I'm using the Microchip PICDEM board to test USART on the 4550 PIC.
I'm using the default settings and the test code to tx/rx data via
USART. I can Tx data but Rx doesn't work at all. I've tried all
routes to get it working - any ideas? Is there any pins I need to set
up although I've already tested with: RISCbits.TRISC7=1; and
TRISCbits.TRISC6=0; but still not working on Rx. All Baud rate
settings, SPBRG/H etc are set up and seem fine... What am i missing to
get Rx working?????
