[Help/Advice?] Pi and usb pico projector

[MHz]

I have recently gotten a pico projector, it has a usb input on it for connecting it too a PC so you can use it as a monitor, I am about to start on seeing if I can get it to work with my Raspberry Pi, if you can help steer my in the right direction (and save me a lot of time failing) then please read on.

The projector is a TEC PP-700 (http://www.ishopiwin.com/en/appliances- ... p-700.html) it has linux on-board it (although I have no idea about any specifics), a Micro SD Card slot and a 2.0 USB on it's back, when you plug it into a windows PC via USB it shows up as two external drives, one of these is for you put media on it's on-board memory and the other contains an installation package called "EZ display v3.01" which is the software/drivers needed to us it as a monitor for your PC.

I have plugged it into my Pi using an external power source and the two drives are mounted and their content displayed, the projector also go's into "PC Mode", so this first step seems promising as they seem to be OK talking to each other on a basic level. I then checked what would happen if I connected it to a linux desktop (I had Ubuntu running on another computer), as I plugged it in the projector when into "PC mode" for a few seconds and then a green screen with grey lines was projected, I later read that this is a good sign and has been referred to as "the green screen of success".

I then started reading up to see if what I was going to try and do had already been done, at first google was giving me lots of things to read about "DisplayLink", I read a lot of articles about it but I don't think that's what I’m looking for. The most promising links I’ve found are these two: http://ao2.it/en/blog/2012/01/18/usb-pr ... -libam7xxx and http://ao2.it/en/blog/2012/03/30/open-s ... projectors.

All I have done so far is read articles and preform the basic tests I have already described, I have a few days free and am going to spend them seeing if I can get this working. If you would like to help my with this then please reply, or even if you have any advice/tips to help me set off in the right direction then please let me know.

If you need any more info or maybe some photos/video please just ask.

Thanks!

Simon.

Sir, you are probably need to program a USB driver for your projector. I don't know if it's possible to do it with Python. I'm afraid that you will need to mess around with kernel's source code.

I've done it I did have to mess around with kernel's source code.

If anyone is trying to do this just message me and I'll show you how I did mine.

I don't have a projector - but I'm interested in how you got it working.

This forum is heavily indexed by google (and the others I presume!), so if you could put some info on here as to how you got it working it is very likely to help someone out in the future!

[aumolac]

Yes, that would be interesting to see.

Hi MHz, I'm also very interested by your project.
If you can update us, why not with a small tutorial that would be great !

Well done

Hi MHz, I've got a Philips projector, with usb input for PC connection (like a monitor).
Actually I use an adaptor HDMI to VGA but it'll take power from the HDMI.
I'll prefear to use the USB connection to send video data only.

I'm very interested by your project.
Please update other info !

Thanks a lot

Input for monitor? Do you mean output?

If it is a projector that connects to a monitor then where does the Pi fit in?

Hi, MHz
I have an Aiptek usb projector , and i'm very interested how you did it because i couldn't make it work. Could you give me a small tutorial?
