PORTC on pic16f76
PostPosted: Tue Mar 30, 2004 12:41 am     Reply with quote
Hello
I'm using PIC16F76 .
I made a simple program which turns on RC5,RC6,RC7 in a cyclic way (5,6,7 and then again 5,6,7,5,6,7...)
now, I can see the wave on the RC6,RC7 but not on the RC5.
The tris value is set to 0x18 (5,6,7 are output)
am I missing something which is related to the peripherals?

Are you using set_tris_c() to set the directions, or are you writing to TRISC directly? Debug through your code. Does TRISC stay 0x18? What other peripherals do you have on PORTC? remember if you have any preperals on PORTC the compiler handles the TRISC in a different way:

Post your code.
