说明：  前期接手了一个有关智能小区配电综合监控的项目，主芯片是C8051F120，其中用到串口uart0和uart1,源码中包含串口初始化配置 数据发送及中断接收数据，可直接应用，网上这方面介绍的很少
(Early took over a comprehensive monitoring on smart cell distribution projects, the main chip is C8051F120, which uses serial uart0 and uart1, source code contains the configuration data to initialize the serial port to send and receive data interrupt can be directly applied, this presentation is online less)
