1. Use a jpg/BMP file to create the background picture or the icon files.
2. Add different function blocks as data display, text display, variable icon display, data input on the different areas.
3. Assign a variable memory address to each function block (128KB variable memory space in total).
4. Compile and download the whole project file through the USB interface on the display.
The Graphic LCD Display Module is using UART interface to communicate. And the protocol is using customized command sets.
