Remote over GPIO TFT Touch Display?

[dju010]

Hey everyone

Quite new around here, but I looked for an answer everywhere, but couldn't find anything. Sorry if I missed it though.
Here is my idea:
I currently have setup the RPi with XBian and hooked up to my projector. Everything runs perfectly.
However as remote I use the iPhone app. Whenever I need it, my battery is low or I have to change the display settings in order to use the app properly.

Now my question:
Would it be possible to hook up a TouchTFT Shield over GPIO to the RPi and display a remote there while the main XBMC display goes over HDMI? I read here here that it is possible to have both outputs used.

So I would have a "dual screen setup" with Screen 1 -> HDMI as now and Screen 2 -> GPIO with just the remote (maybe even what is played info) on it.

Possible? If yes, how to?

Thanks for your help and responses!!

Which means support for these type of TFT touch screens:

hey, this is great, especially for this cheap price. do you know a video online that shows such a display in action?

-> As I see, you requested this, but it isn't yet part of XBian, right?

Yes, exactly. I thought about this product as an example.

Anyone any ideas how to build it yet?

@Freem@n, a video in the OP link.

@CurlyMo thanks, got it. I could have thought about that myself but it's getting late already. ;-) the small tft looks promising to me. if it would be able to mirror your XBMC from your main monitor onto that screen you could use it when playing music and turn the big screen (HDMI) off, right?

[CurlyMo]

Not sure if you can switch framebuffers on the fly, but indeed you should be able to run the XBMC gui on any framebuffer.

Another possibility would be to make a remote with one of those screens, an Arduino pro mini and battery.

I ordered one last week and intend to use it with arduino projects, but I think it's possible to use that to talk to the pi via various means (i2c, spi, network, wifi, RF etc).

I have many projects to do before anything like this, but it's worth a thought as a small arduino board is very cheap.

Another, but not so glamorous option would be to use the PIFace. One of the proposed projects was to get it working with XBMC but I’m unaware of anything definite at the moment.

Though someone has got something working, so it is possible. http://www.youtube.com/watch?v=IA-ULjvy91M

Interesting, so it is already possible to have the "status" displayed over GPIO. So all I need is some buttons or the touch interface in addition to it.

Any idea if the PIFace is part of the XBian kernel?

Idea:
Install CLI browser (as seen here) and display it on the GPIO display and access it over localhost:8080

Would that be possible? Inputs?

[CurlyMo]

My plan is to write a custom FB GUI for these displays.

The PIface has 5 buttons and a toggle switch, so it should be possible. Also there is a XBMC addon, which should work with it LCDProc but as of today I have not been able to get it to work with Xbian - dependancies etc, but it's early days.

Of course, but touchscreen + full graphics is much cooler. Since i know how to program for the framebuffer, creating a (basic) gui should not be that difficult.

Hi!

I want just run the XBMC GUI at my TFT Display via GPIO
It is a 2.8" (320x240) with Touch, so it should be possibe to control XBMC like a full pocket media player.
I just like to play music via NAS Share or Internet radio - no video!

My display comes with a framebuffer driver - but until now i was not able to get the XBMC screen on the little display

Any idea?

@Eikatis

there is kernel with compiled TFT drivers as CurlyMo requested here:
(untested)
