[RESOLVED] How to change the use of Tx I/O during execution?
PostPosted: Fri Jan 19, 2007 8:07 am     Reply with quote
Hello,

I am writing a test program for my product and during the test phase, I would like to change the Tx output (Serial communication) into a standard I/O port. Same question for Rx input.
The serial communication has been setup by using the #USE pragma.


thank you for your help.
Franck

I have found ! here under the solution:
Code:

bit_clear(RCSTA1,7); // Serial port 1 disabled
bit_clear(RCSTA2,7); // Serial port 2 disabled

I like setup_uart() better than the direct register addressing.

Code:
setup_uart(FALSE, stream)   // disable uart
setup_uart(TRUE, stream)   // enable uart
Stream is an optional stream identifier.

I noticed this command also toggles the RCSTA.CREN (Continuous receive enable) bit which might be an improvement over your code.
