Touch screen calibration

• This LCD can be calibrated using a program called xinput_calibrator
• Install it with the commands:

cd Elecrow-LCD35

sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb

• Click the Men button on the task bar, choose Preference -> Calibrate Touchscreen.
• Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
• You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).

/ect/X11/xorg.conf.d/99-calibration.conf

• Save the touch parameters (may differ depending on LCD) to 99-calibration.conf, as shown in the picture:
