Driving a PSP screen with an FPGA

Here’s [FlorianH’s] setup for driving a PlayStation Portable screen with an FPGA. He’s using the DE0-Nano board to do this, and the first order of business was to establish a way to connect the two. He did a great job of etching his own breakout board, which has some traces that are less than 10 mils thick. Soldering the connectors for the screen was a bit of a challenge, and he shared several pictures of the process for your enjoyment.

With everything hooked up he fired it up with just a couple of lines of code to draw a test pattern. From there it was on to building a more intensive driver. [FlorianH] mentioned to us that he’s just starting to learn about FPGAs after having worked extensively with 8-bit microcontrollers. He’s been documenting his work on his site, and finds himself frequently referencing his own material so remember how he did things. Our vicarious enjoyment is an unintended (but welcomed) consequence of that habit.

  1. I was going to do a project like this, but then I realized I can drive it from a pic. Good job for getting it up and running.

    1. You can.

      Get Eagle CAD.

      Design board.

      Send board gerber files to spark fun.

      Get board back like that.

      It’s really easy.

    1. Hmm I was aware microchips were making the claim they’ve got a graphics driver suitable. I find myself very, very skeptical of everything they do, however, and I was sort of hoping to see someone having done an implementation.
