VS1003芯片的音乐片选程序，此芯片的初始化和使用

这是一个UCOSIII移植到STM32F2XX上的例子，内部有详尽的注释。这也是本人工作这么久，辛苦总结的。uC/OS-III(Micro C OS Three 微型的C 语言编写的操作系统第3版)是一个可升级的，可固化的，基于优先级的实时内核。它对任务的个数无限制。uC/OS-III 是一个第3 代的系统内核，支持现代的实时内核所期待的大部分功能。例如资源管理，同步，任务间的通信等等。然而，uC/OS-III 提供的特色功能在其它的实时内核中是找不到的，比如说完备的运行时间测量性能，直接地发送信号或者消息到任务，任务可以同时等待多个内核对象等

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
