基于 Android 手机的多轴飞行器姿态控制系统摘 要随着 Android 开发技术的日趋成熟，基于 Android 操作系统的手机使用也越来越广泛，从而 Android 手机的音频接口技术的进展也引起了软件开发人员的广泛关注，可以利用音频接口进行相关的控制。音频接口通常与前置麦克、线路输入和其他一系列的输入设备配合使用。 在深化理解 Android 开发技术和音频接口后，构建了一个小型控制系统。 该系统中通过Android 平台播放纯音文件，纯音文件播放使得音频接口输出正弦波信号，并通过Android 端的程序控制信号的幅度和频率。Android 端通过音频线与 ARM 开发板连接，ARM 开发板将接收的信号转换为遥控器所需的模拟信号，从而控制遥控器发出无线电波控制多轴飞行器的姿态。Android 端的音频接口输出四路信号，左、右两个声道的幅度和频率信号分别对应多轴飞行器的俯仰，横滚，偏航和油门四个姿态。该设计最终实现了将 Android 平台输出的音频信号转换为四路的数字信号，还未能在实体的多轴飞行器上进行测试。关键词 Android；音频；单片机The Multirotor Attitude Control System Based on AndroidAbstractWith the maturing of Android development technology, based on the Android operating system is becoming more and more widely used. so the Android mobile phone audio interface technology development also caused wide attention of software developers, can use to control audio interface. Audio interface and pre - mike usually, line input and a host of other input devices.In the deep understanding of the Android development technology and audio interface. I built a small control system. The system through the Android platform in the play pure tone files, pure tone file broadcast audio interface output sine wave signal, and through to the Android program control signal amplitude and frequency.Android through audio line connected to the ARM development board, ARM development board will receive signals into analog signals required for remote control, remote control to control a radio control multi-axi...
