pic16f877 ANx pins
PostPosted: Fri Feb 04, 2011 6:59 am     Reply with quote
Hi all,
I'm using pic16f877A. Currently I'm using pins B1,B2,B3,B4,D4,D5,D6,D7. I need 4 more pins for digital output. Which pins to use for this purpose? Can I use AN4-7? If yes, how?


Thanks in advance

According to the header file...

#define AN0_AN1_AN3 4 // A0 A1 A3

would allow you to use AN4 as a digital pin as well as AN5,6,7.

You'll also have to deselect the parallel port configuration.

All this is detailed in the header file.
