I'm using the kit from
consisting of the TFT-LCD G070Y2-L01 and the Atmel capacitive touch.
When touching the screen I can prompt the mouse pointer to move, i.e. X11 does see touch events.
However, there is an offset of more than 50mm. Frequently also the movement direction deviates to the one of my finger,
i.e. finger moves to the right -> mouse pointer moves down.
During boot the serial log contains the following Atmel related lines:
atmel_mxt_ts 2-004a: Family ID: 128 Variant ID: 1 Major.Minor.Build: 2.0.AA
atmel_mxt_ts 2-004a: Matrix X Size: 16 Matrix Y Size: 14 Object Num: 17
input: Atmel maXTouch Touchscreen as /devices/platform/imx-i2c.2/i2c-2/2-004a/input/input1
For a capacitive touch a calibration should not be necessary. Thus how to get this issue resolved?
