In this tutorial we'll see, how to interface 128*64 GLCD with PIC16F877A Starter board. We will be using KS0108 controller based JHD12864E display. There are many displays out there based on KS0108 or compatible display controller. They all work the same way, but make sure to check the datasheet for the pin diagram before doing the connection.
