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。

LCD12864(不带字库)
LCD12864（不带字库）LCD12864（不带字库）其实看了本版的1602教程以后很容易就可以掌握12864了。
刚才看到有网友要12864教程，俺就把博客里以前练习的一个程序弄过来，算作参考吧。
不足之处请见谅。
这个程序浪费了我很多时间，因为我一直没有找到datasheet，12864的型号实在太多了。
为了这个程序，我在网上找了很多相关的例程，但大多都是C语言写的，可惜俺没学过C，用起来不顺手，遂将其转成汇编，但是转后，程序运行不正常，郁闷啊。
好不容易找个汇编的吧，又写得很乱，没有头绪，没有datasheet，看起来很费劲，最后终于找到一个相关的datasheet，这才完成这个程序。
总结一下：与其费力分析别人的程序，不如看datasheet自己写。
下面总结一下datasheet。
→↑← ONE→且看datasheet：12864点阵型LCD简介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。
'700')this.width='700';if(this.height>'700')this.height='700';">在使用12864LCD前先必须了解以下功能器件才能进行编程。
12864内部功能器件及相关功能如下：1. 指令寄存器(IR) IR是用于寄存指令码，与数据寄存器数据相对应。
当D/I=0时，在E信号下降沿的作用下，指令码写入IR。
2．数据寄存器(DR) DR是用于寄存数据的，与指令寄存器寄存指令相对应。
当D/I=1时，在下降沿作用下，图形显示数据写入DR，或在E信号高电平作用下由DR读到DB7∽DB0数据总线。

【0727学习笔记】LCD12864液晶显示技术-硬件介绍2008-07-27 20:18---- 根据相关资料整理，不对之处，欢迎留言或EMAIL ME niejinbo999# (#换成@) ------ 我是用Proteus仿真的，带字库的LCD12864屏近百大元一个，下载个破解版的Proteus，LCD12864屏直接拖出来就可以用了，想拖几个就拖几个，呵呵，闲话少说，进入正题。
先来看一下Proteus里面的12864长什么样，下图中就是我使用的12864屏，型号为：AMPIRE128X64管脚一共18个。
CS1左半屏片选端，CS2右半屏片选端；VCC、GND就是VCC、GND，没啥好说的；V0液晶显示驱动电压，在网上找的仿真实例中有的这个脚就悬空，我是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，有的资料上也叫D/I，我估计是DATA和INSTRUCTIONS这两个单词的缩写；R/W读写选择信号，H为读，L为写，这肯定是READ和WRITE的缩写。
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，如果只写不读的话可以接地处理。
DB0-DB7数据传输端口。
RST复位信号，不过还没弄明白是怎么回事，参考一些资料后接VCC处理。
-VOUT估计和V0差不多，液晶显示驱动电压。
PS：我在网上没找到AMPIRE128X64的资料，但其控制系统和市面上卖的有些是一样的，因此可以参考一下。
我就是参考下面这个型号的资料，需要的朋友可以留下EMIAL。
图片截自深圳彩晶科技的文档资料。
指令说明：一共有7个指令，下面分别加以说明（个人理解）显示开关 0x3e：关；0x3f：开（R/W=0，RS=0）显示起始行 0xc0+i ： i取值0至63 （R/W=0，RS=0）设置DDRAM页地址（X地址） 0xb8+i： i取值0至7 （R/W=0，RS=0）设置Y地址 0x40+i：i取值0至63 （R/W=0，RS=0）读状态 R/W为H时，暂未弄明白写数据将数据线上的数据DB7-DB0写到DDRAM ，Y地址指针自动加1 （R/W=0，RS=1）读数据将DDRAM中的数据读入1数据线DB7-DB0 ，Y地址指针自动加1 （R/W=1，RS=1）（用到的很少）DDRAM地址表(注意DB0-DB7在DDRAM里的存储空间，竖起排列）写操作时序（当E信号下降沿时写入数据）小声的说下，资料上是 L有效，时序图里怎么就H了呢？写操作时序（时序参数均为NS级，单片机为US级，故不用考虑延时）读操作时序（时序参数均为NS级，单片机为US级，故不用考虑延时）硬件介绍到此结束，有什么不对之处留言或EMAI告之。

*注释 1：如在实际应用中仅使用串口通讯模式，可将 PSB 接固定低电平，也可以将模块上的 J8 和“GND”用焊锡短接。 *注释 2：模块内部接有上电复位电路，因此在不需要经常复位的场合可将该端悬空。 *注释 3：如背光和模块共用一个电源，可以将模块上的 JA、JK 用焊锡短接。
● 字型产生 RAM(CGRAM) 字型产生 RAM 提供图象定义(造字)功能, 可以提供四组 16×16 点的自定义图象空间，使用
者可以将内部字型没有提供的图象字型自行定义到 CGRAM 中，便可和 CGROM 中的定义一样地通过 DDRAM 显示在屏幕中。
● 地址计数器 AC 地址计数器是用来贮存 DDRAM/CGRAM 之一的地址,它可由设定指令暂存器来改变，之后只要读取或是写 入 DDRAM/CGRAM 的值时，地址计数器的值就会自动加一，当 RS 为“0”时而 R/W 为“1”时，地址计数器的值会被读取到 DB6——DB0 中。

在上次介绍的日历钟的基础上扩展一下：让它具备检测大气温度和湿度的
功能，一天24 小时不间断运行并定时检测，于是，日历钟就摇身一变成为一
个小小温湿度计啦。
虽然气象要素很多，不过我们最常用的就是气温和湿度。
一个是冷热程度，一个是环境空气中含水蒸气的多少。
一般家用温度计很常见，湿度计就比较少，以前有一种干湿球温度计，但是用起来比较麻烦，准确度也不高。
现在应用电子技术我们就可以做一个可以同时显示温度、湿度、时间的小仪器，放在家里以便随时监测我们的小环境。
它的特点如下：
1.在单片机ATMega8L-8PU（以下简称M8）和日历钟电路DS1302 的基础上，使用一个在工厂经过精密校准的数字式温度、湿度传感器AM2301 作为探头；
2.当24 小时连续工作时，纵然工作电流仅为几毫安，也不宜使用纽扣电池
供电。
这次选用可充电的3.6V 聚合物锂电池，使它的放置地点可以不受电源
限制，可以在室内，也可以在不受阳光直射和雨水接触的室外；
3.具有文字和图形界面，可以显示温度和湿度数值，以及12 小时内的湿度
变化记录曲线，为什么是湿度曲线呢？因为气温的变化规律一般比较稳定，湿度就不一样了，我们可以从湿度变化趋势估计一下未来的晴雨可能，这比看燕。
