Waveshare Electronics Pico-Clock-Green (a.k.a. ws-19695) contains a large LED matrix display which is driven by two SM16106 shift registers and one SM5166P address decoder.
This project creates a controller for Pico-Clock-Green display using Raspberry Pi Pico (RP2040) PIO and DMA functions, thus taking no CPU cycles for controlling and refreshing of LED matrix display.
There is also a custom display driver included for using ws-19695 pio controller together with olikraus' excellent u8g2 monochrome display library. This opens up all possibilities of using ws-19695 as a standard LED matrix display without the need of writing any graphic output code.
