Hello Everyone,

Iam doing a project on gps using pic 16f877a.
GPS Receiver with Active Antenna [1216] : Sunrom Technologies, Your Source for Development

My gps module will continuously transmitting datas. I want to filter latitude,longitude and speed from that.

I have written program for that. But the problem is that iam geting correct output during simulation. But it didnt works with hardware. It will execute only once and after that it didnt repeat. Iam attatching my code below.
My compiler is hitech C.
