51單片機程序怎么讓void main()里同時進行?

ID:923529 · 發表于 2022-5-26 01:16

代碼如下，這是一個光立方的程序。第一層亮了有短暫的延遲第二層才亮，然后到第三次第四層，有沒有什么辦法讓四層同時亮。

單片機源程序如下:
#include <reg52.h>
#define uchar unsigned char
#define uint unsigned int

sbit SH_CP1 = P1^0;                         //第一層引腳
sbit DS1 = P1^1;
sbit ST_CP1 = P1^2;

sbit SH_CP2 = P1^3;
sbit DS2 = P1^4;
sbit ST_CP2 = P1^5;

sbit SH_CP3 = P1^6;                         //第二層引腳
sbit DS3 = P1^7;
sbit ST_CP3 = P2^0;

sbit SH_CP4 = P2^1;
sbit DS4 = P2^2;
sbit ST_CP4 = P2^3;

sbit SH_CP5 = P2^4;                         //第三層引腳
sbit DS5 = P2^5;
sbit ST_CP5 = P2^6;

sbit SH_CP6 = P2^7;
sbit DS6 = P3^0;
sbit ST_CP6 = P3^1;

sbit SH_CP7 = P3^2;                         //第四層引腳
sbit DS7 = P3^3;
sbit ST_CP7 = P3^4;

sbit SH_CP8 = P3^5;
sbit DS8 = P3^6;
sbit ST_CP8 = P3^7;
