HI ALL,
Using portb as output : working well.
Using porta.0 to 7 except porta.4 & 5 as input with pull-up resistor working well with 0v trigger, Can i use also a pull-up resistor to porta.4 &5? or do i need to use pull-down resistor then trigger with +5v input.. Looking for help before messing up my IC.( didn't try yet,)
Thanks.
