【TI首届低功耗设计大赛】让开发板说话 [复制链接]

板子回来了，这几天焊上了，今天发声了，但也有缺点就是发声的功放耗电在，用ＵＳＢ带会发出的声音不太好听，我用手机充电器的电源带，还可以． 以下是编译通过截图： 原程序如下：

2. int CS_S = 4;
3. int SCLK_S = 10;
4. int MOSI_S = 9;
5. int INT_S = 14;
6. void setup()
7. {
8. pinMode(CS_S, OUTPUT); // sets the digital pin as output
9. pinMode(SCLK_S, OUTPUT); // sets the digital pin as output
10. pinMode(MOSI_S, OUTPUT); // sets the digital pin as output
11. pinMode(INT_S, INPUT_PULLUP); // sets the digital pin as output
12. // put your setup code here, to run once:
13. digitalWrite(CS_S,HIGH);
14. digitalWrite(SCLK_S,HIGH);
15. digitalWrite(MOSI_S,HIGH);
17. }
19. void loop()
20. {
21. powerup();
22. // put your main code here, to run repeatedly:
23. while(1)
24. {
25. play(0);
26. while(digitalRead(INT_S));
27. }
28. }
30. void send8_S(unsigned char CHAR)
31. {
32. unsigned char i;
33. unsigned char temp;
34. digitalWrite(SCLK_S,LOW);
35. digitalWrite(MOSI_S,LOW);
36. for(i=0;i<8;i++)
37. {
38. digitalWrite(SCLK_S,LOW);
39. temp =CHAR & 0x01;
40. if(temp != 0)
41. digitalWrite(MOSI_S,HIGH);
42. else
43. digitalWrite(MOSI_S,LOW);
44. //delay(1);
45. digitalWrite(SCLK_S,HIGH);
46. //delay(1);
47. CHAR >>=1;
48. }
51. }
53. void powerup(void)
54. {
55. digitalWrite(CS_S,LOW);
56. send8_S(0x00);
57. send8_S(0x20);
58. digitalWrite(CS_S,HIGH);
59. }
61. void play(unsigned char m)
62. {
63. digitalWrite(CS_S,LOW);
64. send8_S(m*10);
65. send8_S(0xE0);
66. digitalWrite(CS_S,HIGH);
67. digitalWrite(CS_S,LOW);
68. send8_S(0x00);
69. send8_S(0xF0);
70. digitalWrite(SCLK_S,HIGH);
71. }

牛X，居然还用笔写程序草稿！

板，来给哥唱个小曲儿。期待更多资料。
