无字库LCD12864(无时钟芯片显示时间)
基于无字库12864液晶模块的日历钟设计制作
基于无字库12864液晶模块的日历钟设计制作时间：2010-10-18 21:07:14 来源：作者：本文我们要利用无字库12864液晶模块来自制一个小小日历钟，最图终效果图见图1。
这个小小日历钟有什么特点呢?1、电路简单，使用元件少，容易制作，核心就是单片机ATMega8L和日历钟忡1302。
2、全部使用低压元件，3V电压就可以工作。
3，使用自编的小字模和图形界面使得显示具有特色：在文字界面可以清晰地读出当前的日期和时间，而且加入一个小动画使显示更加生动，在图形界面使用模拟刻度和指针动态指示当前时间，两个界面柙按键切换。
图2电路原理4、电源制作在独立的小电路板上，调试程序时插入使用USB供电的3.3V稳压电源，完毕后可以取下，插上开关，使用电池供电。
5、不用背光时耗电很小(全机约3mA)，可以使用圆片锂电池CR2O32供电。
日历钟安装在一块50mm x50mm小万用板上。
外形见图1。
电路原理电原理图见图2，液晶型号如前述，单片机就是AVR的ATMega8L-8PU(以下简称M8)，可以在低电压下工作，M8 的PD口控制液晶，主要就是控制串行写入显示数据。
DS13O2(以下简称1302)是常用的日历时钟芯片，32768Hz晶体B是它的振荡源。
在它内部有10个命令寄存器用来存储日期、时间的数值并控制芯片工作，M8通过PB0PB1、PB2控制1302的RST、SCLK、I/O：RST为高时才能读写1302，读写都是让数据在I/O串行传送，当SCLK上升沿时写入1位地址或数据，写入1位地址或数据。
写入地址后每当SCLK 下降沿时则读出数据。
读写都是从最低位开始，受SCLK时钟同步。
接通电源后它必须通过单片机程序启动计时，只要有电源或者各用电源存在，它就能一直工作下去，和单片机是否工作无关。
连接在M8的PC口的4个轻触按键，S1，S2，S3用于调校时问：分别为确认修改、移动光标，修改数值;S4用于界面切换。

AVR事无巨细系列七,LCD12864
事无巨细，LCD12864上次写了1602的使用，这次来写写LCD12864。
作为绝大多数单片机学习板的液晶显示模块之一，LCD12864功能要比LCD1602要强悍许多。
仅仅是1602的两行英文字母，数字和各种符号，严格来说勉强能显示几个中文，是无法满足我们的需求的。
当需要显示一些稍微复杂的图形的时候，12864的用处就显现出来了。
下面是两个正在工作的LCD12864:跟1602一样，各种型号的LCD12864在价格，性能，效率上也都是大同小异。
据我所知，市场上全新的12864价格在50到80不等，感觉有点贵。
不过，如果你要买的话，最好了解清楚它是不是带字库的。
什么是字库呢？就是在12864里的CGROM 存储器里存放有可调用显示的绝大部分的中文和各种符号。
这和我们调用GCC-AVR 的各种头文件里的子函数有点类似：如果没有这个头文件，那么你只能自己去编写；同样如果12864没有字库，你也需要自己去编一个字库，只是方式上是通过图形取模软件来转换实现的。
建议对自己实力不太自信的朋友购买带字库的LCD12864。
LCD12864，即像素为128*64的显示液晶。
它的每一行横向一共有128个可显示点，每一列纵向有64个，这些“点”其实也都是一个个发光二极管。
它可以在一个16*16的点阵区域上显示一个中文；也可以在一个8*16的点阵区域显示一个非中文字符，一般称为半宽字体。
即一个中文字所占显示面积是一个非中文字符的两倍。
LCD12864其实还有个叫法叫12864图形点阵，看出关键了么？对了，点阵二字。
归根结底，它是一个点阵。
既然是点阵，那么它的工作原理就和我们以前接触的LED 点阵类似。
B b s .C e p a r k .c o m即在要点亮的“点”上赋予正向压降即可。
理解这点，对使用12864的图形显示功能有基础作用。
关于LCD12864的引脚结构和功能，并非全部的LCD12864引脚都是一样的。
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。

LCD12864（概念）
LCD12864（概念）LCD12864（控制芯片ST7920）128×64点阵液晶显示屏有三种控制器，分别是KS0107（KS0108）、T6963C和ST7920，三种控制器主要区别是：KS0107（KS0108）不带任何字库、T6963C带ASCII码，ST7920带国标二级字库（8千多个汉字）。
如果控制芯片为st7920。
带字库。
通讯方式：串行、并口可选；无需片选信号。
以下是需要了解的LCD12864液晶的概念：做液晶显示时DDRAM，CGROM，CGRAM,GDRAM的概念。
1、DDRAM是与显示屏对应的，DDRAM的容量比显示屏大很多，在做滚动屏或者翻页，页面切换时是有用的！！可以先把数据写到RAM里，一个命令切换就OK了。
2、CGROM是内部字符发生器。
存了一些预先设好的点阵。
当我们再DDRAM中输入某字符的代码时，它会自动显示其中的字符信息。
3、CGRAM用来给用户可以自定义所需的文字或符号，应该是写到RAM里就跟CGROM 一样用了。
CGRAM是用户自建字模区，有时ascii码表不能满足个人对字符的要求，则需要在这里写入字模。
字模的方式和CGRAM中的一样。
4、绘图RAM（GDRAM）绘图显示RAM 提供64×32 个位元组的记忆空间，最多可以控制256×64 点的二维绘图缓冲空间，在更改绘图RAM 时，先连续写入水平（0x80~0x87）与垂直（0x80~0x9f）的坐标值，再写入两个8 位元的资料到绘图RAM，而地址计数器（AC）会自动加一；在写入绘图RAM 的期间，绘图显示必须关闭，整个写入绘图RAM 的步骤如下：1、关闭绘图显示功能。
2、先将垂直的坐标（Y）写入绘图RAM 地址；3、再将水平的位元组坐标（X）写入绘图RAM 地址；4、将D15——D8 写入到RAM 中；5、将D7——D0 写入到RAM 中；6、打开绘图显示功能。
