GPS LCD Display Project - This is a project that I started back late 2003 when I just starting to learn PIC programming. I wanted to building something that actually did somthing useful. This project is based on a PIC16F84. I actually came up with this idea and then after doing some searching I found that a few people had the same idea. But, I wanted to build my own that I could call mine, developed by me. The whole idea is, I have several GPS units with no display __ Designed by Jason KE4NYV from Roanoke, Virginia
