原来是用4位LED显示的时钟修改的热敏电阻温度计
修改成通电就显示温度计 4位LED显示正常， 修改去除. ds1302.c和ds1302.h . 热敏电阻温度显示带有鬼影 把 原来的程序 和修改的程序 放上给大家看看是那里出问题 那位师博能 看 修改后的程序那里出问题的,修改上传一下谢谢
单片机源程序如下:
- #include <reg51.h>
- #include <math.h>
- #include "ADC.H"

- sbit LED3 = P3 ^ 5;//数码管3
- sbit LED4 = P3 ^ 4;//数码管4
- //为了编程方便定义的位变量
- sbit a0 = ACC ^ 0;
- sbit a1 = ACC ^ 1;
- sbit a2 = ACC ^ 2;
- sbit a3 = ACC ^ 3;
