通常使用的装置，用于编码和解码诸如异步比特流是一个通用异步接收器/发送器（UART），其将所提供的软件成单独比特序列的数据字节，相反，转换这样的序列比特为数据字节被传递给软件。STM32的处理器包括（最高）五个这样的装置称为USART（通用同步/异步接收器/发射器），因为它们支持超越了基本的异步通信额外的通信模式。在本章中，我们将探讨STM32 USART和（目标）之间的串行通信的USB/ UART桥接器连接到主机PC。

红外遥控器已被广泛使用在各种类型的家电产品上，它的出现给使用家器提供了很多的便利。红外遥控系统一般由红外发射装置和红外接受设备两大部分组成。红外发射装置又可由键盘电路、红外编码芯片、电源和红外发射电路组成。红外接收设备可由红外接收电路、红外解码芯片、电源和应用电路组成。通常为了使信号能更好的被传输发送端将基带二进制信号调制为脉冲串信号，通过红外发射管发射。本设计采用Atmega8作为红外发射编码和接收解码芯片。-Infrared remote control has been widely used in various types of household electrical appliances, it" s there to provide the users a lot of convenience. Infrared remote control system in general by the infrared emission devices and infrared devices to accept the composition of two major parts. Infrared emission circuit device can be by keyboard, infrared encoder chip, power and infrared emission circuit. By the infrared receiver infrared receiver circuit equipment, infrared decoder chip, power supply and application circuit. Usually better in order to signal the sending end of the transmission to binary base-band signal for pulse modulation, through the launch tube infrared emission. The design uses infrared emission Atmega8 as encoding and decoding chip receiver.
