Hi,
I'm trying to get the RX and Tx to work on a 16F648A PIC with an LCD. The LCD data pins are connected to PORTB high byte. The RX is working ok, but the when the TX outputs it's signal, the voltage is 0 to app 1V swing. I've tried switching TX on and off but this has the same result. So can the Tx be used when an LCD is connected this way?
