标题: da.h头文件下载
msp430单片机da.h头文件代码最后的复制代码保存到电脑的方式实现下载：

1. void da12(void)
   
2. {DAC12_0DAT =166*a*2;
   
3. if(a==0)DAC12_0DAT=0;
   
4. }
   
5. void da12chuli(void)
   
6. {//uint dianliu1;
   
7. //dianliu1=(()/4096);long)(DAC12_0DAT*250
   
8. //if(dianliu1>(dianliu[a]*2))
   
9. //DAC12_0DAT--;
   
10. //if(dianliu1<(dianliu[a]*2))
