salve a tutti sono uno studente e il professore ci ha dato per casa da realizzare il lampeggio di un quattro led sulla porta c di un pic (il PC16887)compilandolo con sourceboost (così si può vedere se funziona). io ho scritto questo ma non riesco proprio a trovare l'errore e vi chiedo una mano. #include <system.h> void main() { ansel=0; anselh=0; int cont; cont=0; trisa=0xFF; trisc=0; portc=0; option_reg=0x85; while(1) { while(cont<50) { intcon.TMR0IF=0; TMR0=100; while(intcon.TMR0IF==0); cont=cont++; } cont=0; if(portc.0==0) { portc=0xFF; } else { portc=0; } } tmro==0 questo è quello che mi dice quando lo compilo: Building...
