    • Problems using lvgl with touchscreen

      I ported the lvgl8 arduino to my core2 today, it can run the lvgl_demo_benchmark in 39fps, the touch was fuction too.
      Then I tried to put the lvglhandler into a task by freertos (it was in loop before), with priority 3. It worked as well.

      So I put some other task in my code, the first one is a blink (by using m5.apx.setled and vtaskdelay), It worked too. Then I tested it with demos of benchmark, music and widgets. And blink task, lvgl and touch fuction were all normal.

      Seems everything went well, I changed the blink task into serial.println sth per 1s. Then I tested those 3 demos again, I found that the serial task worked well, lvgl worked well, but the touch funtion didn't worked. The serial task is sending thing every seconds normally, but i cant move the screen by touching in those demos, lvgl is working cus in benchmark demo, every tests is going but i cant move the screen to see the marks at the end of the demo.

      So I try change the task back to blink, the touch function again. Seems it's sth about serial affect the touch function? But i dont know why.
      Part of my code:

      Task of blink or serial:

      void Taskblink( void *pvParameters )
      {
      for(;;)
      {
      M5.Axp.SetLed(1);
      vTaskDelay(800);
      M5.Axp.SetLed(0);
      vTaskDelay(800);
      // Serial.println("i'm good..");
      // vTaskDelay(1000);
      }
      }

      Task of lvglhandler:

      void Tasklvglhandler( void pvParameters )
      {
      for(;;)
      {
      lv_timer_handler(); /
      let the GUI do its work */
      vTaskDelay(5);
      }
      }

      lvgl touchpad read recall
      void my_touchpad_read( lv_indev_drv_t * indev_driver, lv_indev_data_t * data )
      {
      TouchPoint_t coordinate;
      M5.Touch.getPressPoint();

      if (!M5.Touch.ispressed()){
          data->state = LV_INDEV_STATE_REL;
      } else {
          data->state = LV_INDEV_STATE_PR;
          /*Set the coordinates*/
          coordinate = M5.Touch.getPressPoint();
          data->point.x = coordinate.x;
          data->point.y = coordinate.y;
      }
      

      }

      Thanks for helping.
