智能电子钟LCD显示，有图，求程序智能电子钟LCD显示，有图，求汇编程序，各位大虾帮帮忙！1.设计要求以AT89C51单片机为核心，制作一个LCD显示的智能电子钟：(1)计时：秒、分、时、天、周、月、年。(2)闰年自动判别。(3)五路定时输出，可任意关断（最大可到16路）。(4)时间、月、日交替显示。(5)自定任意时刻自动开/关屏。(6)计时精度：误差1秒/月（具有微调设置）。(7)键盘采用动态扫描方式查询。所有的查询、设置功能均由功能键K1、K2完成。以前的程序#include#define uchar unsigned char#define uint unsigned intuchar code table=0123456789;sbit lcd_rs=P25;sbit lcd_rw=P26;sbit lcd_en=P27; /液晶位定义sbit Sclk=P16;sbit Io=P35;sbit Rst=P17; /DS1302位定义void init();uchar ds_read(uchar com);void ds_write(uchar com,uchar value);void lcd_write_com(uchar com);void lcd_write_date(uchar h,uchar w,uchar date);void delay(uchar z);void main() init(); while(1) lcd_write_date(0,0,2); lcd_write_date(0,1,0); lcd_write_date(0,2,tableds_read(0x8d)/10); lcd_write_date(0,3,tableds_read(0x8d)%10); lcd_write_date(0,4,-); lcd_write_date(0,5,tableds_read(0x89)/10); lcd_write_date(0,6,tableds_read(0x89)%10); lcd_write_date(0,7,-); lcd_write_date(0,8,tableds_read(0x87)/10); lcd_write_date(0,9,tableds_read(0x87)%10); lcd_write_date(0,11,D); lcd_write_date(0,12,a); lcd_write_date(0,13,y); lcd_write_date(0,14,:); lcd_write_date(0,15,tableds_read(0x8b); /lcd_write_date(1,0,c); /lcd_write_date(1,1,u); /lcd_write_date(1,2,i); lcd_write_date(1,0,X); lcd_write_date(1,1,i); lcd_write_date(1,2,a); lcd_write_date(1,3,o); lcd_write_date(1,4,D); lcd_write_date(1,5,o); lcd_write_date(1,6,n); lcd_write_date(1,7,g); lcd_write_date(1,8,tableds_read(0x85)/10); lcd_write_date(1,9,tableds_read(0x85)%10); lcd_write_date(1,10,-); lcd_write_date(1,11,tableds_read(0x83)/10); lcd_write_date(1,12,tableds_read(0x83)%10); lcd_write_date(1,13,-); lcd_write_date(1,14,tableds_read(0x81)/10); lcd_write_date(1,15,tableds_read(0x81)%10); /*液晶写命令操作*void lcd_write_com(uchar com) lcd_rs=0; lcd_rw=0; lcd_en=0; P0=com; delay(5); lcd_en=1; delay(5); lcd_en=0;/*液晶写数据操作*void lcd_write_date(uchar h,uchar w,uchar date) lcd_write_com(0x80+0x40*h+w); lcd_rs=1; lcd_rw=0; lcd_en=0; P0=date; delay(5); lcd_en=1; delay(5); lcd_en=0;/*初始化*void init() lcd_write_com(0x38);/液晶初始化 lcd_write_com(0x0c); lcd_write_com(0x06); lcd_write_com(0x01); ds_write(0x8e,0x00);/打开写保护 ds_write(0x84,0x00);/选择24时计时 ds_write(0x8c,0x10);/写入10年 ds_write(0x88,0x10);/写入10月 ds_write(0x86,0x28);/写入27日 ds_write(0x8a,0x04);/写入星期3 ds_write(0x84,0x15);/写入15时 ds_write(0x82,0x15);/写入15分 ds_write(0x80,0x00);/写入0秒 ds_write(0x8e,0x80);/关闭写保护/*延时操作*void delay(uchar z) uchar a,b; for(a=z;a0;a-) for(b=110;b0;b-);/*DS1302读操作*uchar ds_read(uchar com) uchar i=0,value=0; Rst=0; Sclk=0; Rst=1; for(i=0;i=1; for(i=0;i8;i+) Sclk=1; Sclk=0; if(Io) value|=0x01i; Rst=0; value=(value/16*10)+v
