External Touch Screen Input

[mattyv]

So i would like to install a 7" LCD monitor in my car that would take the VGA feed from the Atrix in the HD dock to be able to display things like the GPS functions, MP3 player, etc.

With the 7" LCD's on the market that have touch screen capability (through USB) i was wondering if this could be possible. The touchscreens usually require a driver to operate and i am not sure if there is a way to get the driver to work on the atrix where the USb port from the touchscreen would plug into the back of the HD dock.

Your thoughts would be appreciated.

VGA input on your screen won't wor - the atrix uses HDMI and you will need to convert between the two to get a signal out (VGA is analog, HDMI is digital).

Unless someone writes drivers for a USB touchscreen, as well as getting HDMI mirroring to work in the horizontal position (currently the hack only works for normal vertical orientation), then you're pretty much out of luck.

Using the Motorola Atrix as a CarPC brain is something I'm looking for! I have a Lilliput 669GL-70NP/C/T 7" with HDMI video-in, the touchscreen works over USB and it has a Linux driver. Shouldn't be possible to implemente it in Webtop?

As far as I understand, the driver would have to be precompiled for ARM, or the source code to the driver would have to be available, short of reverse-engineering it.

Yes, this concept is trivial, the questions are if it can be done, the amount of work necessary and if someone is willing to do it.

I personally have very few knowledge in Linux, limited to some terminal commands in switches and other devices, which is far distant to compiling something to another processor architecture!

I've been interested in doing this same thing in my car. You know there's an alternative on ebay but theyre expensive sitting at a litter over $700 and I only see them available on ebay. Its basically a double din dock that functions with or without the included docking device. The device is just a tablet that I believe stock is running froyo & it has capable specs, with 64 or 128 gigbabytes max memory, 1ghz, 512mb ram, I think its a nice size too, a little smaller than most tablets. I'll try and find a reference or link on ebay.

& has video inputs, etc.

I'm wanting to do the same thing using an HDMI connection, not sure if I can use the Atrix or have to build a car PC and connect the Atrix to it though

For all those interested

I have posted an offering for someone to see if they can bring this solution together using the Lilliput Linux drivers. If they can get it to work i have offered to pay. If it does indeed work, i will be happy to share with all of you and defray the cost to me, and or provide more $ to the develper that succeeds.

I will pitch in 3 or 5btc for this bounty.

Would it be possible to use the current webtop hacks to change the webtop to ubuntu and get a touchscreen to work with it? Just brainstorming. Dunno if it's even possible or not

it's a sound thought pattern, however that is not the issue.
the touchscreen usb drivers are designed to run on the i386 architecture, where our phone runs on the ARM architecture.

aka our greek phones dont understand english

I'd translate it myself if I had the source code to the i386 driver and some learning material XD

depending on the filesize of the i386 binary, it would be possible to reverse engineer, however extremely time consuming (probably looking at months)

I too would be very interested in this!

The other option I was thinking about was to buy a 7 inch tablet and mount it behind the bezel in the dash.

In the car I am planning to play with, I would keep the stock Bluetooth-enabled head unit, and just sink it back into the dash some more with either a tablet or a touch-screen monitor sitting in between the head unit and the bezel so it looks good.

The good thing about doing it this way is that the stock head unit has steering wheel controls which will remote-control a Bluetooth stereo device, and also means no need for an additional amplifier.

I.E if I pair my Atrix phone to the head unit by bluetooth, I can play music and use the skip prev/next buttons on the steering wheel to control the Atrix.

So ideally I would dock my Atrix in the car and bring it up on the touch-screen monitor, be able to control through the external touch screen too.

Otherwise I would have a tablet permanently mounted in-dash, connected with Bluetooth to the head unit. Once again could control using the steering wheel.
