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

播放应用程序包括在解码和播放Speex编码的消息，已被存储到嵌入式STM32F101xx和STM32F103xx闪存。的播放应用程序主要使用两个缓冲区来存储消息解码。一旦一个缓冲区已经发挥，应用重用解码一帧。解码后的数据被使用TIM2的中断处理函数，即在8千赫率。这个应用程序是存储语音信息很少的内存需求非常有用。的用户可以记录和存储的语音信息隐藏于闪存STM32F103xx，然后回放。在演示你最多可以存储1分钟的声音到Flash记忆。为此，必须有59字节的用于数据存储的闪存通过固件的EEPROM。为了比较的目的，一个单独使用原始的PCM格式（无Speex编解码器）来存储声音1分钟需要938字节的内存空间。这意味着一个外部使用记忆，这相当于一个额外的成本。

嵌入式图形对象/触摸屏库 STM： 应用程序库 这个图书馆是固件包，其中包含一个例程、 数据结构和宏覆盖图形库的主要特点和支持 HID 设备进行交互的图形对象 （触摸屏、 操纵杆和按钮） 的集合。 图书馆是一般用途，可以在任何的 CPU 8/16/32 位，以保证最高的可移植性的任何建筑或液晶显示控制器上执行，它提供了一个图形用户界面 (GUI) 用于任何应用程序的运作与图形液晶显示器。
