[delicate fractal]

years ago, a consortium (mostly lead by Cisco as I recall) released a packet-switched serial high-performance system bus. I3C reminds me of it. Wish I could remember the name.

[cinder wind]

still using the "master/slave" terminology, though. sigh

[spiral bough]

@open girder Does the I3C spec still use.... what @cinder wind said...

[ionic garnet]

it's really such an aweful term!

[lilac tusk]

My current just still uses that terminology. I push hard not to use it with my colleagues. Hoping my new embedded job I can make sure since the company is small enough, we can use more inclusive terminology

[slow spire]

@ionic garnet @cinder wind Perhaps they need a nudge to revise these 2010's docs

@lilac tusk Maybe hosting a brown back on the history of the terms, and stories about how they affect young makers. People remember stories.

Question:
Is it safe to have Neopixel strips as components that are regularly hot swapped to a project (attached using the magnetic connectors you have in the store) ?
Any risk of damaging the board pins ?

[humble tundra]

Question: I want to make a little project that can send data back and forth with a phone via NFC while being powered solely by NFC - are there any modules that will help with that, or would I have to make a custom circuit myself?

[brazen quail]

Does adafruit I/O work with Bluetooth ? (or just wifi ?)

[delicate fractal]

Oh! I had a question! In the factory footage, we often see a machine that is like a solder fountain. Is that a kind of wave solder system? What's that called?

[ionic garnet]

probably unwise. Neopixels are fragile beasts

[strange mantle]

FOr voice rec, it depends on the requirements and whether it needs to distinguish between speakers. It's a hard science problem without cloud or heavy metal (big computers). But it's come a long way and the CUDA cores or other turbocharger can help

[robust horizon]

how did I go all show without noticing the hair color! (not to mention S&T and the internal meeting today)

[ionic garnet]

Ifirst got involved in the mid-1990's in commercial use and as recently as working on Jibo in 2013 onward using modern algorithms and latest research/emerging tech

^^ speech rec

I really think if you must process onboard and it has any quality/accuracy requirement you want to look at something faster than a Pi. The Nvidia Jetson Nano dev kit is a pretty good platform and it is powerful with the CUDA GPU cores. It is used a lot in robotics and automotive use cases for many things involving a lot of math like vision, speach, AI, ...

https://developer.nvidia.com/embedded/jetson-nano-developer-kit

[slow spire]

I'd also search for speech recognition breakouts that support small custom vocabularies.

This USD $8 speech recognition breakout can support custom wake words and a 200-word vocab:

https://www.cnx-software.com/2022/04/15/8-lu-asr01-offline-speech-recognition-board-features-tw-asr-one-chip/

Might be LDO voltage regulator droop. Try powering the QTPy not by USB or battery, only feeding +3.3V to the 3V pin from a 3.3V strong supply

[unreal bay]

My hazy memory says certain ESP pins have access to different timers, tried switching pins?

[inner spade]

I’m a little late to the party. Pressing rewind multiple times now.

[cinder wind]

can't switch pins as it needs the DAC

[grand tusk]

TV Typewriter?

[cinder wind]

I mean, the jitter is very retro. very a e s t h e t i c

[whole arch]

Very cool project. How can we use the QT to play a looping video on a portable screen, like a 5" scree. A portable video player that only plays and loops one video.

[unreal bay]

to be fair the circuitpython page warns the larger boards can cope using the DAC for audio (video in our case) but the qtpy m0 and small boards cannot. https://learn.adafruit.com/adafruit-qt-py/circuitpython-analog-out

[still imp]

No boom

[cinder wind]

I think that page is talking about the fact that there isn't enough code space in CircuitPython on the M0-based boards to do audio playing

yay still jittery! maybe it's just a software problem then!

@smoky island Hi Tim and everyone present

Yes I hear you

[brazen grove]

hoi zame

[proper prawn]

All OK thank you!!

[brazen grove]

time sensor

it senses the flow of time

they use a quartz crystal as the sensing part

[proper prawn]

Tim is a flag to indicate a boot time situation

these globals are assigned

we could replace the rtc_present and similar flag to do the test 'if irtc s not None' etc

It works: in main() I replaced the if rtc_present by if rtc is not None and replaced if t_sensor_present by if tmp117 is not None. The program runs fine with this and disconnect and re-connect run fine

Tim you can also check the messages in REPL

[nova totem]

I never remember the colors and guess 🙂

[brazen quail]

Hola from 'rado ! :-D

[brazen grove]

it is an older code, but it checks out

[grand tusk]

Forest moon here we go.

[brazen grove]

day-month-year is an ISO standard

[proper prawn]

is set in line ...

look in the beginning of the script

[fallow fractal]

can you tell me how this works?

[brazen grove]

it was probably set at the factory

[fallow fractal]

like a pico?

[proper prawn]

time look at line 23 of the script. It is: 'default_dt = time.struct_time((2022, 5, 12, 18, 34, 0, 3, -1, -1))'

[fallow fractal]

ohhhh

ok I get it now

and you got this from adafruit?

[proper prawn]

yes

[brazen grove]

so once you ran it once, it set the time

[proper prawn]

I think that is why I intruduced the lStart flag to let the rtc set once

[hoary knoll]

Just wanted to say.... This RTC discussion is really helpful for the project I'm working on. GREAT STUFF

[proper prawn]

the need for setting the external rtc was what I was talking about yesterday...the idea I came up with to initialize the external rtc from an external file.

nr 4

sry nr 3

[brazen grove]

you have network, you can just hit your router and set the time from the response timestamp

[proper prawn]

how you 'hit your router'? Do you have an example? I'm interested

[brazen grove]

well, I would just do a http request on the gateway address, most routers have a web interface, and the http response has a timestamp in the header

[proper prawn]

ok, I'am going to try that

No, also the RTC

you have still 'if rtc_present' Change that into is rtc is not None

It will blank the labels

I another project I created a class where I set and get the globals

yes, inside the class I used a dictionary. I have to search for the files

[smoky island]

https://github.com/FoamyGuy/Adafruit_CircuitPython_DisplayIO_Layout/tree/paul_advanced_tablayout_pylint

[proper prawn]

OK

It is running

Flawlesly

Flaswlessly

typos all around

Tim a remark on the script you updated and asked me to run: because in main() (and elsewhere) not all flags for rtc and temp sensor were replaced by 'if ... is not None' main kept calling the reconnect functions

[brazen grove]

goodnight

[grand tusk]

Just center the background.

[proper prawn]

Tim I found a repo where I make use of a class 'myVars' (see: https://github.com/PaulskPt/M5Stack_DS3231_uRTC and within it in /flash/main.py and myVars.py

This is something similar but simpler. A class to get and set GPS datagram messages data

[grand tusk]

Why is it so slow to change the page?

[proper prawn]

Yep, calibration sure will make it better

[clever summit]

Hello Tim! 🇸🇪 👋

[proper prawn]

Tnx Tim!

[smoky island]

Just about to start up the stream this morning. Carrying on with the displayio interface. Maybe diving into some small core changes for it. Hang out here in the chat and follow along on Twitch:https://www.twitch.tv/foamyguy_twitch or YT: https://www.youtube.com/watch?v=YFclIALnBys

[proper prawn]

I hear4 you

[inner spade]

Does color button set the neopixel color independent of the on-off state?

Since on-off is a color selector, too.

In essence it selects BLACK

Just about did that and also wanted to include a rotational arg to touchscreen, but I couldn’t get cookiecutter to work in my environment.

Pounded my head against it for a couple of days, got some help and advice from experts, and finally decided to stop trying to share in that way.

Yes, pre-commit — the CircuitPython dev environment requirement was the issue.

I’ll toss it in as an issue and leave it up to an expert to grab it and run.

Having to learn Linux and git to make simple library contributions doesn’t work for a hardware-oriented mindset like mine.

On my Mac, I use GitHub desktop quite well.

With Atom.

[proper prawn]

Guys, I am leaving for the moment to take a nap. Last night I slept only about five hours. Have to charge my battery 🙂

[inner spade]

It’s worked well for the dozens of repos I hoard.

@proper prawn Enjoying your recent sensor and tab ideas. Inspirational.

I ran into some crazy nested interdependencies when using the command line to install a bunch of unknown tools from who-knows-where for why-do-I-need-this reasons. It became apparent that sharing CircuitPython code is way more complicated and prohibitive than the philosophy behind why CircuitPython itself was created. <philosophy mode off>

Well stated.

Use is easy. Simple contributions not so much.

[grand tusk]

[Blinka] What do I need to update?
AttributeError: 'TileGrid' object has no attribute 'width'

[inner spade]

When it scales, it has to duplicate pixels. It also seems to read and process the entire image, even the off-screen pixels.

[grand tusk]

pygame 2.1.2 (SDL 2.0.18, Python 3.9.10)

[inner spade]

Perhaps the image loader should stop processing the bitmap file when off-screen.

[grand tusk]

Guess I'll switch to the FunHouse. 🏚️

displayio performance is an enigma sometimes.

[inner spade]

Are there impacts to refreshing the screen when there are off-screen objects and scaled image bleed over?

[grand tusk]

Tab layout is working on the funhouse. 3 tabs, 3 buttons.

It's working! 🎉

[inner spade]

Thanks for the stream @smoky island

You're welcome

[inner spade]

@smoky island Just discovered that pre-loading font glyphs significantly speeds up displayio label text on the initial screen load; not noticeable on subsequent screen updates. This is on a PyPortal weather station with a bunch of labels. ```python
self.small_font = bitmap_font.load_font(small_font)
self.medium_font = bitmap_font.load_font(medium_font)
self.large_font = bitmap_font.load_font(large_font)

    # Glyph loading not required; speeds up initial screen loading significantly
    glyphs = b'0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-,.: '
    self.small_font.load_glyphs(glyphs)
    self.small_font.load_glyphs(('°',))  # a non-ascii character we need for sure
    self.medium_font.load_glyphs(glyphs)
    self.medium_font.load_glyphs(('°',))  # a non-ascii character we need for sure
    self.large_font.load_glyphs(glyphs)
    self.large_font.load_glyphs(('°',))  # a non-ascii character we need for sure

[proper prawn]

@inner spade great! I was looking for some characters like the degrees character or the Euro sign

[inner spade]

@proper prawn here are a few more for you. Don't know if they're in every font, though. ```python
å ∫ ç ∂ ´ ƒ © ˙ ˆ ∆ ˚ ¬ µ ˜ ø π œ ® ß † ¨ √ ∑ ≈ ¥ Ω
Å ı Ç Î ´ Ï © Ó ˆ Ô ˚ Ò Â ˜ Ø ∏ Œ ® Í † ¨ √ ∑ ≈ Á Ω
º ¡ ™ £ ¢ ∞ § ¶ • ª – ≠
‚ ⁄ € ‹ › fi fl ‡ ° · — ±

[proper prawn]

Thank you. I downloaded that weather station project. From it I copied the Arial 16 font. I added those line above but the execution of the script leads to 'Glyph not found: '°'' error.

and sure i changed the font loading to: font = bitmap_font.load_font("/fonts/Arial-16.bdf")

I think we should move our conversation to #help-with-circuitpython

[inner spade]

'Glyph not found: '°'' error in your message appears to have a single-quote syntax issue or is that just a Discord interpretation?

[proper prawn]

@inner spade I managed to print the chr(186) glyph

[inner spade]

Excellent!

[proper prawn]

No it was printed like that in the mu-editor REPL window

I had forgotten that I had to set the specific font in the label definition. Originally it was set for 'terminalio.FONT'

here is the current (working definition). The initial load is a bit slow.

It's bedtime here. Tnx for your helpful tips!

On the topic of multiple libraries with compatible APIs I'm a fan of this pattern so it's a one line change:

# import adafruit_rfm69 as radio_module
import adafruit_rfm9x as radio_module

[inner spade]

@smoky island Yes. For bdf files, the size is proportional to the glyph size (xy bit matrix) and number of displayable characters.

A bdf font file can be easily created/edited with a text editor.

Sometimes the font source and license info is contained in the first few lines of the font file itself.

Need a degree symbol in terminalio.font

[inner spade]

A library of Adafruit curated fonts would be extremely useful. Some licensed versions can be found here: https://github.com/adafruit/Adafruit_CircuitPython_Bitmap_Font/tree/main/examples/fonts

[inner spade]

Just looked at the source. Can’t for the life of me figure out how the glyphs were defined for the terminalio built-in font.

Oooo, I too am interested.

[cinder wind]

No lights yet, but I've just started playing with UDP in CircuitPython. @strong acorn made some great example code comparing normal CPython vs the various ways of doing it in CircuitPython: https://github.com/anecdata/Socket/tree/main/examples

[slow spire]

@haughty quiver The product description on https://www.adafruit.com/product/5325 mentions time of flight. Any idea how does that work, or if there are examples?

[haughty quiver]

No, I haven't tried that. That's a good question for Limor during AaE 🙂

I mean, I can throw it about 20 yards or so, takes about 4-5 seconds.

oh wait

that probably isn't useful...

Maybe the new five pin magnetic connect on adafruit could be used for the different ear caps, snap on different powered designs for work or play

Nice new breadboards! Breadboards totally wear out and become flakey. Think of them like consumables. But these look like they might last longer

[nova totem]

you dont have pin indentations in your fingers trying to get a board into a breadboard

[urban gale]

I like that the power rails aren't interrupted in the middle. I want crazy before I knew that was a thing

[desert orbit]

I've tried finding better breadboards over the years but I've never found one I really liked.. But this one looks great!

Definitely consumables usually 🙂

[cinder wind]

Question: will there be a half-size version? oh nevermind, probably so!

[open girder]

werkin on it!

[nova totem]

if you have a saw you can have 2 half sized ones

[cinder wind]

(I just had to toss out a few tiny breadboards I've had for a few years because some of holes had gotten so flakey to make me think my wiring was wrong)

[desert orbit]

Got the Tasmota IoT firmware working on the Feather ESP32 V2 board just the other day and submitted a 'template' page to their repo so people know how to get it working. Guess i'll need to set up another PR with info on the UART chip change. Glad that you were able to keep it in stock!

OMG, I totally forgot til now. Hi all!!!! A bit..... late.

[desert orbit]

Yay! Weighing things is fun 😄

Not many I2C strain gauge ADCs that aren't super pricey.

[hot frigate]

I would like 5 of these today please!

I'm tired of fighting with the HX711.

[upbeat coral]

Hmmm.... bed leveling project is coming back to forfront of projects.

[desert orbit]

The HX711 is a pain in the butt. 😓 Eventually got better results from my project after adding some shielding, seems sensitive to EMI/EMF

[upbeat coral]

Spose I could put the wifes fancy scales back together now.

[hot frigate]

For me the issues were the protocol. I want to try the PIO library from last from... can't remember sorry. I kept my wirelegths pretty short.

Measure how much catfood is in the bowl!

[upbeat coral]

Four of them and a summing network for big silos of products

[inner spade]

@open girder Strain gauges work nicely for measuring rotational torque, as well.

[desert orbit]

Without PIO its almost impossible to get deterministic results from higher-level code like CircuitPython, particularly on nrf and esp 😦

[desert orbit]

but if you have an RP2040 board definitely checkout the HX711 library I added to the Community Bundle awhile back

[hot frigate]

YES!

[cinder wind]

Question: Any more on the CH552 QT Py?

[desert orbit]

The HX711 protocol is particularly weird for CircuitPython since it needs variable clock-out (25, 26, 27 pulse) and the data's a 24-bit int that doesn't fit any Pythonic types 😢

[desert orbit]

thanks everyone! 😄

[brazen quail]

If using a IMU to control color, what is a typical throughput speed with low power micros like SAMD ?

[inner spade]

Dot star SPI has clock and data signal inputs and outputs. Speeds are much higher because the clock separately synchronizes the data rather than the neopixel method of extracting the clocking from the single data line.

Data speeds can also be set much slower for the dot star for the same reason.

[clever summit]

🇸🇪 👋

[eager matrix]

I use dotstar exclusively for all of those reasons. One of the best parts is you can also do a super slow SW SPI routine on an old slow processor. Synchronous protocols are much more flexible.

[modern night]

I think A7 should be TX for the bluefruit

cp.touch_TX I think is the command that should work

Oh I ran into that when I was doing the bluefruit examples rework for pycon

ending up with the wav file being labeled by [filename]_wavefilename.wav

Touch sensitivity is automatically adjusted each time code.py runs. Looks at the environment, pin capacitance, etc. That’s why it’s a good idea not to touch any pins during instantiation.

Yes, the Gizmo connections could foil the ability to sense touch.

Web Sockets get my vote

[inner spade]

The network stuff gets my vote, too. Of course I'm still interested in wrapping up this one: https://github.com/adafruit/circuitpython/issues/6236

Yes, line 119 in the code.

I tested it and 500Hz worked just fine.

We need to test for audio interference.

Super!

Yes, audio on the internal speaker.

Saturday morning stream starting now on Twitch: https://www.twitch.tv/foamyguy_twitch and YT: https://www.youtube.com/watch?v=SEGzZF_5C1A working on the core display brightness fix then network stuff.

[grand tusk]

hello all

[upper sandal]

oh I watched the replay and had a couple of things I wanted to mention before your stream

Concerning pasting in the REPL on NRF, the issue is here:
https://github.com/adafruit/circuitpython/issues/3152
I use a version of tio with @robust horizon's fix of sending characters in chunks rather than one at a time. (From https://github.com/tio/tio/issues/110)
NOTE THAT my version also changes the shortcut from ctrl-T to ctrl-A because it's easier to reach (for me at least) and the same as screen that I was used to.
https://github.com/Neradoc/tio/tree/nera-main

tio is not super updated

that's why I made the changes myself, I just build it locally and put it somewhere in my path

[clever summit]

🇸🇪 👋

[upper sandal]

oh it's easy to build, like just:

./autogen.sh 
./configure 
make

[clever summit]

Have been playing with getting live streams notifications in Home Assistant. Works like a charm, my Google Mini now notifies me of new streams.

[upper sandal]

yeah it's the same with the pyserial PRs dan and I posted last year... it feels so much better to dev in Circuitpython where somebody will actually look at issues and PR

nothing to setup I had to install autogen actually but that's apt-get for you (brew for me)

[clever summit]

I have created a status display out of a LED strip. Telles me with red color if plants needs to be watered, if batteries needs to be replaced etc.

Vaccum robot needs emptying as ell, it stops working otherwise. 🙂

[upper sandal]

there is an issue on the builtin usb-to-uart of ESP32C3 where it's missing bytes, but that's a different port, not tinyusb, etc.

oh no the C3 is the smaller one, basically an ESP8266 replacement, no native USB, only a usb-to-jtag/uart builtin, but also bluetooth, it's their first RISC-V chip too

@smoky island delete the 1.3.0 tag in the pico-sdk submodule

it's shenanigans they did on their repo, and deleting the tag fixed it for me

cd ports/raspberrypi/sdk
git tag -d 1.3.0

I must admit I don't understand the actual problem

they moved 1.3.0 on the original repo, causing the issue, the same kind of problem that you get if you git amend and try to push

I think the issue is that CP is pointing to a commit that no longer has the tag, while also pointing to that tag, which causes conflict ??? The solution is to point to 1.3.1, which is in PR now

[inner spade]

Dropping the Titano's display backlight PWM frequency from 50000Hz to 500 Hz to improve the brightness linearity, range, and viewable threshold. The backlight LED array controller chip is unique to the PyPortals and TFT FeatherWings.

I could only test it on the TFT FeatherWing. The wing has the same brightness controller chip, but no audio.

500Hz gave the display a full brightness range.

[upper sandal]

ugh yeah, I don't understand that either

[inner spade]

If you recall, the Titano had a brightness issue. One of the examples appeared to fail because at a brightness setting of 0.4 or less, the display went black.

The brightness range should improve from the 50kHz 0.4 to 1.0 range to a 500Hz 0.01 to 1.0 range.

The source of the problem is the FAN5333 display chip in hardware.

The second test is to turn on the speaker and listen. Hoping that the 500Hz PWM signal doesn't leak through to the audio output.

import board
import time
import digitalio

display = board.DISPLAY

speaker_enable = digitalio.DigitalInOut(board.SPEAKER_ENABLE)
speaker_enable.switch_to_output()
speaker_enable.value = True

while True:
    display.brightness = 0.5  # should create the most "noise"
    print(display.brightness)
    time.sleep(1)

    display.brightness = 1.0  # should create the least "noise"
    print(display.brightness)
    time.sleep(1)

    display.brightness = 0.01  # used to check visible brightness threshold
    print(display.brightness)
    time.sleep(1)

I was able to see something at 0.01 brightness

Suggest that you listen without any audio first.

Just enable the speaker at 50% brightness^

See the code block in this message stream^^

I couldn't measure any signal leakage for the original 50KHz brightness PWM signal. Frequency was too high to hear, as well.

The frequency would be approximately one octave above middle C on the piano.

Try a couple of different brightness settings. The volume should be lower at lower settings if there was bleedthrough.

Once I get a copy of the image, I'll test it with the o'scope on the various PyPortals and with the add-on speaker.

If you're having trouble hearing it, then it's probably okay.

What you're hearing is consistent with what would happen with a PWM signal.

Do you have an add-on speaker?

Don't need to cut the trace. That only removes the on-board speaker from the circuit. The add-on will still work, just at a slightly lower volume.

Still will be ear-piercing. 😉

Yeah, there's a bunch of white noise in there regardless of the brightness setting.

We're just looking for the 500Hz PWM bleedthrough for this test.

Yeah, I could hear the white noise. Sounds like a 500Hz signal in there, too.

That's actually a 1.5kHz signal, I think. Hmmm.

Would be worth a test to see if the noise frequency shifts with the PWM frequency.

Is the noise a higher frequency, too?

Brightness of 0.0 and 1.0 shouldn't create any bleedthrough.

Yeah, my ears tend to work better for relative frequencies. I don't have Perfect Pitch.

10kHz would be annoying for younger ears and dogs.

I think that's why 50kHz was picked originally.

The brightness controller chip is used on the Titano and the larger TFT FeatherWing.

I think we can say that the lower PWM frequency makes the display work better but certainly has some bleedthrough into the Titano audio.

Can you also test it for the regular PyPortal?

We'll need to be concerned about bleedthrough for any board with integral audio (all PyPortals, PyBadge, PyGamer, Clue).

But I suspect it'll be the same for all boards, probably lower impact on boards without the FAN5333 backlight controller chip.

I have all the boards in-hand. Would appreciate having the builds since I can't do that myself.

[upper sandal]

uuuugh building with the IDF is so sloooooow

[inner spade]

I can also do the spectrum analysis to confirm that the PWM signal is what is being heard.

The test on the TFT FeatherWing would be for brightness range. I tested it on the larger TFT wing then ran around holding it close to audio devices to check for bleedthrough. Got some interesting stares from the family.

[upper sandal]

I'll look at circup

[inner spade]

Yes, and the Pynt, please.

PyPortals, Clue, PyBadge, PyPortal. I think that's everything.

[upper sandal]

FunHouse ?

[inner spade]

Just tested by PyBadge. No noticeable bleedthrough using my ear. Will connect the spectrum analyzer later today.

[inner spade]

The Pynt is missing the ADT7410 temperature sensor.

Yes. The FunHouse has audio, too. Good catch.

[upper sandal]

the pynt is identical to the regular

no, it's an alias, it's not built, it's a pure copy of the pyportal binary

[inner spade]

I have one. Hang on.

[upper sandal]

give me a sec, I'll give you the file

[inner spade]

PyPortal Pynt:```
Adafruit CircuitPython 7.2.0-alpha.1 on 2021-12-29; Adafruit PyPortal with samd51j20

that's where the aliases are defined

it used to be in tools/build_board_info.py but since that depends on the matrix, and the matrix needed it, it's there

build_board_info creates the PR to circuitpython.org with the list of all board and stuff

[inner spade]

Titano: The PWM frequency is definitely in there, but it's not contributing significantly to the overall noise. The solid portion of the top waveform is the PWM signal. The "hair" is the normal digital noise of the board.

I'm hearing more 60Hz noise, actually.

Yes, an FFT analyzer on my Rigol DS1054 o'scope.

Will do. Greatly appreciate your efforts on this, @smoky island. I'll be nice to have that larger brightness range for the Titano. It's particularly helpful to have more control over brightness when trying to photograph the display.

[upper sandal]

for future developments in latest, you could change the PLATFORM line in circup to make it work until the CP8 situation is settled, that should work:

PLATFORMS = {"py": "py", "7mpy": "7.x-mpy", "8mpy": "7.x-mpy"}

Dan was saying that we would have a CP8 bundle

so then it would be:

PLATFORMS = {"py": "py", "7mpy": "7.x-mpy", "8mpy": "8.x-mpy"}

but you can make the first change locally

[smoky island]

https://github.com/adafruit/circuitpython/pull/6416

[upper sandal]

yeah pip install -e .

ping me if you are looking at my uwebsocket port

I still need to put it in the bundle too 😅

[inner spade]

Super! I'll work on testing all the boards. So far, it looks like the new PWM frequency does bleed through on the Titano, but it's only slightly noticeable when nothing is playing. I don't think it'll be a showstopper.

[upper sandal]

I use it with OBS Websockets to make myself a little dingus that lights up an LED when recording, and buttons to start record and save the buffer

I think the library PR can be merged at this point and released

then I can update the core PR to it

and having a warning light when muted is cool too

so many times people forget to unmute 😉

yeah the plugins should be able to do powerful stuff, but not sure how they would communicate with a board from inside OBS

[inner spade]

Again, appreciate your efforts @smoky island . Nice working with you on the brightness issue.
