  Hello @DougWaterford ,

  Please check if the board setting is the as follows:

  

  
  

  And may I kindly ask which display drive you use? Is it Arduino_GFX or LovyanGFX? If it's Arduino_GFX, the version of esp32 package should be 2.0.3. Please refer to:

  ESP32 HMI Demo Code Updated - compatible with new version of esp32 package

  ElecrowDec 1, 2023

  When we first edited the demo code, we based it on the 2.0.3 version of the esp32 package, which resulted in compilation errors for many users who installed the new version of esp32. To solve this problem, we updated the esp32 demo code. The updated content is as follows:

  For 5-inch esp32 screen:

  Modify the following code

  into

  Arduino_RPi_DPI_RGBPanel *lcd = new Arduino_RPi_DPI_RGBPanel(
    bus,
    800 /* width */, 0 /* hsync_polarity */, 210 /* hsync_front_porch */, 4 /* hsync_pulse_width */, 43 /* hsync_back_porch */,
    480 /* height */, 0 /* vsync_polarity */, 22 /* vsync_front_porch */, 4 /* vsync_pulse_width */, 12 /* vsync_back_porch */,
    1 /* pclk_active_neg */, 16000000 /* prefer_speed */, true /* auto_flush */);
  #endif /* !defined(DISPLAY_DEV_KIT) */
  

  For 7-inch esp32 screen:

  Step 1: Download the LovyanGFX library

  https://forum.elecrow.com/uploads/893/XTEWU22K7BIT.png

  Step 2: Modify the code of HMI-7.0

  Add the following code:

  #define LGFX_USE_V1

        cfg.hsync_back_porch  = 40;
        
        cfg.vsync_polarity    = 0;
        cfg.vsync_front_porch = 1;
        cfg.vsync_pulse_width = 31;
        cfg.vsync_back_porch  = 13;

        // Apply configuration to the RGB bus instance.
        _bus_instance.config(cfg);
      }
  
  
      // Configure the panel.
      {

      // Set the RGB bus and panel instances.
      _panel_instance.setBus(&_bus_instance);
      setPanel(&_panel_instance);
    }
  };
  LGFX lcd;

  Step 3: Use the quick search function(Ctrl+F) to replace lcd-> in the code with lcd.

  The Arduino settings are the same as your example except I am using the USB connection.

  I am trying to run the example in the ELCROW tutorial "A7.0 Touch.ino" see in bold.

  Note neither the A7.Touch.ino or the "touch.h" included library file call Arduino_GFX or LovyanGFX.

  A7.0 Touch

  #include "touch.h"

  void setup() {

   // put your setup code here, to run once:

   Serial.begin( 115200 ); /*初始化串口*/

   touch_init();

  }

  void loop() {

   // put your main code here, to run repeatedly:

   if (touch_has_signal())

   {

     if (touch_touched())

     {

       Serial.print( "Data x :" );

       Serial.println( touch_last_x );

       Serial.print( "Data y :" );

       Serial.println( touch_last_y );

     }

   }

  I have tested the USB-Arduino connection with ESP32 DEV1 board no problems. I have a second unit but am reluctant to use it in case i have the same these were both purchased from ELCROW the last month.

  After a sometime and in desperation I tried a higher upload baud rate and it worked I had been using 921600 and 115200 but then tried 230400 with success.
