Description

 

 

Mini DGUS DWIN screen debugging tools to support PC debug mode (only need a usb to serial line), and CPU debug mode.

Usage 1 :   the PC and DWIN screen communications debugging.

Steps: 1. The DWIN screen and debugging board FFC 10pin cord connected together

      2. In the PC side with a usb to serial cable connected to debug board DB1 interface

          3. In the P3 power supply interface, the access 5V power supply.

          4. Access 5V after power, you should see DWIN screen is lit, you can now in the PC via the serial debugging assistant or other serial tool, debugging the screen DWIN.

         5. Further commissioning can transmit and receive indicator panel to see if there is a physical connection problem.

        6. Communication Command Example: (16 hex ) 5A A5 04 80 03 00 05  

After sending the command, you can switch from another page to page 5.

 

 

Use Method 2 : Microcontroller and DWIN screen communications debugging. 

Steps: 1. The DWIN screen and debugging board FFC 10pin cord connected together

      2. In the P2 at the microcontroller interface access to power and communication pins (Note that certain communication output is TTL level).

      3. After the physical connection, you should see DWIN screen is lit, you can now control panel in the DWIN through the microcontroller serial commands.

         5. Further commissioning can transmit and receive indicator panel to see if there is a physical connection problem.
