步进电机的几种驱动方式，与简单例子！

1. 
   
2. [indent]C：
   
3. 
   
4. #include <REG2051.H>.
   
5. #define stepper P1
   
6. void delay();
   
7. 
   
8. void main(){
   
9. while(1){
   
10. stepper = 0x0C;
    
11. delay();
    
12. stepper = 0x06;
    
13. delay();
    
14. stepper = 0x03;
    
15. delay();
    
16. stepper = 0x09;
    
17. delay();
    
18. }
    
19. }
    
20. 
    
21. void delay(){
    
22. unsigned char i,j,k;
    
23. for(i=0;i<6;i++)
    
24. for(j=0;j<255;j++)
    
25. for(k=0;k<255;k++);
    
26. }
    
27. 
    
28. 汇编：
    
29. org 0H
    
30. 
    
31. stepper equ P1
    
32. 
    
33. main:
    
34. mov stepper, #0CH
    
35. acall delay
    
36. mov stepper, #06H
    
37. acall delay
    
38. mov stepper, #03H
    
39. acall delay
    
40. mov stepper, #09H
    
41. acall delay
    
42. sjmp main
    
43. 
    
44. delay:
    
45. mov r7,#4
    
46. wait2:
    
47. mov r6,#0FFH
    
48. wait1:
    
49. mov r5,#0FFH
    
50. wait:
    
51. djnz r5,wait
    
52. djnz r6,wait1
    
53. djnz r7,wait2
    
54. ret
    
55. end
