IR Touch Frame calibration

A Former User

@cowboysdude But somebody might have bigger mirror and frame than real screen size, and his touch-solution should be upon the mirrorglass. In that case he need calibration to adjust.

actually for some reason it is now working!

@cyberphox I just purchased the IR Touch Frame for my MagicMirror but can’t change it from Landscape to Portrait. How did you manage to calibrate yours? I have a 40" frame. Any help appreciated!

Xinput calibrator should help

peemoeller

@cyberphox thanks! Are you able to point me on how to make the adjustments? I have xinput installed but not sure where to go from here.
Thanks for your help!

cyberphox

run the calibration from the menu…touch the points and that’s it!

@cyberphox Hi there, ok! I now managed to get my IR Touch Overlay set to portrait! also just finished running the xinput touch calibrator program under ‘Preferences’ (it had me touch the 4 red crosses). It shows:

< Calibrating standard Xorg driver “Multi touch overlay device” current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
If these values are estimating wrong, either supply it manually with the - -precalib option, or run the ‘get_precalib.sh’ script to automatically get it (through HAL). >

My issue, I find the curser doesn’t reach the the edges of my monitor. Example I can’t simply click on the Raspberry Icon in the corner. The curser is diaginally 2 inches away? I have a 42 inch IR Touch Overlay using a 32 inch LCD monitor.

Where can I set or adjust this? Any thoughts?

Fun!

i ask the same question my bro

mple I can’t simply click on the R

So, has anyone found a solution for this?
I have a 32 inches mirror (and 32 inches touch frame) in a 18 inches screen. Since the touchframe is bigger than the screen i couldn’t find a way to calibrate it to just work on the 18 inches screen area (as I do when I calibrate it on Windows).

Does anyone have any thoughts on how to do this?

Thanks.

Here is a few more information.

The picture below shows my mirror (with the 18’’ screen) and the 32’’ touch frame above it.
(This is just a test mirror, that’s why the touch frame doesn’t match the mirror frame. And just ignore the painted part… it’s just some information i can’t share)

Before calibrating it, the 18’’ screen is “mapped” to the whole 32’’ touch frame. That’s expected.

What I need to do is calibrate it so the only part of the touch frame that will recognize the touch is the area of the 18’’ screen.

I run the command

DISPLAY=:0.0 xinput_calibrator

Then I calibrate the screen, like the picture below (clicking the four points)

The output of the command is:

Calibrating standard Xorg driver "Touch Device FC315WH00DL-CT-B2-20P"
        current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
        If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL).


--> Making the calibration permanent 
  copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'
Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "Touch Device FC315WH00DL-CT-B2-20P"
        Option  "MinX"  "8770"
        Option  "MaxX"  "46111"
        Option  "MinY"  "5539"
        Option  "MaxY"  "40880"
EndSection

But nothing changes… when I touch the screen again, the same thing is happening: the 18’’ screen is “mapped” for the whole 32’’ touchframe, not just the area of the 18’’ screen.

I tried saving the code above both on /etc/X11/xorg.conf.d/99-calibration.conf and modifying the values of Min/Max X/Y (like changing from 46111 to 2000) but absolutely nothing changes… I think the touchframe is not using these values for anything.

When I use the same touchframe on windows and use the calibration tool, it map my 21’’ PC monitor correctly for the 32’’ touch frame.

I’ve been struggling with this for a few days and I see that a lot of people is having/had the same problem. Does anyone know a solution for this?

Thanks.
