LCD12864简介

       LCD12864液晶屏，背面3个COB牛屎堆，一个主控芯片ST7920，另外两个是移位芯片ST7921.

主控芯片ST7920的功能是：

1. 与我们的单片机并行通信。
2. 字库ROM、CGROM，DDRAM等。
3. 行扫描COM0 ~ COM31…
4. 列扫描SEG0 ~ SEG63…
5. 串行方式发送数据到两片ST7921驱动芯片。

驱动芯片ST7921的功能是：

1. 接收来自ST7920的串行信号，转化成并口驱动电压。
2. 根据信号要求，两片芯片分别驱动SEG64~ SEG159，SEG160~ SEG255

       LCD12864它本质上是256x32点的矩阵屏，32行扫描是COM0-COM31，列字节是SEG0-SEG255总共32字节，每个字节8bit，总共256位。.
       原本左右拼接的256x32点，变成了上下拼接的128x64点。如下图所示：

串行通信

如图，所用SPI应为模式0，其中RW口为MOSI，E口为SCLK，RS口为CS，PSB应接地。

示例程序

VSS		——	GND
VDD		——	VCC(5V or 3.3V)
V0			亮度调节 
CS(RS)	——	接VCC，持续高电平，一直选通。
MOSI(R/W)——	接MOSI
SCLK(E)	——	接SCLK
PSB		——	接GND  串行模式
BLA		——	VCC(5V or 3.3V)
BLK		——	接GND			
剩余引脚不接，留空
