Welcome back to the track of using your FPGA to display things. Today´s tutorial will teach you how to use the LCD screen of a PSP to display colour graphics from an FPGA. The main goal is to show three colour stripes on the screen but the author goes beyond that and adds a quick intro about displaying more complicated graphics. That´s for you to explore and invent or wait for the next tutorial.
The great advantage of using an LCD screen, instead of traditional screen is getting rid of the annoying analog VGA signals. Everything here looks like zeros and ones. On the bright side, LCD technology is pretty similar to CRT and thus the controllers take almost the same input signals.
As any other project from this guy, this one is also very thoroughly explained. You will find the part list plus all the schematics, among other nice stuff.
Although the core of this project is programming the FPGA with VHDL to properly control the PSP LCD screen, there is also some handwork. Quick thing but funny as always. Going back to the brain, it´s very important that you follow the theory explained to properly understand what the code is doing. Yes, the code is given, but you should understand what is going on there if you want to display pretty cool things.
What´s left now is you to take action and show us what you can display on the LCD screen!
Have fun!
