0.96寸OLED在STM32f103上实现滚动显示长字符

• 一、OLED屏的滚屏命令
• 二、对需要显示的文字进行取模
• 三、修改程序代码
• 四、烧录运行结果
• 五、总结
• 六、参考文献

• 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

• 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);
}

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。
