12864时钟显示程序/*用LCD12864液晶显示器进行设置时钟，有独立键盘调节时间程序*/个人觉得在学习编写LCD12864显示程序时可以多结合1602一起来学习，很多东西是相通的，我这个程序就是，还有对于初学者来说，最好是理解程序每个模块的作用，掌握后对于以后的编程学习进度会更快，再补充说明一句，对于显示模块程序，着重需要对地址些函数部分理解，废话不多说，看程序吧：#include#define uchar unsigned char#define uint unsigned intsbit RS= P2^6;//数据/命令选择端(H/L)sbit RW= P2^5;//读写/选择端(H/L)sbit EP= P2^7;//使能信号sbit K1=P3^0; //开关定义sbit K2=P3^1;sbit K3=P3^2;uchar num,t;uchar K1num;char s,f,m; //可取负数uchar code table[]= " 2013-8-12 MON ";//日期显示uchar code table1[]=" 00: 00: 00 AM "; //时间显示uchar code table2[]="长沙今日多云"; //天气显示uchar code table3[]=" 南风39-30℃"; //气温显示void init1(); //中断子函数void delay(uint k) //延时函数{uint i,j;for(i=k;i>0;i--)for(j=110;j>0;j--);}void write(uchar com) //命令指令函数{ //根据时序图来设置RS=0; //选择指令寄存器RW=0; //选择写P0=com; //将8位数据通过P0口传给12864delay(5); //延时一会，让12864准备接收数据EP=1; //使能线电平变化，数据送入1602的八位数据口delay(5);EP=0;}void read(uchar date) //写入指令函数{ //根据时序图来设置RS=1; //选择寄存器RW=0; //选择写P0=date; //将8位数据通过P0口传给12864delay(5);EP=1;delay(5);EP=0;}void init() //初始化函数{RS=0;EP=0;RW=0;write(0x38); //显示设置模式write(0x0c); //显示开关控制write(0x06); //光标设置write(0x01); //清屏设置write(0x80); //数据地址初始位for(num=0;num<16;num++) //查table表数据{read(table[num]); //读取表中内容delay(20);}write(0x90);//重新设置数据指针for(num=0;num<16;num++) //查table2表数据{read(table2[num]); //读取表中内容delay(20);}write(0x98);//重新设置数据指针for(num=0;num<16;num++) //查table3表数据{read(table3[num]); //读取表中内容delay(20);}write(0x88);//重新设置数据指针for(num=0;num<16;num++){read(table1[num]); //读取table1表中内容delay(20);}}void write_sfm(uchar add,uchar date) // 时分秒函数设置{ uchar shi ,ge;shi=date/10; // 取商ge=date%10; //取余write(0x83+add); //设置add位地置read(0x30+shi); //设置十位地置read(0x30+ge); //设置个位地址}void key() //独立开关控制{if(K1==0){delay(5);if(K1==0){K1num++;while(!K1); //判断按键是否按下if(K1num==1) //按一下调节秒{TR0=0; //关定时器write(0x83+10); //找到秒位置write(0x0f); //光标闪烁}}if(K1num==2){write(0x83+8);//再按一下调节分地址}if(K1num==3) //第三次按下调节时{write(0x83+6);}if(K1num==4) //按四次回到正常计时{K1num=0;write(0x0c);//光标不闪TR0=1;}}if(K1num!=0) //有按下{if(K2==0) //K2开关控制时分秒加{delay(5);if(K2==0) //消抖{while(!K2);//松手if(K1num==1) //秒调节{m++;if(m==60)m=0;write_sfm(10,m);write(0x83+10);//秒钟地址}if(K1num==2) //分钟调节{f++;if(f==60)f=0;write_sfm(8,f);write(0x83+8); //分钟地址}if(K1num==3) //小时调节{s++;if(s==23)s=0;write_sfm(6,s);write(0x83+6);//时地址}}}if(K3==0){delay(5);if(K3==0){while(!K3);if(K1num==1) //K3控制时分秒减{m--;if(m==-1)m=59;write_sfm(10,m);write(0x83+10);}if(K1num==2)f--;if(f==-1)f=59;write_sfm(8,f);write(0x83+8);}if(K1num==3){s--;if(s==-1)m=23;write_sfm(6,s);write(0x83+6);}}}}}void main() //主函数{init(); //调用子函数init1(); //调用定时子函数while(1){key();}}void init1() //定时子函数{TMOD=0x01;EA=1; //开总中断ET0=1; //开定时器中断TR0=1;TH0=(65536-50000)/256; //设置时间50ms TL0=(65536-50000)%256;}void e() interrupt 1 //定时器T0方式1中断{ TH0=(65536-50000)/256;TL0=(65536-50000)%256;t++;if(t==18) //一秒钟定时{m++;if(m==60) //秒设置{m=0;f++;if(f==60) //分设置{f=0;s++;if(s==24) //小时设置{s=0;}write_sfm(6,s); //时位数据读取}write_sfm(8,f); //分位数据读取}write_sfm(10,m); //秒位数据读取}}。
