基于RC5编码的红外遥控器的设计
摘要
红外线遥控具有结构简单、制作方便、成本低廉、抗干扰能力强、工作可靠性高等一系列优点,是近距离遥控、特别是室内遥控的优选遥控方式。
该文介绍了基于RC5协议的红外遥控器的设计,红外遥控器由红外遥控发射电路和红外遥控接收电路组成。红外遥控发射电路使用了MSP430F2274单片机,用RC5协议将键盘采集到的信号进行编码,并通过发送电路将信号发送出去;红外遥控接收电路中有MSP430F2274单片机,一体化红外接收管,输出控制组成,一体化接收管接收发送来的红外信号,输入到单片机后采用RC5协议进行解码,最后输出控制信号。本设计在IAR Embedded Workbench开发环境中运行,采用C语言进行编程。

The Design of Infrared Remote Control Based on the RC5
Coding Abstract
Infrared remote control of infrared remote control, which is based on the RC5 protocol. Infrared remote control includes transmitter and receiver circuit. Infrared remote control transmitter uses MSP430F2274 microcontroller. The keyboard collects singal, then the controller encodes it to send infrared signals by the circuit using RC5 protocol. Infrared remote control receiver circuit includes MSP430F2274 microcontroller, the integration of the infrared receiver and output control. Integration of the receiver to receive infrared signals enters into the SCM and then decode by RC5 protocol. Finally it outputs control signals. The design operation is in
the IAR Embedded Workbench development environment, using C-language programming.
Key Words:Infrared Remote Control; MSP430 MCU; The integration infrared receiver; RC5 Protocol
