Control WS2812B LED Matrix using your Raspberry Pi 5
The Raspberry Pi 5 added a separate chip for handling its peripherals (RP1) which none of the previous Pi models had. Pre-existing Open Source packages that controlled WS2812b LEDs are now obsolete. This is a C Driver for the new Raspberry Pi 5 RP1 Peripheral chip that can be used to control your WS2812b LEDs.
Run from your Linux based Raspberry Pi 5 terminal
Huge kudos to Praktronics for figuring out the SPI RP1 register addresses
To Run Example which turns on 1st LED Green:
Ensure hardware connections are made as shown in Connections photo below:
git clone https://github.com/jovank2001/pi5ws2812b.git
cd pi5ws2812b
gcc rp1Spi.c rp1SpiUtil.c pi5ws2812b.c -o run
sudo ./run
Example Result:
