Great Project. The currently available (in 2024) 4 digit display (from AliXpress) requires the TM1637.h library and will not light up with the STM32_TM1637 required library. The code needs changing to use the TM1637.h library which unfortunately looks more involved than I am capable of. Hopefully the author can update the code to use the newer library?
