Hello guys,

I m working on a project "Navigation RObot using GPS Control" . I am using Garmin Etrex H and Pic18f452.

My task is to interface GPS with PIC and get longitude and latitude from GPS. I have connected RX pin of GPS with TX pin of PIC .In between i m using MAX 232 ,and I have made a simple program to get data from GPS to PORT B , but I m not getting anything pls help guys .

I have checked everything but couldnt get the error :(

If i connect the gps directly to PC ,i can see the NMEA coding on hyper terminal but when i connect it to pic i couldnt find anything .

Waiting for the replies desperately
