This routine is based on the OLED display routine developed by the Arduino UNO board.

1. Before opening the program, place the font folder in the libraries folder in the arduino root directory.

2. Because the picture displayed by the routine is large, the text is more, and the pictures and texts are all stored in FLASH. Therefore, when displaying pictures or texts, it is necessary to read out the patterns in the FLASH and display them on the display screen, so the display speed is slow.

3. If the user wants to display the content they need, you need to modify the font file in the font folder to add the template you have taken.

4. Please refer to the contents of the ¡°Module Description¡± folder for the mode.

5 Since the company's font chip is GBK coded, it is different from Arduino's UTF-8 encoding, so there is no display with a font.
