Description:This article defines a picture control. The OLED screen is a monochrome screen, so this picture control supports monochrome BMP images. converting a normal image to a monochrome picture can be BmpCvt.exe with a tool. Convert the converted BMP image to hex file, can be used Bin2C.exe. Both of these tools are emwin self-bringing tools.

Source:

The converted hex file is then organized into the following example format:

Battery0.c
