Touch screens are notoriously expensive, why not just buy a $10 Chinese touch screen overlay? they sell them on ebay & you just plug them in via USB,

After all like a previous poster said "its only resistive film overlay" that you can put on any old monitor.

I'm trying to follow what you did but I've got stuck at the "make then make install" part. I think you need to point it at the make file? Is it the am or the in file? Am I missing something?

Ok so I had been trying to do this on a raspbmc img. I got all the things I needed installed (I think) including gcc and other things. But I still don't know how to actually run xinput-calibrator from the terminal. I went back to a weezy Raspbian img and these instructions worked great. So can I take some config files from raspbian and use apt-get for installing xinput and get the touch screen working for raspbmc?

I have a few 3com Audreys collecting dust in the garage and was thinking of updating one of them with the rasberry pi. The problem is if the LCD could be interfaced to it. It has a PANASONIC EDMGRB8KJF 640 x 480 color stn display with resistive touchscreen. there is a powering board for the ccft light that could be reused. Interfacing without some supporting hardware might be a problem. Data (pdf) for lcd can be found @ www.openhardware.net/Documents_Lib. Might anyone have any ideas? Thanks -SF

Hi thutchis,

please let us know, if your touchscreen monitor works fine on raspbian??

Thanks

Diego

I think in all of these products, finding a touchscreen driver will be the challenge. I am hoping the Touchkit Driver for Debian will work http://www.touchkit.com/drivers.htm for these cheap LCD screens. We'll see when my AliExpress touchscreen arrives.

At $140 it's a pretty good deal for a 7" touch screen, HDMI input with USB for the touch feature. I'd like an explanation on the resolution though, it says 800x480 native but somehow it can use up to 1080p? What? I'm sure that's some kind of marketing scam but they do show a screenshot of choosing the resolution and sure enough, it lists up to 1920x1080.

Hi,

Just thought I'd nip to this conversation. We've been doing some dev work and having some good success using the Lilliput FA1011-NP/C/T monitor for our application (interactive taxi advertising). We picked it up from:-

http://www.carcomputer.co.uk/index.php? ... ord=FA1011

Interestingly, it looks the exact same model as the below one:-

http://www.carcomputer.co.uk/index.php? ... spberry+pi

... which they also sell - and they're the same price.

Cheers,

KefrifD

KefrifD - what are you using to talk to the touch screen. I've got a media player setup, but I suspect I'm going to need to start from a more generic kernel :(

HI,

I've just purchased the Lilliput 10.1" touchscreen FA1012-NP/C/T. Following the above info I'm trying to install xinput-calibrator. However when I try to 'install it' by running autogen.sh I get an error saying it can't find the packages: xext or xi.

From searching on line, I've installed xinput and the x11proto-xext-dev, but they aren't being found by the pkg-config.

Has anyone else had this problem, please?

(although mine is marked as 619AT).

HDMI video works out of the box, but with trial and errors I've found the optimal resolution 720x480 using the following settings in "config.txt":
Code: Select all
hdmi_group=1
hdmi_mode=3
hdmi_drive=2
hdmi_ignore_edid=0xa5000080

The touchscreen "eGalax Inc. USB TouchController" works with X without special drivers (although the vendor provides ones in binary form, but only for x86/amd64). I'm running Archlinux, tried with both 3.1.9 and 3.2.27 kernels, xorg-server 1.12.4. However, it is not usable without calibration (the axes are swapped too). I've compiled "xinput_calibrator" from:
http://www.freedesktop.org/wiki/Software/xinput_calibrator
Archlinux AUR:
https://aur.archlinux.org/packages.php?ID=35031

After 2 iterations of calibration I've got the following options to store in "/etc/X11/xorg.conf.d/99-touch-calibr.conf":
Code: Select all
Section "InputClass"
   Identifier   "calibration"
   MatchProduct   "eGalax Inc. USB TouchController"
   Option   "Calibration"   "79 4012 3895 262"
   Option   "SwapAxes"   "1"
EndSection

Thus now the touchscreen works fine. The problem remaining at the moment is the HDMI audio. Principally it works, but there are strange issues I described in the post:
http://www.raspberrypi.org/phpBB3/viewtopic.php?p=178247#p178247

The overall impression of Lilliput HDMI touchscreen monitor is really good.

What did it cost?

I'm interested in the touch overlay, however I can't find one as cheap as you say. Help please?

Has anyone found any touchscreens that are nicely integrated in a headrest for use in a car?

2 touch-screen HDMI monitors combined with 2 Raspberry Pi's sharing an external hard drive with UTP network interface would make a very nice car entertainment system.

Has anyone had any luck with a USB monitor using Displaylink on Rasbian?

Incase anyone is on here in the future heres what i did to get my touchscreen running.

Code: Select all
sudo apt-get install libx11-dev
sudo apt-get install libxext-dev
sudo apt-get install libxi-dev
sudo apt-get install x11proto-input-dev


if any of those fail run update and upgrade and try again

then

download http://github.com/downloads/tias/xinput_calibrator/xinput_calibrator-0.7.5.tar.gz

Code: Select all
 
tar xvzf (downloaded file)
cd (downloaded file)
./configure
make
sudo make install


then

prefrances/calibrate touchscreen


Hello,

Thanks this really helped me. I wanted to make the calibration more permanent but I do not have the directory you are showing .

I mean I do not have the "xorh.conf.d/99.calibration.conf" any Idea why ?

Thanks

I have tried similar but cannot get it to work.
Bluebian, the better Raspbian, okay maybe worse, well...definitely worse.

Hello, I just got my 10" Capacitive touchscreen from chalktech and wrote a small tutorial about it : it seems to work fine for me!

http://pikiosk.tumblr.com/post/41042790814/capacitive-touchscreen-raspberry

PS: Maybe I did something wrong but the LCD makes an awful and annoying noise (an high-frequency whistle that changes with colors )

hints?

Hi!

I am using these parts with Raspbian(with new kernel module) and XBMC(with patches for touchscreens).
Please look at my tutorials to be able to use them:

Another way to think about it is to run a webserver on the Pi and make a decent set responsive design pages for tablets/mobile. Run the webserver to distribute the interface.

I also started looking into this.

I spend some time (and money :) ) over at DealXtreme

http://dx.com/p/i082510-800-x-480-7-tft-touch-screen-module-153336

I came across this unit as an Arduino compatible display, and had seen the similar 2.8" over at Adafruit.

I was wondering how y'all did connecting the 2.8 touch screen, and I'd be more interested in the 7" here... my largest concern is of course driving the video, and then touchscreen is a real "nice to have"

Details of a working 2.8" TFT with touch panel working are outlines throughout this thread :

I love you aragats! It worked nicely (I have the same monitor). I'm still trying to adjust the calibration (xinput does not seem to adjust well, so I'm trying adding/subtracting some random values around the values the xinput gives me. Thanks a lot. I was looking for a solution for more than a week!
