Hello, currently i am working on GT911, 7 inch touchscreen for OrangePi
Plus2E, i can successfully work with I2C bus with no problem and
successfully assigned INT and RST pins and touches are being detected but
it is reporting wrong X/Y values.
I am using this driver from GOODIX
https://github.com/goodix/gt9xx_driver_android
I am using this configuration array which is 800*480 and i want this
resolution, max X value is reaching 360 and Y is 600, I tried to manipulate
the second to fifth Byte values which are responsible for X/Y axis
resolutions but with no luck.
here is my array, i would be glad if i got some help, many thanks.
