FAQ

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

   1. 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
   2. Delete the <TFT_eSPI> in the libraries, and replace the <TFT_eSPI> in the folder of the main page to the libraries directory
   3. 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 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

3. If the above is invalid, burn the binary file to check whether the hardware is normal
