i use pic16f877a
i want the itilization to turn off the analog i/p
in port A pin 5 not work as o/p digital
but i sure that dosent burned

 

If you define the pin to work as an analog input then it cant work as a digital output too. Just dont define it to work as an analog input.

This may help you, it contains all the instructions for PIC in C:

You need to set register ADCON1 to 0b_0000_011x for all the port A pins to be digital. then TRISA = 0 will set them to be outputs.
Have a look at the datasheet for other settings. You don't have the option of setting A3 to digital and the rest of PORTA to analogue.
I have tested the above with a 16f877; I do not have the "A" version.

I use JAL for most of my programming.
