LCD12864

1> 项目概述

51单片机驱动LCD12864，显示文字和图片；

2.1> LCD硬件原理框图

21

SBN0064G只支持64列，所以LCD12864需要2个；

2.2> 工作原理

2.1
主控制器-51单片机干啥活？

主控制器51单片机，模拟6800接口时序，对SBN0064G的寄存器，进行读写操作，从而传输指令和数据；

列地址控制器-SBN0064G干啥活？

SBN0064G将51单片机的数据转换为驱动信号驱动点阵屏；

12864点阵液晶屏： 128列 X 64行个像素组成，可以理解为1个像素就是1个LED；
128X64 = 8192个LED灯，想想如何驱动？
芯片SBN0064G提供了6800接口；

24

工作原理：
通过6800接口，给驱动芯片页地址（0-7），列地址（0-63）,
显示数据，实现显示控制；

例如：页地址为7，列地址为0，数据为00101101，则显示如上图蓝色部分；

2.2> 6800接口引脚功能

22

片选信号，高有效，手册有误；

数据/指令选择信号， SBN0064G更合理， RS这名让人误解；

2.3> LCD12864指令表

24
00

2.4> 6800接口时序

2.4.1> 写时序

23

R/W拉低选择写模式
使能信号E高电平期间，将数据D0~D7写入LCD控制器（SBN0064）；

2.4.2> 读时序

24

R/W拉高选择读模式
使能信号E 上升沿后，LCD控制器将数据D0~D7输出到总线；
使能信号E 拉低后，读数据总线；

5> 复盘总结

1> 刚开始调试没有显示，发现是对比度调的太低，也就是第3引脚负压输出太低，
电位器调大就可以了；
2》 最后4个像素不能显示，联系厂家后，这款屏就是这样设计；

5.1> 写时序-高电平写入数据

51

LCD_EN 一直为高电平，一直把当前行写满；

5.2> LCD_CS1一直输出方波

P4.5/ALE引脚：
默认ALE功能，如需P4.5, 在下载程序时，用STC-ISP设置；

差点没把肺欺诈，搞了大半天，一直用万用表测试P4.5的电压，
最后发现是这个问题；

真是自己给自己挖坑；
