簡單流水燈實驗- #include<reg51.h>
- #include<intrins.h>
- #define uchar unsigned char
- #define uint unsigned int
-
- void delayms(uint n)
- {
- uint i=0,j=0;
- for(i=0;i<n;i++)
- {
- for(j=0;j<125;j++);
- }
- }
- void main()
- {
- uchar temp1=0x80;
- uchar temp2=0x01;
- while(1)
- {
- temp1=_crol_(temp1,1);
- P1=~temp1;
- temp2=_cror_(temp2,1);
- P2=temp2;
- delayms(500);
- }
- }
