Who has a Neo Trinkey? Do all four pixels on it act as status LEDs? Like CPX etc?
Mine's not here yet.

I'll find out soon enough, but figured I'd ask in case anyone's played with them yet.

Well, all 4 turn red when entering bootloader mode

Ok, that's a start. Can you make a CircuitPython error to see if they do error codes or not? I feel like no. CPX doesn't.

So far the only thing I figured out was to press the reset button 2 times really quick after plunging in to the PC, and changing to USB storage mode (all LEDs turn green). Apologies if was already answered, but I couldn't find any documentation so far.

Hi guys! I've noticed in the module support matrix that i2cperipheral is not listed for Qt Py M0. That means that it doesn't work at all or that it's not included by default?
stuck elbow
it's not included in the firmware, it may work if you compile your own custom firmware with it enabled
bleak heath
I tried searching for the precompiled library but didn't find it
stuck elbow
it's not an external library, it has to be compiled in the firmware

now I need to learn how to compile circuitpython...
jaunty juniper
now I need to learn how to compile circuitpython...
bleak heath
Do you know why i2cperipheral was not included by default on Qt Py? I don't want to compile everything and find out it doesn't work on on SAMD21 because reasons
jaunty juniper
it is enabled on some M0 boards and works, but sacrifices have to be done in order to make Circuitpython fit on really small boards
to enable it you would have to disable other modules
bleak heath
do you know for sure it's a size constraint and not another reason?
jaunty juniper
yup, the M0 boards keep hitting that wall, it's a real issue
jaunty juniper
allright, let me see how it goes
I did a build to see, it fits without disabling anything (with en_US), see if that works
http://www.neradoc.me/builds/circuitpython-qtpy_m0-6.2.0-i2cperipheral.uf2
jaunty juniper
oh yeah that's gonna be slow
bleak heath
your image seems to be starting
let me test i2cperipheral now
if it fits, maybe can be left on by default
ah, and I just noticed that both the board and rpi are missing the i2c pullups
jaunty juniper
that's not a module that has much demand I believe, and it gets complicated because some other languages take more space, which makes it a support nightmare when different localizations don't have the same modules, it's difficult calls
by it fits I mean: 436 bytes free in flash firmware space

I would much sooner remove the midi module

I would make the midi module a library and include i2cperipherals by default keeping in mind that the board has a stemma qt connector
or at least make i2cperipherals a library so I don't have to create the universe before eating an apple ๐
haxpress just means the board has the flash soldered on, right?
jaunty juniper
yes

does it need a special version of arm-none-eabi-gcc?

I would be okay with whatever you think is best. I would love to see them in the main bundle because I think it makes them easier to find and thus more likely to get used. But I can understand that does imply longer term support which may not be something Adafruit would want to do on some of them. Some of them have been used in Learn Guide projects already. The IconWidget is the one that comes to mind it was used (and made for) the Touch Deck project, if any were going to get long term support from Adafruit I would think that may be one.
lone axle
we could move the community bundle to the circuitpython org too
I like that idea. I think it would make it more likely that folks find and use the stuff within it.
oh, maybe I misunderstood. You meant the org on github. not circuitpython.org the web page
slender iron
right, the circuitpython github org
I think I can make a public librarians team there
lone axle
if they do move to a new org, if possible I'd love to get at least one of us to have access to create repos. Especially in the near term there are going to be a few that need to get created in order to split up what's currently in the displayio_layout library.

To me there's no significant difference on what name the files are stored under, it's reasonable to include it in the community bundle. Of course the decision on long-term support is really Adafruit's to make.
My git/github game is pretty weak, so I can't offer much assistance on a transfer. But if you define a place for new things, I will follow y'all's lead.

I know @slender iron and @tulip sleet have been doing a ton of of work on the BLE stack recently (with more to come)... does anyone know if there is or will be a way to connect a single NRF52840 (ideally running CP) to multiple centrals? The use case (from an AT perspective) is that users want to use iOS switch control (which is basically switch scanning for disabled users - from a code perspective it is just acting as an HID Keyboard) with both their phone and their tablet and switch between the two.
So, I guess the questions are:
- Does BLE let the peripheral do this? disconnect and reconnect between centrals?
- Does CP expose it?
- Are there other use cases that put this on the roadmap?
Thanks

At one point I wanted one CP device to act as a mouse for two computer. It is not really the kind of usecase you will find in "simpletest" example and that was trial and error. Also I cannot garantee from time to time I did not have to help one of the PC to connect. I manadged to do it (I need to dig the code) but both PC were receiving exactly the same mouse movement (but it was also the goal as this was a multi-PC mouse jiggler). There might be missing piece of functionality to have fine tune control on the behaviour. The trick that made it work for me (but I recently discussed that here or in meeting) was to re-advertise yourself once the first PC would connect, because by default or in sample code, it stop advertising, blocking the next device to connect.
tough flax
At one point I wanted one CP device to act as a mouse for two computer. It is no...
The only big difference here would be that we'd want to send to one at a time. That is, EITHER you're sending keyboard keystrokes to the iPhone, OR to the Tablet, and you want the CP device to switch between them (without having to change anything on the phone or tablet)
thorny jay
Yeah, I fully understand the usecase.
From memory, when you advertise, you can specify the "name" you use. And actually there was a bit of a mess there, because I played so much with Bluetooth binding, mostly with the same board, that it was hard to have a clean config on the PC side to experiment. But the idea could be to advertise under different name. And when you want to switch, to disconnect and advertise under the other name. So only one "personality" would be visible at a time.
I have physical Bluetooth (no BLE) keyboard that do have multi host, and a button to switch from connecting to one device or the other. But I don't know if it is pure software trick, or if there are separate MAC address or some hardware need for that functionallity.
tough flax
Gotcha - Actually, I kind of like that approach - if the BLE device could advertise "Phone Switch Control" and "Tablet Switch Control" the devices could bond/pair to the name and then internally do the connection switching...
thorny jay
Keep us (me) posted, it is very interesting. I remember one of the issue I had with my code, my code would be stuck on waiting for the first PC before it could advertise with the name known by the other PC. So it would only work when both PC (or at least PC number 1) was present. But I guess I could make the code work better. The idea at the time was the wireless mouse jiggler to keep the PC from going to sleep, and if my CP board was on, I wanted all the PC to stay up. Since I both use my personal and the corporate PC for teleworking... Nowdays I just plug a different CP board on each PC and do that in USB, it solve my problem too.
thorny jay
there's a draft PR, but not done yet: <https://github.com/adafruit/circuitpython...
I think that for what @misty garnet tries to do (and for other to replicate) this will be much easier with a QT Py RP2040 than making a custom firmware for the QT Py (M0) or QT Py (M0) Haxpress.

Hi guys! I'm trying to use regex on a Qt Py M0 but seems the "ure" library is no...
this one is enabled with CIRCUITPY_RE, but you'll need to disable stuff you don't need, I managed by setting CIRCUITPY_USB_HID and CIRCUITPY_USB_MIDI to 0.
I'd say the simplest way to see what is in a build is the support matrix https://circuitpython.readthedocs.io/en/latest/shared-bindings/support_matrix.html
And the available compile flags are in https://github.com/adafruit/circuitpython/blob/main/py/circuitpy_mpconfig.mk
(Micropython modules dropped the "u" prefix in Circuitpython https://circuitpython.readthedocs.io/en/latest/docs/library/index.html)
bleak heath
this one is enabled with `CIRCUITPY_RE`, but you'll need to disable stuff you do...
That's the thing, I didn't find "ure" at all in the support matrix. In the meanwhile I could use beginswith and substring. It's a crappy solution but works for now.
jaunty juniper
yep, it's just re like the C python one
tulip sleet
MicroPython put u at the front so they would have the freedom to deviate from the CPython API. Our policy has instead been to say that our modules that have the name name as the CPython API implement subsets only of those API's

yep, it's just `re` like the C python one

@ionic elk i just did pip3 install --upgrade -r requirements-dev.txt and it fixed some things and caused other complaints, which I fixed manually.
@simple pulsar black said it would reformat adafruit_irremote.py
did your local pre-commit not catch this?

no, because that would require a new commit. You can run the pre-commit hooks locally:
pip3 install pre-commit

pre-commit was really meant to be used locally before you push (hence the name). we are using it in the CI as a double-check

tulip sleet
yes, that was the idea, but they are still pretty close to the regulator
i meant that the sensors themselves may be self-heating due to being queried all the time
simple pulsar
I've seen that on the CLUE's sensors but it's pretty small, like 0.1 or something
tulip sleet
sometimes humidity sensors have an internal heater, for instance
solar whale
I don't usually see that on breakouts.
I'm watching the aht20 slowly rise now -- with the simpletest under CP.
simple pulsar
Have you got it horizontal or vertical?
That house has no chimney, maybe that's the problem
solar whale
@simple pulsar I had it horizontal --- -- just went to vertical
interesting -- when vertical, the temperature is dropping.. slowly
tulip sleet
it is difficult to find a cool spot on the board. The ESP32-S2 module is a pretty hefty power draw, and the neopixels are also an issue, and so is the backlight
simple pulsar
The backllight on the CLUE makes a massive difference. https://forums.adafruit.com/viewtopic.php?f=19&t=175494. You may get some convective cooling if it's vertical, maybe.
solar whale
I was just curious what other's were seeing. It'll take some experimenting -- I was hoping the layout would help more.
My main reason for asking about the board was to see if others had to do the "pre erase" step. I think I had to do that on some other esp32s2 boards as well, but it should probably be noted in the guide...
@simple pulsar looks like it -- I'll have to see if I can turn the backlight off.
simple pulsar
Certainly worth comparing the two scenarios with other parameters constant.
solar whale
quick test -- the backlight clearly has an impact. Lots to explore....

Part of why I'm playing with it. Another reason is that I've been building this sort of board is various forms for about 5 years. Latest was a Feather M4 Express + Airlift + 128x64 OLED.
solar whale
FYI I found that the PIR fit better in the lower set of holes.
I could not get it to go in the upper set
umbral dagger
FYI I found that the PIR fit better in the lower set of holes.
Same. It sticks out SOOOO much. Lower profile would be nicer. I'll be taking the plastic off the header pins to save a couple mm.
idle owl
Is that a cap meant to come off the back of that header on the back of the board, or is it something glued on?
It looks like the cap that comes on the mini SWD headers, but it didn't come off easily so I stopped messing with it.
umbral dagger
It's just a clip to cover the holes.
idle owl
Right, I get that much, but I meant there's something on the back of it, as dastels said, covering the holes.
solar whale
I think it is just not lined up well with the upper holes
tulip sleet
it works from either side, though I think it is a creative use of that connector
idle owl
OK so that bit does come off. Got it.
solar whale
Yes... but probably most useful on the front
idle owl
I suppose convenient if you wanted to mount it on the back, and point the thing into a room and have the display pointed the other way or something.... But yes, most likely useful on the front.
solar whale
Sorry for starting the โobviousโ I misunderstood what you were asking.
idle owl
No worries! I appreciate the response!
The question wasn't that clear because it's not an obvious thing. It kind of blends into the connector if you're not looking for it.
solar whale
I think this board will be fun.
I'm curious about the cap touch slider -- have not tried that yet....
I am not familiar with using one. I assume there is no support for it ...yet other than as 5 pads or is there something out there for it?

Confirmed, same behavior. I tested first with chromium 86.0.4240.197 and it works without a problem, then I upgraded the system and under chromium 88.0.4324.187, the system just froze, I did not even get to new guides, just in learn. Same as you, I did not test SSH stuff (lazy me ๐ณ )
solar whale
@still zephyr thanks! Glad to hear it is not just me!
tulip sleet
@solar whale @still zephyr I reproduced this as well, and did log in via ssh. I was running top via ssh. I opened chromium, went to https://learn.adafruit.com, saw multiple chromium-browse processes appear and then all but one disappeared, and the mouse and screen froze. doing an sudo reboot from ssh did not work; I had to power cycle, as you did. I think it's worth filing an RPi bug or bringing it up in the forum. I don't think we can blame learn.adafruit.com but it's an easy example of something going wrong.

Pardon the ignorance, but working through the weblate list, I came across the string "out must be a float dense array" in the "ulab" library. What, pray tell, is a "float dense array"?
Source: https://github.com/v923z/micropython-ulab/blob/ef65415b5503ae71cc0a9064197f2e3fa5365d74/code/utils/utils.c#L46
jaunty juniper
I think it's a "dense array of floats", and I would translate "dense" as "dense" as in there is no holes in it (ulab arrays can be sparse)
fossil gorge
Dense meaning that there's a value in each element? Such as [1.1,2.2,3.3,4.4] as opposed to [1.1, nil, 2.2, 3.3, nil, 4.4, nil]?
jaunty juniper
in numpy/ulab arrays/matrices can be sparse to spare memory space, meaning they are not coded as a continuous list of values, but with skipped blocks and such
I'm not completely sure of the details, but I think ulab users who know what they are doing will understand the french term dense in this context (or look it up)

Just getting into Raspberry Pi and Arduino after a career in software development. Testing is a big part of my process. How is most testing done? Are there automated tools to help testing?
stuck elbow
no testing in Arduino, on rasperry pi you usually use python, so you have all the usual testing tools available โ just mock the hardware parts
fossil gorge
I'm working through translations, doing some consistency checks and such, and I've come across a few strings in the core that are leading to some confusion...
For example, in the "safe_mode" code, there are references to both CircuitPython and MicroPython. See this last switch block: https://github.com/adafruit/circuitpython/blob/0365755ebd88b0d640aa006a2b9d7a340edefcf4/supervisor/shared/safe_mode.c#L167-L200
Should these (and others) be unified to reference only "CircuitPython",
onyx hinge
@fossil gorge I saw those messages too. I wanted to just remove "MicroPython" entirely
to me the messages read fine still
e.g., "MicroPython fatal error." becomes just "Fatal error"
fossil gorge
They do indeed, but it would seem that to a newcomer or someone not quite aware of the CircuitPython/MicroPython history, might be thrown for a loop.
Good point. Already mentions "CircuitPython" in the entry/header message

I saw one reference about recompiling circuitpython to change the usb defines in some way but it was a bit over my head
tulip sleet
Hi, does anyone know if its possible to behave like multiple usb devices at one ...
Yes, we do this all the time. CircuitPython by default presents a mouse, keyboard, gamepad, consumer control (media keys), mass storage (CIRCUITPY), and MIDI. Some things are missing from some boards for space or hardwrare reasons.

oh ok, so i have this KMK powered keyboard... can i just start using the midi functions if i fiddle with the KMK main loop you think?
kmk is a keyboard firmware

it's better but not vital to have the shared-binding code do the raise instead of the shared-module. Also don't call nlr_raise directly if you can help it: use one of the mp_raise... functions/macros instead

we could also change the test to compare < version numbers instead of version["version"].startswith(this_version) but that's only for edge cases, like if we do a 6.2.1 right now, I believe the RC would stay, since it doesn't start with 6.2.1
idle owl
@slender iron To pop the stack with the discussion from the meeting earlier - if _pixelbuf is smaller than adafruit_pypixelbuf (which I agree it is), why is _pixelbuf turned off for the smallest boards? Wouldn't it make more sense to have it turned on if it's smaller? Or I am misunderstanding something here.
Like QT Py M0 requires adafruit_pypixelbuf to use NeoPixel.
slender iron
@idle owl we can't turn it on if we don't have space. the py version allows us to load it as-needed
idle owl
@slender iron Hmm fair enough.

I thought of a possible case, let me see if I can remember it. Maybe not... I guess unstable releases will always have a suffix.
I think it was like 6.2.1 and 6.2.11, where the prefix is not always before a '-'
we are already using semver anyway, so it seemed easy
jaunty juniper
like right now if we released a 6.2.1 without making a beta first, 6.2.0-rc.0 would not be removed (then again it should not be there in the first place)
but semver would take care of that

@tulip sleet Is it generally okay to use mp_obj_t in the shared-module?
Or is that a "tell me your use case" kind of judgement?
tulip sleet
sure, if you need to, there's a lot of casting there back and forth. Try to find a routine that's like what you want to do.
you use mp_obj_t when you have an object whose type is not exactly known.
Use grep -r or ag to search a typical module implementation for mp_obj_t uses.

yay! It's alive again. yesterday during the meeting I inattentively shorted GND, 3v3 and 5v together by mis-inserting an arduino shield 1 pin off (yeowch). I successfully found the small power supply filter inductor that bravely acted as a fuse, and bypassed it. 
(I also had a spare but this is good)
idle owl
When there's no SPI flash chip (e.g. non-Express board), does CircuitPython live in the same space as the lib and code files?
tulip sleet
they are all in internal flash, which is divided up between the CircuitPython firmware and the CIRCUITPY drive
idle owl
Ok, so that means, the more modules enabled in CP, the less space there is for CIRCUITPY? In this specific situation.
I asked yesterday why _pixelbuf wasn't enabled on small builds when it's smaller than the otherwise necessary pypixelbuf, and was told that we can't turn on _pixelbuf due to space restrictions. And after thinking about that answer, became confused.
tulip sleet
it's not a dynamic choice: on non-Express boards we allocate a fixed amount of space for CIRCUITPY. On SAMD21 boards it's 192kB for CPy and 64kB for CIRCUITPY. so everything, including _pixelbuf has to fit in the 192kB.
tulip sleet
yah, if it were dynamic, then every time you loaded a new build of circuitpython, if CIRCUITPY changed in size, we'd have to erase it and reformat it, which would be a bad experience
idle owl
Ah.
Fair enough.
Another, tangentially related, question. How do I erase Neo Trinkey if there's no storage module.
Because apparently LED Animations is supposed to fit, and it's certainly not doing so for me. So I wanted to try again. (If the answer is something that takes more than 5 minutes to do, then skip it for now, as I was told to move on from this. I'm figuring this will come up though and wanted an answer.)
tulip sleet
we fixed that: https://github.com/adafruit/circuitpython/pull/4595
tulip sleet
but it's not in 6.2
tulip sleet
you can get absolute newst and it will be in there
idle owl
I'll grab whatever off of S3 for now.
Yeah that, lol.
It is not there. ๐
>>> import storage
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'storage'```Also related, is there a way to make it turn off the NeoPixels when you enter the REPL? Neo Trinkey has one status pixel, but four NeoPixels. So if you have code that turns on the LEDs red, for example, and then enter the REPL, one LED turns white out of four, the other three remain red. It was confusing me for quite a while. I imagine it would confuse others.
jaunty juniper
ah storage was added to the other trinkey boards
idle owl

@tidal kiln Ping me when you're around, I have a question about how you feel about whether something would turn into a major support issue or whether it's reasonable. No Canadian rock band. Thanks!
tulip sleet
@idle owl is _pypixel on in trinkey?
idle owl
Yes. As far as I know. Only NeoPixel is frozen in, and using the NeoPixels works without adding any libs.
idle owl
<@!330227457296957440> is _pypixel on in trinkey?
Well Neo Trinkey specifically. I don't know about the other Trinkeys.
_pixelbuf is on, adafruit_pypixelbuf is not frozen in. To be clear.
tidal kiln
@idle owl hey. what's up?
idle owl
<@!330227457296957440> hey. what's up?
Ok. So the Adafruit LED Animation library is large. But there are obvious use cases for it being used on smaller boards. We all have personally simply copied over the animations we wanted to use, and used them as such. But we've never suggested that to users anywhere official, e.g. Learn. Is it going to be a support nightmare to tell folks "Hey, just copy PART of this library over, only the parts you want to use, and then you can use it on any board."? I feel like you'd have a better feel for how this would play out support-wise than I do.
I mean, I guess it would mean documenting each part of the lib, saying "this is what this piece does" and then tell folks to pick and choose based on what they want to do with the animations, maybe? I personally see it turning into an issue where folks never copy over what they need, or they copy over parts of it, and try to run code that uses all of it. And the code will fail.
tidal kiln
"animations" = the code in the library's animation folder?
idle owl
Yeah, but also the stuff in the main adafruit_led_animation folder, not all of it is always needed.
So one could cherrypick from any of the available files.
tidal kiln
i think that would be worth a new page in the guide
"Using on small boards" or some such
idle owl
Right, I agree. But do you think it's even reasonable?
tidal kiln
with a guide page, probably. that's about the best that could be done.

Sounds like there may need to be some tree-shaking going on in circup or the new one (brain keeps yelling 'SUPA-FLY'), so shed any modules that aren't referenced from a library
Not now, but down the road somewhere
deep saffron
Re: circuitpython library slimming.
I've come across a related issue in specifying what resources get installed on which server. There are two approaches that might be helpful:
- Top-down specification of library resource groups or
- Bottom-up scanning of resource groups from libraries
With 1, someone would specify a collection of labels--tags that are over/around the library. A label has a definition, and corresponds to resources you can install. This might be just a subset of the library's files, or there could be some processing of the library itself. Labels can also have their own configuration/schema, and take in parameters that are processed to add more flexibility.
With 2, a scanning program can look at a library, and build a dependency graph from how different modules import and relate to each other. This gives you separable chunks, each associated with a module entry point.
Some combination of these two might let you say things like: "I want the library that is a subset of this library, created by starting with this file, and ignoring these other files or this function definition," or something like "What is the API/docs for the super-slim animation library?"
These interfaces can also be pulled up into a UI with labels/checkboxes. This is definitely an area where there's been lots of work, because compilers and resource bundlers cut out extra code and stuff to slim things down.
idle owl
All excellent ideas!
idle owl
@deep saffron Can you file an issue with that suggestion? Either on CircuitPython and I'll label it libraries, or maybe circup is a good place for it. Basically I don't want it to get lost on Discord.

@tulip sleet what exactly does gc_collect_ptr actually do?

it marks that object and any objects it points to as not being garbage. It gets called indirectly from gc_collect() in main.c

when gc_collect() is done marking everything that is not garbage, it goes through the heap and finds the unmarked objects and says they are garbage and their storage can be reused.
