capire il tft uno r3 2.8 touch screen

-

salve tutti,
ho acquistato il display in oggetto che utilizza l' ili9341, e dai test che ho fatto con le librerie modificate trovate su internet, funziona tutto. non riesco capire però perchè utilizza così tanti pin... con lo spi non dovrebbe utilizzare 4-5 pin solamente? vi chiedo questo perchè mi farebbe comodo poterci inserire sotto anche uno shield w5100, ma dovrei capire quali pin realmente utilizza...
allego anche il retro del tft dov'è riportata la serigrafia dei pin



grazie 1000

su quella scheda ci sono 3 dispositivi: il display, lo touchscreen e la lo slot per la scheda di memoria sd.

secondo me il lcd viene pilotato in paralello 8 bit con 13 pin e la sd con la spi. il touch non come é collegato.

puoi collegare un ethernet ma devi modificarla per poter usare un pin libero (per esempio a5) come ss.
comunque dato la limitata memoria ram della uno ti consiglio di usare un genuino mega 2560.

ciao uwe
