#which board, which version of
half kayak
yeah one sec
sorry, using the most recent 8.x on rpi pico w
8.2.9
I've actually sliced off the controller on https://www.amazon.com/gp/product/B0C1ZFNNKV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I know they are 5v based on opening the control box and seeing the silkscreens on the pads
I know folks have done this previously as well https://www.reddit.com/r/WLED/comments/18l6c80/this_is_govee_curtain_lights_connection20_led/

it seems these are more complicated: https://www.reddit.com/r/WLED/comments/18l6c80/comment/kdzu4ad/?utm_source=share&utm_medium=web2x&context=3
do you have this working with regular WS2812 strips (NeoPixels?) Do you have any of our strips?
half kayak
I can find a strand of generic ones real quick
@uneven latch it does not seem to work on a small strand of ws2812b
>>> import neopixel, board
>>> pixels = neopixel.NeoPixel(board.GP15, 20, brightness=0.3)
>>> pixels.fill((255, 255, 255))
>>> pixels.show()
nothing illuminated, and I've confirmed the voltage is correct between the pads on the led strip
and for gp15 I have it on the bottom left pin of the rpi pico w https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/pinouts, ground is shared between the power supply and rpi pico w and led strip, pico powered by usb and leds powered by pwoer supply

GP15 is special. Try a different pin.
half kayak
I tried 14 before that
how is 15 special? It looks normal on the pinout
just tried with 13 as well, no light
fwiw I also just pulled this board out of the packaging and flashed it
actually wait I have this strip backwards let me flip it lol
that works
hmm that's a shame, these were pretty stock lights otherwise
uneven latch
The reddit thread says that the Govee strips may have special controllers at the top of each curtain strand
half kayak
yeah there's a screenshot in the reddit thread but I thought they just handled passing the LED index
I assumed that'd be transparent
I can get my own of those strands form aliexpress thankfully though
uneven latch
I'm not sure that is true. We have no experience with these
you could try one of the sub-strands, but that involves more cutting
half kayak
yeah I'm sure that would work, but at that rate I might as well get my own and just run parallel strands
uneven latch
note that you don't need to call pixels.show() unless you set auto_write=False when you create the NeoPixel object.
half kayak
is there a limit to the neopixel package on how many leds it can control on a single strand? Or how many instances it can have?
it didn't write when I flipped it until I called pixels.show() again though
uneven latch
is there a limit to the neopixel package on how many leds it can control on a si...
it's limited only by memory size
there are no limits to the number of instances.
half kayak
great
uneven latch
how are you powering the strips? 5V from a separate supply?
half kayak
yep
uneven latch
and you have tied the grounds together from the board and the separate supply?
uneven latch
I have no extra advice about the Govee strips. How many strands do you want?
half kayak
I was going to make a matrix of ~38x26 that could be drawn on with a custom web app
I'll probably get closer spaced ones like this too
the govee seem to be 5cm spacing, 1.5cm spacing will look a lot better for writing stuff
uneven latch
we do have a library that lets you treat a daisy-chained bunch of strands as a matrix: https://learn.adafruit.com/easy-neopixel-graphics-with-the-circuitpython-pixel-framebuf-library
half kayak
oh that's nice!
uneven latch
we have NeoPixel matrices: https://www.adafruit.com/search?q=neopixel+matrix
half kayak
I need to make one that's like 1m x 1.2m
uneven latch
ok, that's a lot bigger than our NeoPixel matrices or our non-NeoPixel RGB LED matrices
half kayak
yep lol, it's going behind streamers on twitch
uneven latch
got it, good luck, sorry about the Govee. There may be software for it, but I have no idea. The supplied software is not helpful, hunh?
