rpi-ws2811

This project has the goal completing all the coding needed use ws2811 neopixel lights using a raspberry pi, for my xmas tree. most neopixels effects are written in C++, however i was only able to use a rpi with my ws2811 using python. I am porting all the c++ examples to python.

Install Instuctions

Please start with my fast install instuctions ( located on install.md)

Hardware Considerations

  • RPI 3b
    • SD = 16gb, Ram = 1gb, CPU = 4× 1.2GHz
    • OS = Raspbian
    • neopixel = 50 WS2811 (powered from RPI +5v pinout)
  • RPI 0W
    • SD = 16gb, Ram = 512mb, CPU = 1× 1GHz
  • 6.5ft tree
  • 300 programmable led (WS2811)
  • 2 power supplies (each 5volt/10Amp)

Notes: the RPI0W controling 300pixels runs about twice as slow as the RPI3b. I really notice it on the FireEffecT, but barely notice the slowness on other effects.

Start python script on startup
