lwipopts.h文件存放一些宏定义,用于剪切LwIP功能,该文件拷贝自ST官方带操作系统的工程文件,方便我们移植,该文件同时使能了Netconn和Socket编程支持。这里我们还需要对该文件一个宏定义进行修改,直接把TCPIP_THREAD_PRIO宏定义为6,该宏定义了TCPIP任务的优先级。
open to priority inversion, so this is not recommended any more) * Added LWIP_NETCONN_SEM_PER_THREAD to use one "op_completed" semaphore per thread instead of using one per netconn (these semaphores are used even with core locking

在操作系统环境下,LwIP会作为一个线程运行,线程的名字叫tcpip_thread,在初始化LwIP的时候,内核就会自动创建这个线程,并且在线程运行的时候阻塞在邮箱上,等待数据进行处理,这个邮箱数据的来源可能在底层网卡接收到的数据或者上层应用程序的数据,总之,tcpip_thread线程在获取到邮箱中的数据时候,就会退出阻塞态,去处理数据...

Previous versions of lwIP required the sys_arch to implement timer scheduling as well but as of lwIP 0.5 this is implemented in a higher layer. Sys_arch 需要为 LwIP 提供信号量和邮箱两种进程间的服务(通信方式).如果想获得完整的 LwIP 功能,需要在 sys_arch 中实现多线程的支持,但对于基本的 LwIP...
