    使用方法：
        1、在KEIL下编译后烧录到开发板，通电
        2、LCD全亮全灭
        
4、注意事项
    此demo会导致SWD引脚被复用，可以在LCD_GPIO_Init中屏蔽PA13/PA14的复用

	Usage:
	1. After compiling under KEIL, burn to the development board and power on
	2. LCD all on and all off
        
4. Matters needing attention
	This demo causes the SWD pin to be multiplexed, you can block PA13/PA14 multiplexing in LCD_GPIO_Init
