W5500 UDP最新版例程
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。

这是一个不到2000行的操作系统,巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间,每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1),但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样,设置MVA对应的页表指向不同物理地址就可以很方便地让各进程运行空间相互隔开。代码很少,注释丰富,希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。
-This is a trip of less than 2000 operating system, cleverly using ARM9 CPU memory management unit (MMU) to achieve the switching process. ARM9 4G virtual address can be divided into 128 process space, each 32M. While their virtual address (VA) are 0- (32M-1), but the corresponding MVA (Modified Virtual address, and by the virtual address VA and the process of portfolio from PID) not the same, set MVA corresponding page table at the different physical address can be very easy to let the the process of separating the mutual operation of space. Code rarely Notes rich, in hopes of understanding the operating system, understanding the ARM architecture friends help.
