@slender iron since gamblor reviwed #3532 is there anything else you're looking for at the moment?

slender iron
a quick glance would be nice and then an approval
atomic summit
@slender iron you closed my issue, but I think it's incorrect, sorry.
When I use 4MB flash, it doesn't reload code.py when the OS mounts
It only does it when I use 16MB flash.
so it can't be the correct behaviour
slender iron
let me try on my saola with 4mb
atomic summit
ok
slender iron
do you have any samd boards you can compare against?
atomic summit
Yup,doesn;t do it on my CPX or ItsyBitsyM4
and doesn't do it when I flash my FeatherS2 with 4MB
slender iron
do you have any non-mac devices
atomic summit
And Mark Olsen also sent me a video of it not doing it on his Soala Wrover, on his Mac
slender iron
this is a super minor issue
atomic summit
Minor for every board not suing 16MB of flash 😉
slender iron
running a second time has no consequence
atomic summit
other than more support work for me to explain to people why 😉
hahaha
I also still get the 5 second boot time.
soala gets < 2seconds
So there is something fishy going on.
slender iron
it may be due to ram blanking or something
stuck elbow
I wonder if it's the macosx writing to the disk a second time when the disk is bigger or something like that
atomic summit
it's going to be an issue when deepsleep is available and folks want to use any boards with large RAM for battery projects.
stuck elbow
no idea if there is something like iotop for macs that would let you see writes?
slender iron
@atomic summit we don't support deep sleep in circuitpython currently
atomic summit
I know... that's why I said "when available"
slender iron
👍
atomic summit
It's a super common use for ESP32 - IoT battery projects
so extra boot time will just drain batteries faster 😦
But I guess that issue is for another day 🙂
@stuck elbow Not sure either.
stuck elbow
@slender iron would it make sense to delay autoreload if it has just reloaded/started?
manic glacierBOT
slender iron
@atomic summit we'll get there eventually
@stuck elbow the current behavior doesn't bother me and I'd worry about ignoring any writes because they could actually be user triggered
stuck elbow
oh right, you would have to ignore them, not just delay
otherwise you get even longer "boot time"
@atomic summit if you care about battery in your project, you can always disable autoreload in your code
atomic summit
@stuck elbow Can auto-reload be changed by the user in code? Or only at the firmware level?
stuck elbow
it's runtime setting
in the supervisor module, IIRC
but it would probably have to be done in boot.py to happen before USB gets mounted
stuck elbow
hmm, I can't find it now in the docs
supervisor.enable_autoreload() and disable_autoreload
atomic summit
so that goes into boot.py?
but then a user can get their code to reload unless they connect via serial and send a ctrl+d ?
thorny jay
off and on again or reset ...
atomic summit
I guess ultimately no matter if it's a CPY specific issue or something OS level, it's a crappy user experience to have it happen, and also a foreign experience for those already using CPY.
@thorny jay a hard reset is a terrible way to get your code to restart as it forces a disconnect and remount of the USB.
It's fine on a board that doesn't have USB mounting.
thorny jay
If I code, I have Mu and the terminal window is build in.
stuck elbow
@atomic summit your code can re-enable autoreload if it determines it doesn't want to go to deep sleep
@atomic summit your code can re-enable autoreload if it determines it doesn't want to go to deep sleep
and if it does go to deep sleep, it restarts anyways
atomic summit
Sure, but again, a totally foreign concept to code for, for those experienced in CPY to have to do.
stuck elbow
it is an advanced thing
atomic summit
hahaha... or a "work around" thing 😉
stuck elbow
circuitpython is for beginners first
it's fine if you need a workaround for not being a beginner
thorny jay
Can I unsolder the 16Mb and put a 4Mb? 🙂
atomic summit
Right... so to explain to a new user why bard A does this... but board B does like this.
thorny jay
I will solder a 4Mb(?) on a QT-Py...
atomic summit
Right... so to explain to a new user why bard A does this... but board B does this.
thorny jay
It's magic.
stuck elbow
they both do this
atomic summit
Or more specifically, board a,b,c,d,e,f,g,h does it like this... but these few do thinsg differently.
stuck elbow
it's just your operating system that decides to do something else with the bigger filesystem
thorny jay
Did you try the Mac tricks: https://twitter.com/todbot/status/1312632671453863936?s=20
stuck elbow
@atomic summit the whole argument is moot, because you don't really care about baterry power when connected to usb anyways
@atomic summit the whole argument is moot, because you don't really care about baterry power when connected to usb anyways
and it doesn't happen when you are not connected
atomic summit
I'm not talking about battery use stuff..
what if I am running code that logs every time it starts up..? I get dbl logs every boot when connected to USB
stuck elbow
I thought you were worried that the restart would cause more battery use?
atomic summit
I am... but that's for a later date when deep sleep happens
stuck elbow
well, you will get double logs every time you change any file anyways then
atomic summit
for now, it's about "this board does something different to every other board" and that's a bad user experience in my mind.
right, when I am deliberately changing code.. which is different to just plugging it in.
bad/confusing user experience
stuck elbow
there is no difference at the block device level, a write is a write
shame you can't send a pull request to Apple to make it stop doing that
atomic summit
Ok, I am now getting it to do the restart code.py even on 4MB flash builds
so it's not 16MB specific
I deleted all of the hidden files macOS adds
and now every plug in, it dbl runs code.py
so it's not a flash size issue
or more specifically a partition size issue
stuck elbow
does that trick @thorny jay linked to help?
atomic summit
oh, I missed that link
I'l try a bit later, need to get back to renovating my garage
thorny jay
There are actually two tricks (that might be identical) one from the original tweet and one from Adafruit I linked to.
I have the feeling that I already had double reload, but I cannot tell on what board, with what computer and what version. At one point I felt it was just an anoyance, but could survive that.
stuck elbow
at least it doesn't remount on reload, or you would have a loop
but there are some disk checking or antivirus programs that completely waste circuitpy drives
thorny jay
Nowdays I make my own double reload, because I use main.py that import my application. So when I go to another version, it reload (I copy my app), if I import another app, it reload, if I add a library, it reload.
So all in all, it reload a lot.
The waster was an old version of Mu that wanted to install demo image/sound/... that was a nightmare when using non express board.
atomic summit
Ok, so if this is all stuff folks working with CPY on a Mac are used to, then my concerns are moot, and I'll just accept it as expected behaviour and stop annoying folks about it 🙂
I'm still very new to CPY so don't have a lot of my own "use case history" to leverage.
Thanks @thorny jay and @stuck elbow for your insights and to @slender iron for looking into it for me.
supple gale
I modified one of my esp32s2 boards, removing the 4MB flash and soldering in a 16MB one. No PSRAM. Windows, no reload, Linux, no reload, MAC OS, reload. My code.py is just a routine that cycles a rgb led. Its pretty fast as there is no PSRAM to test but you see the rgb cycle stop then restart.
supple gale
Yes, bult two versions, and loaded on the same hardware, only diff is the flash chip. And the flash size setting. Its interesting. Super time waster but its pouring rain here today.
teal bear
time wasters are fun 😉
supple gale
The setting in this case is in the boards directory, mpconfigboard.mk
CIRCUITPY_ESP_FLASH_SIZE=16MB
For some reason on MACOS the board is being detected as a keyboard and is being probed? At least the error message comes up that the attached keyboard is unusable.. Doesn't happen with the 4MB flash version.

Hey all, using circuitpython on a QT py with 6.0 beta. I thought displayio was native but I keep getting "Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'displayio'"
supple gale
I believe you need to install the adafruit circuitpython bundle
https://learn.adafruit.com/adafruit-tft-gizmo/circuitpython-displayio-quickstart
Shows you how. Basically copy what you need to the lib folder on the CIRCUITPY drive
Thats not specific to the QT py but should be similar
steady coral
yeah that's the problem I have the library and I've tried bus_device, display_text, and displayio_ssd1306
low sentinel
displayio itself is a module that comes from core circuitpython C code. It is conditionally enabled in the compilation per-board. SAMD21 / m0 boards frequently have it disabled because the extra bytes it takes to compile into the firmware image is too much.
crimson ferry
You can add a flash chip to the QT Py, and use the QT Py Haxpress .UF2
steady coral
ouch...well that sucks. Thanks for the help though. The chips were out of stock when I bought the qt py. Does the Haxpress have it enabled by default on the firmware?
crimson ferry
steady coral
aaaaaah
maybe I can compile my own firmware and remove some of the other modules I won't use... 🤔 haven't done that yet
sounds like fun if I can do it lol
manic glacierBOT
thorny jay
ouch...well that sucks. Thanks for the help though. The chips were out of stock when I bought the qt py.
@steady coral Ok, so I have feature request for @river quest that can increase sale. I want to be able to make a basket, put out of stock product in, then get a warning or automate my purchase when all the product I want can be put in the same shipping. I had 4 product I really wanted, but I had to wait weeks before 3 of them became available simultaneously. And this is only possible if once they were available and you could add them to your basquet. Adafruit could figure out... if we produce this piece, then those 10 basquet can be fullfill and we will satisfy those order.
manic glacierBOT
blissful palm
The setting in this case is in the boards directory, mpconfigboard.mk
CIRCUITPY_ESP_FLASH_SIZE=16MB
@supple gale I am not sure which board you are talking about but I seem to remember seeing 'USB_DEVICES = "CDC,MSC,HID"'' in the Feathers2 mpconfigboard.mk a while back which confused me..
supple gale
@blissful palm Its actually a Stetelthings MAIA which is another ESP32-S2 board. No PSRAM. And yes I wondered about the USB_DEVICES and thought it was a copy from the original espressif_saola_1_wrrom/wrover config. But I dont see that there. And searching only see it on two board configs. I will remove it and see if that please MAC OS.
I am guessing that this is some sort of timing difference between the boot. And MAC OS seeing something, checking if its really a keyboard, then code.py reloads (as it should). Not having a USB sniffer and not being anywhere close to my area of expertise I leave it there. I
supple gale
@blissful palm Recompiled without the USB_DEVICES. Still get the double reload on MAC OS.
atomic summit
I've been doing a bit more testing and used these steps to clean up the filesystem on the device https://learn.adafruit.com/welcome-to-circuitpython/troubleshooting#macos-loves-to-add-extra-files-2978466-45
And though it didn't stop the code reload, it did reduce the boot time from 5secs to 3secs
I'm a little perplexed as to why the boot time would change with these filesystem changes.
thorny jay
Obviously your MAC is doing things...
atomic summit
As that would suggest the OS is doing something once the USB is brought up during boot that is holding up the boot?
@thorny jay Yeah, sure, but I'm curious why it would hold up the boot process.
thorny jay
I still have 4 weeks to wait before I can help you with the FeatherS2. 🙂
atomic summit
Sorry 😦
post really sucks atm 😦
I also tried removing USB_DEVICES = "CDC,MSC,HID" due to the discussion @supple gale and @blissful palm were having but that make no difference either
This is still on the version from yesterday pre analogin
going to play with that later today
thorny jay
You could also play with remounting the file system as writable from CircuitPython (and that is automatically not from the host): https://learn.adafruit.com/circuitpython-essentials/circuitpython-storage
It is something you put in code.py to be able to log on the flash, that is normally not writable from the CP side.
I am totally unsure this would have any effect on boot time... but it could stop the MAC from beeing able to access in read/write.
atomic summit
Yeah, but that also prevents folks from being able to write to the USB to copy code on without either doing the IO hack, or having them alter the boot.py via code to disable it.
stuck elbow
you can boot it in safe mode to disable it
not sure how that's done on the esp, on other devices you just press reset while it's booting
then it doesn't execute your code, so it mounts r/w
also, I don't think it's holding up the boot, it just makes it restart before it finishes booting
supple gale
This is the boot video. Build from today. It boots very fast, probably because it no PSRAM. You can see the code.py reload. Note it doesn’t reload twice if the Mac is logged off.
wise shard
I have another noob question. I am trying to modify circuitpython and I am on the right track but is there a way to see prints in a console once it is compiled and installed as the boot loader?
I have largely made changes blindly by reading the code and fixing compilation errors but I need to debug a bit.
stuck elbow

stuck elbow
yes
stuck elbow

I am updating a shared module (shared-module/_stage/__init__.c) but it doesn't seem to build my changes when running make. confirmed by adding nonsense to the code and it compiles successfully. Not sure what to do.

Hey all, just looking to be pointed in the right direction. I am compiling new firmware for the QT Py, so that I can add displayio (it is in the haxpress firmware but not the regular one). I have a list of frozen modules but I do not see one for DisplayIO. Is there another location where I can find something like Adafruit_CircuitPython_Displayio?
Frozen module list:
stuck elbow
@steady coral displayio is a built-in module written in C, you would enable it in the makefile for the board you are compiling for
for example, here is how it is enabled for the ugame10 board: https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/ugame10/mpconfigboard.mk#L19
steady coral
I noticed that the firmware for QT Py (standard version) has USB_MIDI and I wanted to disable this to free up some stuff to add DISPLAYIO, so I tried CIRCUITPY_USB_MIDI = 0 in the mpconfigboard.mk file but the compiler says: undefined reference to `usb_midi_module'
steady coral
[Makefile:408: build-qtpy_m0/firmware.elf] Error 1
I see what you mean though: firmware.elf.lto.o:(.rodata._usbd_driver+0x54): undefined reference to `midid_init'
I thought I could just disable it with = 0 but it's referenced...
steady coral
no let me try that
👍 nice! That worked. I am getting closer, I was able to free up about 5,000 bytes haha...now I need to disable some more stuff so I can fit it on 🤣
USB midi, touchio, and USB HID took it from somewhere in the 30,000 overflow to 25,000 overflow
stuck elbow
if you don't need analogio, it's rather big

Is there a practical way to isolate/hide the code files that run on CP away from the other files that appear to the user when a board is connected to a PC and shows up as a storage device?
timber mango
Longshot ask here: Is there an audio library that allows me to turn different notes/frequencies on or off on the fly? Example: Piano consisting of 10 keys, and when a certain key is pressed, play a certain note/frequency. (That part is simple, works well) But if two buttons are pressed, play the two associated frequencies -- and when a button or buttons are pressed, stop playing the associated notes. Would be nice if there was a library to do this, so I don't have to reinvent the wheel. Seems like a common situation, but can't find many resources covering this. (Chords)
stuck elbow
@timber mango there is a mixer module that lets you mix several sounds together
honest dust
It also depends on how you're going to play the sounds. Digitally it's easy to mix two sounds. But if you're using piezo buzzers with PWM (for example), you will need multiple buzzers to play more than one note.
timber mango
To be clear, I'm looking for generated tones, not samples. And it'll be output from the board straight to headphones.
stuck elbow
you can generate samples
honest dust
And if you're not going to generate samples / digital audio, the solution depends on how you're planning to generate the sounds.
blissful pollen
@timber mango Jon Park did a tutorial on making a teletype audio input that did something similar: https://learn.adafruit.com/clue-teletype-transmitter/overview
timber mango
It doesn't need to be super high quality. It's for a musical trainer, not a performance level project. I'm using Arduino and tone() right now, which is working well, but I'm considering moving over to CircuitPython and looking at audio libraries. Speed is an element, as well, since you want key presses to be non-delayed.

I took a little time to test evezor's canbus featherwing with adafruit's feather stm32f405 express. @teal bear provided me with a free sample.
It works! My test was pretty quick and simple, with the stm32 as the receiver and a prototype Adafruit Feather M4 CAN as the sender.
Suggestions about the featherwing, which you should feel free to take with a grain of salt:
- Offer a 0.1" pitch jumper for the CAN H/L lines
- I do like the pass through connector concept though, I just didn't have the parts on hand to use it
- For better feather compatibility, connect only one "3V" pin not two. A hypothetical future feather might place CAN RX/TX on the same pins but have 3V/Aref pins instead of two 3V pins
- Consider placing RX and TX labels on the silk next to the pins
- I would have preferred a solder jumper to enable the termination resistor
teal bear
thanks - I'll pass that up the pipe. (it's a very short pipe)
0.1" pitch jumper ... me too :p

Hi All - I'm curious if anyone has done any development to support the parallel capture controller I/O on the SAMD. I did a little bit of sleuthing around here first, but most of the references go back a year or two.

Anyone familiar with this interface? Or more specifically, how to take advantage of it from the SAMD?

@analog bridge That's my assumption. That PR just makes everything the actual size it should be. I know there is a point where FAT12 becomes FAT16 but I'm not sure what the boundary is. @tulip sleet would remember
@onyx hinge not sure. does ignore actually not declare the object or just omit it from the microcontroller pin table
tulip sleet
@analog bridge @slender iron 16MB is the normal transition from FAT12 to FAT16 (it actually depends on number of clusters, so it could be different the clusters are not 512 bytes, but they usually are)
slender iron
hrm, and the 16MB storage will use the first few MB for circuitpython code and not the FS
so the FS won't hit 16MB
supple gale
i believe its 2MB. 4086 clusters
MIN_FAT16 is 4086, anything below that is FAT12.
fmt = FS_FAT12;
if (nclst >= MIN_FAT16) fmt = FS_FAT16;
if (nclst >= MIN_FAT32) fmt = FS_FAT32;
ah! and I think the partition on the 4MB version is just under 2

seems to be 1MB on mine. (4MB flash). On the 16MB I get a 12MB CIRCUITPY drive. fwiw.

idle owl
@slender iron Have a minute for a question?
slender iron
yup!
idle owl
Excellent. In the meeting when Limor suggested including an example for the LED Animation library that resets the board on M0 if time.monotonic() is over 100k, you seemed like you were going to say something, and then didn't. Did you have another suggestion or some input on that?
slender iron
ha ha, ya. I was thinking ahead about whether we want to reset the internal clock on reset
idle owl
Ahh ok.
So not really related to the example then, it would be behind the scenes things?
slender iron
I think we'll want to remember the start up time and subtract it out from the internal clock
yup
idle owl
Fair enough. As long as I have you here, I don't know what code is needed to reset the board. Is it microcontroller.reset or something?
slender iron
yup, I think it's that exactly
slender iron
I could be wrong 🙂
idle owl
I'll find out!
slender iron
np
idle owl
It reset doing that from the REPL, so I suppose that's right 🙂
And the code works. Hurrah.
slender iron
🎉
idle owl
@slender iron She said 100k when she mentioned it, but I'm looking at a print of time.monotonic() and it only has 5 digits printed. So I would assume that the timing precision would be lost over 1000.0 or at the top end 10000... am I misunderstanding this?
slender iron
it's not as clear as a decimal value because it depends on bits
idle owl
hmm alright
idle owl
True that. I'll ping him. Thanks!
slender iron
np
idle owl
@tulip sleet See above. I'm looking to avoid the loss of timing precision for LED Animations. On the M0, right now, if you let it run long enough, they slow down because of loss of precision in time.monotonic(). I'm writing the code that resets the board before that happens, but wanted to know what to set it to. Limor said 100k, but that doesn't jive with the printout I'm getting in the serial console for monotonic().
The code works, but I need to know a good number to set if time.monotonic() > foo:
tulip sleet
@supple gale @slender iron @analog bridge This is the definitive FAT documentation (it's more than FAT32, despite the title). See in particular page 14: "Fat Type Determination": http://download.microsoft.com/download/0/8/4/084c452b-b772-4fe5-89bb-a0cbf082286a/fatgen103.doc
@idle owl I think I figured out the boundary for loss of precision in an issue. Let me look...
idle owl
@tulip sleet Thanks!
tulip sleet
@idle owl https://github.com/adafruit/circuitpython/issues/342#issuecomment-337228427. time.monotonic() starts to lose precision at 2**22, which is only about 1.165 hours. So I'd say reset (microcontroller.reset()) once you reach an hour (3600 seconds).
idle owl
@tulip sleet Perfect, thank you so much!
tulip sleet
an hour is easy to remember and understand
idle owl
Indeed it is
onyx hinge
At 1.165 hours it would start losing the ability to count each single millisecond, though probably the times LED animations deal with are probably bigger, like 10ms or 100ms aren't they?
idle owl
@tulip sleet I'm writing an FAQ for the LED Animation guide that explains the slow-down on M0, and includes this example. May I run it by you once I'm done to make sure I explain it right? I can't copy what you wrote it's WAY more detail than this needs. In fact, reading what you wrote, I may need your input before I write it.
tulip sleet
sure
onyx hinge
(not that resetting hourly is bad or would usually represent a problem)
tulip sleet
well, we could say about an hour per msec, but once an hour is an easy rule of thumb, and probably wouldn't disturb anyone
idle owl
Thanks. Ok, so basically, on the M0, time.monotonic() is only capable of a certain number of digits, so the precision of the float decreases over time. After a particular amount of time, it's no longer a float, meaning.... ok I'm lost here on how to explain this I think.
How would you explain this to a newbie? Someone running LED Animations on their CPX, and the comet slows down if they leave it running too long.
tulip sleet
it's still a float, but it loses accuracy
actually it's not an hour per msec, since the loss doubles about every hours
it would be like a clock that ticked only every 2 secs instead of every second after it ran for a while, then after another hour it would only tick every 4 seconds. So the loss in accuracy is the smallest interval we can measure. That interval goes above 1msec after about an hour.
idle owl
Ahhhhh
tulip sleet
i am wrong about doubling every hour, that's not true. The internal tick count is still accurate, but when it gets converted to a float we lose precision. That is, there is an internal tick count that's still accurate, but there's no way to pass that value to the Python code.
idle owl
Fair enough
tulip sleet
Another example (not a float), is suppose you could only represent a monetary value as, say 4, significant digits. You could represent $99.99 exactly, but once you get to $100 you have to start quoting the value in tens of cents, not exact cents. But that's probably too stretched of an analogy
idle owl
Hmm, not such a stretch maybe.
I liked the clock one but it doesn't cover the digits issue.
idle wharf
I saw this "convert a PR into a release note" github action and thought you might find it interesting with sooo many changes going on.
https://github.com/tiangolo/latest-changes
slender iron
@idle wharf My ideal would be that it modifies a draft release, not a committed file.
idle wharf
That one just popped up on twitter for some reason, but If I stumble into that one specifically... I'll let you know. 😉
idle owl
@tulip sleet Ok here's my attempt at explaining it: https://learn.adafruit.com/circuitpython-led-animations/faqs#on-the-samd21-why-does-my-animation-slow-down-if-i-leave-it-running-for-a-while-3074335-3 I have a PR in for the example I wrote to include in the FAQ, so the example is currently missing.
I explained time.monotonic() in my Hacking Ikea Lamps guide, so I linked to it instead of going into it much in the FAQ.
tulip sleet
@idle owl it's not that the clock is inaccurate, but that it ticks less often. So instead of seeing the second hand tick every second, jumping from one second to the next, it just jumps in two-second intervals, then four, etc. Also, I am confused: is this SAMD21 specific? I thought is was just on builds that don't have longints. I thought if the build supported monotonic_ns() (like, say, Metro M0), then you don't have this problem.
tulip sleet
it is true on non-express builds on M0 boards
trinket M0, Gemma M0, PyQT without external flash
tulip sleet
more specifically, any board that doesn't implement monotonic_ns()
but non-express is easy
idle owl
refresh it
tulip sleet
so it's not as if time slowed down, it's just that the clock is less accurate. For instance, if you were trying to see how long something took (like, say measuring your pulse), and the seconds jumped betwee 0,4,8, etc. you would get pretty frustrated.
idle owl
Ah alright
tulip sleet
"on a SAMD21..."
idle owl
good catch
teal bear
"slow down" isn't the right wrods. "jerky" or rough is better..
idle owl
@tulip sleet Alright refresh again.
tulip sleet
the second hand jumps two seconds at a time, then later four seconds, etx.
that's good! looks quite clear to me
idle owl
Excellent! Thank you so much for your help!
tulip sleet
yw!
idle owl
If anyone has a moment: https://github.com/adafruit/Adafruit_CircuitPython_LED_Animation/pull/68
It's for a QT Py guide (and the FAQ), but I figured it was good to have a few examples that run on M0 in the library so I put them there instead of the Learn repo. Also, easier to maintain.
tulip sleet
why don't you say "after about an hour has passed" instead of "a certain amount of time". That motivates the 3600 seconds.
tulip sleet
or after about 70 minutes (1.165 hours is 69:54, according to alexa)
tulip sleet
i just got an echo show and am using voice to compensate for bad elbow
idle owl
We have one of those. Have fun with her hearing you when you didn't mean for her to, and mishearing you when you need her to. 😄
tulip sleet
i was wrong that it only takes an hour to go from two to four seconds. It takes about one hour to go from one to two, then about two hours to go from two to four, etc.
idle owl
Also use headphones in meetings and during AAE. Phil cares not a bit about using her name.
tulip sleet
i have been disabling it at times 🙂
idle owl
@tulip sleet I updated the clock bit to say "after another two hours"
tulip sleet
ok, excellent: clear explanation for a confusing concept 👍
idle owl
Great! We did it! 😆
Can you take a look at my LED Animation PR? It's only added examples.

@idle owl I also looked at the PR (not really used to doing reviews yet!) I don't have the express or haxpress to actually try it but the examples all look good from all my time in this library before. Do I just put a comment in there to say such?

Hey @slender iron I'm sure you are aware that change turns on the async/await syntax for CircuitPython.
It's a fairly big addition - thanks for taking it. I hope this greatly expands CircuitPython applicability with the top tier hardware support y'all have created and now an available asynchronous programming paradigm that tries to be faithful to CPython.
I believe it's non-intrusive to users who want to use CircuitPython as they always have and I hope it's useful to others (besides me)!
slender iron
haha, that's the smallest big change I've seen 🙂
I appreciate your persistence with it. I'm happy to see us match CPython
low sentinel
Big implications for the questions you will get in this channel though 😬
slender iron
you are the person who added it 😉
hopefully matching CPython will lead to fewer gotchas and questions
low sentinel
Yeah, I'd like to consider any functional difference as a bug. It should work the same way. There is a lot of surface area though and people are creative. Should be good fun though. Feel free to @ me :-p
slender iron
😄 thanks!
I don't plan on teaching people how to use it so they'll be on their own. I'd be happy to promote any tutorials or libraries you create though.
low sentinel
Sweet! I'll make a context manager for busio when I get a chance. A tutorial would be a good thing to do as well yes.

hey all, lmk if you have any thoughts about what a pleasant way of setting entries in a look up table in python should work. Size is limited to 8 entries and map a temperature to a fan speed. Current default plan is to make it work similar to a dictionary but 🤷
slender iron
should the temp entries be sorted?
grim dagger
@slender iron I just tried to build and test CP with your STM RTC fix in it. I wanted to try SH1107 I2C, but the build seems to not include the SH1107 quirk? I'm probably missing something obvious but I'm getting the "extra keyword arguments" error from my SH1107 driver with this build.
slender iron
@grim dagger are you on my branch?
I think it's based on the latest so it should have it
pastel panther
@slender iron yes they should be sorted
grim dagger
I'm on master. Wasn't sure about master or main. I have sync'd to the latest adafruit stuff and sync'd submodules. Your fix is already merged so I thought this would work.
slender iron
main
grim dagger
Argh
pastel panther
or at least that's how they'd be used. There are 8 lut slots and the sensor expects each to be greater than the last
slender iron
@pastel panther are the temps fixed? if not I think a dict with a size limit makes sense
pastel panther
@slender iron The number of lut entries is fixed, is that what you mean?
I agree that it's not dictionary-ish
slender iron
I was wondering if the temp thresholds are fixed
grim dagger
Can't seem to build main:

@grim dagger make sure all of your submodules are up to date (I suspect protomatter isn't)
pastel panther
no, the temp thresholds in the lut are not fixed, you can update them
onyx hinge
I'll be in the voice channel if anyone wants to do a mic check. See you in about 14 minutes for the meeting.
slender iron
kk, I think a dictionary-like object with a limit of 8 entries is fine
you can handle the ordering internally
pastel panther
ya
grim dagger
@grim dagger make sure all of your submodules are up to date (I suspect protomatter isn't)
@slender iron is "git submodule sync" not enough?
slender iron
sync only sync the url source
you also want git submodule update
git status should show a change
before you update
pastel panther
I'm thinking I'll raise an IndexError if they try to set a 9th and instruct them to update or remove an existing entry
onyx hinge
@lone axle are you able to paste links today, especially during the news section?

yes git status was trying to tell me. sorry... have never worked with a project that has submodules before!

hmm. so I successfully loaded the bin to my board but it doesn't show up on my computer. hmmm
slender iron
if you have serial but not the drive, that means the flash config is incorrect or it's mis-soldered
ornate breach
Checked the board and pin assignments and soldering
ornate breach
@slender iron should it initialize properly from the bin generated by run the make BOARD=CP_Sapling_m0 ?
Or do I need a different bin?
slender iron
do you have a bootloader installed?
I think by default the bin will be positioned for a bootloader
ornate breach
No, I was using the DAP to program the bin I built
The printout on the serial monitor indicates it successfully programs
Would that bin not work for boot loading or do I need to do something different?
ornate breach
Hmm okay
orchid basinBOT
ornate breach
@stuck elbow is the bootloader the same for every samd21e18a chip?
stuck elbow
no, it uses LEDs that may be on different pins
you can use the one for fluff m0, it has all leds disabled
ornate breach
where do I find the bin for your fluff?
stuck elbow
weird, there is no link on the downloads page, I thought it was added
ornate breach
nvm, I'm going to make one off the uf2 repo
ornate breach
cloned to local and adding config stuff
stuck elbow
ah, there was no release yet since fluff was added
slender iron
@ornate breach you can also build circuitpython to not be offset and run on its own
ornate breach
okay... so after the bootloader is on and it shows up serial and as bootdrive
I just drag the CP uf2 to the boot drive for the board
ornate breach
alright... it came back up as Circuitpython drive
that's really exciting
now... I need to flash the neopixel
thorny jay
I wonder how you develop for the Matrix Portal M4... or let's say how you power the Matrix Portal M4 and communitate with it? Windows 10 on my laptop complained that this USB device was pumping too much power (it was in French, but I have a picture). And that of course because I was with a lot of white pixel. Do you use a splitter to have power from an external source but USB data to your computer? Do you power the matrix externaly and not from the Matrix Portal M4? Do you reduce the brightness while developping and change that depending if USB is connected? What is your trick (and is it documented in the learn guide)? ( Maybe for @gilded cradle )
gilded cradle
@thorny jay I was able to plug it into the USB-C port on my Macbook Pro (which should deliver up to 3A). If you are using a USB3 port, I think 900mA is max, so you may need to use a powered USB hub. I'll have to give it a try whether that works to know for certain.
thorny jay
Sorry, using an old second had T440p... one USB might be "high power", I need to give it a try.
ornate breach
hey @slender iron should the neopixel be on when the CP uf2 is loaded?
thorny jay
Also, powering a 64x64, it might not help to have the dubble of pixel.
gilded cradle
You can always connect the matrix power to one of these and external power: https://www.adafruit.com/product/368
slender iron
@ornate breach if you have it setup
thorny jay
I was thinking that maybe this kind of thing was the trick: https://www.8086.net/product/usb-pwr-splitter
gilded cradle
Yeah, something like that would probably work too.
thorny jay
Thanks, that will be for tomorrow or my long week-end. But the auto-orientation of the Matrix Portal is impressive... even work for the Blinka Logo that is always on the top left, whatever the orientation it seems (at least the boot time orientation).
gilded cradle
Nice, I hadn't tried that out.
slender iron
@thorny jay a powered usb hub may work too

hey @slender iron I can see the repl in the arduino serial monitor but it won't pull up in MU

stuck elbow
shame they didn't connect the main mcu to usb
simple pulsar
What difference does that make? Is more efficient?
stuck elbow
it would allow porting circuitpython to it, because then you can make the CIRCUITPY disk visible to the computer
as it is, you always have to "compile" whatever you want to put on it into a hex file
which really sucks
also, you can't make it act as a keyboard or mouse
or a midi device
simple pulsar
Interesting. I thought I saw a discussion about USB HIDs for microbit.

it would have to be implemented and flashed to the "helper" chip that programs it

Hello all, new here wondering if anything precludes using circuitPython on Arduino MKRWifi 1010 and MKRGSM1400. I could find MKRZero and MKRWan circuitPython available for them
stuck elbow
they are both samd21 so should work
wifi and such will not
unless you write a custom library to use them
peak cedar
I need Wifi + Bluetooth for a new project and got a few MKR1010 lying around here, oh well I guess this is way over my knowledge grade here, thanks

@slender iron re discord bot community bundle: do you know if it's possible to have the actions that run on the PR check for this and fail at that stage as well. That way we could try to catch and fix before it's merged. I can try to look into that, but have little experience with actions. I am unsure of the bounds of what all it can do (or if there is some reason we wouldn't want it to do something like this).
slender iron
@lone axle I was surprised that it wasn't run already. It should be doable
lone axle
Does the community bundle pull in changes automatically? So if this user fixes it in their repo then it will automatically be fixed in the community bundle? Or do they need to fix it in theirs and make a new PR to pull in the changes?
slender iron
the bundles pull the latest release automatically
peak cedar
@slender iron do you confirm the infos I was given re arduino MKRWifi1010 & MKRGSM1400 : board should work but no luck with Wifi/Bluetooth or GSM ?
slender iron
yup, the wifi and ble are separate chips that we don't support
the BLE might be workable with the new ble_hci stuff but we haven't tested it
peak cedar
too bad, thanks anyway
slender iron
let arduino know you want it 😉
peak cedar
will do 🙂

@digital ibex Is there a difference in discord.py and adafruit_discord.py in your library? at first glance I didn't notice anything, it looks like maybe one is a newer version?

digital ibex
@lone axle I was intending to make a version that runs on PC. discordbot.py is that version and it is a work in progress.
lone axle
@digital ibex ah. It turns out the community bundle needs either a single py file or a directory with multiple inside.
digital ibex
Oops! I will fix that.
lone axle
Can you move those py files into a dir and maybe rename the one to pc_discord.py
lone axle
Yep, thank you.
I didnt know that until today either. Im going to look into adding an actions check for it
digital ibex
@lone axle I fixed it! I'm tagging the code right now. I think the PC version will make its home in a new repo.
slender iron
any ideas on how we can free up some space on the metro m0?
there is 2k free with gcc 10...
blissful pollen
@tulip sleet should I roll back the changes that were board specific?
tulip sleet
@blissful pollen yes, since really there are no SAMD21 boards that need OrderedDIct. The ones that fit are accidental, because we removed other things, or because they don't have many pins. The Feather and Metro M0 are the standard SAMD21 boards, so if they don't work for those, no reason to add to the others.

Was wondering if Adafruit Cpython could be run on an stm32h7.. I really do need all that power and really do want to use Cpython... I know I can load Cpython but I'm not sure about the Adafruit version.
Wait wrong channel.. I'm new

@indigo wedge did you make any progress last night with the airlift firmware? If you set debug=True in the initial call in the airlift library, does it print out anything from the ESP32? I can try to duplicate your setup (minus your special board) to confirm what is and isn't working
indigo wedge
no, didn't get any further, yes I get boot prints if I enable debug, it fails at the step where it passes the uart and gpios to _bleio.Adapter, I get a HCI write error, i tried doing busy=rts, gpio0=cts and busy=cts, gpio=rts
the wifi part of the firmware works
tulip sleet
@slender iron I am going to make a PR to add HCI _bleio to all boards for which it will fit (plain Metro M4, etc.). Right now it's only enabled for the MM4 Airlift Lite board. Would like to get this into the rc
hazy plover
Is there a table of the size of the CP drive for each board?
It looks like it is the size of the SPI chip except on the Trinket M0 it seems to be about 48k.
Specifically, my guess is the QT Py would only have 48k for CP without the optional SPI on the back.
tulip sleet
@hazy plover it's in the product descriptions in the store. Non-express SAMD21 (M0) boards are 64kB (minus overhead). Express boards are generally 2MB, but a few are 8MB (PyPortal, I think). There are some special cases like certain non-product nRF52 boards where part of the large internal flash is used.
"Express" means it has an external flash chip
slender iron
@tulip sleet ya, we can get that in for rc
hazy plover
@tulip sleet If it's there, I missed it and I've spent quite a while working on it.
The Store says the PyPortal has an 8MB chip and Windows says it has an 8MB CP drive.
The Store says the M4 Express has an 2MB chip and Windows says it has an 2MB CP drive.
The Store says the Trinket M0 has an optional chip and Windows says it has an 48k CP drive.
So, again, my question is should one expect that, at a minimum, the CP drive will have approximately the size of the external flash chip. I don't have one of everything to test but that's my conclusion from the 3 different boards I have.
tulip sleet
that is correct. But the Trinket does not have an optional chip (the Py QT does). You need a separate build of CPy to access the optional chip. I'll check the Trinket product description
the major major motivation for the external chip is to use it for CIRCUITPY
hazy plover
@tulip sleet
That brings up another question. Why can't CP identify the size of the flash drive without a separate build?
tulip sleet
the smaller build has other missing features, so you want the larger build. The SAMD21 has 256kB flash. When there's no external flash, there's only 192kB for CPy and 64kB for CIRCUITPY. When there's an external chip we can use the whole 256kB for CPy, and enable a bunch more features (like longints0
hazy plover
The larger build will recognize the 2M chip on the QT Py. Will it also automatically recognize the 4M from the same family?
I think that is the largest that will fit the narrow package.
tulip sleet
Each build specifies the chips it tries to recognize. We don't include data for all possible chips because it would take too much space. It's the EXTERNAL_FLASH_DEVICES line in files like this: https://github.com/adafruit/circuitpython/blob/f1e8f2b404ef45edf08b019c1e68d595aa69b357/ports/atmel-samd/boards/qtpy_m0_haxpress/mpconfigboard.mk#L13
you can add another flash device to that value and make it a comma separated list. Then you also need to change EXTERNAL_FLASH_DEVICE_COUNT to 2 or whatever.
you can find examples in other mpconfigboard.mk files
hazy plover
In reading through several .mk files, they all seem to be only set up for one specific size like 2X16. If different size were specified in the list, would the actual chip be recognized as the correct size or does it only work with one size?
tulip sleet
@hazy plover it works with whichever chips are in the list of EXTERNAL_FLASH_DEVICES. The devices have ID information that is checked to determine which chip it is (including its size).
it tries all the chips in the list
hazy plover
@tulip sleet Great. Thank you.
On a different question, I have a PyPortal reading a I2C UV sensor (GUVB-C31SM) which seems to work fine once it gets started. However, sometimes it soft reboots several times.
What are the most common reasons for reboot on start-up?
tulip sleet
is it connected to a host via USB? If the host is writing to CIRCUITPY (it could just be the metadata for the filesystem), then the board will restart on each write. If you have any utility software on the host computer, such as an indexer or anti-virus, backup program, or disk utility, those programs can generate writes to CIRCUITPY.
hazy plover
Yes. Connected to Win10 via USB. I'll try an external supply.
tulip sleet
vanilla win10 wil not do this: it's usually due to some third-party piece of software
@indigo wedge were you testing on an i.mx board? how did you get around the problem of needing ByteArray.h, but CIRCUITPY_NVM = 0, which disables that?
hazy plover
@tulip sleet After half a dozen power cycles using an external supply, no soft reboots. So it's probably anti-virus.
Thanks again.
tulip sleet
you might see if you can prevent your antivirus from scanning that particular drive. which one is it? I like to keep track of this kind of thing
hazy plover
Bitdefender.
tulip sleet
I'll make a note, thanks! and glad it works otherwise
hazy plover
I'm getting fairly valid results comparing to a Newport 818-RAD which is a cosine corrected detector. I still need to assemble a goniometer to measure intensity versus angle for both detectors and then test my constant current source that is controlled by CP to step the UVC LED intensity across a broad range to insure my detector is linear.
Circuit Python has made this fairly easy.
indigo wedge
@tulip sleet I just implemented ByteArray.c on imx, but haven't really tested it yet
tulip sleet
_bleio just uses it for bonding info, which isn't even implemented in the HCI version yet
I could try to conditionally compile the bonding stuff so that if CIRCUITPY_NVM is 0, it doesn't try to include ByteArray.h. I may do this to get the other builds working that are now failing due to this (including Spresense and i.mx)
indigo wedge
that probably makes more sense 🙂

@tulip sleet or @onyx hinge could you turn off the VM opt for the metro m0 FR build? it's causing us size issues
it's a bit hard for me to test because I'm using gcc10
tulip sleet
I can include it in the PR I'm making for _bleio hci

k, please reply dan

@slender iron the actual problem is interesting ... There a space that was entered as unicode U+202f 8239 NARROW NO-BREAK SPACE “ ” instead of just "space". This causes memory usage to increase, because some tables have to be 16 bits instead of 8 bits.
tulip sleet
maybe the python script should check for odd spaces like that
slender iron
so how much space do we get by fixing that?
manic glacierBOT
slender iron
and will we actually mess something up if a break does occur there?
onyx hinge
From what I understood, French puts space before and after punctuation which we put space after in English. so the translated string said "Output_: ", trying to prevent a line break before the ":"

the non-breaking space is included when the punctuation mark is two parts, like semicolon or question mark (but not say period or comma)
