I have a map of reserved pin/timer instances. But I don't have a general manager, that's what I'm writing right now
tulip sleet
so just take a gander at the atmel and nrf and see if they are worth cribbing from. ... do you have an answer for @half sedge ? Maybe just "not yet"
onyx hinge
@ionic elk taking your example of rgbmatrix .. in fact, rgbmatrix uses a lot of pins. Don't the others? Maybe when requesting a timer you can say "and here is a pin I'm going to squat on, so maybe see if I can have that one"?
ionic elk
@tulip sleet yeah I'm looking at your stuff and Scott's right now, along with micropython. I don't think it'll be an exact fit but it's good to know the gist
half sedge
@tulip sleet I am going to use time.monotonic() rather than time.time()
Maybe that works.
ionic elk
@onyx hinge that's a good idea, starting the search for timers within pins that the module itself is preventing from being used for PWM
Ok well lots of stuff to try here, thanks @tulip sleet @onyx hinge
onyx hinge
you're welcome
half sedge
@tulip sleet It works with time.monotonic() as the usage was a loop with a timeout like explained at the end here: https://learn.adafruit.com/arduino-to-circuitpython/time
tulip sleet
@half sedge I'm assuming we just haven't yet implemented an RTC API on at least some STM32 chips. I know that some have real date/time clocks built in.
half sedge
I am trying to use the FeatherWingEnviroPlus from Pimoroni on my STM32. And Pimoroni code is very not CircuitPython minded as it is their first FeatherWing. That will keep me busy for some time I guess.
ionic elk
No RTC on STM32 yet yeah
half sedge
Fine for me, I solved that even if the solution is a bit monotonic. 🙂
Now I fixed their particul sensor that use the same kind of code.

@trim elm and anyone else that may be interested: I've got the very basics of the layout system code pushed into a repo now: https://github.com/FoamyGuy/circuitpython_display_layouts I need to read up on the cookie cutter system a bit and probably make a new repo eventually. But for now the library code and a basic example are in the repo.
It's likely bit rough around the edges. I don't have a lot of experience designing class based APIs in python, there is surely some room for improvement.
I am very open to feedback on the JSON structure and language in particular as well. It's better change names and structure of it early on now before there is any layout code out there to get broken I think
tulip sleet
@slender iron there are some deprecation renaming things we could do for 6.0.0 that are already 6.0.0 milestone issues: https://github.com/adafruit/circuitpython/issues?q=is%3Aopen+is%3Aissue+milestone%3A6.0.0: 3007, 2853 2082
simple pulsar
@half sedge Is time.monotonic_ns() available on the board you are using? That's better as it doesn't suffer from reduced sub-second precision over time.
thorny jay
@simple pulsar I will give this a try, however I would need something that works both on CP board, but also on Raspberry Pi. Those library I try to fix are from Pimoroni, so to be accepted change need to be portable.
It is just a timeout active loop. It will never last long and precision is not an issue I believe.
simple pulsar
@half sedge it's long uptime that messes up time.monotonic() - I wrote about it in https://learn.adafruit.com/clue-sensor-plotter-circuitpython/time-in-circuitpython
trim elm

This might just be general how-to, but since it is also ESP32-S2 I’ll ask here.
I have my ESP32S2 WROVER mounted on a breadboard with a USB-C breakout (PN 4090). I get header to header connectivity (i.e. from the pins on the boards) from D- to 19 and D+ to 20, but when I plug in to my MacBook, I do not see a USB Drive mount nor do I see a serial device at /dev/tty.*
When I plug in the WROVER on the non-native USB, it does mount and I can use screen and see CP load.
I swear this worked the first time I plugged in to the native USB via the breakout and never again. I've tried with the ESP32S2 Beta build and the June 23 build and another nightly build as well. All the same.
Is there something finicky about my setup or something else I'm missing entirely?
This isn't an urgent thing, I just want to figure it out. 😉 tx!
I posted this earlier, but everyone was mid conversation. I should have waited for a lull... any thoughts on if is this a general issue with USB breakout boards, or something specific to ESP32S2 or the WROVER?
crimson ferry
@idle wharf I had some weirdness early on with the CIRCUITPY drive unmounting and remounting repeatedly https://discordapp.com/channels/327254708534116352/327298996332658690/714651598831222865, but I haven't seen it since. I have same the connections you describe but with the micro-USB breakout, with breakout ground to board ground.
I think I cleared it up by erasing before flashing, something I'd been lazy about with standard ESP32 boards (Arduino IDE, or NINA firmware).
idle wharf
Hmm I do erase and I have GND to GND.
Is erase a complete wipe? Nothing is left behind?
crimson ferry
I'm not sure of the process. Do you see any evidence of a connection with system_profiler SPUSBDataType?
I actually power mine from the onboard USB connector, and just use data and ground on the native via the breakout (monitoring both with separate screens), but I can't see why that would make any difference.
I assume the red LED is on.
idle wharf
OK, that's an interesting idea the power. I'm going to try that.
🎉 @crimson ferry That was it! Power from the onboard USB and then D-, D+ and GND on the native usb.
Thank you !
crimson ferry
Great you have it working now! I’ll play around tomorrow, checked the schematic and not sure why it would behave like that.
idle wharf
I got back into the not working state. I think if you don't eject.
I'll try some test and save my notes for a more reasonable hour. 'night !
lucid solar
@idle wharf Just so you know, I've had it working fine powered both from onboard and external USB. I've also had them plugged in at the same time as I have a shottky diode protecting reverse current.
One difference is my external is a usb-mini-b, not usb-c.
idle wharf
Yeah now it works off the breakout just fine. I can unplug and plugin without ejecting. I think eventually it make OSx unhappy and it stops recognizing until a reboot.
Anyway.. its working great for a very early build on a devboard. thanks Mark !
onyx hinge
I'm excited to have that PR merged

@slender iron @tulip sleet just an FYI for now -- still looking into this -- I put together one of Scotts saola-feather adapters and have been testing it -- It seem to be working fine with one possible issue - twice I have had my linux box hang up when I disconneced the USB (in the feather side) from my system., I had to powercycle the linux box to recover. In both cases I had not actually ejected the CIRCUITPY drive. It does not happen every time - I'm just curious if you have run into this with your saola's either with or without the feather adaptor.
slender iron

I've had this box lock up before when connecting/disconnecting boards - I though it was a bootloader issue but maybe not ... I'll keep working with it to see if i can track it down...

@solar whale As I mentioned in the past, I have been having a lot of trouble with linux kernel crashes when I reset a board (it was specially an nRF52 at the time). I interposed a generic USB2 hub in between the host and the board, and the problems stopped. I still have that kernel bug report in about this, but the hub seems to be a workaround.
silver tapir
@solar whale @tulip sleet on what kernel versions did the lockup happen?
I'm on 5.4.0 (ubuntu 20.04) and been testing a saola on the feather usb side and had no problems yet.
solar whale
@silver tapir I'm on same 5.4.0 20.04 -- I don't se anything indicative of a USB issue in the dmesg logs at the time fo the hang. I'm waiting for a backup to finish before I start plugging/unplugging again. I need to take my dog for a walk now - but will see if I can clarify this more when I get back.
silver tapir
I'll try to see if I can replicate it with some hardware I have here.
@solar whale Also, what cpy version? Nightly-ish?
solar whale
yes -- built this morning -- I think it is one commit behind
silver tapir
Same here. Thanks for info.

One other piece of information -- the 2 hangs occurred with a saola-wroom unit. I switched to a wrover, but have only tried it once -- then the backup started ....

@silver tapir See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871143. I have not tried with an ESP32S2 board, but have seen the problem with SAMD21 and nRF52840, so I think it may be some kind of generic timing problem. I tested kernels way back in time and up to the latest 5.7, so this is a long-standing issue. It does not seem to happen on certain USB hardware on the motherboard.

does SPI already work on the ESP32-S2?
lone axle
I think that Scott got it working to some extent yesterday and showed an example on Show & Tell last night. But I'm not certain whether it is fully working or if his code is available online anywhere yet.
In the demo it seemed that a screen and a temp sensor or something like that were hooked up and working.

tidal kiln
maybe needed before instantly doing the subsequent read? to give it time to send everything...
could maybe done fancier? like loop/read/check amount read/break?
something like:
while self._uart.in_waiting < 2:
pass
maybe?
@trim elm ask them what they did maybe?

@simple pulsar does this have it?
https://circuitpython.readthedocs.io/en/5.0.x/shared-bindings/busio/UART.html
so...could maybe specify the number of bytes in read also?
@trim elm i think what's there is pretty hackish, so good chance it could be optimized better, but would want to test whatever changes to make sure

Yeah

I just removed -werror for now
onyx hinge
What system are you building on? I haven't seen this on amd64 linux.
crude blaze
WSL with Ubuntu 18.04
onyx hinge
that's what our CI runs, so you can see all the steps it performs in .github/workflows/build.yml (well, wsl is not involved, but it should not be relevant either)
crude blaze
yea I wouldn't suspect anything be different in WSL except for some driver stuff
onyx hinge
what line number is MICROPY_NLR_SETJMP error on?
(I didn't look whether for some reason this area of code is changed in tannewt's branch, assuming not)
crude blaze
../py/nlr.h:63:0 and ../py/nlr.h:39:0

I get CMake Error: The source directory "/mnt/f/circuitpython/ports/esp32s2/build-espressif_saola_1_wrover/esp-idf" does not appear to contain CMakeLists.txt.
which does make sense build-espressif_saola_1_wrover/esp-idf is empty. Is there a step that copies or symlink the idf from ports/esp32s2/esp-idf that fails for me?
idf is there and I ran their setup and env script, seems to be setup correctly
crude blaze
fails at https://github.com/tannewt/circuitpython/blob/esp32s2_busio/ports/esp32s2/Makefile#L216
not sure why
like does it expect to already be there or would cmake do this at this point?
ok -DCMAKE_TOOLCHAIN_FILE=$IDF_PATH/tools/cmake/toolchain-esp32s2.cmake is missing the () around IDF_PATH but that doesn't change anything

lemme run an upgrade, maybe stuff is just very outdated I dont often spin up WSL
hm no change
crude blaze
ok interesting, I manually upgraded cmake to 3.16.8 and now it works 🙂
maybe add a check for the version in the makefile?
probably a fair few people who will run into this who are staying on 18.04 for a while longer
crude blaze
I will check it out when I got it running
now failing at linking unfortunately
oh I didn't know cmake got a built-in command for version check, thats nice

I thought that the IDF came with its own copy of cmake. from build.yml: $IDF_PATH/tools/idf_tools.py --non-interactive install cmake
that version of cmake is probably added to the environment of the build shell with source $IDF_PATH/export.sh shortly thereafter
cmake is /usr/bin/cmake
jepler@babs:~/src/circuitpython/ports/esp32s2$ source esp-idf/export.sh
...
jepler@babs:~/src/circuitpython/ports/esp32s2$ type cmake
cmake is /home/jepler/.espressif/tools/cmake/3.16.4/bin/cmake
It would be awesome if someone took the time to move the relevant steps into the documentation, because knowing to check what github build.yml does is a bit obtuse

@slender iron how are you flashing the s2? I'm using esptool directly but I think I'm doing something wrong, the native USB device is never recognized after flashing.
solar whale
The native USB device is on different pins (19, 20)
D- is on 19 , D+ is on 20
@crude blaze is that what you are asking about for the S2?
silver tapir
@crude blaze This is an excellent guide for starting with the S2. Need a proper version of esptool... it's all covered here.
https://gist.github.com/askpatrickw/0a276c7e2d4f54e442b2cb6eaa0d32ea
crude blaze
@solar whale yes thanks I got that hooked up :)
@silver tapir awesome thanks been looking for something like that!
silver tapir
@crude blaze Oh, don't mind me... the guide was done by @idle wharf.
And it is a great start for the S2.
crude blaze
hm seems I'm doing all the same stuff
odd
official builds also fail so I guess it gotta be upload related
silver tapir
What command fails?
crude blaze
or I still somehow have the wiring wrong after quadruple checking it
oh just cpy in general 🙂
doesnt boot up after flashing
silver tapir
@crude blaze So, for uploading with esptool you use the built-in usb port.
crude blaze
sure uploading works fine
silver tapir
After flash is working, then you have to build or buy a usb cable, and connect directly to the pins in the guide.
crude blaze
but the native usb port does not come up as a device after that
silver tapir
(gnd, 5v, 19 and 20, disconnecting the other build-in usb)
solar whale
did you power cycle or reset after flashing?
crude blaze
I did power cycle yes
silver tapir
@crude blaze in the case of the cable I was using, the colors white and green where backwards, so I tried reversing them.
The ones that go to pin 19 and 20.
crude blaze
in case I'm just brain dead today
solar whale
there was an erro on the Adafruit product page, but it has been fixed
manic glacierBOT
crude blaze
is there maybe a known issue with windows and tinyusb on the esp?
silver tapir
@crude blaze Do you get the serial port but not the storage drive?
crude blaze
complete malfunction, no usb enumeration at all
manic glacierBOT
crude blaze
what I would expect from an empty chip or a crashed firmware
oh no way
it is windows
works just fine on my ubuntu laptop
solar whale
cool! problem solved --- 😉
crude blaze
ok not fine, I can't write to the drive :D
but at least the drive shows up
silver tapir
@crude blaze For windows there is a driver upgrade needed, but for the build-in usb... not for the cpy one.
crude blaze
oh weird, now after power cycling it doesn't show anymore
silver tapir
I have not owned or used windows since w95, so can't confirm :þ
crude blaze
either some physical defect or just still a bug in tinyusb
crude blaze
my main goal was to upload the version I built from scotts branch, now I put the 5.4.0 build from S3 on it
solar whale
tyr the latest build from S3 https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/espressif_saola_1_wrover/en_US/
silver tapir
Should be 6.0.0-alpha0 now.
manic glacierBOT
crude blaze
so it was atleast partially the breadboard, hooked up to wires directly it at least shows up in linux consistently
though the msc drive is not writable
repl works fine though
silver tapir
@crude blaze What happens if you format the storage with the repl?
import storage
storage.erase_filesystem()
crude blaze
good point I will try that
solar whale
@crude blaze I just tried that on min and I had to power cycle after doing it. Came back OK
crude blaze
so for you it works on windows @solar whale ?
tulip sleet
also could you say in the issue whether it's windows 10 version 2004 or 1909?
solar whale
no -- not on windows - that was on a Mac
crude blaze
@tulip sleet ah right sorry
tulip sleet
it probably doesn't make a diff, but i've had BLE issues on 2004 vs 1909, and so there could conceivably be USB diffs too
crude blaze
oh for sure, I've been working with Windows in an exhibition context long enough to suspect every windows update to cause havoc 😄
solar whale
on Ubuntu Linux I also did the erase -- had to push RESET afterwards.
That is different than other boards
crude blaze
yep format did the trick 🙂
tulip sleet
@solar whale doing storage.erase_filesystem() is how I have been reproducing that Linux kernel crash (with M0 and nrf)
crude blaze
so all working on linux
solar whale
ruh roh 😉 worked once for me....

@crude blaze I have experienced several lockups of my Linux box when disconnecting the USB cable -- be careful out there.
tulip sleet
@solar whale so you have seen it just on disconnect and not reconnect? Do you think the USB connection might have been bouncing?
It doesn't happen on Scott's AMD Linux box, but he is usually using Mac. I see it on a conventional Intel desktop chipset, but can't reproduce on a laptop chipset. Seems to be driver realted
solar whale
possibly -- and i don't reacall it happening before I started using the feather adaptor --- I need to test that more -- it's a painful test.
crude blaze
but that is interesting to hear, that might actually explain an issue I have with a project where I get the weirdest kernel panics that seem to disappear when the USB devices are not connected
might just be a loose connection
tulip sleet
i tried bisecting the kernel, but I've gone way back in time and up to the latest 5.7, and I can still make it happen
solar whale
odd thing is that dmesg log shows nothing -- appears to be a sudden hang -- so a connection issue may be likely.
tulip sleet
i set up kdump and have stack traces in that bug report
crude blaze
@tulip sleet are you sure its intel chipsets then? on mobile its usually just intel chipsets but on desktop motherboards you will very often find another vendor chipset being responsible for a large portion of the ports
besides the intel one that comes with the main chipset
tulip sleet
it's possible; it happens a lot on my Dell Optiplex 7010; I can look up the USB hw; I haven't tested extensively on the laptop. It's a Dell Latitude 5250, also Intel

OK -- just killed my linux box on a board without the feather adapter -- glad to have cleared that up 😉

do you have any entree into the kernel dev folks who might look at this? I got a little bit of dialog in the bug with Kai-Heng Feng, but I think I mainly need to attract the attention of the right person

@ionic elk how would you like to see stm32f1 support added? sounds like they may be interested if you give enough direction
manic glacierBOT
This is working for me now on the 3.x live page. Looks great! Thank you sommersoft.
ionic elk
@slender iron my impression is more that they are requesting it as a feature, but I'm happy to provide more guidance if you want. F1 support would require making a new family profile in mpconfigport.mk and then moving through the basic modules to test and adapt where necessary.
also all of the linker files, changes to the makefile, startup links, etc
If you'd like, I could knock out the obscure basics in probably an hour or two and get digitalIO going, and then leave Busio and all the other stuff up to someone else.
slender iron
@ionic elk I'd rather you start to sketch out the steps for them to try. I think the chinese community is finally trying circuitpython and I'd love to get them more involved in development.
ionic elk
I get that but I worry the time to outline all the steps might take an equivalent amount of time to just doing it
because it's so spread out at the start, there's a lot of different stuff to modify
But if your primary goal is encouraging involvement than I can do a todo list up on github

@slender iron how hard to you think it'd be to grab the basics of ports/ and shared-bindings/ and just make a regular old C api out of it?
seems kinda tempting to me for some personal projects. It'd be nice to access my own STM32 code and I've got a couple projects that cant use python for speed reasons.
lucid solar
@ionic elk my advice on that...even though it's your code you want to use...if you're not using Python...then I'd 100% use Zephyr, I think it's very mature for STM32.
ionic elk
I mean zephyr and stm32duino both are pretty mature but I did not find zephyr to be that easy to get into. Very big learning curve.
lucid solar
Hmm, yeah I could agree...but I really think it's worth it. There is a ton of great samples and drivers available.
ionic elk
Plus it was hard for me to tell how much they actually implement, vs you just using the HAL? And I saw barely any drivers for external devices which is a HUGE timesaver for me
And I don't need any RTOS features
lucid solar
I would recommend you give it another shot. I love CPY, but I really think Zephyr is much more suited when you want to use c.
ionic elk
I'll try giving it a spin with ExpressionEngine and see how helpful it is for the SPI DMA stuff I need to do for that
I know a lot of people who use libopencm3 too.
But ultimately I still think it'd be kind of fun to be able to take a project you've developed in Circuitpython and then move it more or less one to one into C
slender iron
@ionic elk I think it's a neat idea but think the exceptions could be tricky to handle
only some of the common_hal apis return error codes rather than raise
ionic elk
Yeah I'd probably just have a python script that goes in and deletes or replaces those
slender iron
peripherals is the boundary that I didn't want micropython to influence
ionic elk
probably a big management script that'd convert the whole circuitpython codebase down into usable parts
@slender iron on that note do you think it'd be worthwhile to go through peripherals and remove explicit references to circuitpython/micropython?
slender iron
no, I don't think it's worth doing actively. just something to keep in mind when working on it
ionic elk

Does circuit python have support for advanced BLE features like multiperipheral/swapping centrals?
lone axle
I am curious if it is okay to use eval within a library with a method like this to validate the input before passing it to eval() or if it is something that should just be avoided entirely.
def is_safe(self, the_str):
print()
_safe_characters = "0123456789-+/*"
for character in the_str:
if character not in _safe_characters:
return False
return True
# ...
if self.is_safe(user_input_str):
return int(eval(user_input_str))
ruby atlas
@lone axle i'm always really wary of using evals...
But that said, eval has uses. can you do what you need with regexes?
lone axle
I am trying to solve some basic math equation essentially. It will have input like "160/2-42/2"
ruby atlas
hmm, yah, eval after sanitization might be your best bet, rather than writing a mini language.
onyx hinge
It can be a fun exercise to write a parser, but not if it's not what you are interested in doing, and maybe not within the constraints of CircuitPython
tulip sleet
@lone axle make sure to catch divide by zero, etc.
lone axle
Thank you. I will add that.
I may eventually dive deep enough to write the parser for the math part of it. In some ways it's being used within a parser as is. becuase the real input can start out something more like: "DISPLAY_WIDTH/2-WIDTH/2" and the appropriate values get swapped in before it makes it to the eval call.
I suspect it would take me a while to come up with one that works correctly at present time though.
I did find some CPython ones to study though when I looked into it last night
slender iron
@crimson palm not sure what you are asking exactly. as a central we do support multiple peripherals

This is all in C++ but I'd like to know if circuit python can handle it

I believe we have it set to handle multiple connections

Great, thank you! Is there any way you could point me to the CPy library I should be using to manage multiple connections? @slender iron

Oh interesting! No that wasn't me
Did you come to any conclusions with them? I can search the discord if need be
tulip sleet
@crimson palm I think I found it, but I think the person was trying it in our Arduino BLE library, not CircuitPython. Here's an issue, that might have come from that discussion: https://github.com/adafruit/Adafruit_nRF52_Arduino/issues/517. I'm beginning to remember some more details, let me keep searching

crimson palm
Thank you very much @tulip sleet! So according to this there is no way to have this functionality on the feather atm, is that right?
tulip sleet
The Arduino implementation is not the same as the CircuitPython implementation. No one has tried it in CircuitPython, as far as I know. I am not sure if two centrals can initiate a connection based on the same advertisement, or whether you need to start a second round of advertising. We did not have the multiple central model in mind when we were coding, so it's possible it would not work, but it might work by accident.
just try advertising, and don't stop advertising until you get all the connections you want. or keep checking how many connections you have
as tannewt mentioned, we allow multiple connections
crimson palm
Alrighty, I'll give it a shot and let you know what I find. Thanks again!

I wanted to have that ItsyBitsy BLE be a BLE mouse to two computer simultaneously (or maybe as many as possible). This is to help teleworking and avoid losing the VPN or the VDI. I want to be able to connect to this BLE device and have the computer never go to sleep without beeing an annoyance (micro mouse movement every second are OK.

I took a closer look at my bread board. Turns out I chose the exact point where the breadboard had a short which caused D- to short to VBUS. It's an intermittent short and I guess Linux was more tolerant to that.

@mental nexus I think a recentish change to Adafruit_CircuitPython_Display_Text has broken one of my applications and possibly more. When you have a moment, could you take a look at https://forums.adafruit.com/viewtopic.php?f=60&t=166798 - I'll mention @lone axle too in case he's working in this library at the moment.
lone axle
I can look into it in a bit. I think the background bmp fixed baxkground colors for custom fonts
Not sure why it would effect max glyphs. Perhaps that is just passing through to group size
simple pulsar
The backgroud has "stolen" the last character so you now need max_glyphs of 6 if you want to (later) show a string of 5 characters.
BTW, to return to previous discussion I have recent libs and I do see anchor_point changes taking immediate effect.
lone axle
Yep, max_glyphs is getting passed through to max_size of the Group __init__()
and it looks like the case where text was included in the constructor accounts for the extra 1 needed by the background. But the case where text is absent and max_glyphs is used instead doesn't account for the extra 1 that I can see.
Going to make some ☕ . I'll try tweaking it to account for the extra 1 in that case.

@raven canopy unrelated to that but since you're here 😄. I am looking into setting up RosiePi, I found a few different repos related to it. Is this the place I should be working from to get my setup started? https://github.com/physaCI/RosiePi_Ansible

@crimson palm I have updated my Gist with a BLE+BLE version of my mouse jiggling. It is just a proof of concept, the code is not bullet proof, but it possible to advertise again after the first connection. So it can be periferal to a first central and periferal to a second one. But you can only advertise one thing at a time. @tulip sleet I might have found a bug (or it is my code) but the "mouse2" also get the HID event I try to send to "mouse1". It is not an issue for my usecase, but maybe you should have a look.

lone axle
@raven canopy I think I am ready for an PhysaCI access key. The ansible process finished while I was out but it seems everything completed successfully 🎉

@simple pulsar print("Testing...", file=sys.stdout) is implied by print("Testing..."), so with some abstraction on what file= gets assigned, maybe you can achieve what you're after

Dear @lone axle and @solar whale, beeing able to build CP on a Raspberry Pi would be really great. I'll give it a try using the guide and the exchange here. I don't have a Linux server always up, nor a powerfull machine where I can spawn a VM but I have Pi4 that I can keep running or quickly boot. This is for me the equivalent of a VM. I don't care if it is slow, it cannot be slower than when I was compiling the Linux kernel on a 386sx. It's easy to dedicate a USB key or a microSD for that particular use and boot on that whenever I need to build CP. Right now I have limited myself to library stuff that I can do in Python, but I am sure there is fun on the C side.
lone axle
I did end up getting a successful build once I got the correct gcc. I've never build Circuit Python directly on a nice PC, but anecdotally the build on the Raspberry Pi seemed pretty comparable in time taken to when I build using a VM in my laptop.
I may end up going back through the process another time and trying to document every step in a readme.md somewhere. I could see myself referencing back to that if I do make it.
Jerry's link to the gcc saved me a ton of setup time before I would have been able to make the build.

That would be great.
solar whale
@thorny jay I had to build the arm GCC toolset locally -- send me your e-mail address in a DM and I will provide you access to it
or you can build it -- only take 8 hours on a Pi 4
raven canopy
on Ubuntu Server, firmware compiles take around 6-9 minutes for me. RPi 4 is a little quicker than a 3B+. booting from SSD didn't speed it up as much as i thought it would, but haven't booted the 4 from SSD yet.
i also need to test -j[2,3,4] on the RPi 4. j2 helped a little on the 3B+ for me.
thorny jay
While the SSD surely help and the USB3 also, it is more for reliablilty compare to SD card than for anything else. Also space from the SSD is great.
raven canopy
yep. in my context, the SSD reliability is the driving factor. the speed will just be a perk. 😄
solar whale
each board build only lake about 3 minutes on the P4

i wonder if its the Raspbian/32-bit improvements over the Ubuntu/64-bit "shimming". i've read reports of 64-bit operations taking a bit longer vs 32-bit.

@ionic elk is that H7 you are talking about is STM32H7 (like on that Maximite I was talking about)?
slender iron
@ionic elk if you end up with time this week, we should get you going on esp32-s2
ionic elk
STM32H7 yeah. Right now we support the H743, which is used on the OpenMV and some other high performance boards
I haven't seen the maxemite but if it's available online I can grab one and add support.
slender iron
looks like the maximite is 743 too
uses this dev board: https://www.waveshare.com/coreh743i.htm
ionic elk
@slender iron I'll start reading the docs for the ESP32 and put some notes together if I have time
Is there something in particular you'd like help with so I can focus on it?
what's this actual maxemite thing, does somebody have a link?
slender iron

are the F743i and F743zi essentially the same? STM's models number confuse me at a certain point. 😄

STM32H7 yeah. Right now we support the H743, which is used on the OpenMV and some other high performance boards
@ionic elk Maximite is using this: https://www.waveshare.com/coreh743i.htm
ionic elk
@raven canopy I assume you mean the H7, here's the grid: https://www.st.com/en/microcontrollers-microprocessors/stm32h743-753.html
raven canopy
i did yes. haha. see...confuses me. lol
slender iron
I wonder if you could enable both CS lines at the same time
I guess that's bad because then they both drive MISO
ionic elk
@raven canopy the exact naming scheme for STM32s is this: for the H743ZI, H7 is the family name (high performance M7/M4 combo chip tier), 743 is the line number (these can seem kind of random but have certain trends across families), Z is the package type (100pin LQFP, always uses this letter across all families) and I is the RAM/Flash combo (which are arbitrary per chip line)

@tulip sleet So isn't just me having the problem.

When I wrote the plotter for the clue I noticed there was no (standard) way on the APIs for finding min/max for sensors

@inland tusk no, a number of people using Linux on various platforms have been bitten by it

I just reurned 18.04 to avoid it
tulip sleet
i was getting this on 18.04 also
inland tusk
It was intermitent for me in 18.04
prime flower
@tidal kiln yes, I meant that the sensor properties would be part of the sensor library design much like universally calling sensor.temperature in a temperature sensor lib.
simple pulsar
For sensor ranges, the abs_min / abs_max values in here are me either looking at data sheet, looking at library code, getting values from testing, or guessing: https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/master/CLUE_Sensor_Plotter/plot_source.py#L342-L378
onyx hinge
e.g., sensor.min_temperature = -40; .max_temperature = 100; .temperature_resolution = 1/256; ?
we could release 5.3.1 with the new names
prime flower
@onyx hinge yeah, but min_value instead of min_sensorType since it'd need to be across all sensor types (ref: https://learn.adafruit.com/using-the-adafruit-unified-sensor-driver?view=all#sensor-t-sensor-details-161325-18)
slender iron
onyx hinge
@prime flower but say you have an AHT20 (?) and it has .humidity and .temperature .. it then needs 2 sets of min/max/resolution right?
@raven canopy random neuron firing: can we help people in getting "main" branch when they use cookiecutter, or is initializing git distinct from running cookiecutter so that's not possible?
prime flower
yeah, ICs with multiple sensors are tough in that case..
raven canopy
@tulip sleet for eventual removal of API, maybe just throw in a Deprecation Warning print, based on versioning? not sure how far they'll propagate beyond library dev...
tidal kiln
@prime flower sort of reminds me of "transducer electronic data sheets" (something i ran into in a previous life)

Hi all, new here. I have a question regarding CircuitPython and particle products. I have a Particle Argon that I can convert over but I was wondering if anyone knows if doing so gets me wifi with that board? I’m going to connect it to a mqtt server and that board does have a built in wifi chip cause it’s accessible via particles code.
lone axle
@placid stirrup I am not 100% certain because I don't have any of the particle devices myself. I believe the deal is that if you use Circuit Python on the particle Argon at this time you cannot make use of the built-in wifi. At present time if you want to use wifi I think you would need to use an AirLift featherwing or other ESP32 breakout device with NINA firmware to act as a co-processor.
Even though the argon device has builtin wifi, I think Circuit Python does not have support for using it.
placid stirrup
Ok thanks for the answer 🙂
viral minnow
Oh wow my sound was so bad on the recording really bizarre, sounded like the wrong sample rate
onyx hinge
@viral minnow yeah it sounded odd to me but I could understand you so I went ahead with things. If you would like to do a mic check between now and the next meeting, just let us know.
viral minnow
@onyx hinge thanks and yes please when you have a chance, I think I had the wrong sound input source selected here.
onyx hinge
@lone axle three possibilities for capturing images from displayio: 1, there is a method on Display to get the content of one screen line, and a library can make a bmp file out of it. I don't have the link handy. 2, if you settle for small displays perhaps framebufferio can help. 3, you could do it on the blinka implementation which might have additional options for capturing output
@viral minnow I could hop back on the voice chat now if you don't mind the sound of a 3d printer in the background
crimson ferry
@lone axle @placid stirrup I think the issue is that the ESP32 on the Argon doesn't have the right pins exposed to use ESP32SPI and the NINA firmware. I believe some folks have used the AT command protocol with that firmware, but I don't think that's really supported anymore.
lone axle
Oohh Neat! Thank you! I like the idea of using Blinka so the images can get stored on the Pi and I don't have worry about transfering them anywhere.
I have a tiny bit of experience with Pillow, I may be able to figure out how to get it to save out a file.
slender iron
@prime cove Looking at it now. I'd probably just implement __get__ and __set__ rather than having read and write as well.
You probably want __len__ as well if you know the length
placid stirrup
What would you guys say is the go to device that has wifi built in? Is it that little m4?
slender iron
Ideally, it'd be a drop in replacement for nvm
@placid stirrup right now the airlift line
I'm actively working on ESP32-S2 which will be a good option soon.
placid stirrup
Awesome I’ll look into those
prime cove
@slender iron Thanks! Is it just a semantic thing then? I.e. I should change"read" to "_read" and remove it from the example?
placid stirrup
Mqtt is implemented in CircuitPython correct? I think I saw the library.
Are there any issues with it to be aware of?
slender iron
@prime cove ya, a style thing. Basically, having one way to do something means more consistency in the code that uses it. By mimicing an existing API, it's easy to swap your object in as well.
another python style thing is separating words in names with _ rather than caps

@onyx hinge @ivory yew Holy cow! With ulab, I was able to reduce the automatic Eurorack cable discovery process latency from 15.8ms to unmeasurable (using time_monotonic())! Code is much simpler as well. Going to set this aside for a couple of hours and see if it's really true when I return. Thank you @onyx hinge for the incredibly helpful learning guide! UPDATE: after averaging 1000 iterations, it looks like the latency is 0.876ms, well under my 1.0ms target. Special thanks to @lapis hemlock, as well.
poll_pin.value = False # set polling voltage to 0v (high impedance)
inputs = ulab.array(read_inputs()) # read inputs before testing
poll_phase_one = ulab.array(inputs < 1000) # create no-cable mask
poll_pin.value = True # set polling voltage to 5v
poll_phase_two = ulab.array((read_inputs() * poll_phase_one) > 20000) # mask with first test results then check for polling voltage change
return poll_phase_two, inputs # return with result mask and raw data

solar whale
@onyx hinge some interesting developments to ponder over your morning coffee --First, sdcardio is working well on my feather_m4_express! I have been workin on the strange SDCard issue I found yesterday - no difference using sdcardio BUT I found that is is only an issue with the TFT featherwing -- It does not happen with an SDCard breakout board replacing the TFT. It is related to the specific HW config of the TFT featherwing. The plot thickens...
simple pulsar
@solar whale I have not used feather wing but have a TFT Gizmo on a CPB nowadays. That has some interesting characteristics for the screen being active. CircuitPython "remembers" the screen has been used and it stays active after that as a serial console. Is that the same on the TFT feather wing?
solar whale
@simple pulsar yes. It behaves the same
placid stirrup
Hey quick question, can I use an 8266EX to add wifi to a board?
Like to another board which doesn't have it
solar whale
@placid stirrup sort-of -- as in this guide https://learn.adafruit.com/adding-a-wifi-co-processor-to-circuitpython-esp8266-esp32 you can use the AT firmware via UART -- like on the Argon, but it is not the recommended path. using and ESP32 board via SPI will work much better -- for example -- with your Argon, you can add an "airlift" https://www.adafruit.com/product/4264
@placid stirrup another option I have used is to put Micropython on the ESP8266 for WiFi access and pass data via UART from a CircuitPython board -- then have the ESP8266 handle the WiFi.
MicroPython supports Wifi on the ESP8266 and ESP32
placid stirrup
Hmm
Ok, sounds good. Maybe I'll just look at getting the airlift m4 and be done with it. I can implement my little project on the Argon now but I so want to use python to do this instead
trim elm
hey @lone axle do you remember the settings you used to get the bitmaps to work with imageload? I'm thinking it could be worthwhile to add a few sentences in the README explaining what types of bitmaps do and don't work, and the ways to export those sorts of bitmaps in GIMP, photoshop if you have it, and using CLI tools.
lone axle
@trim elm Indexed BMP files are what is supported currently I believe. There is a page in this guide I made recently that covers the process of converting and editing them with GIMP: https://learn.adafruit.com/creating-your-first-tilemap-game-with-circuitpython/indexed-bmp-graphics
trim elm
Oh, great. I'll just put a link to that in the README
lone axle
@trim elm The one gotcha with the recent update to imageload is that BMP image files with negative heights are only supported on builds with longint enabled. Builds without longint can only render positive height BMPs.
trim elm
Ah
lone axle
I never knew negative height existed to be honest. If I understand correctly I think it's used to flip the contents before showing or something like that.
I'm not sure how to actually create a negative height BMP though. I just tested on the one supplied in the original PR that added it.
placid stirrup
I just remembered that I have a raspberry pi 2 sitting somewhere, hows circuitpython on one of those? I know it's kind of a different animal than what circuitpython is intended for
solar whale
@placid stirrup CP does not run per say on the RPI but you can use most of the CP libraries via the "Blinka" interface https://learn.adafruit.com/circuitpython-on-raspberrypi-linux
placid stirrup
Alright, I'll stop bugging you guys and read up on this. Thanks for all the help
solar whale
No worries -- Keep asking questions
@placid stirrup Using the CP libraries on your Raspberry Pi will work well. And you get to code in Python!
placid stirrup
Do the networking libraries work via blinka/raspbian? Gotta get that MQTT connection 🙂
solar whale
you use the standard RPi libraries for that -- use "blinka" to talk to the sensors.
or am I misunderstanding?
placid stirrup
Well what I'd like to accomplish is to have the MQTT client directly in the control code cause I want it to talk to the actual control program. It's all good I need to read up on this, maybe I'm thinking about it wrong. In something like the particle firmware you create everything is part of the control program, the control program calls the mqtt agent to publish/subscribe and as such push and pull data in and out of the program itself. I'm not familiar with how actually having a general purpose OS underneath complicates the matters
I'll poke around and see what the internet has to say
But ya, I want to do this all in python if I can
solar whale
Good luck and feel free to come back with more questions. There are many options!

@errant grail, @onyx hinge Great, but how does it work? The cable discovery process, that is. The question is not entirely academic: if I knew what is going on, we could, perhaps, shave off a couple of microseconds here and there.

The test first sets the polling voltage to high impedance. If nothing is connected, it’ll measure zero volts. If it sees any other voltage than zero, it knows a cable is connected.
However, a connected cable may have zero volts on it, so a second test is needed. The polling voltage is raised to 5v (almost any voltage above the noise threshold would work). If the measured voltage jumps from 0v (in the first test) to 5v, then we know for certain that no cable is connected. If it stayed at zero volts, the logic concludes that a cable is plugged into the jack.
I suspect that the actual polling pulse is very short, probably 100us or so. Going to scope it today.
Getting the detection latency of the code to 1ms or less means that it should work okay with CV signals < 1kHz. Need to confirm that assumption.

@errant grail But where do you need to crunch numbers? Do you filter (convolve) your analogue signals to beat the noise?

@lapis hemlock Nothing that sophisticated. I needed fast array processing to create masks for each test phase followed by a logical comparison of the test phase results.

def poll_inputs(): # determine if cable is attached to jack
poll_pin.value = False # set polling voltage to 0v (high impedance)
inputs = ulab.array(read_inputs()) # read input array before testing
poll_phase_one = ulab.array(inputs < 1000) # create no-cable mask
poll_pin.value = True # set polling voltage to 5v
# mask with first test results then check for poll voltage change
poll_phase_two = ulab.array((read_inputs() * poll_phase_one) > 20000)
return poll_phase_two, inputs # return with result mask and raw data```I tried setting dtype to uint16 for the values, but the floating default turned out to be the fastest.

With a bit of work, we could make this run faster. The problem is this poll_phase_one = ulab.array(inputs < 1000). inputs < 1000 returns a list of Trues/Falses, and then converts it to an array. That is a bit expensive. An update is in the works, where I treat Boolean arrays properly. I won't commit to a deadline, but it shouldn't be long before I can release that.
Another thought: we might want to implement any, and all for arrays. That would allow masking, instead of having to evaluate (read_inputs() * poll_phase_one) > 20000.

Yeah, boolean would be nice, but I'm pretty darn happy as-is!
lapis hemlock
I think I meant where, or something similar.

@errant grail A couple of weeks ago, the moderator bot deleted one of my comments with d.a.r.n. Odd.

I haven't done much more with ulab than scratch the surface, but I can see some great possibilties for it.
lapis hemlock
It is always a bit fulfilling to see what people do with your code. I definitely haven't thought of such an application.
errant grail
Interesting. Didn't realize the bot wouldn't like it.

I can help understand what the bot is doing if it ever moderates you when it shouldn't

@lapis hemlock In this case, ulab is more akin to the way I design hardware -- doing things in parallel whenever possible. Since I'm more hardware-oriented, it was nice to have something that matched that approach.

@slender iron I wasn't offended by the bot's pulling my comment. I understand that it is a bit borderline, when you do something similar to knitting🙃
Probably depends on the location, too.

@slender iron Can't be too smart since it didn't pick up on you calling it dumb. 😉
slender iron
exactly 😉
