实验现象

主程序

int main(void)
{ 
 	u8 x=0;
	u8 lcd_id[12];				//存放LCD ID字符串
	NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//设置系统中断优先级分组2
	delay_init(168);      //初始化延时函数
	uart_init(115200);		//初始化串口波特率为115200
	
	LED_Init();					  //初始化LED
 	LCD_Init();           //初始化LCD FSMC接口
	POINT_COLOR=RED;      //画笔颜色：红色
	sprintf((char*)lcd_id,"LCD ID:%04X",lcddev.id);//将LCD ID打印到lcd_id数组。				 	
  	while(1) 
	{		 
		switch(x)
		{
			case 0:LCD_Clear(WHITE);break;
			case 1:LCD_Clear(BLACK);break;
			case 2:LCD_Clear(BLUE);break;
			case 3:LCD_Clear(RED);break;
			case 4:LCD_Clear(MAGENTA);break;
			case 5:LCD_Clear(GREEN);break;

			case 7:LCD_Clear(YELLOW);break;
			case 8:LCD_Clear(BRRED);break;
			case 9:LCD_Clear(GRAY);break;

			case 11:LCD_Clear(BROWN);break;
		}
		POINT_COLOR=RED;	  
		LCD_ShowString(30,40,210,24,24,"Explorer STM32F4");	
		LCD_ShowString(30,70,200,16,16,"TFTLCD TEST");

}

TFTLCD彩屏初始化程序

这一处略，直接调用函数库即可
