I wonder calibrating a capacitive touchscreen(gt911) by using TSLIB.

Hello. I use a Beaglebone Black. ( Debian 3.8.13-xenomai r84)
I am porting 7 inch capacitive touchscreen LCD G Type. (waveshare, Touch Controller : Goodix GT911)

I successfully ported LCD and Device Driver + Device Tree for ‘GT911’ Touch Controller.

I want to calibrate my touchscreen becourse of using my team’s QT application.

So, I wonder calibrating the capacitive touchscreen by using TSLIB.
Help me.

p.s: I installed QT4 into my BBB.
