菜鸟学习51单片机之12864液晶(无字库)

现在将如何在液晶上面显示字。一．清屏
/* 选择屏幕来清屏 */
菜鸟学习 51 单片机
while（1）世界
void Lcd12864Clear(uint8 selet)
{
uint8 i,j;
Lcd12864SeletScreen(selet); //选择屏，分左屏和又屏，这个函数在程序中有
for(i = 0;i < 8 ;i++)
二．写入地址
void Lcd12864Point(uint8 page,uint8 x,uint8 y)
{
Lcd12864Write(CMD,0xb8 + page);
//确定页
Lcd12864Write(CMD,0xC0 + x);
//设定起始行
Lcd12864Write(CMD,0x40 + y);

现在开始讲解如何使用，看这篇讲解前，请先到网盘去下载本教程的仿真图和程序，结合起来更容易明白。
上图是仿真的结果。在仿真软件中找出的 12864 液晶是没有字库的，对于仿真软件中液晶的控制和平常的有点不同。一块液晶是由两块 64×64 的液晶显示模块组合而成。下面是各管脚的介绍。
//有 8 页，循环 8 次
{
Lcd12864Point(i,0,0); //这个就是上面讲到的函数，确定位置
for(j = 0 ;j < 64;j++) //每一块液晶显示模块有 64 列
{
Lcd12864Write(DAT,0x00); //写入 0x00 来清屏
}
}
}
具体的使用如下：初始化函数中调用了清全屏 Lcd12864Clear(3); //清全屏

使用无字库12864液晶模块制作温湿度计

使用无字库12864液晶模块制作温湿度计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，这比看燕子飞高飞低要靠谱些吧？两个界面用按键切换；4.具备锂电池线性充电电路，通过USB接口从外部取得5V电源，一边供给充电，一边维持电路继续工作；全部元器件安装在一块70mm×90mm的小万用板上，正面、背面外形见图1、图2。

正面左边那个黑色小乌龟壳就是温湿度探头。

图2 电路板背面元器件分布和连线电路原理电路见图3。

图形点阵液晶、单片机M8、时钟电路DS1302和上次小小日历钟基本相同，不再重复。

有两点稍稍不同：1.液晶的控制虽然还是通过M8的PD口，但具体接线有所改变，不再占用两根串口线PD0和PD1，目的是为今后可能和外部通信预留接口。

这好办，编程时重新定义即可；。

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。

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。

DR和DDRAM之间的数据传输是模块内部自动执行的。

3．忙标志：BFBF标志提供内部工作情况。

BF=1表示模块在内部操作，此时模块不接受外部指令和数据。

BF=0时，模块为准备状态，随时可接受外部指令和数据。

利用STATUS READ指令，可以将BF读到DB7总线，从检验模块之工作状态。

基于无字库12864液晶模块的日历钟设计制作详细介绍

基于无字库12864液晶模块的日历钟设计制作详细介绍
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、。

纵向看，8 点一列，从上至下对应bit0 到bit7，我们用1 表示“亮”，0 表示“暗”，从左至右，依次确定为0111 1100，即0x7c ；1000 0010，即0x82 ；10000010，即0x82 ；1000 0010，即0x82 ；0111 1100，即0x7c ；如果我们依次将这5 个字节写入LCD 某页连续5个地址空间，LCD 上就会显示“0”。

下面我们把数字变量在LCD 上动态显示，就是数值变了，显示跟着变。

字符显示LCD 驱动函数，实现8×n 点阵字符写入函数。
