LCD12864显示实时时钟例程可运行

DS1302是美国DALLAS公司推出的一种高性能、低功耗的实时时钟芯片，附加31字节静态RAM，采用SPI三线接口与CPU进行同步通信，并可采用突发方式一次传送多个字节的时钟信号和RAM数据。

实时时钟可提供秒、分、时、日、星期、月和年，一个月小与31天时可以自动调整，且具有闰年补偿功能。

如图1-1，液晶正常情况下，其分子排列很有秩序，显得清澈透明，一旦加上直流电场后，分子的排列被打乱，一部分液晶变的不透明，颜色加深因而能显示数字和图像。

管脚一共1个CS1左半屏片选端，CS2右半屏片选端；V0液晶显示驱动电压，通过一个电位器接到VCC；RS数据指令选择信号，H为数据，L为指令，也叫D/I；R/W读写选择信号，H为读，L为写，。

E为LCD使能端，R/W为L时，E信号下降沿锁存DB7-DB0；R/W为H时，E为H，DDRAM数据读到DB7-DB0。

DB0-DB7数据传输端口。

RST复位信号。

-VOUT和V0为液晶显示驱动电压。

12864是一种图形点阵液晶显示器,它主要由行驱动器/列驱动器及128×64全点阵液晶显示器组成。

可完成图形显示，也可以显示8×4个(16×16点阵)汉字。

图1-1 12864LCD液晶显示屏二、方案设计实物硬件设计单片机控制液晶显示屏系统总共可分为六个环节，分别是单片机控制系统、12864字符显示模块、控制开关模块、晶振控制模块、复位电路模块和DS1302时钟控制模块。

通过这六个模块的协调工作就可以完成相应的液晶屏控制和显示功能。

这六个模块的相互连接如图2-1:图2-1 硬件组成框图系统硬件设计本硬件电路主要由四大模块组成：主芯片模块；晶振和复位电路模块；控制接钮模块；显示电路模块。

51单片机LCD12864绘图

LCD12864绘图方法如下：一、绘图方法：1、使用扩展指令集并关闭绘图显示2、输入y轴坐标3、输入x轴坐标4、写入数据D15-D85、写入数据D7-D06、开绘图显示7、返回普通指令对应程序如下：LCD_write_comm(0x34);//使用扩充指令集LCD_delay();LCD_write_comm(0x80+y);//y坐标起始地址LCD_delay();LCD_write_comm(0x80+x);//x坐标起始地址LCD_delay();LCD_write_date(0x55);//写入数据D15-D8LCD_delay();LCD_write_date(0x55);//写入数据D7-D0LCD_delay();LCD_write_comm(0x36);//显示RAMLCD_delay();LCD_write_comm(0x30);//退出扩展指令集LCD_delay();程序执行效果则是第一行的第1-16个像素点会描出0x5555的二进制像素点，则后面的整个屏幕则是花屏，如果只想看到这0x5555,这几个像素点，则必须要给LCD的RAM重新赋值，也可以说是清屏，程序如下：void LCD12864_RAM_Cls(){u8 x,y;//xy坐标LCD_write_comm(0x34);//使用扩充指令集LCD_delay();for(y=0;y<32;y++){LCD_write_comm(0x80+y);//y坐标起始地址LCD_delay();LCD_write_comm(0x80);//x坐标起始地址LCD_delay();for(x=0;x<16;x++){LCD_write_date(0x00);LCD_delay();LCD_write_date(0x00);LCD_delay();}}LCD_write_comm(0x36);//显示RAMLCD_delay();LCD_write_comm(0x30);//退出扩展指令集LCD_delay();}二、坐标与显示X轴坐标设定初始值后会自动加1，取值范围0-15Y轴需要人为加1，取值范围为0-31整个屏幕分为上下屏，上屏对应坐标为x(0-7)y(0-31),下屏对应坐标为x(8-15)y(0-31)三、LCD12864图片显示代码1、Main.c#include"common.h"#include"delay.h"#include"12864.h"unsigned

2.3.2 时钟电路模块的设计 DS1302 是一种高性能、低功耗、带RAM的实时时钟电路，它可以对年、月、日、周日、
时、分、秒进行计时，具有闰年补偿功能，工作电压为2.5V～5.5V。采用三线接口与CPU进行同步通信，并可采用突发方式一次传送多个字节的时钟信号或RAM数据。DS1302内部有一个31×8的用于临时性存放数据的RAM寄存器。DS1302是DS1202的升级产品，与DS1202兼容，但增加了主电源/后背电源双电源引脚，同时提供了对后背电源进行涓细电流充电的能力。
