第十一届蓝桥杯嵌入式组别底层驱动程序-流水灯

太难了，这个io操作的太难了
正流水和反流水，花样灯也按照下面的改也行。。。。。。太麻烦了。

void LED_cycle(uint8_t mode)
{
    
    
		if(mode)//灯效模式
		{
    
    
			switch(LedTiming /125%10)
						{

								case 1:   LED_Control(LED2,0);  LED_Control(LED1,1);    break;

}

void LED_cycle(uint8_t mode);

//主函数里面
		LED_Control(LED_All,1);//全灭
		if(led_flag == 1)LED_cycle(1,0);//按键控制led_flag数值。
		if(led_flag == 2)LED_cycle(1,1);

//一个简单的延时
