i think that is right, we removed onewireio on the tiny M0's to make room for other stuff
there is a bitbang impl in the library, but i kind of remember I couldn't get it to work properly

@tulip sleet did you find the "super never reset pin" stuff?
ah static const uint64_t pin_mask_reset_forbidden =
tulip sleet
ah `static const uint64_t pin_mask_reset_forbidden =`
I was forbidding GPIO17 ever, which is not necessary when no PSRAM (but can fix that later)
onyx hinge
I'm thinking that it needs a set of definitions for the PICO (like feather v2), WROOM (feather v1) and WROVER, which will all be slightly different?
tulip sleet
or it could be conditionalized based on the sdkconfig settings (CONFIG_ESP_PSRAM... or whatever)
I would rather not get back into the WROOM vs WROVER module specification. I successfully removed that. It was wrong on a lot of boards
onyx hinge
OK I don't know what to do then. These two screenshots are from the wrover pdf and it seems to show that GPIO6..11 are used for the SPI flash. That's different than the PICO, isn't it?
jaunty juniper
so, how about a big red banner here saying "this is not the pico W" ? 😔
https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython
tulip sleet
@onyx hinge I wonder if turning off PSRAM completely changes something in the generated bootloader or expected partition table such that the partition table is invalid for the uf2? Maybe if we erased completely and loaded the .bin ??
hmm, no I think you were loading the bin anyway, but did you erase completely beforehand?
onyx hinge
no I don't generally do a full erase.
but "make flash" does replace/update the bootloader
it seems clear that the flash WORKS since the code can execute, it's something else spooky
but now I'm working on other thing 🙂

Are there any library standards or designs for things with many many bitflags
the tmc2209 driver has 24 registers and some of them read out pretty complex bitflag sequences

the usual way in C would be to define integer constants for each flag bit, or maybe bitfields in a C structure (less portable because of implementation-specific bit ordering)

Are there any library standards or designs for things with many many bitflags
For CircuitPython, we have the https://github.com/adafruit/Adafruit_CircuitPython_Register library (there's also an SPI version). We use it a lot in our various driver libraries. We wrote a similar thing for Arduino as well

In order to create a new CPy module, written in C/C++ and compiled with CPy API, must I download the entire CIrcuitPython Repo (or fork thereof) and compile it, OR Do i merely use CookieCutter to create the Git Environment (etc) and just build only the module (which would of course require some CPy dependencies. ??? I know its a noobie question, but floating in a sea of info and not sure which direction to swim....
stuck elbow
In order to create a new CPy module, written in C/C++ and compiled with CPy API,...
a C module must be part of the firmware, so you have to compile it into the firmware, so you need the whole repo
hidden rain
Would it be best to fork the repo and then copy or just copy to my local. I do not intend on sumitting the entire fork back, merely the module extension.
stuck elbow
there is currently no way to have a module separate from the rest of the code, right now you would have to make it part of the main code, and make it disabled with a #define by default, and only enable it in the board definitions you want
you can look at how I added the _stage module for example: https://github.com/adafruit/circuitpython/pull/398/files
hidden rain
I think CPy libraries (written in C/C++) are separate, since you can add the ones you want/need...
stuck elbow
they are enabled/disabled with variables in the board definition, but the source code is all in the main repository
hidden rain
So when I add a library to lib, its merely turning on the API?
stuck elbow
no, those are libraries written in python
the ones written in C are always built-in
sometimes a library might have a python part and a C part – like the stage and _stage in the example I linked
hidden rain
I guess that makes sense. The entire object code has to be there or it would require dynamic linking...
OK. So should I fork the entire repo for myself and then copy, or worry about all that another day.
stuck elbow
the workflow is generally: you fork the whole repo, clone it to your computer, make changes, compile, test, etc. then push it back to the forked repo, and make a pull request to the main repository
there might be some changes requested to conform to the structure of the other modules, but generally if it's disabled by default, getting it merged is not a problem
hidden rain
Ok. I read that somewhere. But I read so much my head is swimming with multiple things. Just got the build environment up on Vbox Ubuntu. may have gotten confused. Thanks for the clarification...
Now...on to forking...
stuck elbow
yeah, and it's not helped by the fact that micropython has several ways of doing external C modules
but circuitpython didn't use that

Glad you were around.. I hate waiting for all the regular experts on the weekend....I'll be back ...most likely when I fail to compile the repo

@lone axle in September I will be giving my talk about game development in CircuitPython again, do you have anything you would like me to mention in it?
midnight ember
Aren’t triple quotes a way to comment out large sections of code? Why are they valid there?
ornate breach
python doesn't have multiline comments
You can do multiline comments, there is just a very specific way to do it
rough folio
yeah this says python doesn't have multiline comments lol
rough folio
that's a multiline string optimization
but it's still a multiline string
if you parsed the ast or something you'd get a multiline string
cpython (wisely) just optimizes them away
it does the same thing if you were to just drop a 2 in there
but you wouldn't call 2 a comment
or, for example- ```
a = 2+2 """ the start of my multiline
comment"""
throws a syntax errorwould you do this? no, not really- but it's still not a multiline comment
rough folio
wot
ornate breach
Read the article
rough folio
I did
there is no specific syntax here
all it is is cpython optimizing orphaned strings away
"""x""" alone on an empty line would get optimized away as well
ornate breach
def add_stuff(a, b):
result = a + b
"""
Now we return the result, wee!
Hurray! I'm so excited I can't contain
my joy to just one or two lines!
"""
return result```Example from the article of block comment

>>> def x(y):
x = 2+y

"""abcd"""

2 LOAD_FAST 0 (y)
4 BINARY_ADD

>>> ```notice how the comments are removed
but the multiline string literals are not comments
I can't imagine a scenario in which you couldn't use multiline strings as comments excluding accidentally docstringing but they're still not comments
ornate breach
I mean, people do use them for block comments right wrong or indifferent
rough folio
it _literally_ is
actually as a note this was wrong because
"""

“Python tip: You can use multi-line strings as multi-line comments. Unless used as docstrings, they generate no code! :-)” (Source)
rough folio
I found out recently groovy which is some java fork thing has both multiline strings and a cool syntax-method to handle indents in multiline strings
which are largely a disaster in python
ornate breach
To be fair, Python was a mess for… a long time
rough folio
oh actually textwrap.dedent doesn't have the behavior I thought it did
problem ofc being how
def x():
"""multiline
string"""
is how you have to write it out if you don't want "multiline\n string"
groovy solves this via
"""multiline
|string""".something()```but python has
x = """multiline
string"""
x = textwrap.dedent(x)
yeah I've just taken over the jenkins pipelines at work so I've had to get familiar with it
ornate breach
Eh.. I dislike Jenkins. Jenkinsfiles are not really intuitive
Once you know how to use them, great. Learning them is another story
rough folio
their newish declarative pipelines are relatively akin to the yaml thing everyone else is doing
ornate breach
Yeah, I’m unfortunately familiar lol
rough folio
but it still has some very obtuse syntax and you need to dip into script blocks
and then blue ocean doesn't display a bunch of things correctly and really it's been a whole thing

onyx hinge
@hidden rain https://learn.adafruit.com/extending-circuitpython/inside-the-virtual-machine is a good reference EXCEPT that the style of adding a new module is different & simpler now. It is just a single line at the end of the bindings __init__.c similar to this one: ```c
MP_REGISTER_MODULE(MP_QSTR_zlib, zlib_module, CIRCUITPY_ZLIB);

Good starting point! I think I'll try to create a Fibonacci API, very basic, easy to test. This will ensure I have the process down before moving to the more complicated feature. Thanks!

You would drag wires out of the STEMMA connector on your board, make sure they are, on the opposite end, in the proper order so if a STEMMA connector was present, it would be accurate. Make them disappear under the display part.

I haven't looked at the latest updates, but one "would be cool" that I considered at one time is if you could pass in a quoted wildcard to tio and it would expand the wildcard each time it looked for a device.

@slender iron Exactly, if you see the man page there is an example how to connect using e.g. nc.

This way you can share your tty or use it for interactive scripting etc. Very flexible.

I'm imagining tio circuitpython.local/ws/
(web sockets are weird because they start as http and then onto a websocket specific protocol)
wanton latch
@low sentinel Oh yeah, I'm very happy about the recently added configuration file support. It is so flexible, especially if you have different boards and want custom serial configurations for each. Simple but very useful.
@slender iron My tio command will simply host the tty I/O via websocket protocol on port 1234
Then you can connect any way you want.

using tio to connect to a websocket from a cp device

No no no, sorry. That will never happen. Tio is a serial client, it's sole purpose is to connect to serial devices. From there it can forward I/O to file or network sockets and maybe websocket in the future. For what you want you use a different tool like websocat.
I mean, a tool can do too much 😉

@slender iron where do creation IDs "come from"?

so we get to allocate the numbers however we like? do they need to not collide with USB VID/PIDs that are allocated?

@lone axle what Scott mentioned about pulling dotclockdisplay and putting it down in the ports/Espressif…. Rather than figuring out the tree to make that work, this is one of the hacks I used to “just get it to work” and left this to deal with later. One related example I know of is ParallelDisplay module where a lot of ports raise “NotImplemented”.
Can’t remember if I included this in the ToDo list on the issue.

I've made a note to work on moving it over. I'll look into that one to find the necessary fallback for other ports.

I have my build environment for the rp2040, the Simple 42 template and mymodule/myclass renamed (both fibonacci). From CPy, I would like to call an interface to establish the fibonacci class instance, then call an interface to calculate N values, retrieving the sequence of values. This is merely a dry run to see that I have the process down (prep for ADC-DMA). Any advice on how to augment the template (api) to achieve this goal or otherwise?
tulip sleet
I have my build environment for the rp2040, the Simple 42 template and mymodule/...
not sure what you mean by "augment" in this case. The shared-bindings code creates the instance, and then you're going to implement a method to do the calclulation. That will be in ports/raspberrypi/common-hal/<nameofnewmodule>/<nameofnewclass>.c.
hidden rain
So other than renaming mymodule and myclass in files in shared-module and shared-bindings folders, the real implemetation is in common-hal. OK. So far I built the latest (vanilla) build and tested the UF2 on my Pico. You guys have made things very straight forward....
manic glacierBOT
slender iron
@hidden rain implementation is in shared-module for port-agnostic implementations or common-hal of a particular port
hidden rain
I suppose since I am ultimately creating an ADC-DMA module it might only be available for DMA enabled boards and each may have independent implementations. I'm only going after the RP2040 for now.
Will attempt to keep API generic enough for others.
slender iron
yup, those modules are generally shared-bindings and common-hal then
hidden rain
ok, Ill check back when the compile fails or the API fails... Everything so far is straight forward, but I'm sure I will run into the rough soon enough.
tulip sleet
you could make the routine return some dummy values for now, just to make sure the linkage is working

crimson ferry
Probably answered long ago, but... There is no explicit wifi disconnect(). You can disconnect by using either wifi.radio.enabled = False or wifi.radio.stop_station(). The .enabled property will affect any current Station or AP. start/stop``_station()' and start/stop``_ap()can be used independently of.enabledto change whether a device "mode" is a Station, AP, both, (or none). i.e., Station and AP can be started and stopped when wifi is enabled or disabled, and "mode" will survive an.enable = False. This gives a lot of useful flexibility in adjusting the mode (and various other wifi.radio.` properties), whether or not wifi is active. /cc: @jaunty juniper
onyx hinge
@crimson ferry Thanks. I think the question became moot but I appreciate the detailed answer.
I wanted a way to simulate some of the things that happened to wifi when the interpreter reset, but I worked around the problem with just a few more CP rebuilds than I might have needed otherwise.

"For this board, tap reset and wait for the LED to turn purple, and while the LED is STILL purple, tap reset again. If you wait too long, the board will show up as CIRCUITPY again."

@tulip sleet It doesn't fit on the "Install UF2 Bootloader" page, or the Factory Reset Page. Both use the ROM bootloader. Which does not involve the LED.

I suggested that because the first paragraph (example her on ESP32-S2 Feather) says:
The Adafruit ESP32-S2 Feather ships with a UF2 bootloader which allows the board to show up as FTHRS2BOOT when you double-tap the reset button, and enables you to drag and drop UF2 files to update the firmware.

@idle owl A2 is not a pin that can be used for PWMOut. I tested with CPy 5.0.0, so I'm pretty sure this has always be true. That pin only has one internal timer that can be used, and it can't actually be used for Reasons.

All three pass the initial tests, the only thing I've notice so far is that occasionally when bringing up the file browser page no path is displayed next to the python and no files are listed. Simply refreshing the page has brought up the correct file list and path each time so far. I haven't tested enough for the numbers to really mean anything yet, but it's happened twice on the C3 and once on the S3. In my testing of the C3 so far the networking has been hit or miss, so I'm thinking the file browser may be giving up too early
slender iron
@onyx hinge I'm not sure if I tried it
@wraith crow can you see what happens in the browser's dev tools? I'd be curious if the js fetch is getting an error or empty result

the absolute latest
radiant trench
for that I have to build myself right?
jaunty juniper
it's still in development and there's new fixes all the time
you get it from the site on the "Absolute Newest" S3 link
top one will be the latest build (it's uploaded every time a PR is merged)
radiant trench
Boom! That got it working
onyx hinge
hmph. I had noticed that the gc_alloc took both a flags argument AND a bool for long-lived. I thought maybe putting long-lived in the flags argument would save code size but .. it didn't.
(I figured it'd be able to avoid loading a register with 0 or 1 for every gc_alloc call but either there aren't that many [there aren't that many] or lto is able to optimize it out since it's usually a constant argument)

I can't tell if I'm being daft, but I don't see the default username for the web work flow file manager in the documentation (I set the password)

Now going through the building circuitpython learn guide to get my dev environment up and running, then I should be able to get the CSS modifications I promised a week ago 🙂

@radiant trench I'm at my desk now so can answer any questions too
radiant trench
awesome, I'm just getting the local repo up and running and will do a practice build
did you have any thoughts on how you want it to look and feel? I was thinking of borrowing some basic typography styles from circuitpython.org for consistency?
slender iron
not really. my main concern is that it works offline and without bloating the firmware size too much
(though we could have a second online css to supplement)
the online one will be hard to maintain though because it'll be used with different versions of the files from cp
radiant trench
I'll make the first pass super minimal then. I think it's a good place to start, just improve the typography a little, get the line-lengths under control etc
less for me to mess up too 😄
slender iron
@onyx hinge did you mean to finish https://github.com/adafruit/circuitpython/pull/6608?
radiant trench
I'm following the guide here to get setup to build CP locally... https://learn.adafruit.com/building-circuitpython/build-circuitpython
When I do pre-commit install I get the error zsh: command not found: pre-commit
is there something missing from the guide?
everything else before that seems to have gone ok
(I'm on a Mac running Montery)
slender iron
did you do a pip install before?
slender iron
yup
radiant trench
Yes, I got "Requirement already satisfied" for most of the lines
radiant trench
yes, I don't see it in there anywhere
slender iron
pip install pre-commit
radiant trench
pip3 right?
radiant trench
ha ha, sure happy to do so
I guess I just have to add it to requirements-dev.txt ?
slender iron
yup
radiant trench
is it as simple as? # For pre-commit pyyaml black pre-commit
slender iron
yup, think so

hey guys, quick PR question - to add support for a RTC I ended up needing to add many optional arguments to adafruit_register.i2c_bcd_datetime and adafruit_register.i2c_bcd_alarm - is that something that I should propose as a PR? Or are those classes supposed to stay simple

@slender iron should we bump the mpy-cross-mac build to macos-11? I'm thinking that rather than 12. 12.0 was released 10/2021. 11 was introduced 11/2020.
I have not heard of many people running 10.x (except my father 🙂 ) and the older ones can remain for download

we can see what happens. Sometimes I don't want this - I want to approve but defer the merge build for timing reasons. It's not so much the merge, but the action triggering

I'm still having some trouble getting my build environment working... when I run the pre-commit install stage, I still get the error zsh: command not found: pre-commit (and I ran pip3 install pre-commit first which seems to have gone fine)
radiant trench
ah cool. ok. So on to the next problem 😄
I'm in the directory ports/espressif and I run the command make BOARD=adafruit_feather_esp32s2_tft I get the error CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

@slender iron @onyx hinge FYI, GitHub actions is pretty flaky today. Most job sets have at least a couple of failures that are internal Azure network failures. I found another job that had spent an hour trying to fetch the last little bit of some file, and cancelled that run (it was just a PR merge build).

Is psram slow or is it my idea?
built tinyuf2 & circuitpython from scratch for Waveshare ESP32-S2-Pico
and successfully booted ljinux onto it
but the commands seem oddly slow to start and finish
tulip sleet
certainly slower than on-chip static ram
brazen hatch
like its not a catastrophic delay, but its a good half a second for most external commands
thats a board circuitpy doesnt support, and I will have to pr it when im done
waveshare is kinda weird
they "advertise" circuitpy support, but they provide a uf2 for a completely different board..
tulip sleet
it's not -that- slow, it maybe reading files or something
brazen hatch
it's not -that- slow, it maybe reading files or something
yea, ljinux commands are files, cant keep em all in ram. I need it to work under 120k
but that half a second delay is not present on the pico

@onyx hinge still waiting for your review: https://github.com/adafruit/circuitpython/pull/6608

it's blocking a couple other PRs, so that's why I'm bugging you
could have dan review
onyx hinge
OK, I think I can get it done.
@tulip sleet have you checked whether booting a no-psram build on a has-psram module has the same problem? for devkits I'm only seeing ESP-WROVER-KIT with jtag, but it has psram. in any case, let me know what you pick up and I'll preemptively pick up two too
tulip sleet
OK, I think I can get it done.
i was testing on ESP32 V2 Feather, just now
@onyx hinge https://www.digikey.com/en/products/detail/espressif-systems/ESP-WROVER-KIT-VE/13584249 maybe. also the smaller Saola boards. I have to go, will look later tonight
not saola, thats ESP32-S2
onyx hinge
another distinguishing feature is the embedded FTDI FT2232HL chip - an advanced multi-interface USB bridge. This chip enables to use JTAG for direct debugging of ESP32 through the USB interface without a separate JTAG debugger https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/get-started-wrover-kit-v3.html
I think this is the one to get
https://www.espressif.com/en/products/devkits lists features, and this is one of the only two with JTAG listed. The other is ESP32-LyraTD-MSC which is for audio stuff and it doesn't seem to be via the dual-ftdi solution
tidal kiln
@tulip sleet fyi:
https://github.com/adafruit/Adafruit_CircuitPython_MPL3115A2/pull/22
it was just a silly software thing
onyx hinge
@slender iron I wonder if it would be helpful to add a function that gets a guaranteed-terminated, guaranteed-untruncated value. I think it might read like this but of course with buffer handling in C there's always a great deal of room for embarassing failure: ```c
/* Retrieve the value for a given key, if it fits in the buffer (including a terminating '\0')
*
- Returns: NULL if the key was not found, or the value did not fit (including the terminating '\0')
- Returns: value if the key was found, and its value fit. value is a '\0'-terminated string.
*/
char *dotenv_get_key_terminated(const char *path, const char *key, char *value, mp_int_t value_len) {
mp_int_t actual_len = dotenv_get_key(path, key, value, value_len-1);
if(actual_len == -1) {
return NULL;
}
if(actual_len >= value_len) {
return NULL;
}
value[value_len] = 0;
return value;
}
drat, the direct use of the FAT file access APIs means I can't build dotenv module into the unix port for testing. 😕 @slender iron I guess this is a necessary evil? Does it mean I also couldn't access /sdcard/.env with it if I mount /sdcard?
slender iron
@onyx hinge probably. I need to figure out what api to use. Probably the same reason that mounting an sd card messes up the web workflow
onyx hinge
OK this is not super important, but wanted to report it anyway ^^^

Evening. About ready to build with a test module for RP2040. I have files in shared-bindings subfolder and in ports/raspberrypi/common-hal subfolder. The instructions indicate to add file names to Makefile (SRC_SHARED_MODULE list) and mpconfigport.h (EXTRA_BUILTIN_MODULES). However, these places do not exist, so instructions might be a bit dated. Can not find a consistent example to follow. Please guide...

You don't do that any more. Just add something like this to the bottom of the __init__.c file for your new module:
MP_REGISTER_MODULE(MP_QSTR_busio, busio_module, CIRCUITPY_BUSIO);
ah.. already did that. guess i'm a little over efficient and precautious.
tulip sleet
substitute the name of your module for busio and BUSIO. CIRCUITPY_BUSIO indicates the compile-time enable/disable flag, which is handled in py/circuitpy_mpconfig.mk and py/circuitpy_config.h. Look at other examples there.
put it in alphabetical order

Will do.. very close now. After test module works out, I'll start on the ADC-DMA stuff. Already found lots of good references and some code. Will resume tomorrow .. was up at 5AM ...pushing this thru...Thanks!

This UF2 will erase all flash: https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/circuitpython#flash-resetting-uf2-3083182

Yep, I wound up using the UF2 on raspberrypi.org to reset the flash. Lost a bit of work on my project but shouldn't be too hard to get back. Moral of the story: always make backups. 🙂
