查找开发板资料

由资料可知LED由P1寄存器控制

代码

#include <REGX51.H>
void delay(unsigned int z){ 
	unsigned int x, y;
	for (x = z; x > 0; x--){
		for (y = 114; y > 0; y--){
		
		}
	}
}

void main()
{
	while(1)
	{
		P1_0 = 0;
		delay(200);
		P1_0 = 1;
		P1_1 = 0;
		delay(200);
		P1_1 = 1;
		P1_2 = 0;
		delay(200);
		P1_2 = 1;
		P1_3 = 0;
		delay(200);
		P1_3 = 1;
		P1_4 = 0;
		delay(200);
		P1_4 = 1;
		P1_5 = 0;
		delay(200);
		P1_5 = 1;
		P1_6 = 0;
		delay(200);
		P1_6 = 1;
		P1_7 = 0;
		delay(200);
		P1_7 = 1;
	}	
}
