Hello. I spent a entire afternoon in trying to get en interrupt on a PIC18F4420 on portb,2 working. At portb,2 I have the IRQ pin of an nRF24L01 attached. So, this pin drives low when data is received and I would like that the program jumps to the void interrupt(void) routine. For test purpose the program stays for ever in the interrupt function. With my code the int2if flag gets high before a change of portb,2 occurs, but the idea is that the interrupt happens if the pin is pulled down. To configure the PIC I made an init function: . void init(){ osccon = 01110000b; // interna
