Hadoop简单应用案例，包括MapReduce、单词统计、HDFS基本操作、web日志分析、Zookeeper基本使用、Hive简单操作等(Hadoop simple application cases, including MapReduce, word counting, HDFS basic operations, web log analysis, Zookeeper basic use, Hive simple operation)

nokia 5110液晶模块的详细资料及驱动和测试程序。做电路时请不注意液晶的安全，这小东西很脆弱，不注意就会不显示或者一闪一闪的。(nokia 5110 LCD module details and drivers and test procedures. Please do not pay attention to LCD circuit safety, this little thing is very fragile, do not pay attention will not display or flicker.)

基于ARM的芯片多数为复杂的片上系统,这种复杂系统里的多数硬件模块都是可配置的,需要由软件来设置其需要的工作状态。因此在用户的应用程序之前,需要由专门的一段代码来完成对系统的初始化。(ARM-based chips, most of the complex system on chip, where the majority of this complex system can be configured hardware modules are required by the software to set up the working status of their needs. Therefore, the application before the user needs from the special section of code to complete the initialization of the system.)
