using p18f45k50
Issue.. if (INTCONbits.IOCIE == 1 && INTCONbits.IOCIF == 1)
if (PORTBbits.RB4)
These just don't work and I don't understand why, pulling my hair out :-(
And if I just use if (PORTBbits.RB4) it has to be if (!PORTBbits.RB4) and then it works on button push, don't understand
the ! not ? when pushed
