基于Android平台智能手机的学习型红外遥控器设计

摘要

A design of a new learning remote control er based on Atmega16 MCU and Android system is proposed.The operating principle and the design of software and hardware are introduced,and the realization is described in detail.The design of control er is for NEC Infrared Transmission Protocol and realized by measuring the bandwidth of pulses.Those widths are decoded and uploaded via Bluetooth to an Android smartphone.The application on the smartphone save the codes and control the device transmit code to control household appliances.%提出一种基于Android操作系统和单片机软硬件结合的学习型红外遥控器的设计与实现。对于该设备的工作原理，相应软硬件进行介绍，就具体实现方法进行详细地描述。该学习型遥控器针对NEC红外遥控协议，测量脉冲宽度并对其进行解码，通过蓝牙上传至Android智能手机，并可由手机端应用程序存储编码和控制单片机发送红外编码来遥控家用电器。
