基于51单片机的万年历小项目，内容比较简单就不给大伙丢人细讲了。程序和仿真包含在附件中
仿真原理图如下（proteus仿真工程文件可到本帖附件中下载）
单片机源程序如下:
- #include <absacc.h>
- #include <intrins.h>
- #include <reg51.h>
- #include "HZcode.h"
- #include "LCD.h"
- #include "1302.h"
- #include "key.h"
- #include "adc0831.h"
- uchar time0_count; //time0计数器
- //time0初始化
- void time0_init(void)
- {
- EA = 1;
- ET0 = 1;
- TMOD = 0x01;
- PT0 = 1;
- TH0 = 0x3C;
- TL0 = 0xB0;
- TR0 = 1;
- }
- void main(void)
- {
-
- I_init();
- InitLCD();
- time0_init();
- show_hz();
- show_date_time();
- while(1)
- {
- judge_key();
- }
-
- }
- void time0_interrupt(void)interrupt 1
- {
- TH0 = 0x3c;
- TL0 = 0xb0;
- time0_count++;
- if(time0_count==20)
- {
- time0_count=0;
- show_date_time();
- a = readadc();
- b1 = a/100;
- b2 = (a%100)/10;
- b3 = (a%100)%10;
- r_show_ad();
- P3 = a; //进行数模转换
- }
- }
