1. The project of ESP32-Smart-Home-Automation-GUI-Files is not suitable for the screen DMT10768T097_18WT. As this screen is K600+, but the project is suitable for T5L. Besides, the background iamge is 800X480 resolution, so when you download it to screen, the screen was blurred (the background images must be BMP format, 24 bit color and the resolution is same with the screen).

2. The project of 1024768 is correct, pls kindly format your SD card followed by below picture. Then download this project again.

3. After downloading the project 1024768, pls kindly click the area cicrled in below picture to see if the buzzer sounds and switch the page. If not, pls kindly calibrate the screen followed by below picture (kindly note that if the screen calibration is completed, you will hear a long beeping sound from the buzzer after clicking on the calibration + cursor).

DMT10768T097_18WT this screen has two kinds of communication level.
If you use RS232, kindly note that RX/TX should be cross wired and the power GND & signal GND should be grounded together.
If you use RS485, kindly connect A to A, B to B.
The communication level should be kept consistant, pls kindly check if the wiring is correct. You can use the attached serial port assistant tool to send the reading version command "5A A5 03 81 0001" to see if there is correct data back.
