CircuitPython drivers for neopixels.
The adafruit_pixelbuf module is not found when running on a 2022 Raspberry Pi 4, with Raspbian OS. Steps to Reproduce: 1. Install with `sudo pip3 install rpi_ws281x adafruit-circuitpython-neopixel` 2. Create...
I use simple led move but it's very very slow in 1800leds ( just 30m 60led/meter ) ```py def run(position ,color , speed , size ): turnoff() for i in...
Hello there! ^^ I use my neopixel matrix 64 rgbw as a light source for my plant growing project. I have a light script, that implements sunrise, noon and sunset....
Hi, Is there a way to invert the signal so a single mosfet attached to a 5v pullup on the external power source can be driven.
Yesterday, did an upgrade on some Raspberry Pi 3B+ that use this library to drive a newpixel ring as part of an interface application. After the upgrade, the rings stopped...
I did try methods like this: https://raspberrypi.stackexchange.com/questions/85109/run-rpi-ws281x-without-sudo with no luck. Please post one root-less way of using neopixel on RPi.
The neopixel_cleanup from the underlying neopixel_write module method should be called on deinit(). Without this call it is not possible to change the pixel lengths in the same process. The...
Playing around with NeoPixel I thought of building some stuff on top using the slice syntax i.e `pixels[:len(pixels)//2] = (255, 0 ,0)` Which currently fails as the colors tuple must...
FlakShim in discord #help-with-circuitpython on Sept 25 reports that `pixels[i] = (10,10,10)` is 4x slower than `pixels[i] = [10,10,10]`. Confirm and investigate. No obvious issue noted in NeoPixel code; might...
Hello, i am having an "Issue" with the speed of the show() function. On a Pi Pico i get an execution time of the show() function of around 46 ms...
