DPI-Pi

18Bit DPI & Back Light Driver for Raspi

This is a Small PCB Design aiming at using a parallel RGB 3.5" screen directly from the ras-pi GPIO Pins

The Screen used is: Model No. LQ035NC111 320x240 3.5" and is popular in GameBoy Projects.

Ammendments will need to be made to /boot/config.txt on the pi.

dpi-pi's Issues

Artifacts when viewing higher color depth content

I'm noticing some odd imperfections in the image on screen that look like color drop outs or artifacts. I'm only noticing this in EmulationStation, RetroArch menus, and some PS1 games (usually during FMVs). All other content looks great and I don't see these artifacts.

Things I've tried
First, I double checked to make sure the config file matched your supplied file and it does. Next, I double checked for continuity between the 54 pin connector and the GPIO, PWR, or GND they were connected to with no issues. Then I inspected the 54 pin connector under a scope to make sure there were no solder bridges I may have missed the first. No bridges or other solder related issues. Finally, to rule out any sort of hardware issue, I built a second DPI board and it exhibits the same exact issue.

Inductor

Hey there. Looking to build one of these. The inductor part number doesn't seem to match with anything on arrow or digikey. Do you have a link to the one you used? Or more information on it so I can select the right one?
