这是以太网芯片W5500的UDP最新例程代码，基于Keil4.72版本，主控芯片为STM32F103RCT6。用户下载并烧录入MCU中Reset后，在PC上用网络调试助手虚拟一个UDP Sever/Client，W5500可以作为UDP Client/Server同PC进行数据通信测试，需注意服务器和客户端的IP及端口设置。W5500是一款全硬件TCP/IP协议栈以太网芯片，代码简单，移植到其他单片机平台非常方便。

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.

这是关于NEC公司产的SH2系列芯片的几个例子程序,对这几个熟了,就很有利于基于其上的开发的展开-This is on the NEC Corporation of the SH2 family of chip production a few examples of procedures, a few cooked this, it is very conducive to the development on the basis of their unfolding
