty juniper
#

yep I can confirm it doesn't go to safe mode

tulip sleet
#

i'll confirm safe mode restart works ok with the .bin...

yes, it does

7.0.0 latest, with TinyUF2 in use only.

ESP32-S2 does not go into safe mode when requested to do so on a reset.

>>> import microcontroller

This would be a problem for people using the RPi Pico, as it does not have a reset button?

[adafruit/circuitpython] New comment on issue #3410: RFC: routines for handling wrapped tick counts

I thought about this, and propose adding a simple new native-C module interval. Its implementation will be very small so it can fit on the smallest boards, which don't have longints. Because it only uses short ints and is not a class, it generates no garbage, and is fast. Pseudo-code is below:

interval.py:

"""Time intervals < 2**30 milliseconds (about 298 hours)."""

MAX_MS = 2**30 - 1
"""Maximum available interval: about 298 hours."""

[adafruit/circuitpython] New comment on issue #3410: RFC: routines for handling wrapped tick counts

@dhalbert I think that's fine, it has a slightly smaller "surface" than mine but is a bit "more different" from the micropython implementation.

To allow implementing micropython's ticks_diff and ticks_add with a minimum of fuss, consider making the wrap occur 229 rather than 230 (and do put the wrap value in the public API):

the TICKS_PERIOD of 2**29 is chosen to simplify the backwards-compatibility implementation of ticks_add and ticks_diff on platforms without long ints; we can ...

[adafruit/circuitpython] New comment on issue #3410: RFC: routines for handling wrapped tick counts

I worked interval out from scratch while not being able to sleep, without reference to the MicroPython utime routines. The first thing I thought of was has_elapsed_ms(), and added diff_ms() later. I didn't realize how close it was to utime. My diff_ms() does not return negative values (it always assumes there might be a wrap) and does not depend on utimes TIME_PERIOD/2 constraint. I think that it is a little less confusing.

Is there a way to create an operation similar to findall using the re module? My re experience isn't great, I could do something to whittle down my string with each match but maybe there's a better way?

ionic elk
#

well, I guess cutting the string isn't so bad, actually, pretty concise.

onyx hinge
#

standard python lets you specify a start position for the match and search methods of regular expression objects: ```python

re.compile("x.").match("xaxbxc", 2).group(0)
'xb' # standard python3

this is optional in CP/MP but looks like we enable it whenever we enable re. (except not in the "unix" build which is what I initially tested)
ionic elk
#

@onyx hinge ok, so instead of cutting the string, I'd just change the match start? That'd work too

@steel granite the asf4 submodule has files from microchip. one step of adding saml21 would be obtaining the files and adding them to a fork of https://github.com/adafruit/asf4.git

@steel granite normally the linker is told it must include all symbols in the special section called ".vectors", and every other function which is required (such as main()) is found, directly or indirectly, from those functions. I would guess that ".vectors" does not have right contents (any contents) for some reason.
boards/common.template.ld: KEEP(*(.vectors)) /* isr vector table */
For samd21, this is the startup_samd21.c file in the asf4 files for samd21: ```c
samd21/gcc/gcc/startup_samd21.c:attribute((section(".vectors"), used)) const DeviceVectors exception_table = {

so I'd make sure `startup_saml21.c` is included in the list of source files and has the appropriate content. 
```make
Makefile:       gcc/gcc/startup_$(CHIP_FAMILY).c

I've spent a fair amount of time attempting to understand how my Raspberry Pi Pico works.... I've barely scratched the surface. Thus far I've been able to get some "neopixels" running some basic algorithms, such as a walk from (x1,y1,z1) to (x2,y2,z2) these can be pre-determined coordinates or randomly generated to create really fun color effects.

[adafruit/circuitpython] New comment on pull request #4689: Dynamic USB descriptors

From my understanding, that slide position check and the disabling of USB descriptors needs to be in boot.py after you re-plug the board in.

So indeed boot.py is needed, and I was confused because the output of boot.py are in boot_out.txt.

It is very hard to troubleshoot and understand what is happening... but I also need to convince Windows 10 that the filesystem is clean. Any ejection when CIRCUITPY is visible make this trick stop to work for me and the drive keep reappering. ...

[adafruit/circuitpython] New comment on issue #1439: Add support for multiple virtual keyboard devices for N\-Key rollover

This missive is interesting: https://www.devever.net/~hl/usbnkro.

The 6KRO limit is if the device is recognized as a boot keyboard only. So there are a couple of ways to achieve NKRO: one is to use a >6-key report descriptor, and another is to simulate multiple keyboards.

TinyUSB allocates the number of separate HID interfaces at compile time (also true for other devices, such as CDC). Currently we allocate only one. I will make this at least two to be able to support boot keyboards. Bu...

It would actually be very handy to have a way to assign a 6KRO for the first USB descriptor then another descriptor as an NKRO to allow for NKRO when inside an OS but to also allow for boot time control.

This will be possible. You will be able designate a keyboard (or mouse) descriptor as "boot", and it will mark it as a boot device. You could have a completely different keyboard report descriptor as the actual report descriptor (which would would be ignored in boot mode). So you could us...

[adafruit/circuitpython] New comment on issue #1439: Add support for multiple virtual keyboard devices for N\-Key rollover

I thought that the host is supposed to tell the device whether it expects a boot keyboard or not when the plug is connected?

The host sends a "Set_Protocol" command to switch to the boot protocol and the standard, implied descriptor. So I think you could still have an NKRO-style report descriptor, but also will need to support the standard descriptor if it's Set_Protocol to boot mode. I think this is implied by the spec and by the last few paragraphs in https://www.devever.net/~hl/usbn...

I think it should be the other way round: If something is wrong with boot.py, the filesystem should be always writeable so you are able to fix the error.

Renaming boot.py via REPL didn't work but formating the drive resets it completly.

I think it should be the other way round: If something is wrong with boot.py, the filesystem should be always writeable so you are able to fix the error.

If the filesystem is corrupted, then the metadata is probably damaged (e.g., the directory entries). It can't be recovered, so we or the host computer make it read-only so no worse damage will happen.
