solar whale
off to walk the dog --- good luck all!
marble hornet
enjoy!
onyx hinge
@teal bear that's almost certainly my fault. there's only one clock ๐ that's documentation taken from desktop unix python3's time.clock_gettime_ns which actually does have multiple clocks it can refer to. A PR to remove the text about the non-existing clock specification would be very welcome. Thanks!

@onyx hinge I should modify the Debouncer library?
teal bear
@onyx hinge will do. also.. clicking Edit at the top 404s
thorny jay
I need the lattest version of CP because it use the usb_hid report to tell me about CAPS_LOCK and other... so there is no version with both long integer and this.
onyx hinge
@half sedge If you follow what I am suggesting, I think a change which does similar to Adafruit_CircuitPython_LED_Animation with the monotonic_ms function should be acceptable. Careful, I updated the link because it was to the wrong fork. ms not ns, because working in milliseconds is a pretty good compromise that gets accuracy but doesn't overflow for ~12 days
It's still not perfect, because I think as written it will give a Python exception at 12.4 days for platforms without longs
thorny jay
There are ways to deal with warp arround. When the value goes from very high to negative or near zero, it is possible to detect and deal with that.
I feel like not all consequence of removing long int have been identified.
onyx hinge
@teal bear hmmm I don't know what to do about that link 404'ing, can you file an issue so we can at least remember it happens? It has to do with the way we generate our documentation in several steps, and I guess that works differently than readthedocs needs
teal bear
@onyx hinge https://github.com/adafruit/circuitpython/blob/main/shared-bindings/time/__init__.c#L218 what should the doc be?
onyx hinge
@teal bear desktop python3 documents it as follows: ```Help on built-in function monotonic_ns in time:
time.monotonic_ns = monotonic_ns(...)
monotonic_ns() -> int
Monotonic clock, cannot go backward, as nanoseconds.
it's very terse in the pydoc and there's probably a longer description in the online manual
teal bear
cannot go backward - so it doesn't wrap, and "int" means forever?
onyx hinge
"int" means the values are whole numbers (integers)
thorny jay
The code of Debouncer actually check if time.monotonic_ns is present: https://github.com/adafruit/Adafruit_CircuitPython_Debouncer/blob/master/adafruit_debouncer.py#L67
It is present but not working:
import time
hasattr(time, "monotonic_ns")
True
time.monotonic_ns()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NotImplementedError: No long integer support
onyx hinge
Again you can check out the LED library, it also checks whether calling the function results in NotImplemented.
I believe this workaround is as complete as it can be
I agree with what you say about the ability of properly written code to deal with clock wraparounds. That's why I straw-proposed microcontroller.montonic_ms_wrapped earlier in this discussion. This is something where @slender iron also has opinions, so I'd recommend bringing your best proposal to an in-the-weeds sometime soon. Something that is (A) not placed in a desktop Python module like time -- microcontroller or rtc are the only places I can think of, (B) can work with/without longs, (C) does not have precision problems due to using float and (D) implementing in blinka is likely to be easy seem like a good set of considerations to meet. Showing that it's needed by 2+ libraries (LED animations & debounce) and showing how it could be used would be very good information to bring too.
thorny jay
That's above my head... I just want to use a library that is now broken. I understand most of it, but I don't have a solution to propose. I'll fill an issue and try to apply a check for NotImplemented... that might solve my problem, but not the underlying problem.
Thanks
onyx hinge
I don't believe it has to be above your head, but I understand if you don't care to engage at that level.
thorny jay
I can raise the question "in the weed" and let you discuss between Pythonistas. ๐ For me, the best solution could be to restore long integer (if it's possible). But it start to be sad to work on M0, things seems to fall apart loosing feature left and right.
teal bear
@onyx hinge int and "cannot go backward" together imply it will never wrap - is this correct?
onyx hinge
It is not possible to satisfy all interests, even more so on the more resource constrainted boards. As always, you have the opportunity to use a custom build or an older version, if it better satisfies your particular needs.
@teal bear right, it increases forever, it never goes back to 0
teal bear
sweet.
onyx hinge
And yes we never foresee all the consequences of our decisions, it's impossible. We can always work to better foresee consequences, but we know each time we compromise that someone will be impacted more heavily by the decision than another.

"Return the current time in seconds since since Jan 1, 1970." https://circuitpython.readthedocs.io/en/latest/shared-bindings/time/#time.time
onyx hinge
I think circuitpython's time.time uses a different epoch date
also most boards without a battery-backed RTC have time.time referenced to "no particular time, maybe the moment that power was applied or reset was pressed"
teal bear
yeah. that's really what I was wondering about
onyx hinge
The docs there could use some love
OverflowError: timestamp out of range for platform time_t
>>> time.localtime(2**30)
struct_time(tm_year=2004, tm_mon=1, tm_mday=10, tm_hour=13, tm_min=37, tm_sec=4, tm_wday=5, tm_yday=10, tm_isdst=-1)
maybe the docs are accurate (for time.localtime, on boards with long ints anyway)
teal bear
time_ttime.localtime(946684800) is 1/1/2000 ... 946684800-1 is OverflowError: timestamp out of range for platform
time.localtime(2147483647) 1/19/2038 struct_time(tm_year=2038, tm_mon=1, tm_mday=19, tm_hour=3, tm_min=14, tm_sec=7, tm_wday=1, tm_yday=19, tm_isdst=-1)
time.localtime(2147483647+1) OverflowError: overflow converting long int to machine word
2147483647 - 946684800 = 1200798847 ... which is ... odd.
teal bear
#define EPOCH1970_EPOCH2000_DIFF_SECS 946684800 - this is the missing chunk: 946684800 + 1200798847 == 2**31-1

tulip sleet
@onyx hinge That is weird: I'm looking for a setting that might have gotten changed accidentally.
@onyx hinge It's because it's a PR against master instead of main. Maybe Scott changed the minimum number as an alert that it was against the wrong branch.
teal bear
Is main the new thing?
tulip sleet
yes
it's been true for a couple of months at least
Maybe we should just delete the master branch now
onyx hinge
@tulip sleet do you have the necessary permission to change which branch that PR points at? I know tannewt was able to do it for some PRs when doing the master->main transition
but I don't see a UI element for it, I could be missing it, I could have the details wrong, or it could be outside my permissions
tulip sleet
I don't think that's possible; it just needs to be resubmitted as a PR against main. @teal bear could you rework? Thanks.
onyx hinge
oh there it is
tulip sleet
how did you do that magic?
onyx hinge
click "edit" by the PR's title and then "master" becomes a clickable box. I selected "main"
tulip sleet
great! thanks
teal bear
do I need to do anything, or is it done?
onyx hinge
Looks like it requires changing -- there are "conflicts"
tulip sleet
Jeff fixed it
onyx hinge
probably better to start a fresh branch and just make the change again. I think basically we reformatted all our docs since the old revision you based your PR on.
teal bear
got it.
onyx hinge
Thank you!
tulip sleet
actually, probably not safe to delete the branch in case want to go back in time. It would be nice to lock it down but it doesn't appear possible.
onyx hinge
replacing branch master with a tag master is suggested by some sources to in some sense keep it, but prevent being able to create PRs
however, I kinda suspect changing a branch to a tag may confuse existing clones when they pull again
onyx hinge

*value = hri_sdhc_read_BDPR_reg(hw);

stuck elbow
Yeah, const makes no sense in repl
onyx hinge
I sometimes like to paste things from .py files into the repl, and usually it's just fine
probably if I'd done those lines together in the "paste" repl and they were evaluated together it would have worked? Not sure
solar whale
@onyx hinge its the "_" that makes it not defined -- x = const(123) will define x

I have a new bluetooth board (custom hardware with and nrf52840) that is crashing whenever
import adafruit_ble
is run. If i remember correctly this can be caused by the lack of a soft device. I'm trying to use a jlink to upload the flash and sd but it seems to not work.
solar whale
@marble hornet IIRC you should flash the sd first, before the firmware. just in case that helps
but that was from a long time ago... may have changed
when loading the bootlaoader I did make BOARD=feather_nrf52840_express erase make BOARD=feather_nrf52840_express sd make BOARD=feather_nrf52840_express flash
marble hornet
okay, i'll give that a try. i have been doing that but typing out the BOARD parameter every time
solar whale
yes you need that -- sorry
onyx hinge
To flash SoftDevice (and chip erase):
make BOARD=feather_nrf52840_express sd
The Adafruit_nRF52_Bootloader's readme says this
marble hornet
okay, i just re-tried those three steps and it it still crashing. it seems like the core goes of the end of the world...(?) after the import the device just hangs. the screen session does not disconnect and the device does not response at all. only hard-reseting it helps
any suggestions?
solar whale
sorry -- you are way beyond my level of experience with it.
marble hornet
okay, thank you. I think i'm in a similar spot, do you know who would have some more experience with this?
slate scroll
@marble hornet maybe the flash operation is overwriting your sd - fiddle with the commands that the makefile executes
if does nrfjprog --erase or something like that maybe there's your culprit
also I THINK that instead of make BOARD=feather_nrf52840_express flash you need make BOARD=feather_nrf52840_express SD=<sd_version> flash
manic glacierBOT
solar whale
The SD options are available when flashing the CP build, but not when flashing the bootloader https://github.com/adafruit/Adafruit_nRF52_Bootloader/blob/master/Makefile#L412 at least I don't see it.
marble hornet
@slate scroll i gave a look at the flash rule and it does not Seem to have sd erasure in it. and i'll give the SD=<...> flash a try.
slate scroll
nah, @solar whale is right
marble hornet
huh?
slate scroll
try flashing the circuitpython hex by hand, without any erase flags
sd won't make a change during normal flash
do you have a debugger attached? maybe you can see if there's anything on the sd address
marble hornet
i do, is that 0x0 thorugh 0x25000?
slate scroll
through 0x26000
check the first 100 bytes
and do a hexdump of the sd as well - just to be on the safe side
but something tells me that's not it - every time I need to dig this deep with these mcus something else (and very simple) is wrong
also since you have a debugger, where does circuitpy crash?
marble hornet
will do. (am doing). i'm not super comfortable with using the debugger (i mostly have used if for flashing bootloader). i'm a jlink connected to a mac. may take a moment, i have to read the man pages
slate scroll
duh, I feel you, I'm not comfortable around debuggers either
keep in mind VSCode has amazing debugging experience, even for me. since you're getting your hands dirty, take a day to set it up properly
(and I can't stress enough that you got to try VSCode if you haven't)
slate scroll
yy
marble hornet
okay, i've dumped 0x0 -> 0x26001
want to see? it is non zero information
**as in upload ?
slate scroll
I don't have the SD handy, so just do a hexdump on the SD (the one you downloaded from adafruit) and check if the first bytes are the same with your dump
marble hornet
the one i downloaded from adafruit?
which one are you referring to?
ah
they are only different by a few bytes at the end. I dumped off of a feather 840 stock from adafruit (never programmed) and the custom board
$cmp dump-feathersd.hex dump-watchsd.hex
$dump-feathersd.hex dump-watchsd.hex differ: char 155649, line 728
perf, I don't think you have a problem with the SD then
I'd start debugging (crying as well)
marble hornet
i regret putting the swd pin on pogo pads ๐ญ
I'll just solder them, i haven't debugged before with a jlink, any guides, recourses, advice you would have found useful going it?
ionic elk
I'm trying to get readthedocs going for my community bundle. How do I get Sphinx to not freak out about the use of const in my library?
onyx hinge
@ionic elk I'm not sure but we could look together at a module that uses const in the bundle. I spotted adafruit_fram.
tulip sleet
it's a mock import thing; just double-checking
onyx hinge
it has from micropython import const then later _MAX_SIZE_I2C = const(32768)
it does not have the mock import library enabled as far as I can see: ```# Uncomment the below if you use native CircuitPython modules such as
digitalio, micropython and busio. List the modules you use. Without it, the
autodoc module docs will fail to generate with a warning.
autodoc_mock_imports = ["digitalio", "busio", "micropython"]
actually not, but it's in blinka, so that covers it
is adafruit-blinka in your requirements.txt?
ionic elk
what is the mock import library?
no
I'm just following Scott's tutorial https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/sharing-our-docs-on-readthedocs
tulip sleet
do that, that should fix it
ionic elk
adding adafruit blinka? But I'm not a blinka library
tulip sleet
could it be used under blinka?
onyx hinge
Are you getting this message locally or from ci? If locally, you may/probably need to install blinka yourself.
tulip sleet
pip3
do not do sudo pip3
on windows, just pip
depending on how python is set up, pip might install for python2, not python3
onyx hinge
the pakage name is adafruit-blinka so that's what you'd put on the pip commandline
slate scroll
i regret putting the swd pin on pogo pads ๐ญ
@marble hornet yea, always break them out properly (breadboard friendly)
ionic elk
Ok, I installed adafruit-blinka, but it still fails
is this even worth it? Like, the docs are up on readthedocs, the library works, is it actually required to do this?
I don't really even care about setting up github actions, is it required to be on the community bundle?
tulip sleet
could you show the error?
tulip sleet
could you push this to a repo so I could look at the whole thing and try it?
ionic elk
tulip sleet
btw, if you enclose a link in < >'s, it will not add the attachment in discord
tulip sleet
I don't see a from micropython import const in the code
ionic elk
is that actually required?
tulip sleet
it should be, but it seems not to be
ionic elk
It doesn't seem to need it in testing
tulip sleet
anyway, add that
ionic elk
nice, that solved it
what about the image thing? If I want to add images, do I need to copy them into the docs folder? or something
tulip sleet
look at the adafruit_circuitplayground for how to do that; i know that library has them to show where the pins are on the board
ionic elk
ok. Thanks for your help, dan!
tulip sleet
np, yw!
ionic elk
I think that guide could use an update, though. The github actions part is especially confusing, it doesn't really relate to what you see on Github at all. Might have changed as an update?
There's this whole select workflows thing
Anyway, heading out to lunch, again, appreciate the help!
tulip sleet
if you can make simple updates, go ahead, else just clikc on the feedback link to at least note it. tnx
ionic elk
ok, will do when I figure it out
marble hornet
okay, I think it is a hw issue. i just flashed the custom firmware to an adafruit nrf52840 and it works. seems like nrf52840 cannot have a functioning (uf2) bootloader without the sd.
tulip sleet
@marble hornet SD depedency was removed as of https://github.com/adafruit/Adafruit_nRF52_Bootloader/pull/128
But there has not been a release since then
@onyx hinge I am not bothering with #3404 because it's part of #3405, right?
onyx hinge
@tulip sleet yes, I think so, unless #3405 is going to stall -- I (just) marked #3405 ready for review since it passed CI without further problems.
tulip sleet
ah, great, I will re-review (I did an informal review)
onyx hinge
huh https://www.githubstatus.com/ has lost the time series charts (and says everything is fine; which is odd because a bunch of github actions jobs seem to be stalled / not starting)
ionic elk
@tulip sleet so, does Adafruit have a set of git actions that they've designed and use? Are those available for public use?
I'm getting the vibe that I'm simply missing the actual workflows I need. Presumably I need to copy them from somewhere?
onyx hinge
cookie-cutter gives you what we use, plus or minus modifications made in individual repos.
https://github.com/jepler/Jepler_CircuitPython_udecimal/ is something I recently cookie-cut (my first time) so you can also see the history of what I had to change post-cutting
ionic elk
you mean cookie cutter is supposed to install git workflows?
@onyx hinge
it didn't create anything for me. I don't even have a .github directory
maybe my cookiecutter version is old?
ionic elk
Whew. Got it in. Thanks for the reference material @onyx hinge

Hello guys, I need your help. I am using the Seeeduino Xiao and I have installed the latest CircuitPython on it. The problem is that the displayio module is not available for this board. Why is this? How can I use the board with a display if the displayio module is not installed?
onyx hinge
@wispy badger The Xiao's M0 microcontroller doesn't have a lot of resources, so not all the modules fit in the flash storage available. You can check out the page in our documentation called "Support Matrix" or the built-in help() for an accurate list.
@ionic elk remember how months ago you asked me to look into whether the RGBMatrix worked right on STM for me? welp.
onyx hinge
@tulip sleet I had wondered about that, good sleuthing about where the binary size growth comes from.
ionic elk
@onyx hinge yeah looks a little stretched. That's on my bugfix list after I get these ESP32 and SPI things taken care of
onyx hinge
I'd have called it ghosting, I guess
ionic elk
is it possible to include DisplayIO on a SAMD21 by cutting other modules?
onyx hinge
I know there's at least one M0 Express board with displayio but I don't know about non-Express boards.
@ionic elk on the bright side, https://oshpark.com/shared_projects/ahoBju6X featherwing works
ionic elk
Nice
wispy badger
@onyx hinge Thanks for the reply. I now get it. The FLASH storage of the board is not enough to fit all the modules. Boards with SAMD21 CPUs that include the displayio module use an external FLASH storage as well. Like the Serpente board -> https://www.tindie.com/products/arturo182/serpente-a-tiny-circuitpython-prototyping-board/

@silver tapir I was looking at using the rpi3
silver tapir
I started compiling the micropython port for the pi, but haven't tested yet.
ionic elk
@onyx hinge the beefiest of issues, so thorough
slender iron
pi3 only has one usb peripheral though

A set of CircuitPython programmable nsec and msec timers would be handy.

is it your goal to make it micropython compatible?

I was really surprised esp32s2 went to Main so fast...

If you don't know it is hardware and that was not build for that hardware, you discover when it is too late.

CIRCUITPY_DIGITALIO = 3/5 # 60% supported

The worth is if someone acquire a board for specific use, and discover it can not do that.

If you have many board, you just switch to another feather...

Most Adafruit board have an LED ...

nrf52840 I believe
idle wharf
@thorny jay I find it hard to understand the capabilities between any two boards on the store, but that's not a CP issue.
silver tapir
And, is there a way on software to call a deep sleep mode yet in cpy?
thorny jay
A buyer guide could help to say based on your needs what board is recommended.
What do you need? BLE? WiFi? QT? Screen? Form factor? ...

esp32s2 comes with ULP (Ultra Low Power) coprocessor

@ionic elk Some nice tools for this are either the ลณCurrent or the CurrentRanger. (andreas spiess has showed a bit of this in ytb)
@analog bridge The idf docs says that it is not working yet.

@analog bridge You can only run a bit of riscv C code when it's available.

@silver tapir which IDF features link are you looking at ? the last one I looked at was out of date
thorny jay
Andreas really was showing what it really mean to be low power...
silver tapir
@idle wharf How to use the ULP riscv core. When I say it, it just say "not yet..."
I'm actually learning how scott did the spram on the esp32s2, because I want to learn how to implement low power on the riscv core.

I do have a question but outside the meeting. In one of our talks, the owner of Electric Cats was talking about how to add cpy to your own boards. He had this question, so I relay it here.
How it the process for getting a usb PID for a circuitpython board? And what would be their limitations if any?
slender iron
since they are a maker company making multiple boards they should consider purchasing a USB VID for themselves
silver tapir
I was thinking of talking about this, but for the rest of us, the ones we don't have companies with multiple boards.
lucid solar
@slender iron I'm working on the F1 port, it gets stuck in tud_msc_test_unit_ready_cb. Do you know how that works?
onyx hinge
silver tapir
But I agree that for a company they should get their own.
slender iron
for makers who aren't selling their stuff we can gift PIDs with the adafruit VID
silver tapir
Ah ok, so that would be the limitation. If I plan on getting 50 boards on tindie, then I should invest in getting my own.
slender iron
@lucid solar not really sure what the issue would be
@silver tapir 50 different board designs then yes
silver tapir
But for like a badge, or demo project, etc, their fine. And how would one request a PID?
I meant 50 board of a single design.
marble hornet
a circuitpython based ammeter would be a great edition to the circuitpython ecosystem. since the profiler and profiled would be in cp. and hopefully bring the price down.
I don't have the expertise or time to develop the expertise to make a product like that but thought the idea was worth putting out there.
slender iron
for 50 of a single board we could donate a PID

mp_vfs_mount_t* current_mount = MP_STATE_VM(vfs_mount_table);

is that mount table set somewhere else? so it probably means the flash isn't being setup right?

@slender iron (or anyone else) I have 192kb for FLASH_FIRMWARE, that doesn't seem to be enough. It already feels like it's a minimal build, but do you know of something that will shrink it even further?

can you link me to a diff of what you have?
@slender iron was this to me?

there is also CIRCUITPY_FULL_BUILD that you should set to 0
the firmware.elf.map file is a good way to see what is included still
lucid solar
Yeah, I just don't know what is needed or not...
slender iron
you should be able to turn everything off to start
lucid solar
But that shrunk it quite a lot...~7k left to remove
but I can get that by moving around the 'partitions'

make sure you build with -Os and --gc-sections
the SAMD21 builds also have lto enabled
not sure STM is setup for it

-O2 (that's ok right?)

@tulip sleet thank you, i'll pick one up on my next order. ..
do you have any tips for debugging _bleio? the watches crash on every import (except for one of them, which always times out on connections) and there definitely is an sd @ 0x0
onyx hinge
aha the LED controller on the makerdiary keyboard is IS31FL3733A, I think.
hybrid scarab
Crumbs, had the day off with my toddler and totally forgot it was Monday!
onyx hinge
@hybrid scarab sounds like a good use of your time!
hmm maybe there's no IS31FL3733A support in CircuitPython yet at all !?
hybrid scarab
True, god knows I spend too much time working
Trying to remember if I've written any code for IS31FL3733A ๐
Ah- no- IS31FL3730
onyx hinge
and there's support for 3731 as well
hybrid scarab
Oooh 12x16

In this case there are 61(?) RGB LEDs, it's a keyboard backlight

Math checks out
hybrid scarab
Mapping the darn LEDs is the tricky part
stuck elbow
hybrid scarab
I wrote a - bad - Python library for the IS31FL3730 about 5 years ago
tulip sleet
@marble hornet I haven't seen that kind of crashing before. Your SD version should be 6.1.1, not 7.0.x, which is a 1k larger in size internally
this is a 52840, right?
marble hornet
ah, okay. let me see if I can find how to check that. when the sd is being flashed it erases 0 -> 0x26000 (iirc)
and yes!
tulip sleet
that is right, 7.0.1 goes to 0x27000
marble hornet
ah, and (asking explicitly to be sure) that version does not work w/ cp?
tulip sleet
the latest version of the nrf52 UF2 bootloader (not released yet, I think) will report the SD version in INFO_UF2.TXT
someone has an nRF52833 board def that (must) use 7.0.1, and that seems to be working
it think it is pretty much upward compatible
marble hornet
I'm building from master. looks like it is the right version.
slender iron
you want to pull from main now
tulip sleet
i think the uf2 bootloader is till using master, but circuitpython should be from main
thorny jay
I wrote a - bad - Python library for the IS31FL3730 about 5 years ago
@hybrid scarab I adapted an existing CP driver to support the Led Shim and Scroll pHAT HD.

checking the repo agrees about main vs master,

@thorny jay for the best ๐
tulip sleet
if there is no SD present, it will note that too
thorny jay
Whoever made the mapping of the Led Shim... need to give me an explanation! LadyAda did not want a big table, so I made if/then test and math to make the mapping.
marble hornet
that's really cool! All six of the TG-Watch02B boards have 6.1.1 installed ; I'd love some guidance on how to proceed with an issue like this? if you wouldn't mind pointing me in the right direction or if you have some time (at some point) and wouldn't mind helping dig a bit deeper , either would be greatly appreciated.

I wonder if we should have maintainers listed in board defs
so we know who to ping when someone needs support on a board
ionic elk
maybe port level?
slender iron
perhaps port level but I'm more worried about simpler board-level issues
ionic elk
I'm just a little concerned about the implication of associating circuitpython maintainers with specific 3rd party products
ionic elk
Or would we be linking the people who actually submit board PRs?
marble hornet
The only edge case I see for that is if the person who submitted the pr is the person who made the board.
slender iron
@ionic elk right, the maintainers of third-party boards wouldn't be us
I think an empty maintainer list is ok for third-party boards. at least then we have something to point to
ionic elk
I should note that I've seen a lot more board-specific support tickets in the forums than on github.
ionic elk
So you mean this mostly as an Adafruit product support thing? Less of a link-board-creators deal
marble hornet
if the third part vendor has support forums couldn't you link to those? like makediary's https://community.makerdiary.com/
ionic elk
Would probably want to verify that they were the ones who submitted the board def first, of course
slender iron
@ionic elk @marble hornet Exactly, most companies have support forums. I'm kinda ok pointing folks there even if they didn't add support because they should tell the board maker they want circuitpython support. ๐
@onyx hinge I swapped one issue from 6.0.0 to 6.x.x. I don't want to block 6.0.0 on esp being stable
(which is why I want us to explain stability of each port)

@slender iron seems reasonable
marble hornet
agreed
ionic elk
Ach, how do I solve Warning, treated as error: /home/runner/work/circuitpython/circuitpython/ports/esp32s2/README.md:document isn't included in any toctree again? I'm certain I've done it before but I don't remember the file I gotta edit
slender iron
you need to add it to another table of contents
otherwise no one will be able to reach the doc
I think it's in docs/supported_ports or something
ionic elk
Ahh, gotcha.

How to enable WebREPL over BLE UART for NRF52 Circuitpython? The impression I have from documentation I found is that I need a custom build of Circuitpython. Is this available somewhere or do I build it?

@slender iron thanks for letting me know about switching issue milestone -- in that case I didn't have a strong opinion, I just wanted to get the "no milestone" count down

totally, thanks for setting it
I just want to push us to stable faster than the esp32s2 will let us
lots of good stuff the other ports would already benefit from
hearty forge
Which repo/branch is the "best" to start from for the esp32s2? Adafruit/circuitpython main? tannewt's wifi branch?
idle wharf
Adafruit/circuitpython main is good2go, native_wifi was merged
Now if you want something specific not yet done... might be in Tannewt's might be in someone else's fork...

Thanks @idle wharf ! Looking to make a simple l293d driver library, and then maybe try to port the the rotary encoder library.
idle wharf
Might be in your fork ๐
hearty forge
@idle wharf - Oh! I'm completely new to the CP source- can you give me a pointer to where it might live; I'm blindly cding around ports\esp32s2 ๐
hearty forge
@idle wharf - sorry, was re-reading readthedocs + github (FYI rotaryio page readthedocs page has a broken github link)
I'm wanting to be able to setup rotary encoders; as it's not on the suport matrix for the esp32s2 I assumed there's some work to be done. Just found the C code in shared-bindings... does everything in shared-bindings "just work"??? I'd assumed there's some work to be done & a "build it" flag to be flipped in the makefile.
idle wharf
I'm not a contributor to the C code, so I'll have to let someone give you a definitive answer, but i think if you look for where it exists in another port (like nrf) then I think you'll see what you're looking for. I'm actually trying to see if I can figure out RTC so if you figure out, let me know
hearty forge
Thanks @idle wharf - nrf looks to be an excellent suggestion for a reference to look at. And I quickly looked at the RTC and found this issue (https://github.com/adafruit/circuitpython/issues/2958) which reading through it gives me some more ideas at least of the moving pieces. Nothing like jumping in the middle and not knowing much about any of the directions ๐
@idle wharf what's not working for you with RTC? From that issue it looks to be working???
idle wharf
The specific RTC module is needed for some other libraries (mini mqtt )
So the common-hal/rtc needs to added. I might be able to figure out just from patten matching what is going on the other ports. (I donโt know C) but if not, thereโs an open issue on it https://github.com/adafruit/circuitpython/issues/3321

Hardware safety question for esp32s2 saola - I'm got CP flashed via the built in usb socket. Next step is to add a socket for the built in usb. If I'm connecting to the same PC is it ok to have both sockets connected at the same time? Or should I leave the +5V from the breakout socket disconnected from the 5V (Vin?!) pin on the Saola? And if both USB sockets are wired up (ie usb V+ from breakout is connected to 5V pin on Saola) should a PC only be connected to one or the other?
slender iron
for rotaryio you'll want to enable CIRCUITPY_ROTARYIO in mpconfigport and then add an implementation in ports/esp32s2/common-hal/rotaryio
@hearty forge I usually connect both
hearty forge
Thanks @slender iron ! Re the usb cables- there's "what you can get away with", and "what you should tell students/beginners..." Like current limiting resistors for LEDs (ie short term/low risk projects- risk it. For a medical device... don't ๐ ) Do you know which category plugging both in falls?

I've been doing it since I started working on it. both cables come from the same hub
I make no promises

@slender iron - I'm 3-4 days away from a replacement + $100 minimum order... and I plan to sell/lend these to kids for minimum cost to make it as accessible as I can, so longevity is important to me... and my "save a penny" up bringing ๐คฃ
slender iron
@hearty forge they are saola's? you'll be better off waiting for a better board then
hearty forge
@idle wharf I'm probably in a similar skill bracket, but mqtt is on my list of wanted features. I'll ping you when I get that far- if it's not already working, maybe we can figure it out ๐
@slender iron don't disagree, but I think/hope it'll be good enough to start with - ie learn, build just enough code, build some examples, do some trial runs, and see if there is some local interest. I've got a few spare- but I don't want to fry them as quickly as the first set of trinkets I got... accidentally got the 3.3V version ๐คฆโโ๏ธ

Last question for a couple of days- is the socket code at a point where you can write a basic tcp echo server?
slender iron
@hearty forge no, I only did send and recv, not bind or accept
hearty forge
@slender iron - I think that would be enough to test ideas in a "backwards" sense. Really appreciate the answers; I think I have a roadmap for my project now, and a couple of places I might be able to help the project (flesh out some missing bits) because you and the team have done an orbit or two, providing some examples/scaffold for less experienced folk to start from. Super cool what you've all done!
slender iron
thanks!
hearty forge
Do you happen to have any test/example code of where you left it?
slender iron
bind and accept?
I didn't start it
though they are commented out in the shared-bindings code I inherited from micropython's socket
hearty forge
No- the send and recv- I'm very rusty; any memory-kicks are very helpful ๐
hearty forge
Doh- I was just reading over readthedocs & missed that- also was looking at the shared bindings. Think it's time to take a break. Brain is full!

Version 3, this one is pretty much a flat Planck, since I added two more columns of keys. I'm happy with it and I think I'm going to keep using it.
I still have the previous verson, but with RGB LEDs to assemble
onyx hinge
I think I need a proper plate before this'll be usable. My first experience with keyswitch sockets hasn't been going well, and my attempt at a 3d printed plate didn't "fix" it. not flat or rigid enough, it keeps pulling some keys out of contact. but this isn't a channel about keebs so I'll stop there.

ooh I have received my own message in loopback mode on CANbus with sam e54
ornate breach
oh nice! ๐
I was going to ask you about how the CAN bus development was going @onyx hinge
My team is interested in using CAN bus as an interface for our VLC system
ionic elk
@hearty forge re: usb, can't you just leave the USB breakout cable power off? That's what I do. I just have power coming in over the UART-USB debug cable and the USB I just leave the power unplugged and it works fine
onyx hinge
however when NOT in loopback mode, I don't receive my own messages or other messages on the bus
@ornate breach basic functionality is not yet ready for a pull request .. hopefully soon, then we can see what else is needed for it to be useful.
ornate breach
๐ sounds good, it'll be a few months before we are ready to even start implementing CAN
onyx hinge
what is a VLC system in this case?
slender iron
@onyx hinge I got my plate from lasergist
onyx hinge
hm the transmit and receive programs both start to fail when I set non-loopback mode
I think this register's state is probably relevant: ACT: SYNC Node is synchronizing on CAN communication - Activity -- it sticks in SYNC when not loopback, but gets to IDLE when loopback
๐ฎ
onyx hinge
With "loopback", it's a bit of a misnomer. It can be, and is, received by other devices on the bus.
slender iron
oh, weird
onyx hinge
So it seems like clocks are okay, my bits are all going at the right rate
Yeah I'll look again after food, and go back to the asf4 complete program that I think worked but I'm loopback mode

thorny jay
Hi @onyx hinge , I know I am late for the party, but I just watched the PythonDay video about sdioio. What I did not catch from the video or quick read from the guide is if PyPortal is properly wired for sdioio or only for sdcardio.
I get that the PyGamer is sdcardio and STM32 is sdioio. But do you have a table that say which is sdioio compatible?

Hmm @thorny jay :) did you have any luck using Gamepad on Commander?- I can't get it to work reliably in 6.0.0-alpha.3 but it did work OK in a self compiled 6.3.1 back when I submitted the patch to add it.
@copper crescent It was unsatisfactory, but my first use of it, so I could not tell if it was me or a problem.

@thorny jay yeah, I'm seeing lots of missing button presses too
thorny jay
Should write a very simple test code that only does unitary test to confirm the feeling. An run on another hardware with buttons... but not sure what I have that will not require breadboarding or worse.
Not sure about the internals of gamepad implementation. But with long int removed from M0 it could be affected...

That was discussed in the weed in last meeting 25 hours ago.

@copper crescent Maybe I can try on uGame ... it has buttons, don't you have one too?

@solar whale the new requests changes parsing to be byte by byte. I think its slower but it'll use less memory
solar whale
patience is a virtue
slender iron
I suspect there is a middle ground we could do to grab 32 bytes at a time or something

@thorny jay no, I've dug out an M0 feather so I'll give it a go on that
slender iron
to minimize overhead and memory

Maybe try with the first build after your change was accepted. All build are on S3, so you can check it was working and got broken...

@stuck elbow what USB PIDs do you use on your boards?
thorny jay
Did you get my report that commander reboot on SDcard insertion? Your support page did crash when I submitted all the details and I lost the detail output.
copper crescent
@thorny jay not a problem was just wondering if you had it working but it looks like it's OK on the Feather M0 Express with 5.3.1 but missing presses with 6.0.0-alpha.3 using the example code so it might not be all me ;)
stuck elbow
@slender iron firmware-wise it's fluff m0
that's what I needed it for - to have a board that has all the pins but just naked samd21

@thorny jay Hmm no I didn't, feel free to email/msg details when/if convenient
slender iron
@stuck elbow I'm trying to sort out CP USB PIDS and it looks like pewpew10 shares with gemma and ugame10 shares with the trinket
stuck elbow
that's possible, they were made before I had my own PID
@slender iron if Adafruit could assign some of its PIDs, I see no problem with that, should I go the formal path with this through the bug tracker?
slender iron
I can do it. I just want to know what you are using now
stuck elbow
otherwise I can try getting some more from OpenMoko
slender iron
/ what you need
stuck elbow
pewpew m4 uses my openmoko pid, and fluff m0 got pid from adafruit, otherwise I don't have any more
so it would be nice to assign separate pids for pewpew10 and ugame, if possible
I don't think I have any more CP boards officially published
the keyboards are for my own use so far, and I still didn't finish the robots
slender iron
kk will update pewpew and ugame
what is the id for fluff? I don't see it in our file
stuck elbow

PID 0x80B0 # circuitpython
except I don't have an arduino board definition
slender iron
kk, do you expect to have one? or should we use it for one of your other boards?
thorny jay
@stuck elbow I believe you were behind the Gamepad library? Did you recently tested Gamepad code (the pin version)? Because we have a problem on Commander 8086 where it was recently added.
slender iron
@stuck elbow ugame will be 0x80AF and pewpew10 will be 0x80D5

@slender iron thanks
@thorny jay I didn't test it properly, but I did try 6.x with pewpew m4 that uses it and it seems it worked

wahoo, packet reception now works. I had failed to set the data direction of the RX pin to input, so while I could (somewhat surprisingly!) monitor the logic level RX signal on the board and it showed what I expected, the CAN peripheral didn't get any data in.

@thorny jay I didn't test it properly, but I did try 6.x with pewpew m4 that uses it and it seems it worked
@stuck elbow Thanks, I tested on my Sam minifig (single button) that is also M4 and it works. Will investigate further... maybe an M0 issue???
stuck elbow
possible
I didn't touch pewpew10 in a while, I recently have very little usable time
thorny jay
Does ugame use gamepad? I will have a new usb ID... so I need to test. ๐
stuck elbow
it does
wait, pewpew10 doesn't, it scans buttons as a part of metrix display routine
but ugame and pewpew m4 both do

@idle wharf - re read the docs links to GitHub - All items that are generated from init.c files have broken links - https://github.com/adafruit/circuitpython/issues/3400

Building the docs is hard. I ran into an issue with some Microsoft docs where whole sections were missing.

@slender iron Thanks for answering my flash question to unexpectedmaker the other day, looking at the build files had me baffled. I'm guessing bigger partition in general for esp32s2 is due to the added network modules, but curious why an extra bump on larger flash modules?
slender iron
just to give us more headroom
I'm worried we'll run out with ~1400k
and for really big things people will use an SD card

Trying to understand rotaryio and have found that CIRCUITPY_ROTARYIO = 0 in all the mpconfigboard.mk files- even the ports that list it as available in the support matrix on RTD. How does this flag work? Is there another layer of config that flips this prior to building it?
manic glacierBOT
Thanks โค๏ธ , i'll check what i've done (probably rewatch @tannewt video), and do a pull request on both adafruit/circuitpython and adafruit/circuitpython-org

Hello. Is there a single github repository where all the uf2 files are stored for the sample program which comes with each Adafruit device? I thought there was one but can't find it.
stuck elbow
uf2 files are not stored in a git repository
and they don't contain sample programs either
lone axle
Often (but not always) they pre-loaded demo contnet is available in the Downloads section of the device specific guides.
simple pulsar
@lone axle I spotted that for CLUE but not CPB with a very quick browse.
lone axle
@simple pulsar coincidentally I was just looking for the CPB pre-loaded demo the other day and Jerry had a copy of it that he was able to share with me. If you just need a copy of it, not an official source I can pass that along to you.
lone axle
It does seem to be missing from the main device guide for CPB though I did notice that as well.
simple pulsar
@stuck elbow Isn't https://github.com/adafruit/Adafruit_Arcada/blob/master/examples/full_board_tests/arcada_clue_test/arcada_clue_test.ino the sample progam that comes on the CLUE?
stuck elbow
no idea, but it's not a uf2 file for sure
lone axle
Yes, I think so. But it's not a uf2 file. It's .ino file.
tulip sleet
Usually the demos are Arduino programs that sometimes also serve as factory test programs
lone axle
I'm not 100% sure what Arcada is all the way. But I think perhaps CPB does not support that? which is maybe why it's not included in that repo.
lone axle
Just in case it becomes helpful. Here is the pre-loaded CPB uf2 file that Jerry shared with me. I'll be out for a bit.

Where's best place to read about vectorio ? I saw it mentioned on https://github.com/adafruit/circuitpython/releases/tag/5.4.0-beta.1 but the link's not working yet https://circuitpython.readthedocs.io/en/latest/autoapi/vectorio/index.html
Turns out it's over at https://circuitpython.readthedocs.io/en/latest/shared-bindings/vectorio/index.html#

I think there was an intention at one point to have a repo of the factory loads for each board https://github.com/adafruit/circuitpython-default-files It would be handy to have versioned firmware and software for each board as-shipped.
simple pulsar
@crimson ferry Yes, that's what I was thinking of, but I'd forgotten it was CircuitPython-centric.

@tulip sleet re CIRCUITPY_ROTARYIO my search didn't include the ?= makefile operator (it's new to me)- it's defaulted to enabled in /py/circuitpy_mpconfig.mk. Which I believe means it's enabled by default, disabled for a specific port/board. Which if I'm inferring the meanings correctly makes a lot of sense: py/circuitpy_mpconfig.mk defines which features are considered core platform ones (being disabled is for a port/board is an exception) and which ones are optional (being enabled for a specific port/board.)
tulip sleet
@hearty forge I think you've figured it out! Yes, the ?= is pretty new, and is easier to read

When we're building ESP32S2, we should be using the IDF as it is in the repo, not in our HOME directory (even though the setup process does put a copy there). And by this I mean we should use CP/ports/esp32s2/esp-idf/export.sh not the GET_IDF alias created in the IDF setup guide which runs HOME/esp/esp-idf/export.sh Correct ?
ionic elk
@tulip sleet do we have a specific variable for appending CFLAGS to make? So I can run something like make BOARD=blahblah BUTALSO=-Wno-unused-variable
tulip sleet
not that I know of
ionic elk
Thinking of maybe adding $(ADDFLAGS) for voluntary temporary warning suppression then?
for debuggin
tulip sleet
@ionic elk how about BUILDER_CFLAGS or USER_CFLAGS or something like that, to make it clear it's CFLAGS?
ionic elk
USER_CFLAGS sounds good
or maybe EXTRA_CFLAGS or ADD_CFLAGS? To make it clear that these are added on. Referring to a builder as a USER is always a little confusing
onyx hinge
whee, CAN bus error handling works now. If I provoke errors by randomly un-plugging the network wires I can get to BUS_OFF state, which leads to a restart and continuation of successful transmission. ```
'Sender ___' 254 _canio.BusState.BUS_OFF
RESTART
'Sender ___' 0 _canio.BusState.ERROR_ACTIVE
How fast is our NOR flash usually? In terms of SPI speed?

@idle wharf I use the idf in the repo. The tools live outside it though.
@ionic elk I think 40mhz or so

@ionic elk that is the speed cap for a given port. the chips themselves can usually do 40ish iirc

slender iron
DWT? on what port
slender iron
you are probably including the erase time
onyx hinge
a 512-byte memset() taking 3.2ms?
slender iron
that and writing 512 bytes is really reading 4k, erasing and then writing back 4k
ionic elk
No, this is just the actual SPI transaction itself for 512 bytes, occurring somewhere in the flash code.
slender iron
I'd suggest using a saleae to check SPI baudrate
ionic elk
DWT->CYCCNT = 0;
start = DWT->CYCCNT;
memset(data, write_value, len);
mem = DWT->CYCCNT;
result = HAL_SPI_TransmitReceive(&self->handle, data, data, (uint16_t)len, HAL_MAX_DELAY);
end = DWT->CYCCNT;
- or other logic analyzer
onyx hinge
lunchtime, I'll read back later
ionic elk
Well, the actual speed isn't too big a deal, unless you suspect that's way to slow and might be another issue. The end conclusion is that adding the memset adds about 1-2% of the read time
onyx hinge
If you're measuring just the TransmitReceive time of the SPI transaction, it should be about the bit rate divided by the number of bits (which is 8 times the number of bytes)
ionic elk
Backing up, this is all trying to figure out whether we should double the size of SPI_Read's write_value variable, so it can have an "invalid" state that implies we don't care about the value of the write line during a read. That lets us skip the memset and only do an SPI read instead of a transaction. I don't personally know enough to judge whether a 1% to 2% loss is worth putting in a change like that
onyx hinge
That number looks close to 1.28MHz, what bus rate are you looking for
onyx hinge
a function parameter generally doesn't "cost" more if it's 32 bits than if it's 8 bits
(the first 4 parameters to a function are passed in registers, which are all 32 bits)
ionic elk
So (543700 - 12368) = 531332 clock cycles via DWT, x (1/168MHz) = 3.16ms, /512 bytes is 161.8 kB/s, right?
@onyx hinge my concern with the API thing is whether it's worth the time to change all the APIs and whether it's considered a breaking change
ionic elk
I can at least confirm that the SD card seems to be working?
ionic elk
Running the read directory sketch from here https://learn.adafruit.com/micropython-hardware-sd-cards?view=all#tdicola-circuitpython seems to do what it's supposed to, spits out all the invisible junk that my mac put on the card ๐
onyx hinge
adafruit_sdcard defaults to 1,320,000 bits per second SPI rate which is close to the time you are seeing in HAL_SPI_TransmitReceive (1.3MHz/8/512 = 3.15us)
onyx hinge
reference for baudarate of adafruit_sdcard: https://github.com/adafruit/Adafruit_CircuitPython_SD/blob/master/adafruit_sdcard.py#L104
onyx hinge
.. so the SPI transfer is taking the expected length of time.
how long is the 512 byte memset() taking?
ionic elk
yes, thanks! Sorry I thought you were talking about bytes/s
onyx hinge
it is confusing and I could be clearer. I am just familiar with always operating in bits when talking about SPI rates so I didn't call it out as well as I could have.
ionic elk
So everything is fine in terms of SPI speed. The memset takes 73.6us
I added the timings in the OG issue: https://github.com/adafruit/circuitpython/issues/3176
onyx hinge
ah I saw it go by but then couldn't find it here in discord
ionic elk
3 byte flash setup read: 886ns delay vs 91ยตs read time (~1%)
512 byte flash read: 73.6ยตs delay vs 3.2ms (~2.3%)
onyx hinge
Let's consider the 512 byte read, but at a variety of rates. We can predict how long the SPI transaction will take at different rates, and that the memset will take the same length of time in each case
manic glacierBOT
ionic elk
^ see above for actual DWT cycle numbers
ionic elk
right exactly, this is a set delay
onyx hinge
at 8 MHz, 512 bytes would take 512us, so the overhead of 74us becomes 14%.
ionic elk
1Mbaud seems pretty standard, the BMP280 and several other sensors run off of it. What are some devices that go up to 8?
onyx hinge
SD cards are operated at 8MHz by sdcardio https://github.com/adafruit/circuitpython/blob/main/shared-bindings/sdcardio/SDCard.c#L47
ionic elk
14 percent is pretty gross, but will it matter for those applications?
onyx hinge
compared to not working at all it'll be awesome
slender iron
it's a good start
onyx hinge
24 clocks to memset 1 byte is slower than I expected.
ionic elk
Well, I was asking all this to see if the API change was justified. My impression is that it is.
slender iron
what API change?
onyx hinge
no API change, just implementing the write_value of SPI.readinto on STM32
