Drive WS2812B LED strips from a PMOD device, a lightdriver project @ anfractuosity.com:
I created a PMOD module PCB using KiCAD, that enables connecting WS2812B lighting strips to an FPGA board with a PMOD interface. The board was assembled by JLCPCB.
This is my first project using an FPGA, I plan to soon implement an SPI interface with the FPGA, to accept colour pixels via SPI from a raspberry pi, to then drive the LEDs appropriately. I am making use of the original Zybo board which uses a Zynq FPGA, although I’m not using the ARM portion of this chip as I want to learn VHDL.
