Dear Gurus,

I'm designing an application using a PIC16F877A that communicates with =
another component (a gps module) through two serial pins (Rx/Tx). What I =
would like to do is receive gps messages in the PIC, do some processing =
and output them to a MAX232 that will connect to a PC.

Having said that, I have two questions that are intriguing me:

1) In the PIC datasheet, I only see RC6 and RC7 as serial ports. In this =
application, I will need two ports, one to communicate with the GPS =
module and another to communicate with the PC through a COM port. How =
can that be done?

2) The GPS serial port operates at 1.8V levels. Can I still connect it =
pin-to-pin with the PIC or do I need a level shifter in between? What is =
the voltage used in serial communication by the PIC16F877A? I tried to =
look at the PIC datasheet but I got even more confused.

Help please

Cheers

Padu
