My approach is using a SPI to collect 24-RGBs-Strips-Data and a SYNC from a impeded SoC. Another approach I came up with is to reuse the Adafruit-Neopixel-Library. I attached my FPGA_NeoPixel.h file. Technically it inherits from Adafruit_NeoPixel and overwrites the void show() with SPI-Code so you are able to use the methods from Adafruit_Neopixel to set leds or calculate color spaces. I have tested it on an Arduiono-Nano but it is easy to port the Libs to other SoCs.
