关于SPCE-61A录音笔的设计

摘要近几年来,“后PC时代”的提法不时见诸报端。所谓“后PC时代”puting,译为渗透到各个方面的计算。单片机作为计算机技术的一个重要组成部分、嵌入式系统的排头兵,随着微电子技术的迅速发展,单片机的功能也越来越强,各种应用系统开发研制更是离不开单片机应用技术,作为嵌入式系统主要部件的单片机已经成为一个重要的研究领域。本文主要通过系统介绍SPCE061A型16位单片机的原理与应用,重在介绍了凌阳单片机的集成开发环境。接着进行了系统的硬件设计,包括音频输入输出电路的设计、按键控制电路的设计等,然后分模块进行了软件设计,包括主程序模块、语音信号采集模块、键盘模块设计等,进行了程序流程的设计,编写了程序代码,最后使用IDE进行了仿真调试,验证了系统设计的正确性。系统实现了语音数据的录制、播放、暂停等功能,设计具有一定的应用价值。

ABSTRACT
In recent years, "hind PC times" was frequently appear in so-called "hind PC times" that puting, translated as puter as puter technology is an important part of the embedded system, the vanguard, with the rapid development of microelectronic technology, SCM function also more and more strong, various application systems development is inseparable from the SCM application technology, as an embedded system ponents of SCM has e an important research article mainly through the system of type SPCE061A 16 bit single chip puter principle and application is introduced, Ling Yang monolithic integrated development the hardware design of the system, including an audio input and output circuit, storage cir
Then we have a modular software design, consisting of the module of the main program, the acquisition module, key scanning module and memory module for the voice signal. Meanwhile, we plish the design of the program flow and write the source code of the design, control circuit design, liquid crystal display circuit design, Finally using the IDE undertook emulation debugging, the system design is system realized the voice data recording, playback, pause and other functions, the design has a certain value.
Keyword: Single-Chip puter, Record play, circuit design, software realization
第1章凌阳单片机开发环境及其特点

随着科技日新月异,家电产品的种类越来越丰富,越来越多微小型产品充斥市场,其特点在于体积轻巧、便于携带。录音笔作为一种方便获取和记录声音的工具具有广大的市场前景。
数码录音笔,实际上是一种采用数码录音技术的录制设备,通过对声音进行采集、压缩、存储到闪存(Flash Memory)进行记录,无需使用额外的录音磁带、话筒等设备,音质清晰逼真,
