I have few doubts regarding the values obtained after calibrating an Yocto based system and running the evtest program running on the same system.
I calibrated the touch screen using the xinput_calibrator and obtained the following values:
Option "Calibration" "219 3879 172 4087"
Here Minimum x is 219, Maximum x is 3879 ,Minimum y is 172 and Maximum y is 4087
After that I executed the evtest and obtained the following values
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 330 (BTN_TOUCH)
Event type 3 (EV_ABS)
Event code 0 (ABS_X)
Event code 1 (ABS_Y)
Event code 24 (ABS_PRESSURE)
Both the tests give the values for Minimum and maximum X and Y values. But both results are entirely different.
Any one who can help on this?
