Controlling a 20×4 LCD with PIC16F690

I created this project to write and test some LCD control routines. I wrote this in C.

I’m using this LCD in 4-bit mode, to save I/O lines. The breadboard holds the PIC16F690, the Brain. There’s a small header segment for ICSP (In-Circuit Serial Programming), as it should be. I’ll talk about ICSP later.

The LCD displays 2 centered messages “Systems Online” (first line) and “Kike Roxz” (second line) in an alternating fashion.

I will be using these routines for my next project… what will it be…?! ;)

P.S. I really have to get a new camera this one sucks! :(
