这个是一个远程监控系统，包括上位机和单片机程序。通过这个程序可以熟悉通信的写法和协议的定义。-This is a remote monitoring system, including PC and microcontroller program. This program can communicate through the familiar definition of the wording and agreements.

单片机UDP协议源码，用C8051F040单片机与CP2200网络芯片实现以太网通信。-tcp/ip source code on c8051f120 plus cp2200 chip.-SCM UDP protocol source code, C8051F040 microcontroller with CP2200 network chip Ethernet communication.-tcp/ip source code on c8051f120 plus cp2200 chip.

TCP通信 协议，跟单片机交互。十六进制和二进制都能收发。(TCP communication protocol, with the single chip computer interaction.)

利用rtl8019as实现单片机以太网的连接，主要对TCP/IP协议进行简化。(Using rtl8019as to realize the Ethernet connection of MCU, the TCP/IP protocol is simplified.)
