标题: 使用STC15单片机驱动的OLED DS1302时钟
以前搞的一个项目，现在拿出来分享一下代码（实物很久以前就损坏了）

单片机源程序如下:
  1. #include<stc15f2k60s2.h>
  2. #include<LQ12864.h>
  3. #include<ds1302.h>
  4. #include<ds18b20.h>
  5. sbit SetMode=P5^4;
  6. sbit SetTimes=P5^5;

  8. void delayk(unsigned int MS)   //误差 0us
  9. {
  10.         while(MS--)
  11.         {
  12.     unsigned char a,b;
  13.     for(b=129;b>0;b--)
  14.         for(a=45;a>0;a--);
  15. }
  16. }
