Help with Controlling WS2812B on Banana Pi CM4 (Issues with WiringPi, RPi.GPIO, and Adafruit Libraries)

Hello everyone,

I’m currently working on a project with a Banana Pi CM4 and am trying to control WS2812B LEDs, but I’ve run into some issues and could use some help or suggestions.

What I’ve Tried:

  1. WiringPi: I followed the instructions on the official Banana Pi page for WiringPi:
  • I successfully built and installed WiringPi.
  • I can use the GPIO pins for basic tasks like output and PWM with GPIO 26, but I’m struggling to control the WS2812B LEDs.
  • According to the documentation, WiringPi only supports setting the GPIO pins to output, input, or PWM, but I couldn’t find clear instructions on using it for controlling the WS2812B specifically.
  1. RPi.GPIO: I also tried using the RPi.GPIO library, which I installed by following the guide.
  • After installation, I tried to use it for controlling the WS2812B LEDs but encountered the same issue: compatibility problems with the board, and I couldn’t get it to work.
  1. WiringPi-Python: I installed WiringPi-Python following the provided steps, but I still couldn’t get WS2812B support, and the LEDs did not respond as expected.
  2. rpi-ws281x: I attempted to use the rpi-ws281x library, which is commonly used for WS2812B control, but I received an error stating that the board is not compatible with this library.
  3. Adafruit NeoPixel Library: Lastly, I tried using the Adafruit NeoPixel library, but it gave a similar message indicating that the Banana Pi CM4 isn’t supported.

What I’m Looking For:

  • Has anyone successfully controlled WS2812B LEDs with the Banana Pi CM4?
  • Are there any specific configurations or workarounds I need to apply to make these libraries work, or should I try a completely different approach?
  • If anyone has used an alternative library or method, could you share how you set it up?

Any guidance or suggestions would be greatly appreciated! Thanks in advance!
