单片机学习day2（点亮数码管）

1. 点亮数码管代码

#include <reg51.h>


void Delay(unsigned int n)
{
	while (--n);
}

int main(void)
{
	const unsigned char a[10] = {0X3F, 0X06, 0X5B, 0X4F, 0X66, 0X6D, 0X7D, 0X07, 0X7F, 0X6F};
	int i = 0;

	P1 = 0;
	P1 |= (1 << 1);
	P0 = 0;

	for (i = 0; i < 10; i++)
	{
		 P0 = a[i];
		 Delay(0xffff);	
	}

	return 0;
}
