有用的可以看看
单片机源程序如下:
- #include "reg51.h"
- unsigned char code led[]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90};//0-9的字形码
- void delay(unsigned char n);
- int main(void)
- {
- unsigned char i;
- while(1)
- {
- for(i=0;i<10;i++)
- {
- P0=led[i];
-
- delay(200);
- }
- }
- }
- void delay(unsigned char n) //延时子函数;
- {
- unsigned char i,j;
- for(i=0;i<n;i++)
- for(j=0;j<n;j++);
- }
