I have currently been using some terminal emulation software on my PC to see the output of the Z80 computer. It seems a little silly to rely on a large multi-gigahertz, multi-megabyte machine just to display the output from a machine at the megahertz and kilobyte end of the scale. I had previously done some work with a dsPIC33 to drive a 320×240 pixel graphical LCD so dug out its breadboard and dusted off the code to try to make something of it. Inspired by John Burton's recent experiments with PAL TV output I decided that the first thing I should do is add support for TV output.

In a previous entry I mentioned that I had purchased a PG320240H-P9 graphical LCD. This is a 320×240 white-on-blue pixel display, and it does not have an on-board controller or RAM. To display something on it you need to constantly refresh it with picture data; in this instance, sending four pixels at a time, starting from the top left and working from left to right, top to bottom — a bit like the scanning pattern of a CRT monitor. Connecting a circuit to the LCD is made slightly more tricky by its use of a 16-pin 1mm flexible flat cable.
