          +## Demo Code Overview

          +

          +1. **Demo_CH552_Project_Template**  

          +   - This is a project template program without any peripheral code. Use it as a base to create your own project.

          +

          +2. **IPS Screen Example Codes (8 Sizes Available)**  

          +   - For each IPS screen size, there are four demo examples:

          +     - **A. Demo_CH552_Clear_Screen**  

          +       Demonstrates solid color fill. Displays five colors: black, white, red, green, and blue.

          +     - **B. Demo_CH552_Show_Font**  

          +       Demonstrates text and symbol display. Shows Chinese, English, numbers, and symbols.

          +     - **C. Demo_CH552_Show_Graph**  

          +       Demonstrates graphics display. Shows lines, dots, rectangles, circles, triangles, and black-and-white checkerboard patterns.

          +     - **D. Demo_CH552_Show_Picture**  

          +       Demonstrates image display. Shows a full-screen 40x40 pixel image.

          +

          +3. **HEX File Directory**  

          +   - Contains compiled HEX files for all 8 IPS screen sizes.  

          +   - No need to search for HEX files in the example projects; simply use USB or serial to download the HEX files from this directory.  

          +   - For detailed download instructions, refer to the documentation in the "Download Methods" folder of the resource

	32	+## Demo Code Overview
	33	+
	34	+1. Demo_CH552_Project_Template
	35	+ - This is a project template program without any peripheral code. Use it as a base to create your own project.
	36	+
	37	+2. IPS Screen Example Codes (8 Sizes Available)
	38	+ - For each IPS screen size, there are four demo examples:
	39	+ - A. Demo_CH552_Clear_Screen
	40	+ Demonstrates solid color fill. Displays five colors: black, white, red, green, and blue.
	41	+ - B. Demo_CH552_Show_Font
	42	+ Demonstrates text and symbol display. Shows Chinese, English, numbers, and symbols.
	43	+ - C. Demo_CH552_Show_Graph
	44	+ Demonstrates graphics display. Shows lines, dots, rectangles, circles, triangles, and black-and-white checkerboard patterns.
	45	+ - D. Demo_CH552_Show_Picture
	46	+ Demonstrates image display. Shows a full-screen 40x40 pixel image.
	47	+
	48	+3. HEX File Directory
	49	+ - Contains compiled HEX files for all 8 IPS screen sizes.
	50	+ - No need to search for HEX files in the example projects; simply use USB or serial to download the HEX files from this directory.
	51	+ - For detailed download instructions, refer to the documentation in the "Download Methods" folder of the resource
