此库特点除了硬件SPI，还有在RAM开了一个显存缓冲，再有查屏幕上有什么的时候就好办了
初始化重启屏幕用的PIN 6，建议只调试时候用，实际应用可做硬件重启，去掉相关段
库内有注释，还有应用问题就发帖吧 硬件SPI操作，可做硬件重启这点都差不多吧？我记得很多NOKIA 5110都是SPI控制的，沙发，顶你一个！ Randy 发表于 2012-9-26 15:36 static/image/common/back.gif

现有的5110库都未用spi.h，都是软件编程用任意io模拟spi协议的 test01 发表于 2012-9-26 16:20 static/image/common/back.gif
现有的5110库都未用spi.h，都是软件编程用任意io模拟spi协议的
是的，哈哈，是软件模拟的！ 为更方便大家应用，变更了开源许可证 有人反映说看不懂
好吧，我用中文解释下
这个库的公共函数有：
lcd5110_clear 清空显存
lcd5110_initialise 屏上电后要首先调用下这个，初始化
lcd5110_display 让屏显示出显存里的字
lcd5110_blank 让屏全屏空白，但不影响显存内容
lcd5110_sleep 让屏休眠
lcd5110_write_text 往屏上输出字串
lcd5110_write_blink_character往屏上输出闪烁的单字母
lcd5110_put_pixel 往屏上画点 :$如何制成库文件调用，还是加到程序中。 xpaul 发表于 2012-10-20 20:33 static/image/common/back.gif
如何制成库文件调用，还是加到程序中。
可以直接复制到自己的程序里
也可以按精华区那篇做库的方法做成库调用 https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library/blob/master/Adafruit_PCD8544.h lcd5110_write_text和 lcd5110_write_blink_character 函数的调用参数有改变 这代码长度。。。看来我是用不了，现在板子里空间寸土寸金的…… 'write_bit' was not declared in this scope
找不到write_bit函数
貌似

这个函数在另一个帖子里
http://www.geek-workshop.com/thread-1988-1-1.html
当然你也可以用Arduino里自带的写bit宏替换
