- Calibrate the touch screen if the application supports it.
- Verify that the correct firmware for the resistive touch version (DMG80480Y070_02NR) is loaded.
- Problemes de comunicació (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.
