As a next step of FDIM controller evolution I'm trying to use ESP32 board as its heart. That should allow to read and write some cool text info as track names or navigation hints - and get this data via WiFi link or Bluetooth connection. Code compiles, but may need modification to Sodaq_DS3231 library - inclusion of pgmspace.h should be surrounded by ESP32 macro check (exactly as in can-clock.ino file)
