FPGA driver for PSP screen

[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.

the psp screen is a standard issue parallel tft screen with widely available data sheets

people are using them all the time for pic and avr projects for years now, why deal with designing your own propitiatory cpu on fpga as a starter project, when you can bit bang it with an 8 bit arduino using standard lcd practices


oh and guess what, there is a widely available xy serial touch screen add on, 4 wires

Do you suppose one would be usefull in making one of those portable Nes things, something ala ben heck?

Just asking...

[osgeld]

probably, those are done on fpga, all hardware emualtion + io support to whatever you have hooked up

but its far from a starter project, your looking at a couple hundred in equipment just to have a dead board looking at you

its a good start for making some projects..
look. i have like 7 screens so i may want this little device and make my own.... photoframe? extra screen on the car? many possiblities on my mind... yet, its not on sale i guess
