This video shows a HUB75 LED matrix panel with 64x64 full RGB pixels driven by a RP2040 Raspberry Pi micro chip. It runs at 50Hz frame rate in BCM mode to get an absolute flicker free display. This is only a tiny demo program running several tasks using FreeRTOS.
The driver uses 2 state machines of one PIO device. Each state machine is feeded by a DMA channel providing RGB pixel data and row address data.
