GP display controller


Posted on Sep 27, 2012

This is a simple display controller. It can be controlled with a small microcontroller, such as MCS51, 68HC11, Z80, AVR and others. Several years ago, I found an article that controlling a TV with only a PIC micorcontroller, and I surprised to it. It is very interesting to attempt to synthesize video signal with a micorcontroller. However, it is not suitable for practical use because the microcontroller is occupied in synthesizing video signal, it cannot process any other operation. Therefore, this technic can be applied to a toy at the best. It is required a display controller to contorl the video monitor, so I designed and built a simple display controller for RGB monitor and TV monitor.

This is the circuit diagram for display controller. It is very simple, isn`t it? It is using only three ICs, number of wires is reduced compared from previous project. Each part in this project is not special, so that whole parts will be found in Aki
