一、OLED屏的滚屏命令

• 水平左右移

OLED_WR_Byte(0x2E,OLED_CMD);        //关闭滚动
OLED_WR_Byte(0x26,OLED_CMD);        //水平向左或者右滚动 26/27
OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
OLED_WR_Byte(0x00,OLED_CMD);        //起始页 0
OLED_WR_Byte(0x07,OLED_CMD);        //滚动时间间隔
OLED_WR_Byte(0x07,OLED_CMD);        //终止页 7
OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
OLED_WR_Byte(0xFF,OLED_CMD);        //虚拟字节
OLED_WR_Byte(0x2F,OLED_CMD);        //开启滚动

二、对需要显示的文字进行取模

  "晓",0x00,0x80,0x00,0x80,0x78,0xBC,0x4B,0xC0,0x48,0x50,0x48,0x24,0x48,0xD4,0x7B,0x0C,
  0x48,0x00,0x4B,0xFE,0x48,0x90,0x48,0x90,0x79,0x12,0x49,0x12,0x02,0x0E,0x04,0x00,/*"晓",0*/
  "看",0x00,0xF8,0x7F,0x00,0x01,0x00,0x3F,0xF8,0x02,0x00,0xFF,0xFE,0x04,0x00,0x08,0x00,
  0x1F,0xF0,0x28,0x10,0x4F,0xF0,0x88,0x10,0x0F,0xF0,0x08,0x10,0x0F,0xF0,0x08,0x10,/*"看",1*/
  "天",0x00,0x00,0x3F,0xF8,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0xFF,0xFE,0x01,0x00,
  0x02,0x80,0x02,0x80,0x04,0x40,0x04,0x40,0x08,0x20,0x10,0x10,0x20,0x08,0xC0,0x06,/*"天",2*/
  "色",0x08,0x00,0x08,0x00,0x1F,0xE0,0x20,0x20,0x40,0x40,0xBF,0xF8,0x21,0x08,0x21,0x08,
  0x21,0x08,0x3F,0xF8,0x20,0x00,0x20,0x02,0x20,0x02,0x20,0x02,0x1F,0xFE,0x00,0x00,/*"色",3*/
  "暮",0x04,0x40,0x7F,0xFC,0x04,0x40,0x1F,0xF0,0x10,0x10,0x1F,0xF0,0x10,0x10,0x1F,0xF0,
  0x04,0x00,0xFF,0xFE,0x10,0x10,0x2F,0xE8,0xC8,0x26,0x0F,0xE0,0x08,0x20,0x0F,0xE0,/*"暮",4*/
  "看",0x00,0xF8,0x7F,0x00,0x01,0x00,0x3F,0xF8,0x02,0x00,0xFF,0xFE,0x04,0x00,0x08,0x00,
  0x1F,0xF0,0x28,0x10,0x4F,0xF0,0x88,0x10,0x0F,0xF0,0x08,0x10,0x0F,0xF0,0x08,0x10,/*"看",5*/
  "云",0x00,0x00,0x3F,0xF8,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xFF,0xFE,0x02,0x00,
  0x04,0x00,0x04,0x00,0x08,0x40,0x10,0x20,0x20,0x10,0x7F,0xF8,0x20,0x08,0x00,0x08,/*"云",6*/

三、修改程序代码

• main函数：

int main(void)
{	
	delay_init();	    	       //延时函数初始化	  
	NVIC_Configuration(); 	   //设置NVIC中断分组2:2位抢占优先级，2位响应优先级 	
	OLED_Init();			         //初始化OLED  
	OLED_Clear(0);             //清屏（全黑）
	OLED_WR_Byte(0x2E,OLED_CMD);        //关闭滚动
    OLED_WR_Byte(0x27,OLED_CMD);        //水平向左或者右滚动 26/27
    OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
	OLED_WR_Byte(0x00,OLED_CMD);        //起始页 0
	OLED_WR_Byte(0x07,OLED_CMD);        //滚动时间间隔
	OLED_WR_Byte(0x07,OLED_CMD);        //终止页 7
	OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节
	OLED_WR_Byte(0xFF,OLED_CMD);        //虚拟字节
	TEST_MainPage();
	OLED_WR_Byte(0x2F,OLED_CMD);        //开启滚动

}

• 显示数据函数

void TEST_MainPage(void)
{	
	GUI_ShowCHinese(10,20,16,"晓看天色暮看云",1);
	delay_ms(1500);		
	delay_ms(1500);
}

四、烧录运行结果

五、总结

本次实验相比上次多出了让数据滚动的功能，主要差别在主函数中的代码，其他的和上次实验几乎相同。
