Software Serial Port
PostPosted: Wed Jan 26, 2005 5:36 pm     Reply with quote
Hello...

I need to interfase a GPS (4800bps Inverted) with a PIC16F877 running at 16MHz. On the HUART I have a serial connection to the PC for Debug. My program is very simple, it uses two #USE_RS232 declaration, at two different speeds, and with differente STREAMS name (one is PC and another one is GPS).
The problem is that I can send Data to PC, but cannot receive data from the GPS. I'm using PortB.2 for receiving data... Do I need to set the TRIS register? or #USE_RS232 does it for me? Does anyvody experienced problems when using a software serial port?
Thanks
Ezequiel
