I replaced the guts of my old alarm clock, so one less clock to set for Daylight saving time.
I used recycled 7 segments displays from old cable converter and pair them with 2 smaller ones. The vintage displays use a lot more current than the green ones. 50mA vs 20mA.
Both versions on github: https://github.com/FPGA-Computer/LED-Clock
STM8 USB library - Last lower level library removed and save some more space.
Timer is updated to V2: https://github.com/FPGA-Computer/Timer
I added a connector for a nRF24 module as part of the V2 overhaul. I might not need it now, but it is much less work later when I do want one.
