The 16 binary data that is stored in the text file is garbled and needs to be read with the 16 binary editing tool, and the default BMP picture reads the book order from the bottom left corner, so when the display on the TFT, you need to pay attention to start scanning from the lower left corner, or first convert the data to the upper left corner to start the order.
