@worn birch did you do git submodule update --init --recursive, or did you pull after several weeks of not pulling? The adafruit_usb_descriptor directory became a submodule a few weeks ago.
#circuitpython-dev
tulip sleet
idle owl
Oh good to know.
pastel panther
Hey @tulip sleet, the SAMD51 datasheet doesn't list a SWDIO pin in the pinmux section but mentions it as PA31 on page 35. Should I take that to mean it's whatever PA31 is on the given device?
idle owl
I've had to do the submodule update each time even right after I do a pull.
idle owl
@worn birch Excellent!
errant grail
I have a beginner's question about converting helper methods into a library. The complication is that the methods need to act on board pins that are defined in the main program. Is there a way to pass the pin defs into the methods or do I need to move the includes and define the pins in the library package?
idle owl
@CGrover#2710 The one I've written has the includes and definitions like that in the library package. But I don't know that it has to be done that way.
fast hazel
@errant grail , so you'd like motor_speed to be in a library, but be able to act on something like ain01? You can just pass it as a parameter to motor_speed and you should not need the imports in the library. As @idle owl pointed out, it doesn't hurt. But it shouldn't be needed either as long as you're just accesing properties / methods of the thing passed in (e.g., ain01.duty_cycle, etc.).
errant grail
@idle owl @fast hazel Thanks! Yes, I'd prefer to leave the board pin defs if possible, but I'm not sure that there's an advantage to doing that in the long run. You've given me something to think about. Also, I'll need to better understand how an object's properties are passed back and forth with the library methods. Back to the books! 😃
worn birch
ok any idea how to tell which port the board is attached to on linux? bossac can't find it
is there something similar to deveice manager on windows
idle owl
Yeah, but it's more checking the directory I think. But I don't know know the specifics.
I'm on MacOS.
I'm trying to find it though. Oh, wait, hold on, I might have something that will tell you
/dev/ttyACM* maybe?
The * being a number I think
hollow tartan
Wow, My Metro Express was flashing these crazy colors at me and I do not know what to do.
It was Green, then Purple, a yellow and two cyan flashes.
I had loaded a main.py that to wanted to run & test. Really stuck in this problem.
idle owl
@hollow tartan It does that when there's an error in main.py. The yellow and cyan are related to the line number. Did you try connecting to the REPL? It should throw an error as well.
idle owl
Yes, it should be fine. But you'll want to figure out what the problem in main.py is. The REPL will give you a line number typically and at least a hint at what's going on.
hollow tartan
So the flashing colors tell what the error is ; how interesting and efficient that is.
idle owl
Yellow and 2 cyans will mean line 2 or line 12, I'd have to see how it's flashing to be sure, but yellow usually counts 10's and cyan counts 1's.
worn birch
Success!
idle owl
@worn birch Yay!

Thanks @idle owl I found the page of colour codes to help me understand.
idle owl
@hollow tartan I was looking for it, glad you found it. Can you link it for me? If I bookmarked it, I must not have categorised it.
hollow tartan
Sure, just a sec.
The Blinking Error Codes are explained near the end of https://learn.adafruit.com/adafruit-metro-m0-express-designed-for-circuitpython/downloads?view=all#m0-boards-faq

Oh right. Thank you!

@idle owl I was testing and entered servo = Servo(board.D9)into REPL. Then tried to load the program and it blows up because the pin is already assigned and in use.
Is there a keyboard entry to reset just before a load and run?
idle owl
Using ctrl+d and then reenter the REPL will work, but I'm not sure if there's a keyboard entry to reload it otherwise.
hollow tartan
I will give it a try. thanks.

tulip sleet
@pastel panther yes, looks like PA30 and PA31 on any package, and you just to have look up the actual pin number. The SWDIO missing from the PA31 line on the SAMD51 datasheet looks to be a typo. It's on the '21 datasheet

use the bundle pieces all together because there were some naming changes and the bundle is consistent

I ran into that twice today.
idle owl
Ah I wasn't sure what it was pulling from. I'll look at the .py file
hollow tartan
C:\AdaFruit_Archive\Metro Experimenter Guide\METROX-Examples-and-Project-Sketches-master\circuitpython\CIRC04 in this folder is servo.py
idle owl
I don't see set_angle in simpleio
hollow tartan
neither do I
idle owl
I see pwm.angle under Servo though
Did you scratch write the code or did you grab it from something?
idle owl
Yeah I see it. The example in simpleio looks just a touch different.
import simpleio
import time
from board import *
pwm = simpleio.Servo(D9)
while True:
pwm.angle = 0
print("Angle: ", pwm.angle)
time.sleep(2)
pwm.angle = pwm.microseconds_to_angle(2500)
print("Angle: ", pwm.angle)
time.sleep(2)```spacing is off because it's out of the driver
hollow tartan
is that meant to drive a servo?
idle owl
Yeah, as far as I can tell, it's meant to alter the angle of the servo.
It seems like a really simple example, with not much use of what I assume is probably a much more involved driver, but it would at least get you started if it works.
The example is specifically for the Metro M0 Express.
import simpleio
import time
import board
pwm = simpleio.Servo(board.D9)
while True:
pwm.angle = 0
print("Angle: ", pwm.angle)
time.sleep(2)
pwm.angle = pwm.microseconds_to_angle(2500)
print("Angle: ", pwm.angle)
time.sleep(2)```Correct spacing and import board instead of from import *. More efficient.
hollow tartan
good enough. thanks.
code seems to be running now, but the above has an error. servo = simpleio.Servo(board.D9) I did not utilize pwm.microseconds_to_angle(2500). Full disclosure.
idle owl
Oh right, because I changed it to import board, sorry about that. Good catch.
Glad you got it working!
I'm headed out. Good night!

some how lost storage ...
import storage```
doesn't work ... ratshow is that possible?
slender iron
@worn birch it might be off in master
pastel panther
For when OSHpark would take too long and you're impatient to try the new toys: Hot glue and dead bugs
slender iron
@pastel panther SWDIO is automuxed when a SWCLK signal is received on PA30. it confused me too
now back to gaming
worn birch
@slender iron right ... what exactly does that mean ... is there an easy way to turn on?
pastel panther
It's probably off because it hasn't been updated to work with 3.0. It should be available in 2.x
worn birch
Ah, I see ... so I gather I can cherrypick commits from the master then and test them out in 2.x ... obviously within my own fork
pastel panther
Theoretically yes though if you're talking about SAMD port specific stuff it likely won't work as they changed from using ASF3 to ASF4
worn birch
right ... not sure what that means
pastel panther
Unless you're talking about playing with SAMD51 stuff, you're likely better off just using 2.x. 3.0/master isn't even to beta yet
worn birch
while in the topic does the README.rst within ports/atmet-smad get auto generated or idoes this need manual update
worn birch
well ... i just updated the pins for adalogger and the pull request got accepted ... but if I made the change I should have updated the docs
so if its not auto generated I'll have to go and do it ... I am leaning towards its not

stuck elbow
Some progress. A simple platformer game is now possible.
slender iron
looks awesome @stuck elbow
stuck elbow
I also have a guide on how to build this with a feather m0 and a 128x128 display module
so that you don't need to have uGame
pastel panther
@stuck elbow That's awesome!
@stuck elbow I'm working on a m4 board if you're interested in using it to make a m4 version
I got it talking to gdb and jlink commander last night
stuck elbow
nice
I will definitely explore the m4 option once it's all a bit more stable
I need to test SPI and I2C on the metro for now
that platformer barely fits in ram, btw. — larger games will definitely need to be compiled into .mpy
pastel panther
it looks like you're using the same screen as me as well
stuck elbow
ST7735R 128x128
pastel panther
Ya
stuck elbow
I think it's the cheapest RGB LCD you can get
pastel panther
Actually I just checked and I have the 128x160 version of the same
stuck elbow
the 1.8" one?
pastel panther
ya, got it from adafruit
pastel panther
Did you essentially make a custom CP board?
stuck elbow
yes, trinket m0 with flash
pastel panther
is that the trinket_m0_haxpress in the boards directory?
stuck elbow
close, but I also added more pins
I didn't make a pull request with that board, because it's not final yet
things may change
stuck elbow
Fritzing 😃
https://github.com/pewpew-game/circuitpython/tree/ugame/atmel-samd/boards/ugame <-- here is my board definition
pastel panther
Cool
The board I'm working on is essentially a trinket pro m4 express. Or maybe a itsybitsy m4
stuck elbow
nice, I will probably steal from your design for the m4 version of ugame 😃
pastel panther
It's pretty convenient because the samd51G has nearly the same footprint as the 21G that is used on most of the adafruit boards
open source hardware for the win!
pastel panther
I'm going to include the watch crystal but you can always remove it and clean up a few mm^2
I'm just including it because it's on the metro m4 and I'm trying to stay close to that, but I don't think CP uses it
stuck elbow
well, I will make a custom pcb anyways, with the display and buttons and all that
stuck elbow
it fits my workflow much better
I can switch between the pcb and the schematic views, and the changes made in one appear in the other
I can also start with a pcb without a schematic, and add the schematic later
which is nice when doing things like, say, they buttons — I can route them to the nearest pins
without having to decide up front which is which
I also hate kicad's and eagle's 1970s user interface
and the parts library is horrible
pastel panther
I hated eagle's interface when I started but now I have stockholm syndrome so it's all good
stuck elbow
yeah, it's all a matter of what you are used to
pastel panther
KiCad is actually functionally much better but I'm still learning it's quirks. The UI is horrble though
It's got the classic "designed by engineers" look
pastel panther
That would be nice
stuck elbow
I learned to work around most of the bugs by now, but still
and it's buggy in worrying ways, like what gets highlighted on mouse-over doesn't match what actually gets selected — which suggests there are two different code paths for the two, which is just wrong
pastel panther
That would drive me crazy.
stuck elbow
if only there was a project like Fritzing, but written in Python
bonus points for being compatible with Fritzing's file formats
pastel panther
Good luck with that
stuck elbow
nah, I'm too old for such a project
pastel panther
Plus the last thing we need is another fork
pastel panther
Fair enough
stuck elbow
a fork that tries to take over the existing community would be bad, a fork that builds its own community is actually very good
pastel panther
Sure, forks that serve new markets are great, but I think (based on nothing) that they're the minority
stuck elbow
the majority of forks are personal experiments
pastel panther
Sure, but I don't think that's the type of fork we're talking about. I mean forks that indend to 'fix' an issue with the original project
stuck elbow
the "hostile" forks are signs of bad thinks happening in the community, but I think they are just symptoms, not the cause
pastel panther
I agree
stuck elbow
and they sooner or later either take over and kill the original project, or die off themselves
so in the end all is good
pastel panther
I guess. I just look at it and can't help see 'wasted' effort. Perhaps that depends on your definition of waste. Presumably any good ideas would live on?
stuck elbow
can't wait for Mozilla to get merged back into Mosaic 😉
pastel panther
ha
stuck elbow
it's not wasted, it explores possibilities
sure, it's messy, because humans are messy
and emotional
I guess the worst case is when the projects are not really free and open, and the argument is a power struggle — like it was with Arduino just recently
worn birch
@slender iron Aha ... a single line of code ... always the case. ... thanks for that ... good to know for the future ... any adalogger specific items you need work done on ?
I'll check out the issues page and see if anything jumps out at me

You're now a Circuit Python Helper!
If you look on the right side of Discord, it's in the member list
worn birch
Ah right ... I'll do what I can ... still pretty fresh though
idle owl
Part of the role is that you'll be more easily notified when we're up to something. You're not on the hook for anything 😉
slender iron
😃
worn birch
The setup you have going with Discord, Github, Travis and Rosie is a little insane but very cool ... this is my first experience on a continuous integration project ... lets say open source project ...
idle owl
@worn birch That's awesome! This whole thing is my first experience with it too.
I've been involved with open source for a long time, but not at this level.
worn birch
I recon I was about a few hours off having a Adalogger only rosie happening ... lol
idle owl
You got that far, you're not nearly as fresh as you think. Most of us aren't running Travis locally
slender iron
@worn birch I'd be happy ot help you get another rosie going
I don't run travis locally either
worn birch
Yea ... I'm not running locally ... using their system with a free account ... no way I have the computing capacity to do it locally .... unless you mean running it locally off your own forks
idle owl
That's what I was referring to. I don't have a Travis account setup at all.
I had enough trouble getting Sphinx setup... 😄
worn birch
@slender iron ok ... lets do it ... I got up the the point of working out what webhooks were in Github so I could configure the .env
slender iron
what computer are you trying to run it on?
worn birch
Ubuntu x64 VM
slender iron
on your windows box?
slender iron
kk
so there doesn't need to be any webhooks from github to rosie
its all travis to rosie now
worn birch
rightio ... so no need for that secret ... just delete it ... does it need a webhook secret from travis instead then?
slender iron
I don't think so. there is a different way it validates
worn birch
ok so i'll just leave that and move on to the rosie configuration of the readme then
what is a mike instance regard github logs?
slender iron
mike was rosie's old name
worn birch
true ... in the logs of course
... i need a tute on using nano ... gosh ... benn too long lol
slender iron
😃
idle owl
It does not. Only the Express boards do
worn birch
yea ... rosie only supports utf at least that is what he yaml config is telling me
I am assuming that has to do with memory available
slender iron
rosie doesn't know how to load code with bossac
idle owl
@worn birch What caused you to join us? Is the Adalogger your first Adafruit board or have you been doing other things for ages?
worn birch
the issue seems to be getting the board into the bootloader ... not sure if the non-utf boards have an interrupt
idle owl
I haven't flashed a non-uf2 board yet, which is totally on me because I have a few. Unfortunately the only help I'd be with that is linking you to instructions on Adafruit Learn and I'm certain you're way past that.
worn birch
@idle owl elec eng uni assignment ... and mech eng project ... two birds ... mech eng needed a gps logger ... elec eng subject required I work on a project ... hence first intro to adafruit ... haven't touched this stuff since my under grad days ... lol

@pastel panther thank you for the suggestion, have a segger j-link and will be using it for firmware development when I get there. iv'e also hacked the atmel edbg off an arduino zero allowing bootloader burning with just the arduino ide(really fun but nerve racking). do you know how/ if there is an alternate program to atmel sutiods for uploading bin files? or it the requied for atmel chips? thanks so much for your help/ sorry for the delay in responce.
idle owl
@marble hornet Other than the j-link? That has things that load bin files.
pastel panther
jlink commander can do it and I think gdb as well
I'm still fairly new to it though. @idle owl has more experience loading bins with the jlink than I do
@idle owl Do you use jlink commander or something else?
idle owl
I use JLinkExe. Is that the commander executable? Or is commander something else
marble hornet
thanks siddacious, i'll take a look!
pastel panther
@idle owl Ya, thats commander

any word from MicroChip about getting the PICkit 3 programmer firmware enabled for ATSAMD21 /ATSAMD51 ?
@idle owl I had a weird error report from CP. Way down on line 76 was the start of the Main Loop Forever and the indent got messed up with an extra space. It reported Line 1 as the error location.
idle owl
@hollow tartan It doesn't always get it right. Sometimes it reports an error in main.py when the issue is with a module. I believe it reports where it fails, which isn't always the same place as the problem.
hollow tartan
hmmm, okay, the 74HC595 shift register project worked out very well except for that minor issue. Is there someone working on the Metro Experimenter Guide\METROX-Examples-and-Project-Sketches-master\circuitpython\CIRCxx programs and Learn document. the arduino side is finished. I do know that those project examples are from oomlout.com BTW. They were available years ago when the Arduino Uno first came out.
idle owl
I don't know.
hollow tartan
simpleio.tone(board.D9,222,100)
works from REPL and should work in .py also. correct?
idle owl
I've run into times when it doesn't work in .py even though it worked in the REPL. It ended up being some syntax or somesuch. Theoretically if it works in the REPL, yes, it should work in a .py file, but in practice it doesn't always come out that way.
idle owl
In the grand scheme of things, I'm pretty new to Python. I usually assume it's something I'm doing wrong that's making it fail. I don't remember the exact details of the last time I ran into a file failing but the code working in the REPL, but the fix was something really minor, and I'm fairly sure I stumbled into it. I don't know enough about the code you're writing to be able to look at it and pick up what's going on. Everyone will be back tomorrow, and I know a lot of them are able to pick that stuff out pretty quickly.
hollow tartan
@idle owl do you see anything wrong here tones = {'c': 261.625, 'd': 293.665, 'e': 329.63, 'f': 349.23, 'g': 391.995, 'a': 440, 'b': 493.885, 'C': 523.25} simpleio.tone(board.D9, tones[note], (beat*tempodelay)) I am thinking the curly braces are not right
idle owl
Hmm, no the curly brackets are correct, I think it might be something else, hold on, I have an example like this I think.
hollow tartan
tones['c'] will hopefully pull out the number 261.625
idle owl
No the rest looks right too. Is it possible it's not happy with c and C as different names?
This was meant to work with the touchpads: python tones = { 'A1' : 262, 'A2' : 294, 'A3' : 330, 'A4' : 349, 'A5' : 392, 'A6' : 440, 'A7' : 494, }
The extra space around the colon shouldn't matter, but maybe try that too.
It seems like it might be something in the syntax of simpleio.tone
Where is note in your code?
idle owl
Hmm. I'm not sure. Your dictionary looks correct though. Can you post the entire file? I can try to make sense of it, but I'm definitely having trouble trying to put it together from pieces.
No guarantees either way though.

Can anyone explain to me why there's a DigitalInOut class and not a DigitalIn and DigitalOut class instead (or all three?). If ease of use is a high-want, I don't get that choice at all.
idle owl
Does that last line you posted separately need parens?
jovial steppe
IIRC, that's what they did in mbed.
idle owl
@jovial steppe Is it the carryover from MicroPython? That is a complete guess. The folks who could answer that will be back tomorrow, but I don't know if they'll be around tonight.
jovial steppe
I can only see it if use cases anticipate that one is going to switch back-and-forth between output and input all the time, but that's almost a rarety.
I don't know anything (yet) about MP, but the class is in the CP docs and clearly in the examples. I'll have look in the forums to see if it's discussed there.
idle owl
If you don't find what you're looking for there, I would suggest checking in during the week. Even on weekends sometimes, but with the holiday, everyone's been off.
jovial steppe
I suppose I2C would want the former because it's bi-directional. I just seems to be a stick-in-the-eye to usability for beginners. I'll try to catch @slender iron when he gets back if I don't see it mentioned anywhere. Thanks @idle owl .
idle owl
@jovial steppe Yep! Dan Halbert can also probably explain. Good luck!
jovial steppe
Maybe I'll toss it out in the forums. I don't see anything there already (a mention of DigitalOut comes up pretty much null). tkx
slender iron
@jovial steppe DigitalInOut isn't meant for beginners. The Python/C level API is meant to be the minimum needed to do things so simpler things can be built on top. simpleio has DigitalIn and DigitalOut to make things simpler in this case.
tidal kiln
@hollow tartan tempo is in bpm = beats per minute = beats / minute
to get the time per beat, invert it -> 1 / tempo = minutes per beat
to convert to seconds, multiply by 60 -> 60 / tempo
hollow tartan
AGREED. 😃 ( Ah well, this was just a place holder, until I could get back with the results of my investigation, you know 'facts'. ) RE: simplio.tone tones = {'c': 261, #tone needs an integer for the second arg 'd': 294, # which is the freq of the note 'e': 330, # to be played (approx.) 'f': 349, 'g': 392, 'a': 440, 'b': 494, 'C': 523}
jovial steppe
@cosmic fractal Thanks that helps. I just found the API documentation after stumbling around through the getting started guide for the MM0E. It wasn't easy to find. I don't see any reference to "simpleio" in the core modules docs (not that I've finished going through all of them yet, which I should have). I gotta admit I'm having trouble finding an easy path to getting stated. Maybe I'll look up the Playground documention that someone else mentioned above earlier today to see if that's a starting point, even though I'm using the MM0E. I wouldn't even know how to use "board" if it weren't for the random example in the MM0E product intro because there's no documentation for it, other than a placeholder.
(sigh)

I got started with some of Tony D's tutorials on SPI and I2C. There are a good amount of guides on the learning system
jovial steppe
I've got a test sketch for an educational shield that I make that I'm converting over from ArduinoC/Uno to CP/MM0E. The test sketch is split up into 20-30 tabs, so it's already pretty object-y. It uses a dozen-plus component types, more than the CircuitPlayground built-in. My Python is a few years rusty, and I don't have any experience with MicroPython yet, let alone CP. I'm just having difficulty getting the lay of the land. Ideally (for me) there'd be 50 pages of API documentation that I could read top-to-bottom to see the whole world. I'll concede that I'm a hater of "cookbooks", which seem to be what (too) many people consider documentation nowadays. I don't think that serves people who want/need the full-on view of the world, but I'm old-timey like that.
Python is just another language, that's not the problem. I've always liked Python, just never had the opportunity to do much serious with it.
idle owl
I see. ReadTheDocs has a lot of information, but it's not going to have everything you're looking for. It usually includes a basic explanation of a module, some details about the available parameters for each module, and some basic examples using the module. But I don't think it'll satisfy your worldview need. Beyond that, there's the Learn Guides, but there's not a central aggregated single guide that includes the detailed CircuitPython guides. As Sid said, TonyD has written up a number of fairly detailed tutorials for a number of the modules, but again, I don't know that he's covered everything yet.
The nice thing about Tony's guides is that he's coming from a solid Arduino background and often has information or guides on both, and some that even include both. I don't know if a comparison would help you better understand it or hinder your further learning.
pastel panther
To be honest, because CP is so geared towards beginners things like a robust, detailed and extensive API documentation aren't prioritized as beginners tend to rely on guides/recipes.
jovial steppe
I've already found three of Tony's videos about MP, but I don't think I've seen/found anything of his on CP. I think that I get the intent of CP over bare-MP. I guess I just wrongly assumed that the docs were more fleshed-out than they were at v2.1.
My plan was to use the MM0E for an intro programming college class and then maybe switch them to MP if students need it later. These guys are engineers but not "programmers".
pastel panther
I think there shold definitely be better documentation but it's one of those un-glamorous jobs that can easily be an endless supply of work if things are constantly changing and being added
On a positive note, help is always appreciated so if you have an idea for improvement we're all ears. PRs welcome
idle owl
I did a search for "Tony D CircuitPython" and found few videos. They're all titled "CircuitPython: Some Topic with Tony D!" if that helps. I'm not certain that's the direction you want to go anyway, but if it is, it's a place to start.
jovial steppe
I can deal with code-as-docs if I need to. I just need to find them in github if the doc isn't there. I only know enough now to know that the stuff in the flash isn't human-readable (semi-complied, at least).
idle owl
Have you looked at ReadTheDocs?
jovial steppe
Yeah, that's what I just found after stumbling in it from a random tutorial link. I never found a link to it from any top-level CP page. That's been part of the frustration.
Two weeks of poking around just to find the API docs.
idle owl
Ok I see part of the situation. The guide for the Metro M0 Express doesn't really have any examples for CircuitPython beyond Blinky. I would suggest something you already said earlier, which is checking out the guide for the Circuit Playground Express. It has a pretty solid section of CircuitPython examples and explanations thereof. I understand it's for a different board, but a lot of it should be the same, and it might be of some help to you.

You're right that there is not a central location with links to the places to seek out information. There's a welcome to the community guide in the works that references Discord, the Forums, Github and ReadTheDocs.
@jovial steppe Like I said, it's a different board, and some of it won't be applicable to the MM0E, but it might be a place to start. https://learn.adafruit.com/adafruit-circuit-playground-express/adafruit2-circuitpython
@hollow tartan Good catch!
hollow tartan
@idle owl how could we have teased that out of the REPL interface?
idle owl
@hollow tartan Sometimes it fails with things like "int cannot be made into float" or something like that, but otherwise I don't know. I'm not sure if running it through on it's own would have caused it to fail with an error as specific as that.
hollow tartan
recall my test case simpleio.tone(board.D9,222,100) surely did hold a clue.
jovial steppe
@idle owl Yeah, someone earlier was in a similar situation with the FM0E and someone suggested he look at the CPlayEx docs, which I was also going to look into. the CPE is actually reasonably representative of what I'm looking write my diagnostic program for.

hey @tulip sleet , I don't know if you recall the weirdness I was having with my m4 last week but you suggested I try checking out an earlier commit of master and building it to see if that fixed the problem. As it turns out, no it didn't help.
If you have any other ideas I'm game to try them out.
tulip sleet
right, I was worried about USB clocking. DId you try it on that old laptop you had lying around?
pastel panther
Oh no, I didn't. Let me grab it and see what state it's in
pastel panther
welp, it looks like the roaming vortex has claimed the last un-chewed power adaptor for the macbook air
And of course it's dead by now
I can try it with my old work computer tomorrow
Is there anything else I can try in the meanwhile?
tulip sleet
@pastel panther well, you already tried the USB hub, which I hoped might help, but it didn't. I can't think of anything else, short of plugging it into any other computer in the house. (But it sounds like there's only the one functional one now.) I just want to see if CIRCUITPY appears and/or you can get into the REPL. If I remember, you did not see CIRCUITPY, and there was no /dev/tty.usbmodem411.
slender iron
@jovial steppe Trinket guide is good too and holds similar examples: https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/circuitpython
The Metro M0 Express and Feather M0 Express came first, thats why they don't have as many examples.

@hollow tartan what was the issue with your tone code?
hollow tartan
@slender iron \Metro Experimenter Guide\METROX-Examples-and-Project-Sketches-master\circuitpython\CIRC06\piezo_music.py program was using FLOAT values for the note Frequency and simpleio.tone wanted an Integer.
cunning crypt
Does CircuitPython have anything that pulls anything unique but consistent off of the board? IE, serial number, M0 ID, etc
slender iron
@hollow tartan ah! we should fix tone to either handle it or produce a friendly error message. mind filing an issue on the simpleio repo?
@cunning crypt not through python that I know of. we do read the serial number for USB though and could expose it somehow
cunning crypt
@slender iron That would be useful for a potential example. I can absolutely write it without it, but it'd be "Cool" to have it in there. Idea is to show off the fact that Python, in general, can load/modify files on the fly. Idea I had was have the main program create a secondary program based on the unique board it's on.
cunning crypt
Awesome. And I'm about 85% sure there's a self-reset method available somewhere.
slender iron
I think there is an issue to add it

pastel panther
@slender iron is loadbin the correct jlink commander command to use to program a bin to my m4 board? Something like loadbin blinky.bin 0x00 if I'm loading it to a new bare chip with no bootloader?
pastel panther
I was going to but I couldn't figure out the gdb commands to do so
or does running it with a elf like in your tutorial flash it?
Hmm... it seems the obvious load was staring me in the face
pastel panther
@tidal kiln Does a 'CPU could not be halted' error sound like the reset line isn't working?
tidal kiln
that can happen. what's the board?
pastel panther
It's a samd51 on breakout +hotglue etc. I threw together this weekend:
High likelyhood of a bad connection. I'll have to figure out how to verify that unless you know
tidal kiln
oh. not sure then. i've had it happen working with metro m4 express. there's a reset / usb plug / unplug dance that fixes it.
slender iron
@pastel panther yes if its fresh. I've had more success with a hacked arduino zero in that case htan the jlink
if there is code on it then be wary you turned the SWCLK pin off
or stopped the core clock
tidal kiln
jlink should report that it's connected though, even before you try loadbin

Perhaps I should erase first, just in case?
or try to at least
pastel panther
hmm.. I should probably hook up a reset button
pastel panther
Samd issue, it can't do much since it can't stop the CPU
tidal kiln
double resetting only makes sense for the metro with uf2 bootlaoder, not sure how that'd apply to your setup
pastel panther
oh right, I don't think that would do much, though being able to reset it will probably be handy
tidal kiln
yep
pastel panther
hmmm, gdb is acting like it copied it over...
worn birch
random question can I use a pwm to make and led flash like once every 15 seceonds? ... initial thoughts are it is less that 1 hz so likely not
cunning crypt
@worn birch PWM? No, not really.
Checking the board time and seeing if 15s have elapsed, and then flashing the LED would probably be the best
pastel panther
time.monotonic() is what you want, I think
If you were using the timers directly you could make it work but you're not going to get that level of access to the hardware in CP
worn birch
yes ... I tried that ... how to do it so that it ALWAYS does even if the main loop fails ... ie. like a main.py load heartbeat as such
pastel panther
What do you mean by 'if the main loop fails'?
worn birch
the LED setup on pwm of 1hz with 1/8 duty cycle looks ok ... just wondered if I could got lower but pretty sure the freq is an int
so you load main.py it does imports then setup then most likely enters a while loop or state machine ... so if python throws an error I don't want it to stop flashing the LED ... using the PWM solves this ... where as having to call time.monotonic() could fail in the loop
pastel panther
I'm not sure you can do that without modifying the cp code
Oh, I see what you mean
worn birch
yea I figured ... all good 1 hz will work
pastel panther
because if the timer is working on it's own, presumably it would continue even if CP crashed
You would need to aggressively prescale the clock and then use a large period and I don't the CP has that level of access
(though it would be nice)
What is your use case?
worn birch
Long term GPS logger ... with backup battery ... want to be able to use the red led to say hey I'm on I'm working away but not have it drain the battery
I mean at 1mA draw the LED is not my issue ... the flush after every write to sd is a killer
pastel panther
If it's a heartbeat, wouldn't you want it to stop if something crashed?
worn birch
I guess ... versus ... hey im powered ...
touche
While we're talking LEDs anyone use the LED flash rate to pass on user messages ... like 5 hz flashes means an error or two red then green means xyz
pastel panther
CP has pretty involved error message delivery via the neopixel. It can even report the line number of the bug
might be worth checking out

@pastel panther is the metro m4 schematic published anywhere? I couldn't find it on github
pastel panther
@stuck elbow no it's not, though you can find a fair amount out with a magnifier, a multi-meter, the data sheet and a lot of patience 😉
I should probably sketch one up just as a reference though I don't think I have the patience to do the whole thing. I'm kinda just using it to answer questions I have about the samd51
stuck elbow
@pastel panther I was wondering if the big black capacitor-like smd part bwteen the flash and the mcu is the buck converter inductor
or just a really large capacitor
pastel panther
@tulip sleet I tested my m4 with a old mac mini I found and got a similar "can't enumerate" or similar error and had no CIRCUITPY. I forgot to check for CDC but I doubt it was working
@stuck elbow Yes, that's the inductor
the 'schematic checklist' section of the datasheet was useful for that
I think it's a 1008
tulip sleet
@pastel panther if you could try it on a Windows or Linx box, that would be the key test.
pastel panther
Ok, I'll test my old windows box when I get to work
tulip sleet
It's possible there is something broken about the flash memory on the m4. The bootloader is v1.23.1-adafruit.something, right? If there's a bad spot in the flash above the bootloader, then circuitpython would load but would not run properly. That would explain why you see METROM4BOOT but not CIRCUITPY when you load any version of CircuitPython. Otherwise I don't see a reasonable cause for this behavior. But that's an unlikely scenario, so we've got to rule out all kinds of other things.
pastel panther
Yea, that's the bootloader version.
tulip sleet
if you have time before you go to work, load erase_m4.uf2, and then reload a good build of circuitpython 3.x
tulip sleet
@pastel panther testing one...
5eb7958425b026480486c
that's very recent. all the recent ones have been fine on my boards
pastel panther
ok
tulip sleet
you may need to update to get that one
pastel panther
It's back!
tulip sleet
Great?! so what was different?! Maybe the CIRCUITPY filesystem was damaged and the erase fixed it
pastel panther
>>> print("whaaaaat the heck")
whaaaaat the heck
>>>```That's the only thing that makes sense, but why didn't the previous erase fix it?
tulip sleet
I thought you did the same things as previously. Or maybe what you were loading was not really the right circuitpython?!
stuck elbow
folks, does anyone have opinions about merging https://github.com/adafruit/micropython-adafruit-is31fl3731/pull/1 ?
pastel panther
@tulip sleet I think I should try to repro it now, what do you think?
tulip sleet
dunno! If you think you can reproduce it.. do you mean repeat what you just did a few times?
pastel panther
Yea, find whatever commit I had on it and then put it in repel and shut down the computer. I think that's what happened. I had it in repl and I went to sleep and it was borked in the morning
tulip sleet
well, try that with the current commit, since we'd want to test against that.
pastel panther
ok
tulip sleet
@stuck elbow I agree with your comment about the name blit(). I would just call it write() or similar. Looks good otherwise.

Hi, I need a bit of help.
I have a feather m0, circuitpython version. From the factory it came with 0.10.1 and I'm trying to upgrade to cp version 2
silver tapir
I've copied the uf2 file to the CIRCUITPY folder inside the feather, the neopixel flashes for a second but after reload, I still have 0.10.1
Hi @idle owl 😃
idle owl
Hmm. Are you putting it into the bootloader first by double-tapping reset?
silver tapir
I dunno if I have to upgrade to an intermediate version...
idle owl
You shouldn't have to, no
silver tapir
Ohh I see.
idle owl
Because you should be putting it into FEATHERBOOT or something close to that
silver tapir
@idle owl, thanks a lot... double-tap, got it.
idle owl
@silver tapir Sure!
silver tapir
Now I have 2.1.0. No idea how thankful I am.
idle owl
I'm glad we figured it out!
slender iron
@silver tapir how were you getting the version number? We don't ship the feather with circuitpython as far as I know
ruby lake
what ype does a conditional expect a varible to be? I read a characters from a uart, ay rcv = uart.read(1) but then an "if rcv > 0xBF and rcv < 0xF8:" gives a TypeError, "TypeError: unsupported types for gt: 'bytes', 'int'"
~type
glacial bronze
the problem is that bytes and int don't have an implicit cast to be directly comparable
Try casting the byte to an int
silver tapir
@slender iron it is possible I installed CP on that feather a while back.
stuck elbow
@ruby lake conditional accepts pretty much any type, and any "non empty" value will be considered True, but in your case you use a "<" operator, which expects numbers.
@ruby lake try b'\xbf' in place of 0xBF
@ruby lake even better, do rcv=uart.read(1)[0], which will give you the value of the first byte
ruby lake
thanks
slender iron
@silver tapir ah, from may https://github.com/adafruit/circuitpython/releases/tag/0.10.1
opaque patrol
@stuck elbow Is it possible for uart.read(1) to return an empty (null in C++) array? Just curious,
stuck elbow
@opaque patrol let's look at the documentation: http://circuitpython.readthedocs.io/en/2.x/shared-bindings/busio/UART.html#busio.UART.read
yes, it can read fewer bytes than specified, in this case you will get an IndexError — you can avoid it by first checking if it's not empty before applying [0], or by catching that exception
opaque patrol
@stuck elbow I assume None would cause an exception, so you would want to wrap that in a try...except block
stuck elbow
you can do something like:
rcv = uart.read(1)
if not rcv:
continue # Assuming you are reading it in some kind of a loop
rcv = rcv[0]
...
then it will go back to the beginning of the loop when it gets None or an empty bytes object
(I don't think it can return None, though)
silver tapir
Another quick one. I have some of the old rgb led chains from sparkfun. Do I use the dotstar library for this strips?
(example https://www.sparkfun.com/products/11020)
silver tapir
(oh and there is an adafruit ws2801, but for the full (c) python)
@idle owl Ok, let me check how to I define the two pins with this library.
idle owl
Dotstars are APA102 I think. The NeoPixels are WS2182, which is closer? I don't know if it'll work though. It's worth a try!
@silver tapir If that doesn't work, the python library might work with CircuitPython as-is.
silver tapir
Ohh ok. I'll try that.
idle owl
It'll probably need a little tweaking, but we try to keep them compatible.
worn birch
@opaque patrol yea so the uart object returns None if it timesout hence why the if not rcv: works .. it is handy if you want to do a check and then do something if the uart times out such as:
uart = busio.UART(TX, RX, baudrate=9600, timeout=2000)
sentence = uart.readline()
if sentence:
print(str(sentence, 'ascii').strip())
else:
print("No Input - UART timed out after 2 seconds")
@silver tapir I don't know what changed between the WS2181 and WS2182. The NeoPixel library might work as is, or with minimal changes.
opaque patrol
@worn birch yeah, I was concerned about the rcv=uart.read(1)[0] could cause an exception and that it should be handled appropriately to avoid a crash
silver tapir
@idle owl One change is that I need to define a clock pin and a data pin. With the neopixel library I can only define the "in-out" pin and that's it.
I'll try with the c python version...
idle owl
@silver tapir Ah, I see why you were thinking DotStar then. Yeah, give the cpython lib a try
silver tapir
@idle owl (a little example with the arduino library. https://github.com/adafruit/Adafruit-WS2801-Library/blob/master/examples/strandtest/strandtest.pde )
worn birch
@opaque patrol yea then separate into the following:
data = uart.read(1)
if data:
rcv = data[0]
or the response from @stuck elbow works well too
stuck elbow
@worn birch it returns b'' not None
slender iron
@silver tapir you can probably do it with busio.SPI
idle owl
Even better!
slender iron
the dotstar driver sends an extra header and footer that may mess up the colors on that strip
worn birch
@stuck elbow Ok ... so when does it return None ... the docs say the return type is bytes or None https://circuitpython.readthedocs.io/en/latest/shared-bindings/busio/UART.html#busio.UART.read
stuck elbow
I have no idea
let's look at Python's documentation: https://docs.python.org/3/library/io.html#io.RawIOBase.read
no idea if UART is in non-blocking mode by default, though
I guess it is, if it has timeouts
ruby lake
Ideally I'd tie the uart to an isr
hollow tartan
i LEARNED about // math op
ruby lake
but I am just experimenting at this point to see how well I can process midi data
worn birch
Interesting ... so if you get b'' then it is end of file and None if it times out you could check for either condition and then do something useful

Thanks!
tidal kiln
# sum up readings
shake_accel = tuple(map(sum, zip(shake_accel, self.acceleration)))
but something to consider perhaps for the shake detection you're adding, you might find adding a low pass filter helpful in the future if the detection is too sensitive

@timber lion for the lis3dh, you're thinking you'd set it up for detection and then poll the interrupt line?
worn birch
yea ... it is not doing what i expected ... i'll look into further ... so far I haven't killed the card ... hopefully i wont
stuck elbow
funny things may happen if you insert a different card 😄
tidal kiln
@timber lion also, the averaging is essentially the low pass filter
stuck elbow
for some value of funny
worn birch
yea ... maybe I need to look at deinitliasing the sd card on removeal then initializing again after ... just o make sure I don't get them funnies @stuck elbow

@slender iron More like this? # shake_accel creates a list of tuples from acceleration data. # zip takes multiple tuples and zips them together, as in: # In [2]: zip(['a', 'b', 'c'], [1, 2, 3]) # Out[2]: [('a', 1), ('b', 2), ('c', 3)] # map applies sum to each member of the resulting tuple, creating # a single tuple of single members, which is fed into shake_accel # for use in finding the average acceleration
slender iron
it'd be nicer if the example was actual accel values
idle owl
ok
tidal kiln
also:
# map applies sum to each member of the resulting tuple, creating
# a single tuple of single members, which is fed into shake_accel
map return list, not tuple. that's why the tuple() cast is needed
idle owl
oh right. and I guess if we had done shake_accel = [0, 0, 0] we wouldn't have needed tuple() but this is clearer I think.
@tidal kiln so resulting in a 3-member list. tuple converts this list to a tuple which is now used as shake_accel ?
# zip takes multiple tuples and zips them together, as in:
# In : zip([-0.2, 0.0, 9.5], [37.9, 13.5, -72.8])
# Out: [(-0.2, 37.9), (0.0, 13.5), (9.5, -72.8)]
# map applies sum to each member of this tuple, resulting in a
# 3-member list. tuple converts this list into a tuple which is
# used as shake_accel.```@slender iron Better? Also, should I explain the rest as well? Or was that the only one you found unclear.
slender iron
that was my main concern
idle owl
Ok keen
timber lion
yeah totally @tidal kiln the click detection checks the click/tap interrupt bit: https://github.com/adafruit/Adafruit_CircuitPython_LIS3DH/blob/master/examples/click.py
and yeah good point averaging is a good low pass filter
the app note for the chip is really good, check out section 8: http://www.st.com/content/ccc/resource/technical/document/application_note/77/ed/e7/e1/28/5a/45/d6/CD00290365.pdf/files/CD00290365.pdf/jcr:content/translations/en.CD00290365.pdf
it dives deep into how it does click detection
there are actually a lot of knobs to turn to change how it works
tidal kiln
@idle owl tony makes a good point. i was dismissing that approach because cp doesn't have interrupts. but off loading the math (and whatever else) to the lis3dh and then just checking the int pin could be a good approach.
i know there's a latching behavior you can set for the interrupt. and this would allow for free fall, tap, etc.
worn birch
any idea if you could mount the sd card so it is accessible via the CIRCUITPY drive
idle owl
I have no idea how to do that. If that makes more sense, it's out of my abilities. At that point, I should move the code back to the CPX API and call it good for now.
Which is fine, I'd just need to know which approach makes the most sense.
slender iron
@worn birch I was hoping to support that in 3.x but its not going yet
worn birch
so i know when a python function starts with _ it shouldn't be called from outside the class ... but it is doable right ... just could break something if not done without considering the consequences
e.g. if I call _init_card directly on an adafruit_sdcard object after it has been reinserted
idle owl
@tidal kiln @timber lion See my last comment. Is it worth including what we have for now?
slender iron
@worn birch yeah, you can try
tidal kiln
@idle owl @timber lion my two cents - go with what you got, can look at making it fancier later
timber lion
yeah totally agree i like having both options, the software side shake detect and hardware side one with click/tap

what is the pinout for the SPI pins on the Metro M4?
which pin is the gnd on that ICSP header?

the 5V pin is 5V or 3.3V?

PDMIn formatting in RTD didn't update with my change, but when I built it locally it was fixed, and it looks fixed in the code. I don't know what's going on with it, but it is what it is at this point. 😄

which branch?
idle owl
Oh. Good question.
RTD says "latest". None of the change shows up in the rest of the branches on RTD. On Github it looks like my change was pushed to master. It doesn't make sense because the original change showed up there, but when I fixed a typo, that didn't seem to populate.

@worn birch can you post the line thats throwing that?
idle owl
So I'd use pulseio for sending IR from the CPX?
stuck elbow
yes, PulseOut more specifically
idle owl
Yeah I'm not trying to clone a remote, I grabbed someone elses cloned remote code so I have somewhere to start. I'm heading towards using the IR for communication. But they used a very different board.
So I'm trying to hack the code apart.
And failing 😄
I assumed REMOTEOUT but that isn't doing anything, and neither are IR_TX and IR_RX. However, there's also a frequency and duty_cycle defined that are probably wrong.
stuck elbow
I think it's board.IR_TX
idle owl
Ok thank you

REMOTEOUT and IR_TX are the same pin

ahhhh ok, that would have made it easier.

Delete the offending code (it's usually code), and then reset.
split ocean
Maybe we can add words to that effect to the safe mode message?

Worst case, delete the code and reflash CP, but I've never had to do that. I did it the first time I got it before figuring out it's a code issue.

worn birch
@tidal kiln it is occuring when I try remount an sd card after it has been pulled out with storage.remount('/sd', False)
I think the issue is that when the sdcard gets removed it is not auto unmounted ... but if I try call storage.umount(sd_mount) I get an OSError: 1 so ... still trying to work it out
Maybe I need to complete reinitilise the adafruit_sdcard ... catch is I got to work out if that means I have to deinit pins etc ... seems over kill
tulip sleet
@worn birch not sure why the .umount doesn't work but you could also try storage.umount('/sd'). See if that works or if you get the same error. It's looking up the argument in the table of mounted filesystems, either by object or by pathname.
worn birch
@tulip sleet I'll give that a go
worn birch
seems I have killed the SD card detect switch ... I'm now getting True regardless if the SD card is in or out .... it still clicks ... but the signal is obviously not being brought low ... strange ... confirmed it in the REPL ...
worn birch
yea not a happy switch ... it'll do for some more testing just ... so @tulip sleet umount didn't work with the string either
tulip sleet
sorry to hear; please file an issue
worn birch
out of interest though I used
for item in os.listdir('/'):
print(item)
prior to the unmount call and got:
b'sd'
boot_out.txt
System Volume Information
lib
main.py
any idea why the sd is in a byte string?
tulip sleet
it's a minor bug: https://github.com/adafruit/circuitpython/issues/249. I think Scott may have some idea about why.
I think maybe because it's a mountpoint, and it got added to the directory with the wrong object type.
worn birch
interesting thanks
tulip sleet
we appreciate all your testing! testing has been fairly light, and there are a number of use cases we might not have tested. We are planning to add some peripherals to boards on the rosie tester, but haven't gotten to that yet
manic glacierBOT
worn birch
lol .... seems you need to delete the adafruit_sdcard object first then unmount that seems to work ... of course I work that out after raising the issue
no idea why that works though
jovial steppe
Regular filesystems work like that on *nix -- you can't unmount an fs until all of the open handles to files on that fs are closed. So if you've got a resource tied-up that's connected to the fs, that might be preventing the unmount from happening. I don't know if there's a similar paradigm in play here with HW pins vs. file handles.
Err, same type of thing on Win/DOS. If you have a file open on an SDcard/flashstick, you can't programatically eject it.
jovial steppe
Well, safely.
slender iron
haha, adabot released a bundle even though I only changed the build config
solar whale
@slender iron I see the release, but not the bundles. Does it jsut take some time to populate them?
tulip sleet
<@&356864093652516868> The latest adafruit/circuitpython master commit now uses the SPI flash chip on Express boards (Feather & Metro M0 Express, CPX, Metro M4 Express) for CIRCUITPY. This means your internal-flash CIRCUITPY filesystem will not be accessible and may get erased. So if you build and use the new release (see one msg up ⬆), then copy your old CIRCUITPY before uploading if you want to preserve it.
solar whale
@tulip sleet Nice - looking forward to testing this - hopefully tonight.
tulip sleet
@slender iron I was going to do some debugging of clock rates, given @stuck elbow's SPI clock rate bug and some other issues I saw. I'll just try various clock configs and hook them up to pins to measure them. Lemme know if there's anything you're suspicious of in the current impl. 100 kHz SPI and 1 MHz I2C seemed to be accurate but some things get worse from there.
slender iron
@tulip sleet That sounds good if you feel like you have context. Otherwise, it seems like a lower priority than adding more functionality back to 3.x
tulip sleet
@slender iron E.g., I will generate an 8MHz SPI clock and see why it is 6 or 12 on M0 and M4 (can't remember which is which, but both are wrong). I want to make sure the clocks are OK before I work on other clock-related stuff like PWM.
slender iron
ok, I doubt its the GCLKs that are the problem. I assume its the clock generator in the SERCOM
tulip sleet
I think you're right about that. The GCLKs seem mostly ok but there's a LOT of jitter (like 5%) in the DFLL clock. And if I hook up the internal 32 kHz clock to the DFLL so that it has some ref source when there's no USB present, it doesn't seem to work at all.
slender iron
clocks are a huge rabbit hole so beware
tulip sleet
I won't spend more than a day on this. It does sorta work, but I'd like to understand the SPI rate errors.
slender iron
kk
fresh eyes on it will be good 😃
w00t, community bundle is going too https://github.com/adafruit/CircuitPython_Community_Bundle/releases
stuck elbow
so far the spi flash works
@tulip sleet thank you for looking into this. To be honest, I don't much care about the exact clock, I just care about getting it as fast as possible.
slender iron
lunchtime, I'll be on later

@slender iron Are the names for the community bundle correct - a bit confusing?
they have the same names as the CircuitPython Bundles...

If you surround your code with 3 backticks (the one at the top left of your keyboard), it will turn it into a codeblock It can help with readability.
Hmm. Doesn't seem like it should fail. Do you have a lot of other files or libraries on the board? I haven't done enough with i2c to know if that code should cause memory issues.
My suggestions will all be based on other reasons why you'd run into memory issues, unfortunately. But it might be worth checking those as well.

Is the file you're using for the NeoPixel library neopixel.py or neopixel.mpy?

@unique turret @idle owl is this the thermometer from show and tell?
sacred blade
@unique turret NP[0:8] = [blue] * 8 would work. You need to assign a sequence of the same length, so you create a sequence of 8 blue with [blue] * 8. It's still a little bit memory 'heavy' because you're creating this sequence each time. If you want to avoid allocating memory, you'll need a loop:
for idx in range(8):
NP[idx] = blue
Yep!

the idea is to turn on more lights for higher temperature? but also have the color change as well?
