A13_OLinuXino added touchscreen GSL1680，it workesbut it cannot calibrate ?

[Guess0God1]

I have compiled A13-SDK Android 4.1 JB which is downloaded from OLIMEX,it can work.Then I added touchscreen gslX1680 which is from www.linux-sunxi.com,the gslX1680 drive program runs on the system too,but it can't calibrate completely.When boots up,it keeps on
calibrating all the way.It cannot quit.Then i find a TSCalibration2.apk in sysytem/app,i delete it.It does not hint me to calibrate
any more,which take a new problem,the gslX1680 cann't calibration.I think about for a few days,it seems i have nothing to do on it.
so who can help me out?thanks thanks.

From what I have gathered in using 2 different cap touch LCD displays is that they don't require any calibration.

The panel is factory calibrated and should output coordinates based on it's internal resolution. My panel is 1500 x 900 but works with a 800x480 LCD. Android takes care of the scaling.

What are you seeing when you touch the screen? Use a mouse to enable the debugging tools for the touch so you can see where Android thinks you are touching.

I see from you FEX settings that the Y is inverted. Is this correct?

My board cannot connect with a mouse.That i cannot calibrate with a mouse. I  only calibrate through touch the touchsreen.Can you give some ideas for me?i feel that i should change the usb event to touchsreen event.But i could not make sure i should alter what file.can you give me some advices.Thanks !

Don't you have a spare USB port to plug a mouse into? It would be good to do this as it will allow you to set the debugging and show touches so you can see where the OS believes you are touching.

You talk about USB but the info below shows the touch is via I2C.

There is a short post that explains Calibration2.apk, maybe it helps you or sb else: http://www.androidsoldier.com/2015/01/how-to-fix-touch-screen-on-android.html
