How To Control What You See On A Screen in Two Hours and For Less Than $25!

Imagine how cool it would be to control what appears on your screen and at a bargain price, just using your FPGA (yes! Your Papilio!) and some other easy-to-get components.

All you need is read today´s article (and buy the tiny things of course). This how-to post is one of those which are written thinking of the user. It explains everything, even the physics that rule the system.

For this specific example, a DAC resistor is connected to the FPGA on a CPLD board so it can output 512 colors to a VGA screen. Knowledge of VHDL is needed in order to implement your own code, otherwise, simply use the one given although you can follow the links on the article to learn some more about VHDL.

The real advantage is that you will be able to implement your own VHDL modules so you will actually control what appears on the screen!

Now it´s your time. Show the World what you can do…through a VGA monitor!
