  • [RPi] Rotating TFT Touchscreen (MPI5001)

    i created an account just to say :

    meinnamehier thank you so much!

    i had the calibration issue, i did your fix and it worked ! (using 10" touchscreen on raspbian)

    - Create a file like "99-touchscreen.rules" in /etc/udev/rules.d/

    - enter:

    Code
    SUBSYSTEM=="input", ATTRS{name}=="QDtech MPI5001", KERNEL=="event*", ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 1 -0.1"

    - then, do the reinit and test :

    Code
    udevadm hwdb --update
udevadm trigger /sys/class/input/event2
udevadm test /sys/class/input/event2


    fixed! :)
