you could reference micropython too

are you wanting to learn to port or are you wedded to that board specifically?

[adafruit/circuitpython] New comment on issue #7883: Fix \`abs\(\)\` warning in \`vectorio/Circle\.c\`

That abs on radius should definitely be removed. Thanks for noticing!

x&y math should have abs(). Circles are placed by their center point, so the math only needs to be concerned with the 1st quadrant. The other 3 are symmetrically mirrored with positive math. You could factor out the abs by doing signed math up to the end, but I think you might have to store 1 more variable if you did so. Dubious that it would read any better :-)

oh no ! All the cookiecutter libraries are impacted by the jQuery issue !!!

I'm having some issues around circuitpython hanging when using displayio. My current circuit uses an external SH1106 display, which is powered on and off using a separate controllable voltage regulator. I need to do this to limit power drain in deep sleep. The I2C rails are also connected to this switched power supply. My problem arises when the program ends - the power supply is turned off, but then I think circuitpython tries to display blinka (or an error message if there is a crash). This causes circuitpython to hang, and I am unable to connect via USB. I can see my laptop recognises that the USB device has stopped responding and eventually disconnects it. Access to the flash drive also stops working at this point

#

If I leave the display powered on then everything works fine. I've tried CIRCUITPYTHON_TERMINALIO=0 in the makefile - but still get the same problem

slender iron
#

@mystic flume call release_displays() before sleeping

mystic flume
#

I think it would be really useful to have an option to stop any terminal (and blinka) output to the display, either as an option in boot.py or when creating the displat

#

It's more of an issue during development, my device keeps freezing during testing if I get an exception

jaunty juniper
#

you could use atexit to release the display ?

mystic flume
#

@jaunty juniper I was just thinking that!

jaunty juniper
#

(as a workaround)

mystic flume
#

I'll give it a go

#

Ah - that works

#

Thanks folks

slender iron
#

generally freezes are loops that should be checking for interrupted state 🙂

#

a debugger can help find them

#

though most of those loops will keep usb alive

mystic flume
#

I'm still getting an error on soft reboot saying pin D8 is in use after release_displays is called

jaunty juniper
#

which is what ? The SCL pin ?

mystic flume
#

Sorry yes

slender iron
#

looks like I2CDisplay doesn't clear the never_reset properly

mystic flume
#

I've found that deiniting the i2c bus in an atexit call fixes this bug

slender iron
#

which will prevent it from being reset automatically

#

👍 that'll work

#

explicit deinit overrides never_reset

mystic flume
#

Yep - that works well enough for me now

#

Thank you all for your help - I can get back to my nerding now!

@dhalbert widening. So that circles at 256 < x or 256 < y can still be handled. I have some Adafruit displays with more pixels than that ;-)

If you multiply 257 * 257 int16's what do you get? :-) On the other hand, if you widen to int32, you can support nearly every positive position of int16 x and y. Ideally we'd widen to uint32 instead though because (2^15)^2 * 2 is 2^31, and that's 1 greater than 2^31 - 1! But it fits no sweat in 2^32. Int16.minval x and y will position at 0 I think. So v...

@slender iron I think I got the jquery issue wrong, though I'm not sure that I understand what is going on. There was something about the version of the theme being invisibly forced on older libraries or something ? I believe @lone axle would know about that.
The issue is that right now, none of the Adafruit libraries that I looked at have a working bottom left panel.

[adafruit/circuitpython] New comment on issue #7883: Fix \`abs\(\)\` warning in \`vectorio/Circle\.c\`

So I personally prefer to be explicit when bit width matters... I always forget what the rules are for implicit widening within a math expression :-( and whether I'm on an 8, 16, 32 or 64 bit pointer machine :-(, so it helps me read it. Maybe it's helpful to other people reading it to be explicit also? It's otherwise implicitly dependent on the size of int (or ptr, again I'm not sure, and being explicit makes me sure).

Also, I notice that below even after abs() we're using int16_t. On ar...

thorny jay
# slender iron I haven't seen that

It is my screen (actually an LG beamer) and I have other doing that.
On my big LG OLED there is a similar issue, that look like "overscan".
(overscan will typically eat the screen boarder for a full HD source, I have never seen that acting on low res signal)
However, there is a "Analyse Signal" mode that when enabled will display everything correctly.

#

Maybe one thing "special" about most TV/Screen at home is that over here in Belgium we are 50Hz (also PAL). But our TVs, expecially with DVI input should be able to display a 60Hz signal without problem.
So I am curious about other positive or negative report and from where they are coming.

[adafruit/circuitpython] Issue opened: #7887 ESP32 ability to disable serial

As I am doing the t-energy port, I discovered that as the battery discharges the serial chip spams KeyboardInterrupt's to the serial console.
It wouldn't be an issue since I could just configure the usb_cdc console to disable serial.
But that is impossible on esp32 since there is no usb_cdc.

This board hates me.

This could alternatively be solved by #7857, as non-interrupting data can be ignored.

The Wio Terminal includes a RealTek RTL8720D as a companion to the main chip to provide WiFi and Bluetooth capabilities via eRPC over a UART connection. The WIO Terminal schematic labels some pins as the RXD/TXD for the UART, and that was captured in the board definition for CircuitPython. However, these pins may be used for logging in another mode, but they are not the main pins used to communicate with the RTL chip. The correct configuration is RX on PC24/pad 2 and TX on PB24/pad 0 of SERCO...

I would say the device/server side is fixed if CORS support is desired (What problem is it solving??? Example, please).

Here is how I understand this:

The first implementations of tools using the web workflow were code.circuitpython.org trying to load API endpoints from the circuitpython.local web workflow. This would cause the browser to send a CORS preflight request to the board, so that request had to be allowed to go through, but not from any address for security reasons. I was my...

Attempts to resolve #7885

This PR adds minimum size validation that enforces the TileGrid being no smaller than 2x2, which is arguably still too small to be practically useful. Perhaps a higher limit would be appropriate?

If there is a desire to allow 1xN sized TileGrids the logic in this will have to get reworked.

Also something for consideration would be adding an example to the docs of terminalio module that illustrate how to use it. As noted in the issue there isn't currently any...

@slender iron I was trying to draw circle or turn on pixel on the DVI. The piece of code I had was creating a bitmap, using bitmaptools to draw, then display the bitmap with displayio. Adafruit_framebuf did seems like the way to go to avoid consuming twice the memory. But I have no clue how to make that work, maybe some typing secret that I don't master in python.

I am maybe also interested in some ulab magic where the framebuffer would be an array and you could do math to compute the next frame... but this is way above my head anyway.

ok I have ~4 questions. 1. the GPS class has two competing(?) attributes, self.horizontal_dilution and self.hdop. As far as I can tell, they come from different parts of the message or different protocols. Is what I've done enough to disambiguate them?

slender iron
#

I think the GSA vs GGA annotation makes sense

steady garden
#

cool, ok. q2: attributes true_track and mag_track are unused. do you know what they are?

slender iron
#

I don't know what happened to that code

steady garden
#

hmm ok. is it worth defining them do you think? If the relevant code is gone, I'm tempted to take them out

#

otoh, might be nice to have if someone comes back to reimplement the missing stuff

slender iron
#

I'd remove them if not set but its worth figuring out when they were removed and why

steady garden
#

ok, I'll do some research

slender iron
#

thanks!

q3: after a bit of googling, I'm sort of sure that sat_prns is "Satellite pseudorandom noise code". is that right?

slender iron

that I don't know

My attempt failed at the 13 hour mark because it doesn't have a graceful failure try/except if the broker doesn't respond apparently. This is my first time ever using mqtt so I don't have a snippet for that part. It's mostly using the default AdafruitIO example. Circuit Python really needs to include try/except error handling with all examples for anything MQTT or Requests related. Looks like mine failed inside io.loop() and I think that's something the library itself handles.

I have put together a demo or high-resolution DVI output.

It create a bitmap as big as the frame buffer, so it is very inefficient.

This works for 640x480 black and white.
It seems ok in 800x480 too.
But it fail if you want to go grey scale with 2 bits per pixel.

Also, most "turtle" attempt will fail as turtle reserve a frame buffer (I guess).

So either we get an addressable frame buffer from picodvi and can reuse that.
Or you have to draw with object in displayio, but don't ex...

Hi, build artifacts from merged PRs are uploaded to Amazon S3 with the board ID, which is the name of the board directory in the Circuitpython repository, and the path in the URL used on circuitpython.org. That is the S3 link you mention.
The board list on circuitpython.org is only updated when there's a release, unless a board is added manually in which case it will be listed at the end, with no release but a link to "Absolute newest" (which might not work if there is no finished build yet).

Why on Pico [W] can I set supervisor.runtime.next_stack_limit to something over 100KB, but ESP32-S2 N4R2 (QT Py) gets AttributeError: can't set attribute 'next_stack_limit'?

#

Pico [W] default stack limit is 24576, but ESP32-S2 QT Py (much more RAM) default is 16896.

@crimson ferry esp inherits stack sizes from the idf

#

rp2 manages it ourselves

crimson ferry
#

esp stack is fixed always, even with CIRCUITPY_RESERVED_PSRAM=?

slender iron

ya. reserved psram adds psram to the idf heap

crimson ferry
#

idf must manage b/c C stack always comes from on-chip memory that has to get shared / traded-off with esp-idf memory?

slender iron

it manages it because of freertos

#

I think it can place them anywhere

crimson ferry
#

thanks adds deep dive into esp memory onto bucket list 🙂

slender iron
#

I don't know much about it

#

the idf starts a main task for CP

#

and the IDF sets the size of the main task stack

and that's probably before we start to mess with PSRAM

#

a couple of people have been asking about pystack and recursion limits, so I was trying to understand the constraints better

they'll give different error. pystack exhausted vs recursion depth

Trying to create a duplicate of board.DISPLAY using picodvi.Framebuffer yields "invalid height" when trying to do 320x240x8 or "MemoryError: memory allocation failed" when trying to do 640x480x2 or 640x480x4.

Please post this code. x4 isn't supported.

These are the supported arguments and the resulting framebuffer. The larger versions will be hard to allocate from within CP but may be possible from board_init().

it is outputting 640x480

why does display.width print out 320? the code clearly says 640

The display looks like a 320x240 display

it looks like that because color pixels are doubled horizontally and vertically when transmitted to the display

okay so logically (to CircuitPython users), color display is 320x240, even though they pass in 640x480 to picodvi.FrameBuffer but physically the output is 640x480

[adafruit/circuitpython] New comment on issue #7911: DVI resolution is actually 320x240, not 640x480

Okay, after conversation with @tannewt in Discord, I see the problem. While you must construct picodvi.Framebuffer() with a 640x480 argument or using board.DISPLAY, the resulting display is reported as 320x240 to CircuitPython code, the actual monitor is driven at 640x480 with pixels doubled in both dimensions

I would still classify this as a bug. Shouldn't display.width and picodvi.Framebuffer(width=) have the same value?

If we can get the UM FeatherS2 running for about 72 hours total I think we can close this and hand everything over to #7490. @tannewt tagging this issue means it's already referenced as additional data for their uses over in #7490.

[adafruit/circuitpython] New comment on issue #7917: hit a whoopsi with character lcd

The common backpacks use a PCF8574, which is not supported by the Adafruit library. However, it should not normally crash for software reasons.

Are you powering the display and backpack with 5V? If so there may be 5V on the I2C pins from the pull-up resistors. This may cause a hardware issue with the Feather M0.

Do you have a link for the display and backpack, or if not, photos? How is it wired? How was it wired with the RPi, and do you have a link to that software?

#
paulrodgers
[adafruit/circuitpython] New comment on issue #7917: hit a whoopsi with character lcd

yes, its powered off 5v, e same USB power that runs the feather
I hear you saying that the backpack needs to talk to the feather at 3.3v on the I2C

makes sense, so If I unplug the I2C at the feather end it should no longer crash
will not work, but no crash. but thats not what happens, same result

BTW fantastically fast response, I was expecting tmw morning earliest

if I just get a new adafruit backpack will that run at 3.3v?

[adafruit/circuitpython] New comment on issue #7917: hit a whoopsi with character lcd

This is the latest version of our backpack: https://www.adafruit.com/product/292. The LCD needs 5v for proper contrast, but this new backpack upconverts the 3.3V to 5V. It will probably work with your display, but it's possible it wouldn't. We'd to know more about the display to check on that.

If you disconnect the I2C, you will get an error that there is no I2C connected (it will mention missing pullups).

This appears to be more of a support issue than a CircuitPython bug. I'm going to...

the ones i've seen were closed at most some hours ago, and some others are being worked on (PRs openned) during PyCon, so not something i would say needs to be checked/improved in any way (having a completely up to date page will take a hit on performance and outisde events its not needed)

however i will try and find other stuff that is solved but the issue isn't updated accordingly, and perhaps find something i can PR myself

Apparently try/except around the io.loop() doesn't help it fail gracefully.

@spare jacinth for the TCS library, We did some test and validation for the raw color, at the end we kind of agree that the PR from FR where not longer required as we included better explanations in the simple_test and in the library.

@spare jacinth regarding MAX7219, I think the FlantasticDan's idea is good, not sure why they did not make a PR, but we could make one and link the issue. And then, the solution could be discussed in the PR.

Don't think I need to continue with the UM FeatherS2 wifi/mqtt stability test. 53 hours in, feed update every 10 seconds, approximately 19,000 transactions to AdafruitIO over 2 1/2 days... not a single error let alone a hard fault.

[adafruit/circuitpython] New comment on pull request #7915: Add Pimoroni Pico dv Demo Base \(pico & pico w\)

The only possibly useful observation I've made from todays poking at this is that when Web Workflow attempts to connect to the AP using common_hal_wifi_radio_connect it fails with a timeout (WIFI_RADIO_ERROR_UNSPECIFIED) after calling cyw43_arch_wifi_connect_async. However, attempting to execute wifi.radio.connect('ssid','password') from the REPL immediately crashes apparently without entering the common_hal_wifi_radio_connect module.

Some feature I find missing from keypad library:

    In keypad.Keys if pull=True, the pin is always pulled to the opposite of value_when_pressed which prevents the use on normally closed switches without external pullups.

If I remove the pin_alarm the time_alarm works consistently.
With the pin_alarm enabled I see wildly inconsistent results (even though nothing was connected to the pin);
sometimes with the alarm getting called constantly, and sometimes including a hard crash:

[adafruit/circuitpython] Pull request review submitted: #7921 Add additional iMX RT support

Glad you got these working. A few minor things.

I think it would be better to call these boards nxp_mimx... instead of just mimx.... I know the first one was not named that. I would really like to see the manufacturer included in the board name. I know we haven't been consistent, and it's going to be a job to rename them all. So if you don't want to do it now and we do it in a big bang later, that's OK.

onyx hinge
#

so the sck vs dqs change is unrelated to the bump in flash speed @slender iron ?

slender iron
#

@onyx hinge ya, though I think we do need a loopback from a pad to be faster

#

instead of looping back internal to the peripheral

tulip sleet
slender iron
#

maybe we do it with 9.0 and do all ports then too

tulip sleet
#

yah, that's what I was thinking, so a few more boards named in old style now doesn't make much difference, and we may as well keep all the mimxrt evk's the same for now

Onto the UM FeatherS3

#

@tulip sleet It does seem like the MMQTTException was never being caught properly by my try/except attempt. I was catching OSError and RuntimeError's np. I have no idea if rolling it into RuntimeError is a good idea or not, that's way above my level of understanding, that's up to you devs. I only know how to use them to get around scripts from crashing which is important for online retrying stuff. Using MMQTTException did not work as I expected it to like OSError and RuntimeError exception handling.

#

It's a minor issue but one that did stop my online script in its tracks multiple times instead of automatically retrying its way around it. Probably my fault for using it incorrectly around the entire io.loop() instead of the individual def functions.

manic glacierBOT
brazen hatch
#

I mean, as a worst case scenario, could you not place a except: below all others if you want to always catch it?

#

Or if you wanna know what it was except Exception as err: print(str(err))

tulip sleet
midnight ember
#

Will probably do that, it didn't behave as I expected it would the same as OSError or RuntimeError would. I'm used to those with the requests library. Would be good to have error handling act the same for anything online/wifi related.

#

or maybe I'm just doing it wrong. will have to add a catch all at the bottom, thanks bill88t and danh. 👍

jaunty juniper
#

I don't know what the best exception hierarchy is, but I would say you want to catch a MQTTException when using the MQTT library ?

midnight ember
#

yeah after thinking about it if it fails inside the io.loop() I don't think it'll get to the bottom.

# 
try:
        io.loop()
    except (OSError, RuntimeError, MMQTTException) as e:
        print("MQTTException: \n", e)
        time.sleep(300)
        continue

    if (time.monotonic() - last) >= polling_rate:
        value = temperature * 1.8 + 32
        print("")
        print("Monotonic: ", time.monotonic())
        print("Monotonic Hours: ", time.monotonic()/60/60)
        print("Publishing {0} to DemoFeed.".format(value))
        io.publish("DemoFeed", value)
        last = time.monotonic()
#

vs

# 
try:
        io.loop()
        
        if (time.monotonic() - last) >= polling_rate:
            value = temperature * 1.8 + 32
            print("")
            print("Monotonic: ", time.monotonic())
            print("Monotonic Hours: ", time.monotonic()/60/60)
            print("Publishing {0} to DemoFeed.".format(value))
            io.publish("DemoFeed", value)
            last = time.monotonic()
            
    except (OSError, RuntimeError, Exception) as e:
        print("------------------------------Error: \n", e)
        time.sleep(300)
        continue
#

Most of the issues I have with it fail inside the io.loop() with an MMQTTException. Tried adding that to the except but it doesn't seem to be recognized as a valid error handler. Double checked the spelling, seems right.

#

It does recognize Exception in the bottom example but pretty sure it'll never get there if it fails inside io.loop()

tulip sleet
midnight ember
#

ah

#

which only uses OSError and RuntimeError which are not imported because they're built-in?

tulip sleet
midnight ember
#

🤦‍♂️ should i close that issue?

tulip sleet
#

I don't understand -- the weather station script doesn't use MQTT at all, is that right?

midnight ember
#

correct, uses adafruit_requests

#

I was expecting the error handling for mmqtt to be like adafruit_requests

#

seems like MMQTT has it's own built in error handling. i didn't realize error handling could be built into a library like that.

tulip sleet
#

the API of MiniMQTT is based (somewhat?) on some other libraries, but I don't know them at all, and don't know if they have unique exceptions. ... But your issue says you can't continue after the exception. That is a separate issue, unrelated to the class of the exception. In other words, is the exception recoverable or not? That's what you're asking for, is that right?

#

that isn't related to what the superclass is

#

just whether it's easy to catch

midnight ember
#

yes but I was using it wrong as you pointed out without the correct import

#

will likely work as intended now

oh, you mean you got a compile error?

[adafruit/circuitpython] New comment on issue #6765: microcontroller\.on\_next\_reset\(microcontroller\.RunMode\.BOOTLOADER\) not working on S3 TFT

Worth noting that I tried this NOT in REPL but in my script. Took about 2 hours to get out of it. You'd think that using python esptool to erase_flash would defeat it but it didn't. Only way out was to quickly load the QT Py S3 Factory Reset (even though I'm on a UM FeatherS3 because it's just too big to go through fast enough). Surprisingly the UM FeatherS3 is happy to live as a QT Py S3. Once the QT Py boot showed up I was able to reflash everything back as the UM FeatherS3.

I ran this on the Adafruit Feather RP2040 dvi and it seemed to work fine. I displayed a gif from desktop and an example turtle script without issue.

I was hoping I might stumble on a clue as to why the DVI+PicoW build is giving me trouble but other than learning that a color depth of 1 requires a widthxheight of 640x480 and a color depth of 8 requires 320x240 when creating a picodvi.framebuffer (either in C or python) I don't think I'm any closer.

Hi all, we are running into an issue where all USB comms on our 2040 suddenly die: the removable disk unmounts and both cdc interfaces disconnect. It appears the uC may still be running, although it is hard to confirm without serial comms.
The issue seems to be somewhat sporadic and difficult to reproduce.
In order to reconnect, we have to power cycle the uC.

Hardware: 2040 on a custom PCB, running 8.0.5

Is there any debugging tool you could recommend to trace the cause of this issue? Thanks!

Question - I am making a CircuitPython compatible board that I plan on selling.

I am currently creating the port for it. I see that there is a USB_VID and a USB_PID

I am not sure what I would put for those. Doing a vendor lookup, I see that Adafruit has their own VID, so I don't want to use that one.

Do I just omit/comment out? Do I put a random one?

I see that online, it costs several thousands to get a USB Vendor ID. This is just something I plan on selling a few of, so I really don't want to buy a Vendor ID

@open wren it should be possible. CircuitPython also can 'mount' a filesystem from a block device implemented in Python code. You can look at adafruit_sdcard from https://github.com/adafruit/Adafruit_CircuitPython_SD to see how that looks. I think the critical methods are readblocks, writeblocks and capacity. You'd substitute an implementation of these methods suitable for the W25 chip, probably using adafruit_bus_device as the abstraction for talking to an SPI bus.

I noticed the contributing page on circuitpython.org has got days that are off by 2-3 days from realtime. Investigating a bit I made a build of circuitpython-org locally from main and in the local version the days are 2 days "newer" i.e. a line showing Open 2 Days on circuitpython.org live site shows Open 4 Days on the local one.

It looks like the final action to build the site after fetching data failed to run fully the most recent attempt that it made: https://github.com/adafruit/circuitpython-org/actions/runs/4850291876/jobs/8643070977

Is this one of the actions that we can just use the re-run functionality with? Or does it need something different, or to just wait a day and see if it suceeds tomorrow.

if you added a pull-down of the same value, is the current drive enough to override the balanced pull-up/pull-down?

[adafruit/circuitpython] New comment on issue #7871: ESP32\-S2 A0 DAC truncates and reverses value below mid\-point

You could have a switchable pull-down by using a pin: external resistor you ground or not, or attach another input. But that's getting into the weeds.

I have no idea why they decided to add a pull-up on that pin and sacrifice the analog functionality -- it's weird.

If we assume that the pull-up resistor is impacting the DAC, adding an external resistance or source current to the pin would introduce other non-linearity effects and temperature issues. Designers take the DAC accuracy...

[adafruit/circuitpython] New comment on pull request #7862: Synthio envelope

Hi @jepler!
I finally got around to trying this out. Very cool! Much easier to change envelope rates based on incoming note playing, and we can now make some pretty expressive synths.

A few observations:

  • The synthio.Envelope is "global" to the synth, so the amplitude envelope of currently playing notes gets replaced by notes with a different envelope (e.g. play gentle, then play hard, hard notes' env replace gentle notes' env). It would be nice to have per-note envelope state, but ...

I also tested with the above code and it worked as expected. I did notice one peculiarity, If you set the framebuffer to any of the sizes greater than 320x240, pressing ctrl-D and then attempting to run the code with another framebuffer size greater than 320x240 but different than the one you just used caused a memory error. Pressing ctrl-D again, after getting the memory error and pasting in the same code that just gave you the error then succeeds.

I think that one part of it is the RMS level of a sum of a bunch of sine waves of different frequencies is less than the sum of their amplitudes, because half the time they cancel each other out; so that's why 12 notes sounds a lot lower volume than 1

#

when either one is "allowed" to get to +-32768 as the sum of all the waveforms

i.e. (sig1 + sig2 + sig3 +sig4)/4 and not thinking much harder than that about it

[adafruit/circuitpython] New comment on issue #5318: nRF: deep sleep increases power usage

@hiredman I don't suppose you are connecting to the REPL via bluetooth?

I've tried using uctypes to "manually" set up a pin alarm and deep sleep - and that seems to work really nicely, current consumption drops down to about 20uA as per my (fairly cheap) multimeter.

  pin_no = get_pin_no(hardware.BUTTON_A)
  if pin_no >= 32:
      gpio_base_addr = 0x50000300 
      pin_no %= 32
  else:
      gpio_base_addr = 0x50000000
  pin_cnf_addr = gpio_base_addr + 0x700 + pin_no * 4

[adafruit/circuitpython] New comment on issue #7926: CircuitPython HARD FAULTs crashes hard after several hours from async/await loops

I had a bit of a glitch overnight last night which killed my terminal sessions, so from yesterday's test runs all I know is that neither board crashed after about 13 hours.

I started the tests up again this morning but this time, I loaded the Lolin S2 mini firmware up on one of the boards first. The test program has been running again for about 13 hours. I'll check them again in the morning and hopefully at least one of them will have hard faulted.

#

Yes I've had this happen ever since the web flasher and web serial in chrome became a thing with every type of board. It's more likely to fail when it says paired next to it than when it doesn't. I have no idea what paired means (serial communication i think). It's not just the NRF, this definitely affects ESP boards as well.

#

You can use esptool in python to get around the issue of it locking down the serial bus quite easily with ESP32's using erase_flash then reflash with a bin. It's not as easy if you run into it with the NRF52840.

[adafruit/circuitpython] Issue opened: #7931 Wifi access point: setting subnet parameters

When starting a wifi access-point with this code:

import wifi
wifi.radio.start_ap(ssid=ssid, password=pw, channel=chn)

It will always use same local IP for the network it creates: 192.168.4.X
This prevents us from generating several networks with several boards.

Can you please allow setting the third part of the IP for a custom value?

[adafruit/circuitpython] New comment on issue #7926: CircuitPython HARD FAULTs crashes hard after several hours from async/await loops

Had a HARD_FAULT again last night.

The timestamp is odd. Safemode got hit at 3:33AM. Then it rebooted into normal mode which should be about 10 seconds later, but the clock says 3:27AM. I do the RTC lookup when booting in normal mode, so it just makes me think the clock runs fast on the ESP32. Is it possible a fast clock throws stuff off over time and that's what causes a hard fault?

From safemode.py. Kill switch off. 2023-05-04 03:33:58, supervisor.RunReason.STARTUP, microcontrol...

@slender iron [up early?] quick gut check question -- I have ported the cpython library for reading wave files to CP (nearly trivial). it seems useful for reading single-cycle waveforms for synthio. should i package it as an adafruit circuitpython library, or put it in the community bundle? I anticipate it'd be used in a synthio guide which tends to make me think adafruit.

[adafruit/circuitpython] New comment on issue #7926: CircuitPython HARD FAULTs crashes hard after several hours from async/await loops

No luck for me, 25 hours, 2 boards, 30 asyncio loops and no faults yet. I'll keep them running but I'm wondering if it's something with the specific board. Do you have just one of the Lolin boards?

I've gone ahead and ordered one which should be here in about 10 days but I also seem to remember that there was an issue with different manufacturers of these boards using different parts that behaved differently. Hopefully I've just been lucky and I'll be able to reproduce this on one of these...

I have tested this on 2 different Lolin S2 Mini's and same issue, but I

[adafruit/circuitpython] New comment on issue #7926: CircuitPython HARD FAULTs crashes hard after several hours from async/await loops

I do have the display regurgitating the standard output, so code would be
executing in those display classes. I just commented out that part of the
code so I'm ONLY testing the async tasks. If this doesn't crash on me then
it would have to be the display causing this. If it does crash, one other
idea is that I am using the Web Workflow to see the serial output. Perhaps
it's the Wifi classes causing it.

As for powering the board, I'm just using a normal USB-C wall wart for a
Raspberry Pi that...

The adafruit_wiznet5k_wsgiserver.py module in the adafruit_wiznet5k Ethernet driver implements a WSGIServer class. This class relies on a mixture of calls to deprecated, non-standard socket.socket methods and direct calls to the hardware via WIZNET5K methods. It is difficult to maintain. Rather than expend a lot of effort on refactoring this module to use only standard socket.socket calls, does the adafruit_httpserver provide the same functionality as adafruit_wiznet5k_wsgiserver.py, could it be used instead?

yeah I implemented readline() because the point was to make it work the other way too, so that native wifi sockets could be used with libraries that were written for ESP32SPI (originally it was written for my uwebsockets port, which assumes native wifi)

# slender iron so you need `(i,)`

brilliant, thank you. I was trying to avoid changing more of the main i2c driver logging code, i.e. I can get it to work changing "{}".format to "%s" which allows the code to work, but changes one log method in connection.py and I was curious why it was necessary for adafruit logging but not python logging.

@willow totem it can sometimes be useful to split lines like those up to make them easier to read, too. i.e.
