; Flipdot display - one PlatformIO project, two firmware targets.
;
;   nano       Arduino Nano that drives the Brose flipdot panels directly (USB upload)
;   nano_ota   Same Nano firmware, flashed over WiFi through the ESP32
;   esp32     ESP32 "brain" (WiFi, NTP clock, Home Assistant) - OTA upload
;   esp32_usb  Same ESP32 firmware, flashed over USB into ota_0
;   recovery   ESP32 recovery app (WiFi setup + OTA), USB only, see README.md
;   test_nano  Unit tests for the Nano firmware, run on the PC (needs gcc on PATH)
;   test_esp32 Unit tests for the ESP32 logic, run on the PC
;
; Build all:        pio run
; Build one:        pio run -e nano
; Upload one:       pio run -e nano -t upload
; Serial monitor:   pio device monitor -e nano
; Run tests:        pio test -e test_nano -e test_esp32
