一、显示屏模块选型 1.1 Nokia 5110 LCD（蓝屏） 液晶屏模块 1.2 简介： Nokia5110液晶是诺基亚手机的二手拆机屏，底板为本站设计，四角有定位孔，排列如下：

接线端口功能端口名称连接引脚复位RSTPB 15片选芯片使能CEPB 14模式选择： 1 写数据，0 写指令DCPB 13串行数据线DINPB 12串行时钟线CLKPB 1电源输入VCC3.3v和5v均可，经过实验验证，没有问题。最好和引脚电压一样背光控制端BLPB 0地线GNDGND

1.3 显示屏 显示分成 5 行

二、程序开发 这里有两个，关于 显示 数据的 数组，我把放在两个不同的 头文件 中，一个为了方便显示英文，一个为了方便显示中文。英文操作简单一点。 2.1 main函数
