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

LCD12864(不带字库)

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。

(1)点阵式液晶模块LCD的显示原理 点阵式液晶模块LCD的显示原理 LCD
点阵式液晶模块LCD,可以显示字符、数字,还可以显示各种图 形、曲线及汉字,其原理是控制LCD点阵中的点的亮暗,亮和暗的点 阵按一定规律可以组成汉字,组成一幅图形和曲线等。 对用户来说,LCD屏幕上的点阵是按字节方式8个点一组来控制的。 例如:一个16点阵的汉字在LCD上显示是采用16×16个点来表达的, 即一个16点阵的汉字需要32个字节的编码数据,这些数据包含了 16×16点阵中亮和暗的控制信息。这些包含亮和暗控制信息的16×16 点阵,就是字模。

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。
