Dual RS 232 in PIC

[dreamproject]

Hi all,

Is it possible to interface two serial (RS 232) devices to one PIC . Need to connect a serial GPS receiver to a serial mobile phone cable. I've known till now that there is only one UART port on the 16f877 but I just heard that a software implementation of the serial port is possible.


Thanks

Yes it's easy to do two, for that matter, as it's likely you only need one way communication?, you could use the USART for both.

Check my tutorials for software RS232.
