FPGA driver for PSP screen

December 12th, 2009, 23:01 Posted By: wraggster

Friends are constantly giving us their old electronics. We love it because our junk box is a never-ending pile of possibilities. We’re really starting to amass a collection of LCD screens that are not easily interfaced and this project gives us some hope for the future. [Philip] has been posting about using an FPGA as a driver for a replacement PSP LCD screen.

Many projects source cell phone LCD screens that have their own driver chip that can be addressed over SPI for use with a simple microcontroller. More complicated screens need a more involved control scheme and this is where the Field Programmable Gate Array takes over. [Philip] lays out the steps he’s using to implement his controller, from setting up the correct voltage levels, to planning for coordinate addressing, and even some of his follies with reverse current. We think this would be a great way to introduce yourself to FPGA projects.
