The SDA5708 is 8 digit 7x5 led matrix display, the font used by the display is defined in software.

This is a C library and example to control the display using a Raspberry Pi Pico communicating with the display using SPI.

You can copy the files sda5708.h sda5708.c sda5708_fonts.h for use in another Pico project (remember to add sda5708.c in the CMakeLists.txt). It requires SPI library in the project.
