I'm working on my secret project, cannot tell details but need advice/help.
Ok, here's my problem: I disassembled a PSP 1000, taking out the screen and the big/main circuit board w/ its speaker connectors attached (part where the screen
connects to) and today I bought a AV gameduino (one of these - see link)
and I already have the arduino Uno and the small breadboard and the shield maker set, and I have the SD memory card holder, quad AA battery pack, now I'd like to somehow (that is, after I
re-connect the PSP's original screen to its original circuit board) connect the new gameduino I just bought today to the PSP circuit board/speaker/screen assembly and somehow rig it up for video/audio output (that is, make the video from a movie that is stored in MP4 format on SD card to output from the PSP's original screen - how do I rig this all up to be as compact as possible and make it work the way I want?
I also have the Arduino programing sketches book too.
Help, please?
This is supposed to be a standalone project (run independantly of computer/internet connection) after its all set up
how do I rig this all up to be as compact as possible and make it work the way I want?
Post all the links to the stuff you want to connect .

I don't know how you are going to convert an MP4 movie to output to a PSP's screen. First you have to specify what kind of video signal the PSP's screen takes. If it is NTSC , then I guess you need to find something with an NTSC video output that accepts MP4 format ,which is not a video signal format , it is a file type so you need something that READs MP4 files and outputs NTSC video.
About the only thing I can tell you is you may run into a wall trying to read and play MP4 video files with an arduino..
Well, it doesn't really have to be mp4 video, it can be avi video, etc, i have any video converter (piece of software that I d/l a year ago) on my computer that allows you to convert avi video, or mp4 video to just about any video output format, even psp 1000.
This is what I forgot to mention that I also have.
I think what Dave was telling you is that besides the voltage level shifting issue, the screen requires a 9Mhz clock and it's 24 bit PARALLEL DATA (only twice what you have available). In short , your plan to use a scrap psp screen is a pipe dream and it's not going to happen and the sooner you accept that , the better. (for you , anyway). If you want a good graphic screen theres plenty available. Btw, even if you could overcome the hardware issues, the chance of you being able to program it are probably just as slim as the chance you'll get the hardware problems solved. I've never used a psp and couldn't tell you anything about it, but what Dave said doesn't require any knowledge of a psp to understand. You don't have a clock signal. You don't have enough data lines. The voltage levels are different. There is probably another issue Dave didn't mention and that is the timing would be all wrong running on an arduino because it's too slow.
Ok, would that sceen from spark fun do what i want it to do instead of that psp screen I removed?
And that gameduino just arrived today, would this work with that spark fun screen you linked me to?
I mean, substitute that spark fun screen for the video output instead of that pulled psp screen - I think I'm beginning to understand the difference, and why that psp screen would not work, b/c the pinouts are different (just my guess)?
I don't think you are getting it. Both the PSP and the Sparkfun screen are 24-bit parallel. Look at the datasheet. Do you have 24 parallel I/O lines available ? Do you know how to generate the horizonatal and vertical sync signals ? What do you have that is fast enough for the clock signal ?
Programming?
Arduino hardware?
Arduino software?
PSP video or any video processing (and I don't mean, you have a program I downloaded, to do it!)
Electronics?
Have you programmed anything into an Arduino yet?
If yes what have they been?
As has been explained, the project you are trying to accomplish is probably beyond the scope of an Adruino.
I'd say what you are trying to accomplish can already be done with a PC/laptop , neat, tidy, nice screen, portable, multi format.
Or Ipad, galaxy pad.
Re-inventing the wheel.
and it fits my needs perfectly. tonight i successfully converted one of my movies into mp4 and put it on this player, it was a snap. the movie plays perfectly on this device.
now i'm thinking of somehow getting arduino, programming it to talk to this device (disable all apps, only power on, play video, power off) but how do i do this?
No, because your wasting your time. It's not going to happen. I don't know where you got the idea it was possible in the first place but it's not going to happen.
