Touch screen calibration in Android

trongthinh — Fri, 17 May 2019 09:55:23 GMT

I am working on iMX8mq-evk with an LCD touch screen. Touch panel is working but it needs to be calibrated. How to calibrate a touch screen in Android OS? Is there any tool?

I use android source code from NXP at https://www.nxp.com/webapp/Download?colCode=O8.1.0_1.3.0_ANDROID_SOURCE_8MQ_GA&appType=license&location=null
