the issue resolved after change EVDEV_NAME to be "/dev/input/event4" in lv_drv_conf.h

But there is nothing show after ./demo, event any message.

my evtest show as below: evtest No device specified, trying to scan all of /dev/input/event* Not running as root, no devices may be available. Available devices: /dev/input/event0: Telink Wireless Receiver Mouse /dev/input/event1: Telink Wireless Receiver Consumer Control /dev/input/event2: Telink Wireless Receiver System Control /dev/input/event3: Telink Wireless Receiver /dev/input/event4: Logitech USB Optical Mouse
