Salve a tutti!
Mi sono da poco appassionato ai sim racing.
Dopo aver fatto la parte meccanica (un freno a mano collegato ad un potenziometro lineare e una botton box con encoder, switch e semplici pulsanti) ho provato ad unire due programmi gia fatti trovati in rete in modo da aver un solo cavo usb collegato al computer al posto di due.
Ho modificato il programma in modo che il anale A0 funzioni per il potenziometro lineare mentre gli altri canali servirebbero a gestire 4 encoder e 15 pulsanti.
il problema nasce che facendo una prova in impostazioni dispositivo il programma sembra funzionare ma nel momento che il potenziometro va a 0 mi si accendono 4 pulsanti e non appena sposto il potenziometro di qualche mm verso il lato opposto questi pulsanti si spengono.
Il tutto l'ho provato collegando fisicamente il solo potenziometro.
C'è qualcosa di sbagliato nel programma?
