Proteus仿真 基于51单片机的 HDG12864F-1和HDG12864F-3的显示

写在前面！LCD12864和HDG12864F-x系列是不同的！

emmm现在感觉也还是不太能明白这个神奇的液晶显示模块，就是可能大概会用，找网上的模块之类的，但是对于它们是基于啥控制器？？啥指令集？？之类的还是很混乱！
一开始去完成作业的时候其实不清楚LCD12864和HDG12864F-x系列是不同的，就直接去搜了12864，搜到的结果就很混乱，我都去瞅了瞅，那感觉就是吃多了吃杂了，根本消化不了，笑死，根本理不清！一个月以后，昨天问同学（啊！好厉害噢！！）似乎？？终于？？理清楚了？笑死，我的猪脑子！

LCD12864

因为作业是基于HDG12864F-x系列完成的，我并没有去实现基于LCD12864的液晶显示仿真（似乎Proteus里面没有LCD12864？）不过在CSDN看见了写得很好！解决了我很多疑惑的！博客！！

LCD12864资料汇总

• 详解LCD12864显示屏的使用（并行控制）
  在这篇博客里面的代码，写入逻辑是——选择一个地址以后，8bit循环写进，8bit是最小单元，横着写的，然后往下竖着写满对应16行，如果是ASCII码8* 16就写好了，如果是汉字16*16，Y地址自动增加（就是横着的那个……俺混乱了！），重复一次，这样就写好了一个汉字or一个ASCII码字符；如果是字符序列，Y地址依然自动增加，就能写完所有字符；
  需要注意的是，一行最多16个ASCII字符，8个汉字字符，横坐标+1不会进位，就是写满一行以后，另一行的选择要代码更改，写入的示意图大概如下：
  

• LCD12864(带字库的)使用教程
  这篇博客的代码里，写入逻辑是——最小单位8bit横着写，写了以后继续横着写 下一个8bit，一行128bit就需要循环16次（168=128）！这样就写满一行了，12864的DDRAM有64行，再加一个外层循环写满64行，写入的示意图大概如下：
  
  上面两个代码里面的写入逻辑是不一样的，这与你取模的方式有关，或者说自己取模的时候和代码里怎么写进入要对应！！

基于51单片机 HDG12864F-3显示图片的Proteus仿真

一开始完成作业就是参考的这篇博客！proteus中 基于STC89C51的HDG12864F-3显示器仿真
但是不知道博主最后写地址的时候，y那里是不是写错liao。
我是看的这个数据手册：HDG12864F-3中文资料
HDG12864F-3是并行的，数据是8bit并行传输的，比较重要的引脚是A0、RW（组合有读写指令/数据）、E（使能）：

这里是指令集合——

关于黄色框里面的指令——主要是在写入要显示的取模矩阵时，要设置地址的一些指令：（是自己的理解，如果有不对，还望斧正）
首先要先放一张DDRAM的图：

将128*64的DDRAM分页，分成8页，一页8行，一行128bit，需要注意的是！！HDG12864的最小单元（8bit）是竖着写的！！

• Display Start Line Set：起始行设置——如上图所示，给page编号，从上往下就是0-1-2-3-4-5-6-7，但是如果设置起始行从32开始（写入指令0x60），那么页的序号就会变成4-5-6-7-0-1-2-3，就相当于从设置的那一行开始往下依次8行算一页；

• Page Address Set：页的选择——写入指令0x80+x（x即为行的序号）；

• Column Address Set Upper bit+Colunm Address Set Lower bit：列的高位+低位选择，因为一页有128列，需要7位，所以就用列的高位选择和低位选择两条指令来确定某一列（这也体现了HDG12864是竖着写的！）
  HDG12864F-3的初始化、读/写数据/指令函数、显示图片的代码如下：

参考了很多这篇博客：使用Proteus模拟操作HDG12864F-1液晶屏
数据手册：HDG12864F-1
因为HDG12864F-x系列的内部控制器是一样的，所以指令集也是一样的，写入方式当然也是一样的，就是8bit是竖着写的，感觉大概都是差不多滴！
