STM32F4_LCD显示汉字

        LCD显示汉字和显示图片、数字、字符的原理是一样的，都是将汉字、图片、数字以及字符转换点阵，进而通过函数扫描点阵在LCD上显示；正点提供汉字取字模软件 PCtoLCD2002完美版；

具体步骤：

        1. 打开取字模软件，设置字模选项；设置完成后点击确认；

        2. 输入汉字，生成字模，然后将生成的字模赋值到 MDK5 中，当然也可以创建一个 .h 文件，主要看个人习惯；

        3. 最重要的是在 LCD.c 文件中写 LCD_ShowChinese 函数，实现在 LCD 上显示汉字的功能；

//参数
//x y 起点坐标
//num 要显示的汉字对应于字库中的数值
//size 要显示的汉字的大小
//mode 对应模式

void LCD_ShowChinese(u8 x,u8 y,u8 num,u8 size,u8 mode)
{
    u8 temp,t,t1;
    u8 y0=y;
    u8 csize=(size/8 + ((size%8)?1:0)) * size;  //16/8+1
    for(t=0;t

        4. 编写相应的主函数

int main(void)
{ 
    
	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();
 	LCD_Init();           //初始化LCD FSMC接口
	POINT_COLOR=BLACK;      //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。
        
    LCD_Clear(WHITE);
 
    //size=16
    LCD_ShowChinese(50,100,3,16,0);                 //螳
    LCD_ShowChinese(50+16,100,4,16,0);              //螂
    LCD_ShowChinese(50+2*16,100,5,16,0);            //捕
    LCD_ShowChinese(50+3*16,100,6,16,0);            //蝉
    LCD_ShowChinese(50+4*16,100,7,16,0);            //，
    LCD_ShowChinese(50+5*16,100,8,16,0);            //岂
    LCD_ShowChinese(50+6*16,100,9,16,0);            //知
    LCD_ShowChinese(50+7*16,100,10,16,0);           //黄
    LCD_ShowChinese(50+8*16,100,11,16,0);           //雀
    LCD_ShowChinese(50+9*16,100,12,16,0);           //在
    LCD_ShowChinese(50+10*16,100,13,16,0);          //后
    LCD_ShowChinese(50+11*16,100,14,16,0);          //！
    
    while(1)
    {
        LED0=!LED0;
        delay_ms(500);
    }
}
