In this tutorial we will look at interfacing KS0108 display controller based JHD12864E display. There are many displays out there based on KS0108 or compatible display controller.

We have it tested and working on 8051 PIC and ARM. We may do a similar tutorial on these MCUs as well. Unlike a 16 x 2 display, this does not have a character map for ascii values stored on its ROM.
