Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S

基于STM32F107开发板，移植ucos-II（V2.86）操作系统+LWIP（V1.31），实现基本的网络功能。 不同的开发板需要根据网卡芯片的物理连接做适当修改，本例用的是DP83848网卡芯片。 lwip提供raw和BSD两种socket接口，方便用户在此基础上进程网络应用程序的开发。 raw编程可以参考lwip编程指南1.0，BSD与其他平台上的网络编程具有很强的可移植性。
