@teal bear pass is a core statement, it doesn't require an import of any modules (including time)

@teal bear I'm assuming you want to just wait a specific amount of time before continuing your script (according to what you said). I'd use from time import sleep then you can use sleep(secs) in order to accomplish that.
teal bear
@charred lake "yes" but you still aren't getting my message: that build of python does not have the time module, I am wondering why it doesn't
import time = ImportError: module not found
charred lake
@teal bear Forgive me for the understanding, as your demo didn't show any errors.
misunderstanding*
@teal bear I found the problem
@teal bear MicroPython uses utime instead of time. So you would use utime.sleep(secs) instead. According to the official documentation.
pastel panther
if you want your code to work on both, you might try something like:
try:
import time
except ImportError:
import utime as time
Good advice!
teal bear
that's what I was looking for.. well. now I am curious why MP named it utime
pastel panther
any saleae users around? I'm having an issue with mine where it's being finickey about how it calls bits on digital channels
stuck elbow
@teal bear because it doesn't contain all functions that the python time module contains, the idea was that you could provide a time.py that implement all python functions
teal bear
@stuck elbow ok, that makes enough sense.

@pastel panther and @slender iron - figured out my issue. thank you for the help! For anyone else that encounters this or wants to flash circuitpython on a custom SAMD21 board: you'll eventually want to build your own bootloader from a modified adafruit one, but start with the m0_basic from here: https://github.com/adafruit/uf2-samdx1/releases/tag/v2.0.0-adafruit.5, then flash it to the board using a JLink. plugging the board in should now show up as a flash drive. now double tap reset pin to GND in order to put the board into bootloader mode. Finally, use BOSSA and upload the firmware for the m0_basic from here: https://github.com/adafruit/circuitpython/releases/tag/3.0.2 but make sure to set the offset to 0x2000
pastel panther
@lime trellis Awesome job! In the future, for loading cp you don't need to use BOSSA; you can just double tap for bootloader mode and copy the .uf2 release for your board into the WHATEVERBOOT drive that shows up
@lime trellis Did you isolate a particular issue that you had to solve?
lime trellis
@pastel panther the key for me was getting the right bootloader flashed via JLink (I used Atmel Studio 7 with no problems)
Do you have a link to your github with any examples of how you ported CP to your own boards? @pastel panther
pastel panther
@lime trellis I can push it if you give me a minute but the config files might be a bit out of date; I think they changed some things since I last built
lime trellis
that's fine. I'm just curious how you went about modding the repo
(pin outs, etc...)
pastel panther
all the fun stuff is in ports/atmel-samd/boards/
lime trellis
wooo thank you!!!
pastel panther
you'll want to copy a similar board directory and modify as needed to specify where your dotstar/neopixel is, if you have a crystal, what type of flash chip you're using, etc
that's all in mpconfigboard.h
board name and usb stuff flash yes/no and chip stuff is in mpconfigboard.mk
pins.c defines string names for your pins to be available like board.PINNAME
lime trellis
gah so helpful. can't wait to dive in. Thanks again
pastel panther
mpconfigboard.h also defines which pins that shouldn't be available to users, like the ones your using for your flash and neopixel
glad to help! I'll be back in a bit if you have any quesions, but it's fairly self explanitory
when you're done with an initial pass at the config, you'll make BOARD=<your_board_dir> in ports/atmel-samd and you should be rewarded with a firmware.uf2 that you can copy over when your board is in bootloader mode
bbiab
tulip sleet
@lime trellis you can set the BOOTPROT fuses so that the bootloader can't be overwritten by bossac writing to offset 0x0000. The easiest way to do that is after loading the bootloader with the j-link, load the identical bootloader again by copying the "update-bootloader....uf2" generated by your build to the ...BOOT drive. That will reload the (identical) bootloader and set the BOOTPROT fuses when iti is done.
velvet oasis
Is there a rotario position reset method?
slender iron
@velvet oasis no, we expect you to do it yourself by storing the "start" position if needed
solar whale
@pastel panther did you get your salea issue worked out? If you can describe the issue, I'll take a look - won't be until this evening before I can get to it though.
raven canopy
@lime trellis you can also set the BOOTPROT fuse in Atmel Studio. Its in the Device Programming->Fuses window. They seem to have changed the way the value is displayed since the last time I looked on a SAMD21; mine is currently set as 8192 Bytes on an ItsyBitsy M0 Express.

@marble hornet those are just listing the IO multiplexing values from the datasheet (Table 6.1).

If I want to leave expandability for a camera should I avoid the pccs?
raven canopy
Are you thinking that those headers/pins are only for the PCC/TCC? I'm pretty sure that isn't the case; its just documentation of the IO mux.
If you look in samd-peripherals/samd/samd51/pins.c, you'll see how each pin is structured with it's particular peripherals. https://github.com/adafruit/samd-peripherals/blob/master/samd/samd51/pins.c
marble hornet
in software is blob like the bwos? and thanks i'm skimming now.
pastel panther
@solar whale I don't know that I got it fixed but I understand it well enough to work around it. In short when I run a channel in digital mode, some times it calls individual bits "off" from my perspective because the voltage change from high to low is either lagging or leading the clock ever so slightly. For example a 1 might be called a 0 if at the leading edge of the clock the it had only made it to 1.45v but was shortly thereafter above 1.5 or whatever the threshold is for calling high/low.
@uncut coral Even if the voltage it's reading is correct and either the clock or the data line is off, it doesn't matter to the sensor because it's strobing on the falling edge of the clock where the signal is stable so it doesn't see the issue. I was hoping someone would know if there is a way to change the parameters of where/how the saleae "decodes" the voltage. So far all signs point to no because I haven't found anything in the saleae settings and even then as far as I can tell it's only looking at the voltage of the given channel to determine high/low so there isn't a way for the "channel decoder" to look at at the clock and change where in the clock pulse it takes the value of the data line.
Perhaps I can write an analyzer to do that
</novel>
solar whale
@pastel panther you are well out of my “comfort zone “. I’m surprised you can’t get it to decode in the same edge the sensor is using. I can’t try anything until tomorrow. I’d like to see if I can reproduce the issue.. what sensor and protocol are you seeing this with?
pastel panther
@solar whale I'm working on the driver for the MAX31856 and testing with my feather m0 express
Let me look at the captures; I don't recall if the issue showed up with the arduino version or the cpy version.
solar whale
Are you using the SPI analyzer?
pastel panther
It looks like the logic only stores the captures for you current session when you use the little magnifying glass icon
yea, that's how I noticed it. It was showing things being written to the wrong address or sending an incorrect value
solar whale
So is the sensor not working or is it just the salae that is wrong.
pastel panther
The sensor is working and I'm not convinced the saleae is wrong, it's just interpreting the data differently from the sensor
Now that I think about it, it's probably the SPI analyzer that's the issue
I just found a promising setting: "data is valid on clock leading/trailing edge"
😃
solar whale
Does the sensor use a different SPI mode than the sales is configured for
pastel panther
I think so
solar whale
👍
pastel panther
It's calling it CPHA
Yup, just verified with the datasheet "CPHA bit polarity must be set to 1"
Mystery solved!
solar whale
Yay!
pastel panther
Thanks for helping me think through it
solar whale
I like playing rubber duck!
lime trellis
@pastel panther successfully built a port of circuitpython for my custom boards and have it reading sensors over SPI. thank you for all your help!
pastel panther
@lime trellis Glad to hear it and glad I could help. Welcome to the "why not put CircuitPython on it?" club 😃
lime trellis
right?! it'll be great to use on some upcoming projects
one question through... what's the deal with interrupts?
pastel panther
@lime trellis Does your board have a micro usb on it? I'm trying to hunt one down that doesn't fall off when you look at it crosseyed
the deal so far is that they're not supported; I believe asyncio is in the works
lime trellis
yes I do- lemme grab the part number
and that's a real bummer- internal interrupts as well?
pastel panther
@slender iron or @tulip sleet would be better able to answer that question. As for why they're not supported, CP is really targeted at first time programmers. I believe the thought is that interrupts are a bit confusing. Not my decision, just something I came across in a similar position
lime trellis
@pastel panther I'm using 10118194-0001LF microUSB connectors and really enjoy them
pastel panther
That part number looks like an amphenol?
pastel panther
Lol, I think I have the same one in my digikey cart
lime trellis
I've tried a ton of different kinds and eventually settled on that
I have a lot of undergrads working with my boards so they've had some good stress testing
pastel panther
Adafruit uses one that is almost identical but it also adds pins that go into holes in the board under the connector; can't find them anywhere though. I'm thinking the two large pins in the back are key.
Cool, thanks for the feedback.
lime trellis
Oh it looks like interrupts are well underway (if not implemented?) : https://github.com/adafruit/samd-peripherals/tree/d0dcba251c27f629c0a89b5ced4433dd0a609ca3
pastel panther
Interesting;
@lime trellis
https://github.com/adafruit/circuitpython/blob/master/.gitmodules#L70
pastel panther
@lime trellis Looking at the code, I think that submodule is only used internally for things like pulseio and rotaryio
lime trellis
@pastel panther hmm but I should still be able to call it, right?
pastel panther
@lime trellis Not from CP I don't think. There has to be some additional C code that wraps the functionality in python objects.
slender iron
@lime trellis we use interrupts in the C code but not directly from python because concurrency is hard. what are you thinking about using them for? Could you write a C module for it?
pastel panther
hey @slender iron I'm working on the max31856 driver, specifically on the thermocouple type setting code. How should one specify a thermocouple type? Currently I have it as bns_max31856.ThermocoupleType.K etc.
Does that make sense or should the constructor and TC setter take "K" or something else? And when using the getting for the TC type, should we return the actual value that we use in the register or something more friendly?
slender iron
I
I'd do the constuctor since its not going to change
having the arg be an enum is good
why would you need to read it back?
lime trellis
@slender iron end goal is proper handling of RF packets via Radiohead with external interrupts. Also need to access to some internal timers for a watchdog loop
slender iron
the rf stuff probably needs a c helper to handle the interrupts
why do you need a watchdog?
pastel panther
@slender iron now that I think about it, I was following the arduino driver too closely no need for accessors
lime trellis
have a board with an external watchdog that needs to be pinged every second or it pulls reset low
pastel panther
true; people are not likely to switch TC types in the middle of a program
;P
Is the functionality from the arduino driver a good starting point? There is other stuff it can do but I assume that can wait until someone needs it?
slender iron
@lime trellis interesting! you may want circuitpython C pings or ones from python
@pastel panther when in doubt start small and simple
just a temp sensor 😃
pastel panther
@slender iron but... but.. look at this datasheet! 🙀
slender iron
exactly 😃 its scary
pastel panther
Once you've read it like 100x it gets less daunting
lime trellis
@slender iron what's the high-level process for implementing a custom c module? sounds like I can get away with making my own library and just interfacing with it via with the __init__.py that I see used?
lime trellis
excellent thank you! that's more or less the descriptions I was looking for

Can anyone tell me why my ConsumerControlCode is not working? https://pastebin.com/gYCnCyui
tidal kiln
@rustic nymph not working how? not running? getting error messages? running but not doing anything? etc
rustic nymph
In the pastebin configuration, volume does not go up and I eventually get a memory allocation error
tidal kiln
does volume go up if you write a simple code, or even just try in REPL, to do just that?
kbd.send(ConsumerControlCode.VOLUME_INCREMENT)
rustic nymph
does not work in REPL
if I use cccode.send(ConsumerControlCode.VOLUME_INCREMENT) I get AttributeError: 'ConsumerControlCode' object has no attribute 'send'
which appears to from there? but I dont know what consumer_control is
tidal kiln
cccode is your ConsumerControlCode object, it doesn't have send - that's in the Keyboard object:
https://circuitpython.readthedocs.io/projects/hid/en/latest/api.html#adafruit_hid.keyboard.Keyboard.send
tidal kiln
looks like there are two very similar named classes:
ConsumerControl
ConsumerControlCode
your pastebin has this:
cccode = ConsumerControlCode()
and ConsumerControlCode is just a collection of constants
rustic nymph
I keep getting Traceback (most recent call last):
File "main.py", line 53, in <module>
File "adafruit_irremote.py", line 217, in read_pulses

tidal kiln
try this set of commands:
from adafruit_hid.consumer_control import ConsumerControl, ConsumerControlCode
cc = ConsumerControl()
cc.send(ConsumerControlCode.VOLUME_INCREMENT)
d'oh. sry. wait. looks like ConsumerControlCode is in a separate module...
this:
from adafruit_hid.consumer_control import ConsumerControl
from adafruit_hid.consumer_control_code import ConsumerControlCode
cc = ConsumerControl()
cc.send(ConsumerControlCode.VOLUME_INCREMENT)
that works
Is there a way to open and read mpy files?
it looks like this in notepad https://i.imgur.com/TbzQNyM.png
tidal kiln
don't think so. not easily. which one are you trying to read?
easiest is to just look at source code in the repo
rustic nymph
Serial says the error is in adafruit_irremote.py but the one in lib is .mpy ?
tidal kiln
might be a quirk. you don't have a copy of both on your board do you? both the .py and the .mpy? (doesn't look like in your screen cap)
rustic nymph
no
tidal kiln
@slender iron see above - why does stack trace from a .mpy refer to .py?
slender iron
cause the filename is baked in by mpy-cross
tidal kiln
that's what i figured. i can see how that's confusing though.
esp. since it gives the line number.
@rustic nymph the .mpy files are like "compiled" versions of the .py files, and mpy-cross is the program used to generate them. this is done to save space - the .mpy files are much more compact. when you download the bundle, it contains the .mpy versions for this reason.
rustic nymph
Ok
I loaded my old code copy without all the changes and it not longer gives that error
this one works with up/down https://pastebin.com/k1kZE1ky
Thank you @tidal kiln
How did you know this line was required? from adafruit_hid.consumer_control import ConsumerControl
because of class adafruit_hid.consumer_control.ConsumerControl ?
tidal kiln
i worked backwards from the class you actually needed for what you are doing
which is ConsumerControl
here's the source:
rustic nymph
tidal kiln
@rustic nymph i think that code snippet in the documentation is somewhat incomplete
i think it was taken from longer code
and somewhere in that longer code there was probably a line that had the import:
from adafruit_hid.consumer_control import ConsumerControl
and then soon after that a line that created an instance:
consumer_control = ConsumerControl()
in your code, we called it cc
rustic nymph
Thank you
I think I'm going to try to use the NEC Keyboard Example as it has much smaller pulse matches
So I'll try to butcher that sequence into that code shortly 😄
tidal kiln
cool. good luck!
rustic nymph
python is rough when you come from vba
there isnt a way to run the other code examples without renaming them to main correct?
tidal kiln
you sorta can - just import them from REPL.
to run foo.py:
>>> import foo
however, to "run" it again, you would need to first do a soft reset with CTRL-D. a second import would not simply run it again (for the same file)
rustic nymph
I get that memory allocation error even with the included example

or some subtle change maybe, from the one you got to current version of CP
rustic nymph
I used the one from https://github.com/adafruit/circuitpython/releases/tag/3.0.2

when did you order it?
rustic nymph
for pirkey
the other one I got has Adafruit CircuitPython 2.2.3 on 2018-02-05; Adafruit pIRKey M0 with samd21e18
I ordered it friday from Digikey
tidal kiln
you updated the firmware yourself?
tidal kiln
File "adafruit_irremote.py", line 217, in read_pulses
and "occasionally"? i can see why maybe - there's no check for the current size of received, so if you keep feeding it pulses, it will append until it runs out of memory
rustic nymph
do I need this at the end of while: True - pulses.clear()
pulses.resume()
that was used in one example I found but it was outside of the while loop
well that does not help...

Guys, are there plans to provide CircuitPython support for the Adafruit Mini Color TFT with Joystick FeatherWing? https://www.adafruit.com/product/3321

if you had last done makecode i think it's different,were you only doing CP stuff?
cunning crypt
@tidal kiln That is correct.
tidal kiln
@gusty topaz eventually, the necessary graphics support is currently in development
cunning crypt
@gusty topaz It's Seesaw, so there's already the CP seesaw library. And the ST7735 driver exists under RGB display.
So, it CAN work, but there's no example code currently
gusty topaz
@cunning crypt Really?.. so I should work by using those two libraries?
cunning crypt
I believe so, yes.
What @tidal kiln said implies that the RGB driver might not work for that display. I don't have one so I can't test.

Is the memory for these device super expensive or something?
tulip sleet
@rustic nymph it's just how much RAM is available. 32kB is the max included on-chip on the Atmel SAMD21 chips.
imports, even of .mpy files, use RAM. to hold the bytecodes. Only frozen libraries do not use (significant) RAM on import

Quick question (may be a stupid one)... does it take more RAM to import a full module vs an element in it?
from adafruit_hid.keyboard import Keyboard
VS
import adafruit_hid.keyboard
@pastel panther We found the M0 can use better pull-up/capacitance on the Reset button as well (right @slender iron?)
rustic nymph
What does the asterisk mean in this? keyboard.press(*pairs[1])
forest glen
SgtSarcasm - it unfolds a list typically
so if pairs[1] is actually [1,2,3] it would be like calling keyboard.press(1,2,3)
rustic nymph
That line was ([255, 2, 127, 128],(Keycode.SPACE,)),
I guess in this line it would push both buttons? ([255, 2, 191, 64], (Keycode.LEFT_CONTROL, Keycode.UP_ARROW)), # Vol+
forest glen
like this
def test(a, b, c):
print(a)
print(b)
print(c)
if __name__ == '__main__':
test(*[1,2,3,4])
because pairs[1] would be (Keycode.LEFT_CONTROL, Keycode.UP_ARROW)
forest glen
@rustic nymph - Yeah... it would unfold those values into positional arguments given to keyboard.press()
rustic nymph
Thank you
So I guess when trying to program these I need to read python documentation for the general coding and circuitpython.readthedocs for the libraries?
forest glen
Which checks out... seems to take control key followed by actual key if used positionally
Probably so 😃
It's a subset, so standards should be the same
You see the * notation most as:
def test(*args, **kwargs)
rustic nymph
so circuitpython 3.0.2 = which version of micro/python
forest glen
single * is for list, double is for dict

forest glen
Err... silly autocomplete, meant @rustic nymph not @Shaggy, sorry
rustic nymph
Well thank you!
forest glen
😄 No prob... and looks like latest CircuitPython based on MicroPython 1.9.4 (latest) which seems to be ~py 3.4... I can't find anything more specific. But given the changes in Py 3.5+ that sounds reasonable
@tough flax - It doesn't matter. The whole module is always loaded.
Take this test.py for example:
def a(v):
print("a: " + v)
def b(v):
print("b: " + v)
print("loading test.py")
If you use import test or from test import a the serial console will still show loading test.py
So regardless of which format you use, the test module is always completely loaded.
Just the way the interpreter works... in order to have a handle to a() it needs to have a handle to test which means having it in memory. A lot of that is because a() may call another method or resource in the module, which means all that needs to be in memory. Since it's interpreted at runtime python doesn't know for sure or check what may or may not be needed.

I'm having some trouble running the default example on a ItsyBitsy M0 Express. This is my first experience with CircuitPython.
First I installed the latest uf2.
version 3.0.2
Then I got an error saying that the mpy files were incompatible, so I downloaded the latest adafruit library bundle.
Now when I run my code I get the following error:
Traceback (most recent call last):

File "adafruit_hid/keyboard.py", line 35, in <module>
MemoryError: memory allocation failed, allocating 906 bytes
It works if I don't initialize the HID module.

Hey folks!
Bluetooth.
I've seen references (like this [1]) that suggests you guys are working on Bluetooth support. I know that Damien George is also looking into Bluetooth support, particularly since he's announced the new PyBoard [2] with onboard Bluetooth HW. Some other contributors to mainline MicroPython have begun an implementation too that is currently performing basic advertising on ESP32 and NRF52 (some details: [3]). Damien has reached out to work with those folks. Further, Boris, of the ESP32 Loboris fork fame [4], has also begun looking into it [5].
It seems like we have an opportunity here. :)
Is it possible to work more efficiently together toward a common goal? I'm not particularly well-versed in Bluetooth but I'm happy to help everyone communicate...

is it possible to control EL Wire with CircuitPython?
forest glen
@stoic marsh - You would need an EL Wire controller capable of controlling the inverter output from a GPIO pin, in which case it's just standard GPIO control from Python
As far as I'm aware / can find, Adafruit doesn't sell an inverter than can be controlled in this manner.

You could, however, create one with a MOSFET that drives the inverter

@clear halo we are working on a port to nRF52832 and '840: that's the primary goal of the 4.0 release. There's already an alpha, but with no bluetooth support yet. . See the long discussion about the BLE API in this issue: https://github.com/adafruit/circuitpython/issues/586. The existing API's (bluepy, etc.) are not necessarily the model we would follow for the end-users we have in mind. Our goal is ease of use, especially for beginners.
We have differed from MicroPython in how the I/O libraries are structured, sometimes stylistically, sometimes more deeply. For example, we use properties extensively, which MicroPython has avoided for performance reasons (though I think the performance difference has narrowed somewhat due to recent improvements in property dispatch).
A wrapper library can usually be written to convert one API to the other.
indigo wedge
The new BLE API has already been written and will soon hit review so if MP folks want to drop by and see if they like it, I guess that's an option.

@forest glen re: build-bundle - i don't see anything that jumps out precluding Windows use. easy workaround is WSL of course. I've never even attempted to run it, Windows or otherwise.
forest glen
@raven canopy - NamedTemporaryFile is the culprit, at least one of them. It's broken IMHO for Windows. The problem is that it actually opens and returns a file object immediately. But many people use it "wrong" by then taking only the filename that it generates and then opening the file manually. This works on *nix systems but Windows disallows multiple open calls to the same file from the same process.
I actually was able to patch those parts enough to get them to work on Windows, but then once I ran it the whole thing just silently failed. Worked fine in WSL and on Fedora but nothing on Windows. After further digging I realized it's a complete non-starter since mpy-cross requires make to build which Windows doesn't really have. I'm sure there's a way to create a Windows compatibly makefile, but it was clear that it was never intended to work on Windows. So I gave up.
I jump back and forth between Windows and Linux depending on what I'm doing but I try to have as many tools as I can on both. WSL seems to work fine for now but everything is working beautifully on Fedora 28 as well. So no worries.

Hi folks... I'm going to have to program lots (about 100) Trinket M0s with both the latest (stable) CP build as well as a CIRCUITPY volume that has a main.py and a number of support files. Is there a way to make a single image (UF2 file?) that I can use to push both the CP and the python code to the device? I'm working on WSL but could use a RPi if that makes it easier.
tulip sleet
@tough flax If you copy CURRENT.UF2 from TRINKETBOOT, that will include both CircuitPython and the contents of CIRCUITPY. This works only for the non-Express boards like Trinket M0 and Gemma M0.
tough flax
Gotcha! So, I configure one trinket m0, test it, then put it in bootloader mode, grab the CURRENT.UF2 and then copy that down to the rest?
tulip sleet
right, exactly! (test of course)
tough flax
That makes sense, and is a perfect answer: but it makes me wonder why pulling a new UF2 from a fresh build doesn't wipe my main.py?
Does it check to see if one's there?
tulip sleet
because the .uf2 files describe which parts of flash memory should be written, and the CIRCUITPY part is not overwritten by the normal adafruit-circuitpython-blah-blah.uf2. But the CURRENT.UF2 represents all of (internal) flash
this is also a great way just to back up your trinket or gemma

It sort of says it here: https://learn.adafruit.com/adafruit-gemma-m0/circuitpython but not really explicitly. I could add that more explicitly somewhere.

Hi,
I've got a peculiar problem on my hands. I have about 200 Trinkets M0s running in a project of mine. They are usually grouped in a cluster of 25 per one power supply (24V) and each has its own 24Vto5V step down converter. Each Trinket is controlling about a 100 DotStars. Now when I power them up 9 out of 10 times they just turn on but that 1 time the on board dotstar just starts flashing yellow and the controlled dotstars get stuck on some random colour/pattern.
I'm unable to replicate it when connected to USB so I have no idea what's going on...
Any insight?
idle owl
Presuming you're running CircuitPython, when's the last time you updated the CircuitPython version running on them?
timber mango
It's running the most up-to-date 3.0.2 and the dotstar library is from the latest bundle. On all of them.
idle owl
Ok hmm. Only flashing yellow? No cyan or anything else?
timber mango
nothing, just yellow pulsing in loop, when I press the onboard switch it reboots and everything is fine... And I just cant replicate it. I've tried multiple times, it just starts up. I'm using the same power supply and everything...
Is there a way to log stuff on-board? Or do I have to get some SD card adapter or something?
idle owl
I think yellow means it's in safe mode, and I think that was our solution to a previous power brownout / bobbled power on startup bug where it would wipe the board if the power shifted too low (i.e. a battery dying or if the power shifted when receiving power on startup)
So that was my first thought
You can log stuff on-board, but you have to set the file system to writeable by CircuitPython and it can't be writable by your computer and CP at the same time, and you'd be limited on space on a Trinket, so an SD card would be better
tidal kiln
idle owl
So, just this past week we had one of our new boards hooked up to a battery and when the battery drained, it started going into safe mode on startup. So I'm wondering if there's something going on with the power connection or something, and that USB power is being more reliable and that's why you can't repro it on USB
tidal kiln
i'd second power being probable cause
timber mango
Hmm, I find it hard to believe the powersupply would get too low. The stepdown converter is actually 32-9V and the power supply is 24(.1 or so)V and the amperage is about 1/3 of what we would need on full power... So even if all the Trinkets and DotStars took too much it shouldn't dip below such trashhold.
tidal kiln
it could be a very brief transient happening at initial power
timber mango
(32-9V on input that is, the output is 5V to the trinket, the level shifter and the dotstars)
Hmm, I might hook it up to my voltmeter during startup and log it to PC or something. It should show the power dip if it occurs.
Or how about hooking up a bigger capacitor either in front of the power supply or in front of each the step down converter? Would that help?
tidal kiln
it may even be too fast for a voltmeter, you might need an oscope
maybe on the capacitor, and i guess i'd put it at the input to the trinket
depends on the nature of the problem
tidal kiln
if the issue is it's not coming up to required voltage level fast enough, then it wouldn't help
timber mango
very well then, thank you all
tidal kiln
np. good luck. sounds like you have an awesome setup - 200 trinkets 😲
100 dotstars per trinket.....math......number of dotstars = 😲 😲
do you have a link to what this is? it must look cool.
timber mango
I would like to provide a link or some form of documentation but it's a custom setup for a private customer 😕
All I can give you is one pice of advice, the DotStars from the ORIGINAL manufacturer are WELL worth the price and are nearly indestructible (like running 120+ °C on full power for multiple days etc.). The Chinese knockoffs on the other hand are a complete and utter garbage. 😉
Also from 250 Trinkets I've ordered for this setup only one was dead which is a pretty impressive feat.
You might want to hack the oscillator supervisory code/settings/registers.
But aren't the safeties in place for a reason? As in if I change or turn them off the internal memory might be wiped clean when the voltage drops?
your SRAM is wiped anyway and the flashROM isn't going to be wiped except by command.
My Dad used to start up his saw (late 1960's) and the lights in the house would dim until it got past the initial hurdle (big saw).
I haven't seen that in a long long time, since.
I would program in a delay for each system running in parallel so they don't all apply their load to the power bus at the same instant.
The delay won't be largely sensate in a human time frame.
tidal kiln
@timber mango you say the yellow is pulsing / flashing? that might mean it's indicating a runtime error, not safe mode. but it should be followed by other colors that are trying to indicate the line number.
(see previous link for RGB status info)
timber mango
How many times would the yellow flash before the line info? The longest I've let it flash was for a minute or so.
tidal kiln
can't remember, but only like 5 quick flashes, def not minutes
timber mango
That's not it then. Also that could be recreated on USB which I wasn't able.
Don't get me wrong my code is by no means perfect and it crashes from time to time but when it does it just resets and everything runs again.

so now instead of importing just the mcp9808 library we need to import board and busio?
sorry, just a hobbyist so i have trouble keeping up with this stuff

status RGB should be green and red LED pulsing (i think)
tawdry wyvern
It looks like it tries. The NeoPixel flashes red and then goes back to green.

Hey guys/gals, bought afresh 8266 huzzah from microcenter/denver today and a new laptop, installed the drivers and downloaded espflasher(used many times) and the .bin file for CP 3.0 seems to flash just fine but when I restart the esp the blue light just flashes rapidly and I cant connect via serial
tidal kiln
@modest atlas try with esptool:
https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-for-esp8266
tawdry wyvern
@tidal kiln Actually. I'm getting a Flashing green NeoPixel, nothing on the Pin 13 LED and a fast yellow flash on the CHG led on the other side of the micro USB. Does the dead #13 pin give any clues?
tidal kiln
the fast yellow CHG led is normal
the other two seem like it's not going into bootloader
i just grabbed a feather m4 express to verify
i'm in bootloader mode and have steady green neopixel and pulsing #13
and crazy flashing yellow
tawdry wyvern
Hmmmm.... This is my first Feather M4. All of my ItsyBitsy's have worked just fine out-of-the-box. (At least until I do something unfortunate to them. 😐 )
tidal kiln
tawdry wyvern
Interesting. I'll give it a shot!
tidal kiln
i just tested what bootloader does with a charge-only USB cable - red neopixel and fast pulsing #13
the fact that you can connect to REPL makes me think it's not the USB cable
@idle owl dotstar PR tested and merged. should we make a release or wait for other PR?

@stuck elbow I know there have been issues in the past but we are doing our best to be easier to work with. Please let me know how I can do more!
@crude fossil We can indeed!
@tulip sleet Thanks, that's really useful information! It makes the purpose of the 4.0 release much clearer. I've reached out to those that I know are actively looking at Bluetooth and asked them to review and provide feedback on your ticket. That said there's not a lot of content in that ticket...
I understand the differences in the implementations though I do wish there were less. Today it's very difficult to write a driver that's compatible with both CircuitPython and MicroPython. That's a shame for both communities. My opinion is that wrapper libraries are nice but add complexity and will only be used initially; it's more likely that drivers will be ported back and forth between the dialects. Which is not great for users and especially not for driver authors.
I'm not sure we can pull the dialects closer together now but I'm hopeful we can reduce the divergence where possible in the future. And that shouldn't be a one way street - I'd like to think that MicroPython can be flexible too. I'll do what I can to communicate in both communities!
@indigo wedge Is there more to review than what's been added to #586? I'm aware of the NRF ubluepy module but, if I understand, you're moving away from that? I guess I'm looking for an api proposal to discuss. We are aligned in that there is likely to be multiple api's at different levels of abstraction; Damien drew an analogy to sockets vs requests recently which I thought was a good mental model.
A few of the MicroPython devs started a document which began discussing the Bluetooth implementation, please take a look, there's hopefully some useful information there - and feel free to add comments:
https://docs.google.com/document/d/1ApQzdjPdRzBn2Texm4d3Vs3tEsVOU-vdV00TU08KaBg/edit?usp=sharing
@slender iron It's a good question - how can we all communicate? Everyone seems to be spread all over the place: Discord, Slack, IRC, Forums, Google Docs, Github issues and good ol' email. It does seem like we need a single place to discuss this api...perhaps a dedicated discord channel? I can see if the main MicroPython devs could congregate in one place...?
And yeah, I understand that the priorities differ. I know you folks have a strong focus on beginners whereas I (can't speak on behalf of Damien) want MicroPython to take over a large portion of professional embedded development. Those two perspectives are different and will generate tension - but I think we should strive to limit the differences. That's what I'm trying for anyway!
(sorry for the long posts!)

@clear halo I don't think anyone will mind the length. all good stuff/discussion. 😄
idle owl
@tidal kiln I guess we can wait. Probably makes sense to.
slender iron
@clear halo The GitHub MicroPython issues are likeliest to get everyone on board. We tried Gitter briefly but it didn't catch on.
I'm skeptical though that we'll find agreement prior to implementation. My guess is that the most used API will result from other factors like documentation quality.
If the audience of CircuitPython and MicroPython is so different, then why does it matter if the APIs are different?
raven canopy
@idle owl i didn't get FRAM I2C finished tonight; documentation always takes too long. please, please don't delete my shiny new repo... 😆
stuck elbow
@clear halo thanks for the information. I'm not really actively developing anything for MicroPython, so I have no issues. I'm just naturally pessimistic. I will be sure to give the community another try when I have more time.

Hello, im new in circuitpython and i been triyng to do a code that my trinket m0 write on the screen, just like a rubber duck, but i can`t find a way to do that, all the codes that i found are in arduino and those codes dosent work, can anyone help me? (sorry about my bad english)
raven canopy
@gloomy kayak Welcome! We're glad you're here! This guide should help you. It uses a Circuit Playground Express ("CPX"), but the code for the USB_HID (adafruit_hid) will work the same on a Trinket M0. Let us know if you need any additional help.

hey y'all! i just got a trinket m0, and i'm trying to set up a project on it, but the project requires putting some stuff in the "trinketboot" folder, which i'm not seeing. i've already reset my computer, un and reinstalled the arduino interface, reset the trinket a couple of times and done disk refreshing on the command prompt, but i'm still not seeing it. is there anything else i can do? i'm running windows 10 btw
solar whale
@west bridge to get to the bootloader “double tap” the reset. Two resets very quickly.
west bridge
is it supposed to showup right away? because i'm still not seeing it
solar whale
should show up right away - just digging out a trinket - just a sec.
west bridge
thank you! i'm really soryr i'm new to this kinda stuff
solar whale
after the double-reset you should see leds on either side of the USB connector - green led on -- red led pulsing.
west bridge
yep! what i see is the green on always and the red pulses for like ten seconds and shuts off
solar whale
hmmm - it should not shut off....I don't have a Window system to check but something is not right.
west bridge
should i try and install the drivers? a guide said not to but that might be something
solar whale
what project are you doint - what are you trying to copy to TRINKETBOOT
solar whale
I would not install any drivers -- most likely you have to remove some -- any Windows 10 ussers online taht can help?
what is currently on the trinket - have you ever been able to write anything to it?
west bridge
im trying to copy the hekate files onto there, there's a current.uf2, an index and a file called index_uf2
i haven't, it's new
solar whale
OK - after a RESET, it should boot to Circuit Python and you should see a CIRCUITPY folder. ON a RESET, does the GREEN Dotstar pixel flash green?
single RESET
west bridge
a circuitpy on the file manager?
solar whale
yes
west bridge
im not seeing it after a single reset
i have another pc i can try it on to see if its just an issue with mine
raven canopy
@west bridge that project is Arduino, not CircuitPython, so #help-with-projects might be a better place to discuss. having said that, in that repo's "Build" instructions, it fails to mention that you need both the Arduino SAMD and Adafruit SAMD board support packages. I would check that; iirc the Arduino IDE doesn't always throw an error for that.
EDIT: the repo actually does mention it (not sure if required: Arduino - Boards SAMD)
solar whale
what does the DOTSTAR LED do
west bridge
oh ok! sorry i just assumed it was circuit python because the trinkets circuitpy
solar whale
The trinket M0 supports Arduino and CircuitPython -- still you should see the CIRCUITPY folder on a aRESET or the TRINKETBOOT on a double RESET.
west bridge
update: i just tried it on my other computer and i had the same dimming issue
solar whale
once you install that project -- CircuitPython will be gone,but you can put it bac any time.
dimming? -- on a single reset is the RED LED pulseing? -- there is a Dotstar LED in the middel of the board - on a single reset - what does it do?
west bridge
i've never seen that turn on! what i have seen is the red led, which pulses for about ten seconds then shuts off (the dimming issue, that happens with both one and two), and the green one
idle owl
@raven canopy I'll let it slide this one time and let you keep your repo 😉 😄
solar whale
hmm - I'm confused.
west bridge
i think i found something that might help? i tried compiling the repository in the arduino program and it said i was missing core_cm0plus.h
solar whale
Try closing out of the ARDUINO IDE - then try single RESET.
west bridge
same issues
west bridge
i'm still having it turn off and no folders pop up
solar whale
also just to be sure, this sis a TRINKET M0 -- says Trinket M0 across the end opposite the USB
raven canopy
@west bridge I recommend "starting at zero" and following this guide: https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/arduino-ide-setup
after that, then try and fold in the other project.
west bridge
ok !! i'll try that but i just learned it's a trinket 3.3v
so. that probably explains it
solar whale
yup 😉
raven canopy
oh...well, yeah, that would explain it.
west bridge
i'm sorry y'all i thought it was an m0
solar whale
No problem -- had me really scratching my head , though!
raven canopy
no worries, @west bridge.

@lunar cave It's easier to not use the MicroPython plugin as MicroPython does not behave the same way as CircuitPython. If you're looking to have the serial console and REPL available inside PyCharm, I suggest opening a Terminal from within PyCharm, and using the screen command to open a connection to your board. I've never had success with the MicroPython plugin working more than once, without deleting all of my settings and starting over every time.
Hmm if you're on Windows, I'm not sure whether screen will work. I don't use Windows so I don't have specific help for you there, but there are others here who do and may have better suggestions.

putty is the equivalent to screen on windows
idle owl
@lunar cave Yeah, apologies regarding that. I think we need to remove that from the guide as I've had little success with it and it's not mean to work with our boards. It was a good idea at the time, so we included a note about it, but it shouldn't be so blatantly highlighted as to imply that it's a suggested way to work with CircuitPython
tidal kiln
"equivalent".... it's what people generally use for an ssh client on windows

Got my 1x1 SAMD21 board up and running and and half assembled, mainly fiddling with itty bitty dotstars mounted and wired on my micro breakouts. I missed the deadline for the contest but I’m trying to get it finished just to say I did. I might do a revision without the dotstars as a fun general purpose wearable board and will probably inevitably make an M4 version.
I’ll send out my CP-32M4 board once I work with oshpark (Drew?) on my micro usb footprint issue and can make a new footprint for the newer better connector. My other battery powered board will also see another revision to try to lower the BOM cost and adjust some dimensions.
Spent airport time working on my board design tutorial and realized that it probably wants to be a three parter, so I got about half way through the first draft of the first part though many parts will probably be best described in video form so I’ll have to think about doing that as a companion.
In non-programming news I helped move my moms from Arizona to Nevada and saw many tesla chargers on the way.
PS: If anyone has suggestions for accessories to get with a first oscilloscope, please let me know. With any luck I’ll finally be getting a DS-1054Z after squirreling away duckets and shekels for a while now.

One more begginer question, I played a bit with starting example on trinket m0 = rotating colors on rgb led, i removed all unused code, removed print() and finaly started on just power usb, so no COM traffic i guess. and it seem that main loop cad do like those 255 in about a second.. what is a bit slow? I mean do certain operation take a lot time? may be setting values to led or so? I mean i expected it start blinking super fast? Is that because interpreting python code over and over? Is there huge performance difference to arduino style compiled code?

@stuck elbow yea yea i am used to compiled languages and on normal procesors.. so i have no idea yet 😃
tulip sleet
@lunar cave running the interpreted code is slower; we are working on some improvements to the speed in the long run by putting more of it in C. If you are doing rainbow_cycle, you can speed it up just by skipping some of the ranges, and it will still look good:
def rainbow_cycle(delay):
for j in range(0, 255, 8): # Note the 8
for i in range(ring.n):
idx = (i * 256 // ring.n) + j
ring[i] = wheel(idx & 255)
ring.show()
time.sleep(delay)
@lunar cave CP will not be as fast as Arduino. the amount of difference will vary depending on what's being done.
lunar cave
Yea i was just curious on ... rough speed, not particulary on rainbow.. i just used it you know just something to measure..
tulip sleet
also avoid floating point arithmetic if you can: use // instead of /, etc.
lunar cave
but may be it is not that important if most time takes io communication? like lets say db accesse on server ?

I'm losing a track of time a bit) I was discussing some problems with yellow dotstar pulsing on random boards that share a power supply (one 24V powersupply for several Trinkets M0s and each of these M0s has its own stepdown converter). I would like to try to turn off the failsafes and see how it holds up.
OK I need to know if the 2.3.1 firmware has that falesafe already in place. If it does then I've just stumbled upon a bug in the 3.x.x version IMHO.

Hello, could anyone help me with this error? It occurs when I try to play a audio file that is larger than 2mb on an external sd card connected to my ItsyBitsy M4.
Error:
File "adafruit_bus_device/spi_device.py", line 81, in enter
File "adafruit_sdcard.py", line 408, in readblocks
File "adafruit_sdcard.py", line 272, in _block_cmd
File "adafruit_sdcard.py", line 239, in _cmd
File "adafruit_bus_device/spi_device.py", line 81, in enter
RuntimeError: maximum recursion depth exceeded

I tried to change the frequency of the file and changing the audio playback to mono. The sd card reader from adafruit is connected using SPI. I'm still not having any luck with this.

@steep moth what version of circuitpython?
steep moth
I believe it is version 3.0.0
slender iron
that error can happen when you run out of stack space. I'd suggest updating to 3.0.2 first and trying it
steep moth
Okay, I will try that. Thank you.
slender iron
we haven't done a lot of playback from sd so it could be a bug there too
@idle owl new count is 109

ok keen
Are you in the newsletter? and if not do I have time to add a quick and probably mediocre note?
slender iron
no, go ahead. it'll be good!
steep moth
It works, but it is a little choppy. I think that I might have something to do with the frequency of the song playing at 44,100Hz. Anyway, thank you so much for the help!
😀
slender iron
great!
steep moth
Do you have any idea what could cause the audio to be choppy? Or could this just be a bug in the software right now?
steep moth
Is this sample rate controlled in software, or is it caused by the size of the file? Again thank you so much for the help!

RE: Hacktoberfest Labels
Are we free-wheeling assignment, or will it be moderated through Adafolks? If moderated, put me down for roaming GitHub for suggestions/assignment. 😄
idle owl
@raven canopy I can answer that, but it will be a little bit
raven canopy
👍

@solar whale just got an AM2315 to start playing with and possibly write driver for. wired it up and just used AM2320 lib for now. rediscovering some "features" and came across your sleuthing:
https://github.com/adafruit/circuitpython/issues/1053#issuecomment-406790775
did you go any further with that?
steep moth
@slender iron I understand now, thank you so much for the help. This is what I love about Adafruit, the people are so helpful.
slender iron
😃

@tidal kiln haha. those AMxxx features. gotta love 'em.

@slender iron do you feel like we should run make translate on every PR to get the line numbers right in the .po and .pot files, or only run if we know there's been a change/addition/deletion in the translate(...) strings?
slender iron
the latter at least
I don't want to require it for line numbers. People are welcome to though

adabot changes here: https://github.com/adafruit/adabot/pull/17

@tidal kiln nothingbt add beyond what is there. You definitely have to allow for the “wake up”. I have not looked at the am2315 yet. Not as inexpensive as the 2320s to play with.

@raven canopy Ok, so we would love to have the visibility that comes with using the Hacktoberfest label. They have some suggestions regarding which issues to tag, good for beginners, clear scope, etc etc etc. We have a CoC and guidelines identified so we're covered there already. If you're up for it, I would LOVE it if you went through and started labeling things, I trust your judgement on on what makes sense, and if you're unsure, feel free to ping me and we can decide together. It was something I have on my list but wasn't sure where I intended to find the time.
tidal kiln
@solar whale thanks. i'm going to fallback to testing the am2320 and see if that fixes other things...
https://github.com/adafruit/Adafruit_CircuitPython_AM2320/issues/4
i'm thinking the am2315 is just a repackage with the same guts. it definitely behaves the same.
idle owl
I was wondering if that would be the case
solar whale
@tidal kiln let me know if there is anything I can do to help.
raven canopy
@idle owl sounds good. i remember the scope of last year's labels, for the most part. hey, there may be some straglers with "hacktoberfest label removed".. 😆
idle owl
Dinner time! Be back in a bit.

@uncut coral hmmmm. it's been tried...maybe?

interesting gui lib https://github.com/peterhinch/micropython-nano-gui
tidal kiln
@slender iron how could we generate this? not sure how we can insert that delay before the stop
slender iron
¯_(ツ)_/¯
slender iron
I've never seen a delay before a stop
slender iron
lemme look at the samd datasheet
does the sensor hold the clock low?
that could be clock stretching
tidal kiln
unclear from datasheet, but i don't think so. the wording seems to indicate this is what the host should do to wake it up.
slender iron
have you tried it?
tidal kiln
i'm not sure i can
