Nokia 5110可谓是相~ 当~ 经典了，你可以用它来打电话、砸核桃、挡子d、锤钉子，居家防身，良心佳品~=￣ω￣=

它的屏幕因为某宝上只买八块八，八块八啊~ 物美价廉，受到广大青少年的追捧~

Nokia 5110的屏幕使用的是SPI协议，但使用我图片中的屏幕模块，除了需要连接SPI的4条信号线外，还需要另外连接一个RST（重置）和BL（背光）。

Nokia 5110屏幕模块有下列引脚:

上面的电路图太乱太难看，要理清的话，一半脑细胞都可以住进精神病院了。总之Nokia 5110的屏幕是SPI通信的，参考SPI的连接方法就对了。

上面的初始化流程中给出了一些默认值，在实际使用的过程中，因为模块的不同，这些参数可能需要重新调整才能获得理想的显示效果

我们使用Arduino的硬件SPI接口来和屏幕通信，所以我们需要使用Arduino内建的SPI库

我用过诺基亚5110显示屏，不会存在复位有时不显示，有时显示。出现你这个的情况很可能是因为复位质量太差，比如复位电压不高或者复位时电压毛刺太多，你可以试着复位时按键按下的时间长一些，看有无改善。
