8. Troubleshooting
This section addresses common issues you might encounter with your ELEGOO 2.8 Inch TFT Touch Screen.
- Q1: How to power the screen?
- This screen can be powered directly by the UNO or 2560 motherboard using a USB-A to B port cable; no additional power supply is required.
- Q2: Why is the 2.8-inch TFT screen not working?
- Please use Example01-Simple test to check the screen first. This code file does not use any library files. If this code file makes the screen work correctly, there might be a library file issue. If the screen still does not work, it may be defective. Please send us a photo showing the connection between the 2.8-inch screen and the controller board, and we will assist you in resolving the issue.
- Q3: The touch function of the 2.8-inch TFT screen is not working?
- Please try downloading the following code to the control board: drive.google.com/file/d/1wps9b6sMZNwhEfTe6SEEvCfTFbGid5lL/view?usp=share_link. When you touch the screen, it will display the X-axis, Y-axis, and touch pressure values. The X-axis value ranges from approximately 1000 to 100 from left to right. The Y-axis value ranges from approximately 100 to 1000 from top to bottom. Please contact us if you continue to experience issues.
- Q4: How to turn off the backlight of the 2.8-inch TFT screen?
- The backlight circuit is directly connected to the 5V and GND pins of the PCB. The backlight can only be turned off by cutting the power supply.
