This is the firmware for my Hackaday project Repurposing an old nixie thermometer. It is based on an earlier project Irreproducible clock. Instead of driving multiplexed 7-segment LED displays, the board drives a 3 line to 32 line output expander which drives the nixies.
First release April 2022
You will need the Standard Peripherals Library, explained here and the include file from Protothreads.
