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

但是触摸不对啊，和画面对不上？
另外，这个怎么使用 tslib校准好的数据？ /dev/input/event1--这个输出已经校准了吗？

tslib OK,ts_calibrate,ts_test可以正常运行。
这个需要怎么在LitlevGL中调用？
