單片機源程序如下:
- #include<reg51.h>
- unsigned char zz[]={0x01,0x03,0x02,0x06,0x04,0x0c,0x08,0x09};
- unsigned char fz[]={0x09,0x08,0x0c,0x04,0x06,0x02,0x03,0x01};
- void delay(unsigned ms)
- {
- unsigned int t;
- while(ms--)
- {
- for(t=0;t<120;t++)
- {
- }
- }
- }
- void delay_2(unsigned int i)
- {
- if(P1==3)
- {
- while(--i);
- }
- }
- void main()
- {
- unsigned int speed;
- unsigned int i;
- P1=0;
- speed=60;
- while(1)
- {
- if(P1==1)
- {
- for(i=0;i<8;i++)
- {
- P2=fz[i];
- delay(speed);
- }
- delay_2(10);
- }
- if(P1==2)
- {
- for(i=0;i<8;i++)
- {
- P2=zz[i];
- delay(speed);
- }
- delay_2(10);
- }
- }
- }
如果兩個開關同時關閉電機停止轉動就會，請問怎么辦
