Operating Instructions
The DWIN HMI display module is designed for intuitive graphical user interface (GUI) operation. The specific functions and interactions will depend on the application program loaded onto the module. However, general operating principles include:
Basic UI Interaction
- Touch Control: For resistive touch panel versions (DMG80480Y070_02NR), interact directly with the screen using a finger or stylus.
- Navigation: Tap on icons or buttons to navigate through different screens or activate functions.
- Data Input: Utilize on-screen keypads or input fields for numerical or textual data entry.
- Brightness Adjustment: Adjust screen brightness via the settings menu, typically offering 64 (TA system) or 100 (DGUSⅡ system) levels.
Functional Overview

Working Principle
The DWIN Smart TFT Display with its integrated CPU communicates with an external Microcontroller Unit (MCU) via UART (Universal Asynchronous Receiver-Transmitter) instructions. The MCU then controls various equipment based on the commands received from the display module.
Maintenance
- Cleaning the Screen: Use a soft, lint-free cloth slightly dampened with water or a specialized screen cleaner. Avoid harsh chemicals, abrasive materials, or excessive moisture.
- Environmental Conditions: Operate and store the module within the specified working and storage temperature/humidity ranges to ensure longevity.
- Firmware Updates: Periodically check the DWIN developer forum or official website for firmware updates that may improve performance or add new features. Follow the provided instructions carefully for any updates.
Troubleshooting
- No Display/Power:
- Ensure the power supply is connected correctly and provides the specified voltage (7.0V to 15.0V, typical 12.0V).
- Check all cable connections, especially the 8Pin_2.0mm User Interface socket, for secure fit.
- Verify that the backlight is not set to minimum brightness or turned off in the settings.
- Touch Screen Unresponsive (Resistive Touch Models):
- Ensure the TP interface cable is securely connected.
- Calibrate the touch screen if the application supports it.
- Verify that the correct firmware for the resistive touch version (DMG80480Y070_02NR) is loaded.
- Communication Issues (UART):
- Check the UART mode jumper setting (ON=N81, 5V TTL/COMS; OFF=N81, RS232) matches your MCU's configuration.
- Verify the baud rate settings on both the display module and your MCU are identical.
- Ensure TX and RX lines are correctly connected (TX of one device to RX of the other).
- Software/Firmware Related Problems:
- If the display is not functioning as expected after initial setup, ensure the program has been correctly updated to the LCD module.
- Refer to the DWIN developer forum or technical support for specific software-related issues.
User Tips
- Pre-Assembly Programming: Always update the display module with your application program and test it thoroughly before integrating it into your final product. This prevents potential issues during assembly.
