GPS (Global Position System) communicate with PIC.

Anyone know how to program and build PIC to control GPS receiver?
Once interrupt at PIC received, it will request GPS receiver latest info and send by SMS or display.

First of all, you do not need to 'control' the GPS module. The GPS module will stream out the NMEA 0183 data via UART automatically after you power up it. The thing that you need to do is to process the NMEA 0183 and extract the information you need.

How do build a circuit using PIC? Is it only using PIC Tx and Rx pin to connect to GPS receiver?
And the instruction code, how to grab the info and send out using GPS modem.

I think you should refer to the previous discussion that we already talk about.

Basically, you need to know the GPS UART is 3.3V, 5V or RS232. If it is 5V TTL, direct connection is fine. If it is 3.3V or RS232, you will need do have some level shifter or sometime called voltage translator in between. I think you may search the forum, I can't remember where, but we did discuss before. Maybe the links given by robosang is the link I said.

As for software, again, I recall we did have discussion before too, in this forum. So good luck and do show us result. Hope to see a photo of your result.
