I have revised my Python drivers for the Holtek HT16K33 display controller, combining Micropython and Circuitpython versions into one and adding support for Adafruit’s Bi-colour 8×8 Matrix in the process.Continue reading

Unlike all ‘serious’ micros, it’s perfect for connecting to and controlling a whole stack of add-ons, including sensors, displays inputs and actuators.
