一.首先这套题目难度还可以，不是那么的简单，我也做了好一会，主要是不会操作蜂鸣器！
下面就直接贴代码了。想要工程文件的可以到博主的资源中下载（免费）点点关注就行！
主函数main.c
1. #include "dmx.h" 2. #include "onewire.h" 3. void main() 4. { 5. 6. Init_System(); 7. 8. 9. while(1) 10. { 11. if(flag_t) 12. { 13. temp=Read_temp(); 14. flag_t=0; 15. } 16. 17. scan_kbd(); //扫描按键 18. key_real(); //按键操作 19. Read_time(); //读时间 20. SMG_show(); //赋值显示 21. led_work(); //led和继电器 22. 23. 24. } 25. 26. 27. }
二. 然后就是配置文件了 也是程序核心
