【51单片机LED闪烁10次数码管显示0-9】2023-12-14

缘由stc89c52代码_编程语言-CSDN问答

stc89c52rc用定时器方式一写一个LED

灯闪烁十次数后码管从0加到10

#include "reg52.h"
unsigned char code SmZiFu[]={63,6,91,79,102,109,125,7,127,111,128,0};//共阴0-9.
void main()
{//缘由https://ask.csdn.net/questions/8044538
	unsigned char sy=0,my=0,ys=0,xd=0,ls=0,js=0;
	while(1)
	{
		if(++sy==0)if(++my==0)
		{
			P0=ls%2;if(++ls==20)ls=js=0;
			P1=SmZiFu[js];if(ls%2)++js;
		}
