Instructions for use:

1. Firstly, upload the program (github.com/Xinyuan-LilyGO/T-Display-S3/tree/main/firmware)

2. The board uses USB as the JTAG upload port.

When printing serial port information on USB_CDC_ON_BOOT configuration needs to be turned on.

If the port cannot be found when uploading the program or the USB has been used for other functions, the port does not appear.

• Please enter the upload mode manually.

1. Connect the board via the USB cable
2. Press and hold the BOOT button , While still pressing the BOOT button, press RST
3. Release the RST
4. Release the BOOT button
5. Upload sketch

NOTE:

1. The program can be written normally, but there is still no display after writing.

• There are factory test files in the firmware folder, which can be flashed into the board to check whether the board is normal.

If there is still no display, then it can be judged that there is a problem with the board or the screen.

• Delete the ( TFT_eSPI ) in the libraries, and replace the ( TFT_eSPI ) in the folder of the main page to the libraries directory
• When opening the Arduino IDE, it prompts whether to upgrade the library, please choose not to upgrade, otherwise it will overwrite the configuration of the ( TFT_eSPI ) display

2. The factory sample program includes steps for connecting to WiFI

Due to the need to increase the power of the chip when searching for WiFi signals, it is normal for the chip to generate heat

When you connect to WiFi or after the program runs, the search will stop and the normal operating temperature will be restored
