程序：求大佬幫忙看一下這個程序，開頭和結尾一直報錯
這個是設計做頻率計的，要求頻率，周期和脈寬，這個程序寫了測占空比的，如果不測占空比又該怎么改呢？謝謝大家啦！


單片機源程序如下:
  1. uchar keyscan(void)
  2. {
  3. char scan, tmp;
  4. p1=0xf0;
  5. if((p1&0xf0)!=0xf0)
  6. {delay(10);
  7. if((p1&0xf0)!=0xf0)
  8. {scan=0xfe;
  9. while((scan&0x10)!=0)
  10. {
  11. p1=scan;
  12. if((p1&0xf0)!=0xf0)
  13. {tmp=(p1&0xf0)|0xf0;
  14. while((p1&0xf0)!=0xf0);
  15. return((~scan)|(~tmp));}
  16. else scan=(scan<<1)|0x01;
  17. }
  18. }
  19. }
  20. return(0);
  21. }
  22. void keychuli()
  23. {

writedata 和writecommand應該在頭文件里面吧？
