RC6 & RC7 normal I/O problem
PostPosted: Tue Oct 30, 2007 2:23 pm     Reply with quote
I have been running into some trouble using rc6 and rc7 as normal I/O pins. I have set all the triss values as needed but i still am not able to use those pins as normal I/O pins. Is it possible as the data sheet says or do i need to do other adjustments as well?
It is for a 16F886 pic.

Make sure you don't specify those pins in a #use rs232() statement.
If you do, it will turn on the hardware UART, which uses those pins.

Could you please look at the code at the folowing website. I see that they have set the Xmit in the defines file but i cant see where it has been used so i am thinking of removing it. The pic is still the same 16f886 conected to a cc1000 but not through the rx and tx pins.

The code uses the serial port in a large number of places:
Code:
GetSerial();
PutSerial();
printf();
getc();
kbhit();
