yeah a used prius goes for the same price as a new prius, because you're buying "not waiting 6 months"

we also got a 2013 very low mileage Corolla a year later, and those prices are also higher

Interesting new wrinkle in the host workflow for me. Drag and Dropping the video file to the upload box on YT was not working. I was getting "file invalid" type errors. It seems to work okay by using the Browse button instead of drag and drop though.

#

this is the first time actually uploading from my new computer I think. I switched primary browsers to firefox at the same time though so lots of variables. I can remember to use the button.

I try to manage expectation about this board and avoid short circuit or broken sensor. 1) I almost burned myself by mixing LOLIN I2C JST SH accessories and Adafruit QTPy, reverse way, I could have destroyed an Adafruit sensor by connecting it to Lolin S2 Pico. 2) The screen does not work as expected for a build-in screen, DISPLAY is not defined when you import board

https://github.com/jepler/circuitpython/commit/e635457a32b1cc3b4b611808fcdd16951d12f99c @tulip sleet @slender iron and anyone else interested, this is a non-booting sketch of what I'm thinking when it comes to revamping supervisor allocation.

Key is, whenever gc is up, supervisor allocations are also 'regular' allocations, so making a supervisor allocation is just gc_alloc + some slight additional bookkeeping. A freed supervisor allocation becomes gc collectable. supervisor allocation moves are done when gc is initialized.

I didn't try to debug anything, only got it to where it'd build for pico w.

#

@tulip sleet I'll put that aside and look at the problem you saw with getenv

@tulip sleet at 8.0.0-beta.5-27-g1b15985783 pico w wireless works, including workflow. hum. are either your ssid or password close to the size limit?

[adafruit/circuitpython] Issue opened: #7334 revamp supervisor allocation API

I have a sketch at https://github.com/jepler/circuitpython/commit/e635457a32b1cc3b4b611808fcdd16951d12f99c but it doesn't boot.

The idea is to do more to leverage the gc allocator to make the supervisor allocator work.

See the commit message for more details.

Entered as an issue at @tannewt 's request

I don't plan to work on this until after 8 is out, but it was in my brain and I had to do at least this much of it.

slender iron
#

@tulip sleet @onyx hinge any thoughts about exposing pin number to python? I'd need it to patch a ulp program

#

could do as .pin_number or int(pin) I think

#

or I could add a ULP function to do it

tulip sleet
#

is it RTC_GPIO_n or GPIO_n or is it lower level than that?

slender iron
#

RTC_GPIO_n

#

(which is a subset of GPIO_n)

#

0 - 21

tulip sleet
#

lemme look at the doc

slender iron
#

afaik it isn't expose to python yet

tulip sleet
#

on ESP32-S2, GPIO2 == RTC_GPIO2, but on ESP32, GPIO32 == RTC_GPIO_9, etc

slender iron
#

kk, I only looked at S3 and S2

#

I'll just add a module level function to espulp

tulip sleet
#

that was the craziness I mentioned in our video talk

slender iron
#

espulp doesn't target esp32 now anyway

onyx hinge
#

I think int(pin) is not great, I'd do .pin_number or .number.

slender iron
#

I'm just going to do espulp.get_rtc_gpio_number()

#

that way it won't leak to other ports

midnight ember
#

@slender iron just sitting down to listen to the meeting. Have you considered a dedicated NAS, synology is a very popular brand.

midnight ember
#

Though if the PC would have just worked probably wouldn't even be bringing it up. Sucks to hear the PC woes.

slender iron
#

yup, frustrating for sure

midnight ember
#

Have you tried unplugging it, waiting a couple minutes, and plugging it back in? Sounds basic but during a lightning storm if there's an electricity loss sometimes my PC's actually refuse to power back on unless I do that.

#

it trips the circuit protection in the PSU

slender iron
#

I didn't unplug, just flipped the psu switch

midnight ember
#

Honestly don't know if there's a difference, I always unplug just to make sure the caps drain fully.

#

Make sure you got the motherboard headers for the power switch correct? If you get them backwards it might turn on and never again. The motherboard power switch pins wait for a 12V blip of a toggle switch.

#

Also make sure the power button isn't stuck... that actually happened to me with my current PC case. I had to dremel part of the power button so it would slide smoothly.

#

a way around PC power buttons it to jump the power sw headers with a screwdriver or jumper directly.

#

hopefully it's something simple that doesn't require parts replacement 🤞 wish you good luck.

[adafruit/circuitpython] New comment on pull request #7321: Dotenv becomes toml

Thanks for 3620d14. Now my Metro ESP32-S2 is coming up in web workflow. I am still have odd crashes. Now I am getting HardFault_Handler safe mode when using the file browser to download a file that is not known to be a text file:

I am not having this problem with the tip of main right now.

#

@onyx hinge I edited the report above -- I am seeing similar issue on Pico W

#

this seems like it might be a storage and/or gc issue

manic glacierBOT
onyx hinge

@tulip sleet this is wrong before and after

     } else {
-        _send_str(socket, "Content-Type: application/octet-stream\r\n");
+        _send_strs(socket, "Content-Type:", "application/octet-stream\r\n");
     }
tulip sleet
#

because of the missing NULL, right?

onyx hinge
#

right

#

I pushed a fix and enabled a gcc attribute so it would have been a compile-time diagnostic.

tulip sleet
onyx hinge
#

it's specifically the pico w that is not consistently coming up now?

tulip sleet
#

yes

onyx hinge
#

re-plugging or resetting?

tulip sleet
#

I do a UF2 load and CIRCUITPY does not appear. Plugging it in and unplugging several times and it eventually shows up, but not necessarily on the first power cycle

onyx hinge
#

I think I just had it happen on trial 6 of re-plugging

tulip sleet
#

aha

#

back later -- thanks!

#

i am unplugging at the USB-A end; easier on the fingers!

onyx hinge
#

yes

#

same here

#

I notice common_hal_wifi_radio_connect can throw, which would go crashy-crashy during wifi workflow startup, pursuing that angle..

#

doesn't look like anything that should happen though

jaunty juniper
#

you could get some magnetic USB plugs for testing plugging/unplugging, I think Adafruit has some 😉

onyx hinge
#

the cables weren't in stock last time I looked but yeah I have some of those

#

@tulip sleet this affected rebooting from the bootloader back to circuitpython, so it's different than the "delay 1s at startup" problem, right? because that was a cold boot only scenario as I understood it.

tulip sleet
onyx hinge
#

most failures return error codes, but a few failures don't

# 
 wifi_radio_error_t common_hal_wifi_radio_connect(wifi_radio_obj_t *self, uint8_t *ssid, size_t ssid_len, uint8_t *password, size_t password_len, uint8_t channel, mp_float_t timeout, uint8_t *bssid, size_t bssid_len) {
     if (!common_hal_wifi_radio_get_enabled(self)) {
-        mp_raise_RuntimeError(translate("wifi is not enabled"));
+        return WIFI_RADIO_ERROR_UNSPECIFIED;
     }
#

enabled is just a flag and web_workflow calls enable() so it can't happen

# 
        mp_raise_RuntimeError(translate("Wifi is in access point mode."));
    }

```then there's this one, which is querying the device I think
#

but how could the AP be up at that point

tulip sleet
#

I changed some STM PWMOut code (I think that was it) to only return error codes, so I could call it outside the VM safely (maybe in LED status code or something). Or maybe I was just trying to be consistent

``` this is a nonsense fix
#

but it's made me succeed 15/15 tries, when I was getting >1/10 failures before. but never 50/50 failures like you seemed to be describing.

tulip sleet
#

I was getting 4/5 failures

onyx hinge
#

I certainly wasn't getting that

tulip sleet
#

it's confusing; I will try again with tip of main. I think this is timing or uninitialized memory or floating pins or something

#

are the CYW pins all firmly set to something before startup is attempted?

onyx hinge
#

that's an unanswerable question.

#

you mean the HW interfacing pins between Pico & CYW or do you mean the CYW's GPIOs, which is what the status LED above is?

tulip sleet
#

hw itnerface pins; the pins you use tot talk to it

#

CS, etc

onyx hinge
#

that is all managed in the sdk

#

I assume it's right

# 
    never_reset_pin_number(24);
    never_reset_pin_number(25);
    never_reset_pin_number(29);
``` I never-reset them and that's all I ever do
#

reset_all_pins is called before this

tulip sleet
#

we don't accidently reset those pins ... just what I was going to ask, but on hard reset, are the never_reset's in effect? The espressif code has "reset forbidden" pins so the SPI flash pins etc are not disturbed

#

it's just a hypothesis

onyx hinge
#

if this is really the initialization problem then why did it only appear for you today?

tulip sleet
#

no idea; just a timing difference, maybe. I did not try my Pico W with web workflow before

#

but... I was having trouble before that, so never mind, I think that's not it. I am going to re-test the ESP32-S2 and try the BLE workflow name setting and get the PR merged. Then I will come back to testing this more systematically, maybe with a bisect

onyx hinge
#

at power on GPIO pull down is enabled. However, gpio reset (circuitpython reset_pin_number) turns pull down enable off. So it could allow an interface pin to float up

#

OK pushed those things

crimson ferry
#

you two are talking about behavior due to post-beta.5 changes, right, rather than generic beta.5 picow?

tulip sleet
#

it appears so

crimson ferry
#

don't know if it's relevant at all, but sockets are broken in beta.5 on picow if web workflow is enabled (you may have seen the issue)

onyx hinge
#

I wonder if #define MEM_SIZE 4000 this needs to be increased (in ports/raspberrypi/lwip_inc/lwipopts.h)

#

the repeated retries stuff in requests conceals the "real exception", whatever it is.

#

and it's written in a way that exception chaining doesn't help 😭

tulip sleet
#

fyi, sorry, CPB build is not working even without settings.toml

onyx hinge
#

OK

#

good to know

tulip sleet
#

maybe we should leave this all for the morning

onyx hinge
#

I pushed the cyw43 initialization changes at least

tulip sleet
#

tip of main for CPB is working

onyx hinge
#

mp_obj_t ble_name = common_hal_os_getenv("CIRCUITPY_BLE_NAME", mp_const_none); yeah this is suspicious, I don't think the heap is up so the object variant can't be used

tulip sleet
#

it does quick blue flashes twice and then nothing

onyx hinge

probably needs something like```diff

that means workflow comes up but with default name?

presumably

As the Olimex ESP32-POE board is currently not listed on the CircuitPython downloads page I assume this is not supported so far:

Hello Dan,

first thanks a lot for your reply quick reply which is much appreciated!

I would be happy to help with that and I do think that I could get it to work in WiFi mode as this board is based on the regular ESP32 chip - so copying the configuration from one of the already supported boards should work.

edgy flax

ok, so on a pi pico does 'board' not return SCL and SCA?
from board import SCL, SDA
Traceback (most recent call last):
File "code.py", line 7, in <module>
ImportError: cannot import name SCL

amber sundial
#

I don't see them defined seperately in pins.c

tulip sleet
#

There is more than one set of "defaults"

onyx hinge
#

@edgy flax the silkscreen of the pico does not designate a default I2C bus so CircuitPython does not either. However, in 8.0 beta we do designate "board.STEMMA_I2C" which is the port that is compatible with the Adafruit "cowbell" add-on.

amber sundial
tulip sleet
amber sundial
#

anyways these two pins (and a combination of others) should work?

tulip sleet
#

so pick any two that are I2C0, or any two that are I2C1

#

you could use GP5 and GP4, you could also use GP5 and GP0

#

but that's more confusing

#

they don't have to be physically adjacent

amber sundial
#

@tulip sleet can I ask you about something else .. I have a problem at the moment where when I use a compiled uf2 from the RP pico SDK, my program doesn't boot on a power cycle. With a uf2 from circuitpython it does always work (hooray!!); where can I look up which flags you set for the pico SDK?

I already found this one

#define PICO_XOSC_STARTUP_DELAY_MULTIPLIER 64

and are you also using this one?

#define PICO_DEFAULT_BOOT_STAGE2 boot2_generic_03h

In circuitpython I use EXTERNAL_FLASH_DEVICES = "W25Q64JVxQ", I have that one on my board.

#

So this isn't strictly a Circuit Python problem, more a problem that Circuit Python has already solved ❤️

#

The question would be, where can I look up what EXTERNAL_FLASH_DEVICES does

tulip sleet
#

have you set the multiplier already?

amber sundial
#

yes! building my board in circuit python works reliably with that flag

#

and it also reboots reliably

tulip sleet
#

so you need to also set that flag in the UF2 you are building in the pico-sdk. We have that set in our board definitions that were added to pico-sdk. lemme find that

#

i guess we are using the GENERIC flag in those .h files, but not in CircuitPython

amber sundial
tulip sleet
# 
// Use slower generic flash access

I'll have to say it was charmingly easy to set this up in Circuit Python

#

thanks - we want to make it easy for us, and that transfers over 🙂

#

@tulip sleet yes it seems like if I change the BLE name I have to forget & re-pair but that's probably expected

#

but I can set a custom name in settings.toml and connect to it

#

just pushed the fix, which was slightly different than the non-working patch I shared last night

#

(name_len was never being set anymore)

tulip sleet
#

i am having trouble getting Glider to connect again after changing from 7.3.3 to 8.0.0-beta.5. I forgot everything and even turned Bluetooth and and off on the iPhone. However, iOS caches BLE stuff very agressively. I may try power-cycling the phone.

#

i could also try with an Android tablet

#

ah, I had to clear bonding info yet again on the CPB

onyx hinge
#

I guess I did that too at somewhere along the line

#

CIRCUITPY_BLE_NAME="0123456789012345678901234567891" this works (31 chars) but 32 chars gets me the name "nRF5x"

#

which is weird, it should get default_ble_name!

tulip sleet
#

not checking return code from that properly?

#

might be deep in _bleio

tulip sleet
amber sundial
tulip sleet
amber sundial
#

yes and also most of the actual layout around the chip

#

ah hang on we used that from the pico documentation

tulip sleet
#

so 18 pF caps + their crystal?

amber sundial
#

there was a Kicad file and a hardware reference PDF

#

but we made a four layer board

#

my wife does the PCB and engineering so I don't have it from the top of my head

tulip sleet
#

the cap choice is described in one of the PDF's. Ah, interesting. We did a lot of experimenting because we originally we thought maybe we chose the caps wrong due to a typo, but replacing them did not fix the slow xosc startup. We know what our board yield was; we don't know what RPI's was; their samples didn't show this problem but maybe they are QA-ing those out

amber sundial
#

she says she calculated the caps from the formula in the reference PDF

edgy flax
tulip sleet
#

and you still had the problem, at least on some samples ... interesting

amber sundial
#

yes we only have 5 prototypes but they do behave differently

#

Circuit Python works reliably on all 5 so that configuration seems to work for us

onyx hinge
#

@tulip sleet OK I pushed another fix related to maximum buffer length

tulip sleet
#

lengthening the xosc startup seems very reliable

they might consider changing the default, I guess

@slender iron getenv_str and getenv_int could be moved to __init__.c (making os_getenv_buf_terminated part of the non-static API) but common_hal_os_getenv has to be in getenv.c so it can be linked with the unix coverage build without replacing the rest of 'their' OS module, which is a big undertaking we do not need right now. I like getting rid of the extra file, but I'd rather not do any of those other things right now.

(and honestly getenv_str and getenv_int would be nice to directly test in the testsuite; those are the code paths that are all about static buffers)

that's fine. just document it somewhere

hi,

Good to know. I'll be careful of this in the future.

Once I changed the source file names there were no import name collisions.

The problem with the "featherwing" is there is no such thing as "ls -R", the whole OS seems
to be a python interpreter.

Too bad import doesn't accept a debug flag that prints its search path - but

I'm guessing for that to work, import would have to become a function, like print.

Sorry, I just meant you could do ls -R /media/yourname/CIRCUITPY on the host computer (assuming it was Linux).

I think you would find the same issue with regular Python. It also uses sys.path to find things. Its sys.path does not include /lib, of course, but it does include various library locations. If you replaced only some of the files in a particular library, I think it would have the same import troubles.

@slender iron I think I've got it done! Except, there is one issue. I attempted to playback a sine wave, and it skips. This is because Python can't generate the sine wave fast enough (I'm using a QT Py RP2040), so the buffer is emptying (and then playing back silence) while the next portion is generating. I thought this might happen, and I may be able to work around it, but even if I can get a sine wave playing, more complex waveforms that take even longer to generate could still have issues.

I'm not giving up though! I'm going to see if a square wave (or triangle or sawtooth...) will work, as they don't require an expensive trig function. If those work, a lookup table for sine waves could be a valid solution. Alternatively, I could do it all in C and add yet another module for synth generation (which I was already planning to do eventually anyway). Regardless, there is definitely going to be some limit to how much complexity any given processor can handle before it takes too long to generate the audio samples.

Anyhow, if anyone is interested, the code is on my CircuitPython fork: https://github.com/Rybec/circuitpython The new module is audiostream. I'm going to do a bit more testing before putting in a pull request.

@slender iron I have some potential information on the issue with speaker noise happening when the board automatically resets on filesystem writes. During audio playback using my new class, the print function causes audio noise when the board is connected to a serial console. I'm not 100% sure these are connected, but I suspect they are. My class does not interact with the serial system at all, so it's unlikely that it's a bug there. I haven't tested this with the existing RawSample or WaveFile class, but I suspect the same noise would happen when communicating with the serial console while they are playing.

#

Alright, I've verified that the same thing happens during playback with RawSample. Each time something is printed to the serial console, garbage is output on the audio. This only happens when the device is connected to the serial console though. When there is no connection, it does not happen. (The noise during automatic reset, however, does happen even when not connected to the serial console.)

stuck elbow
#

crosstalk between the traces?

serene token
#

Possibly. This project is using the QT Py RP2040, and I haven't tested it on any other board. That said, the auto reset thing produced the noise on A0, A1, and A2 equally. Since I tested that, I soldered the speaker to A0, so I can't really test other pins anymore. (If my oscilloscope was out of storage... I don't have room for it right now though.)

#

It's not a huge deal for this project, as I don't need to use serial for the end product, and it doesn't produce noise on manual resets or power on/off. It's mostly just an annoyance. If someone did need to use serial and audio at the same time though...

blissful pollen
serene token
#

@blissful pollen Audio uses DMA, according to the source code in the part I was working on. It's possible that the serial and automatic reset are preventing the DMA from being updated on time when it gets to the end of buffer, either reading past the end a bit or causing just enough delay between updates to produce brief garbage output. It would only take a byte or two delay to turn smooth audio into something very rough.

Hello, for private functions that will be compiled by mpy-cross, is it better to use doc strings? e.g.

    def _next_retry_time(self, *, interval: int = 4) -> int:
        """Calculate a retry stop time.

        The interval is calculated as an exponential fallback with a random variation to
        prevent DHCP packet collisions. This timeout is intended to be compared with
        time.monotonic(). Uses self._retries as the exponent, and increments this value
        each time it is called.

        :param int interval: The base retry interval in seconds. Defaults to 4 as per the
            DHCP standard for Ethernet connections.

        :returns int: The timeout in time.monotonic() seconds.

        :raises ValueError: If the calculated interval is < 1 second.
        """
        ...

Or should I use comments? e.g.

    def _next_retry_time(self, *, interval: int = 4) -> int:
        """Calculate a retry stop time."""

        # The interval is calculated as an exponential fallback with a random variation to
        # prevent DHCP packet collisions. This timeout is intended to be compared with
        # time.monotonic(). Uses self._retries as the exponent, and increments this value
        # each time it is called.

        # :param int interval: The base retry interval in seconds. Defaults to 4 as per the

        # :returns int: The timeout in time.monotonic() seconds.

        # :raises ValueError: If the calculated interval is < 1 second.

I'm wondering whether mpy-cross throws away comments, saving space?

[adafruit/circuitpython] Issue opened: #7357 Fix error when trying to set cpu\.frequency but not supported

According to this forum post the error is "Attribute Error:
'Processor' object has no attribute 'frequency'" It should instead say it isn't settable. I suspect we need to remove the setter when setting isn't possible. The code now returns a NotImplementedException that is being caught internally and producing the error seen. So conditionalize this:

@tulip sleet does the notimplementederror actually make it to the user?

tulip sleet
#

Maybe I will take away that SETTABLE flag, and add a weak common_hal set_frequency

slender iron

I was guessing

#

🙂

tulip sleet

or we'll make CIRCUITPY_SETTABLE_PROCESSOR_FREQUENCY have a useful default value. It's set to 0 or 1 per board, which I think is too many places. Should be mostly per prot.

manic glacierBOT
tulip sleet
# slender iron I was guessing

it looks like in py/runtime.c, mp_store_attr() gets a return value from the attempted call, even if it threw an exception, and turns that into a "has no attribute" error. This looks like it would be true for any property that threw an exception. I will see if it's true for reading attributes as well as writing, but I'm confused, because this would break all kinds of property error checking, and I don't see that right now. (e.g. setting a bad value in, say busio.UART

# onyx hinge NotImplemented in particular? weird!

it's even more weird. I had a random build on a Metro M4, and got this:

something to do with built in types? ```class X:
@property
def p(self): return 1

@p.setter 
def p(self, _): raise NotImplementedError()

x = X()
x.p = 1

tulip sleet
#

I then rebuilt with ValueError instead of NotImplementedError, and got ValueError: frequency is read-only for this board, as I would expect. Then I rebuilt back to NotImplementedError, and got NotImplementedError: frequency is read-only for this board.

#

that is, it was inconsistent. So maybe it's reading trash on the stack or something.

#

sometimes zero, maybe sometimes not?? I haven't yet been able to reproduce the "random build" behavior. It was a leftover build from debugging the other AttributeError DEBUG=1 issue

#

I rebuilt with DEBUG=1 but could not reproduce

onyx hinge
#

that feels like it could be a clue about the crashing error

tulip sleet
#

yes, maybe they are all related; it's rather odd syncrony

#

there is no special handling of NotImplementedError in circuitpython/py/*

agree, based on a quick check. same for RuntimeError which NotImplementedError inherits

brazen hatch
#

Anybody got any hints on working with the mpy-cross logic?

tulip sleet
#

@brazen hatch are the built .mpy's in the bundle or the library release on github defective, or only when you compile with mpy-cross by hand?

#

i don't see any optimization settings in circuitpython-build-tools, but I may be looking in the wrong place.

brazen hatch
#

-O0 is fine

tulip sleet
#

i understand, but are you doing that compiling or is the bundle version being built with -O1 or greater?

#

i.e. is the bundle version of this library fine?

brazen hatch
#

I am the one doing it, the bundles are fine

#

the are most certainly not using optimisation settings

tulip sleet
#

ok good, I wanted to know if this was urgent. thanks for discovering this. We never use these settings, and will look at whether micropython has any reported issues on this

brazen hatch
#

well I have been using -O3 with my whole project and never seen issues

#

so its prolly something very specific causing this

jaunty juniper
#

what does it even do ?

tulip sleet
#

do you see significant space savings?

jaunty juniper
#

is there any documentation of the optimizations ?

brazen hatch
#

complete borkage, basically no variables are being updated it so seems

brazen hatch
#

and my stuff has no issue with it

brazen hatch
#

something is really wrong with it

tulip sleet
brazen hatch
#

it checks out on -O3 you get Line 1 on every error

#

but we struggling on -O1 here

tulip sleet
#

but only that library; others are ok, you say

#

there are tools to examine the .mpy code. I am not seeing any error reports in the micropython repo.

#

we will take a look, not immediately, but may pass the buck to micropython if we discover a problem.

manic glacierBOT
brazen hatch
#

I will give it a try too, and pass you whatever findings

manic glacierBOT
onyx hinge
#

@brazen hatch you're talking about when you run mpy-cross -O#, not about the compiler flags when building the mpy-cross program itself, right?

#

-O3 does deliberately disable line numbers, to save space.

#

-O1 or greater controls whether __debug__ is a true constant or a false constant.

#

based on source searching, I don't see any other intentional changes due to setting optimization levels in the mpy-cross commandline.

adafruit_wiznet5k uses assert a bunch

onyx hinge
#

OK, asserts are disabled too. And wiznet5k uses assert in a way that is .. not entirely appropriate

Hi, I have setup a temperature sensor MCP9808 connected to a Feather M0 Express that will monitor a room for 2 weeks (with a host gathering the data and putting that in an SQLlight database) all that following this great guide: https://learn.adafruit.com/diy-trinkey-no-solder-air-quality-monitor/circuitpython

However, I feel I need a guide or advice on how to make reliable piece of hardware/software to work unattended for 2 weeks. Some ideas/questions (none that I have implemented):

  • Use watchdog (poor choice, there is no CP support for the M0).
  • Use try to catch exception and force a reset.
  • Monitor the heap/memory space and write defensively using prealocated buffer.
  • For a restart every ??? day.
  • Do not trust the precision of monotonic over long period and use ad-hoc function for time comparison (I think @onyx hinge made some work on that?

# thorny jay Hi, I have setup a temperature sensor MCP9808 connected to a Feather M0 Express ...

Right now, for me it is too late as I will lose access to this place for 2 weeks, and I did not bring the right MCU for the job (watchdog), nor want to make last minutes change to the code... but I feel there is maybe a place for a learn guide or gathering experience on the best practice for "high availability CP". A bit like we did for memory issue and how to optimize your code.
I know CP is not targeted at that, nor at security, but having things that run for weeks without help would be great too.

#

philosophical question re:libraries... Board helper libraries like the ones using PortalBase tend to be all-encompassing.

#

But should we try to keep lower-level driver-type libraries smaller and more minimal? Example: do we really need NTP in WIZnet5k library, or should WIZnet be simply a physical/link-layer/IP-layer library, and other code or libraries can build on that? Other examples in WIZnet, EPS32SPI, and the WSGI servers that are scattered around too.

brazen hatch
onyx hinge
#

there are apparently hundreds of other uses of assert across the libraries!

#

for example rfm9x/adafruit_rfm9x.py:713:9: assert 0 < len(data) <= 252

#

at least 100 in files not named *test*

brazen hatch
#

honestly before today I didn't even know of assert

onyx hinge
#

some of them, like maybe that rfm9x example, are the kind of asserts you'd want to leave out of a -O'd mpy file so they really need human review

#

should this one be an assertion or an exception? (adafruit_atecc) no idea. ```py
self._get_response(status)
assert status[0] == 0x00, "Error during sha_start."

@slender iron I have CircuitPython 2023 graphics for you. To add to your blog post.

onyx hinge
#

a motivated person would run the script, then using a tool like git-gui make a judgement call and either commit or revert each one. erring on the side of transforming, because it would be bad to lose an important error check.

#

assert is really an archaic C-ish thing imo, not surprised if anyone's not familiar with it.

@tulip sleet What ended up happening with the .toml guide updates?

tulip sleet
#

not merged yet, so we didn't do anything. Scott's coproc PR may or may not get in by tomw. In either case, I will make a beta.6 tomw that includes settings.toml.

@tulip sleet Ok, I talked to Liz. We figured out a plan, which I can explain when you're around. We'll be putting together the canonical page for you to mirror, and then there's a blurb on every applicable code page that will need to be updated, and we will compile a list of links for you. Liz and I will both be around tomorrow to answer questions, and Liz offered to help update guides if you wanted assistance.

NTP shouldn't be redone unless you can't do it with sockets from the device.

crimson ferry
#

NTP is already in the WIZnet library (as is a WSGI server), but there's a PR to fix a bug. UDP sockets work fine on WIZnet. Similar issues with ESP32SPI.

#

We almost need a channel here for libraries for development and longer-term stuff... like the socket vs. socket+interface conundrum between native and WIZ/ESP

idle owl

@tulip sleet Do you want to vid for a bit to go through the guide update plan? We have a document, so it's not bonkers to try to remember it all. Also Liz can help, and I'll be around as well tomorrow to help out as well. I don't know what your timeline is, but I likely won't be around until noon or later, so if you want to get started before that, it's better to chat about it today.

What's the best way on espressif to extinguish an LED that would ordinarily start up floating at half-brightness in board.c while retaining it for later use at the circuitpython code level? Just something in reset_board()?

[adafruit/circuitpython] New comment on issue #7333: raspberrypi 8\.0\.0\-beta\.5 socket exceptions when web workflow is enabled

I just tested this with latest S3
Adafruit CircuitPython 8.0.0-beta.5-22-ge9f032f46 on 2022-12-20; Raspberry Pi Pico W with rp2040
and .env converted to settings.toml.

This works now with web workflow enabled. (Requests is still often getting an OSError: 32 on the first, hidden, try, but the internal retry is successful.)

Does anyone know what was broken in beta.5 (it used to work in beta.4), and what fixed it?

crimson ferry
#

Do we have a preference for single vs. double quotes in setings.toml ? All the readthedocs use double (but no explicit mention that I could find), but the web workflow Welcome page uses single.

jaunty juniper
#

ah that needs to be updated then, prefer double quotes

tulip sleet
#

I think it has to be double quotes

tulip sleet
crimson ferry
#

Any thoughts of supporting a more complex type so we could essentially have lists or dicts? I want a list of potential servers in settings.toml that code could iterate over, but for now I'll just number them and know how many.

jaunty juniper
#

I wasn't sure, I remember seeing it mentioned, but it's not in the PR (about double quotes only)

jaunty juniper
crimson ferry
#

oh, good point, I can just parse a string

jaunty juniper
#

are there open issues relative to the web REPL ? I am seeing issues when pasting a line in it, namely it stops responding (without any javascript error)

crimson ferry
# 
>>> os.getenv("EMOJI")
'😹'
```😹
#

I don't know of open issues, but sometimes it eats the first character I type when first opened

#

by web REPL, do you mean web workflow serial console?

jaunty juniper
#

note that the serial REPL does too if it's in the "press any key" stage

#

yeah

crimson ferry
#

that could be it, but nothing is displayed in the upper pane of the web workflow window until after it eats the character ...doesn't always happen

#

I've seen the hanging too

#

is it just Macs that get the authentication dialog twice?

#

I've seen that in other contexts, so I assumed it was not a CP issue

spiral elk

esp32c3 is still really unstable in web workflow console.

[adafruit/circuitpython] New comment on issue #7326: mDNS find yields duplicate entries if another device is also find\-ing mDNS \(& other oddities\)

Opening a separate issue for this:

On raspberrypi, mDNS is not shutdown on reload, so m = mdns.Server(wifi.radio) gets RuntimeError: mDNS already initialized. Even on reset, with web workflow enabled, m = mdns.Server(wifi.radio) gets RuntimeError: mDNS already initialized.

[adafruit/circuitpython] New comment on pull request #7371: Initializing external flash SPI speed to SPI\_FLASH\_MAX\_BAUDRATE, instead of using driver default speed \(32MHz\), before probing JEDEC identifier\.

Two questions:

  1. Do your boards not use QSPI for the external flash?
  2. There is a serious problem with SPIM in battery-only operation: #5233. We encountered this, and disrecommend using SPIM3 under those circumstances. So I'm wondering whether your board might have the same issue. It's also possible to disable SPIM3 completely at compile time.

@tulip sleet I'm so happy you found an explicable reason for that crash!

[adafruit/circuitpython] New comment on pull request #7371: Initializing external flash SPI speed to SPI\_FLASH\_MAX\_BAUDRATE, instead of using driver default speed \(32MHz\), before probing JEDEC identifier\.
  1. No, our board uses standard SPI.
  2. I don't think this is the same issue. I noticed when probing sclk that the frequency was 32MHZ which caused problem when reading the JEDEC ID. Reducing the clock to Max clock makes it work again. The problem is that the SPI interface is initialized to the max frequency when creating the bus and only reduced after having detected what memory device is attached. Could that be the problem you are also seeing ? This would occur after power on and reset.

Is it possible on your board to have VBUS not powered? If so, does SPIM3 work for you in that circumstance?
It does work yes, I just retested to be sure. Both directly after power on and after reset running only on battery and VBUS totally disconnected. I have attached a schematic for your reference (The body diode on the mosfet is drawn backwards).
And this is with the fix I implemented to reduce the SPI speed during initial JEDEC probing. Otherwise it just hangs, waiting for a non FF by...

That is interesting -- thanks! Just to confirm: R5, the zero ohm jumper between VDD and VDDH is populated on your board? Your schematic is very similar to the Feather nRF52840.

I don't know why you don't see this SPIM3 problem. We saw it when trying to use SPIM3 much later, after CircuitPython starts, and as you can see from the Nordic DevZone complaints, other users are also having trouble when SPIM3 is used by user code.

That could be fun for anything with a display -- I just imagined a little handheld device using something like a Pico W, and some option buttons to pick from sets of categories and descriptors, and at the press of a button it makes the request and displays the results for you on your TFT or whatever

@tulip sleet Where are you with the release?

tulip sleet

it will finish building in about 20-30 minutes. I'm getting ready to publish the release notes after I update circuitpython.org (after the builds finish). Then I will do the settings.toml changes

I have no idea about settings.toml since i missed pretty much all related commits
So I will be seeing them for the first time

#

I plan on utillising it to its maximum for my project too

cuz I already had a config in root for defining core options like sd card pins, in case the user wanted to boot from an sdcard

in any case, the notes will receive lots of attention real soon

that moves the text down but there's still a lot of whitespace around the pic

I think that's fine.

That would work.

@candid sun I would suggest making the screenshot bigger, and use an arrow or something to point to the relevant part.

or add whitespace on the bottom to make it 4:3 in gimp or something

i mirrored the settings.toml setup page into some more of the guides, instead of providing an off-guide reference

@tidal kiln I updated all the guides to refer to settings.toml instead of .env, now that beta.6 is out. Your guide https://learn.adafruit.com/circuitpython-with-esp32-quick-start has a bunch of screenshots that use .env instead of settings.toml. I could try to re-create these, or do you want to? (Probably neither of us wants to.)

tidal kiln
#

@tulip sleet i can take care of it. i should catch up a bit on the .toml thing in general. so that'll force me to do that.

#

is the TLDR that .env is now settings.toml?

tulip sleet
#

yes, a rename, and really main thing is use double quotes instead of single quotes.

I think it might be more interesting to make it compatible with adafruit_httpserver and drop the wsgi server from the library, but maybe that's a longer term goal

question regarding settings.toml
are subtables going to be supported?

#

and is there going to be a ‘native way’ for updating settings.toml?

tulip sleet
#

this was designed to be a minimal settings thing that uses only a very small amount of C code.

#

all the toml libraries I've seen parse the whole file and present you with a dictionary of dictionaries or similar.

brazen hatch
#

Oh well, guess I am writing a circuitpy-specific toml module

#

I will make sure to keep it as tiny as possibly

tulip sleet
brazen hatch
#

Honestly adapting them to circuitpy memory standards is going to take longer than to rewrite

#

I want not a single byte of leaked ram

#

especially something I plan on calling constantly

#

it will fetch and save keys without loading the whole file

tulip sleet
#

saving keys of a different length without rewriting the whole file will be a bit tricky

brazen hatch
#

nah

#

remember, I have ported nano to cp

tulip sleet

the library will be welcome
