电阻屏NS2009
tslib OK,ts_calibrate,ts_test可以正常运行。
littlevgl demo可以正常显示，但是，触摸 错误输出“ input input1: Poll touch data failed: ”

lv_indev_drv_t indev_drv;
lv_indev_drv_init(&indev_drv); /Basic initialization/
evdev_init();
indev_drv.type = LV_INDEV_TYPE_POINTER; /See below./
indev_drv.read = evdev_read; /See below./
lv_indev_drv_register(&indev_drv); /Register the driver in LittlevGL/
。。。
/Handle LitlevGL tasks (tickless mode)/
while(1) {
lv_tick_inc(5);
lv_task_handler();
usleep(5000);
}

哪里配置还有问题
