Autoradio – Medion MD4366 – Display frontje aansturen
Deze pagina beschrijft hoe je het display van een frontje van een Medion MD4366 kan aansturen met een Arduino.
De autoradio
Info
LCD Display chip
Als je het frontje open schroeft, zie je een chip zitten, deze stuurt de LCD aan: LC75823, het protocol is SPI (MISO/MOSI)
