摘要
随着多媒体的发展,音乐播放器作为消费类电子产品,其技术在不断增长。近几年来语音识别技术迅速发展,专门用于语音识别的芯片层出不穷。结合语音识别技术与当前盛行的嵌入式技术,设计一款不仅具有传统的按键控制功能且能控制语音的音乐播放器。
虽然语音识别技术迅速发展,语音识别产品越来越广泛,但是其具有不稳定性,较容易受环境等因素的影响,还不能完全代替传统的按键控制方式。按键输入在单片机的控制中必不可少,它是单片机系统中最常用的输入设备。
本文设计了一种采用按键控制的音乐播放器。在文中首先介绍了有关单片机基础知识的一些内容,接着详细介绍了凌阳61板SPCE061A芯片的结构、性能、接口及其最小系统等相关内容。最后重点介绍了一些常用于单片机系统中的键盘和61板自带按键及其如何使用这些键盘实现音乐的播放、暂停、上一首、下一首等基本功能。
关键词:音乐播放器 SPCE061A 单片机按键控制
Abstract
Along with the development of multimedia,music player as a consumer electronic product, technology in constant growth. In recent years the speech recognition technology rapid development, specially used for the speech recognition chips emerge in endlessly. Combining with the current popular speech recognition technology and embedded technology ,design a style not only has the traditional button control function and can control the music player speech.
Although the speech recognition technology rapid development, speech recognition is more and more extensive, but its products is instability, more vulnerable to environmental factors, still pletely replace the traditional button control mode. Keystroke indispensable in single-chip puter control, it is the monly used SCM system input device.
This paper introduces a design of music player by button control. In this paper firstly introduces the basic knowledge of some relevant microcontroller, then introduces the content of sunplus SPCE061A chip 61 board structure, performance, interface and minimal systems and other related content. Finally mainly introduces some often used in the SCM system of the keyboard and 61 plate buttons and how to use these cabin music of keyboard realize the play, pause, under such a, a basic functions.
Keywords: music player SPCE061A microcontroller buttons
