||
* VFX Review — ESP32 dot-matrix dashboard
|
||
*
|
||
* Hardware : ESP32 dev board + 4× MAX7219 8×8 modules chained (8×32 display)
|
||
* Libraries (install via Arduino Library Manager):
|
||
* - MD_Parola by majicDesigns (≥3.7)
|
||
* - MD_MAX72XX by majicDesigns (≥3.5)
|
||
* - ArduinoJson by Benoit Blanchon (≥7)
|
||
*
|
||
* Behaviour:
|
||
* Normal → scrolls "APR:142 CHG:12 TODO:38" on a loop
|
||
* Event → interrupts with e.g. "OK SH0010" / "REVISE SH0010" / "NOTE SH0010"
|
||
* held for NOTIFY_HOLD_MS then resumes stats scroll
