录音笔的设计(毕业论文)
湖南工业大学本科毕业设计(论文)
摘要
本次课程设计的主要目的是制作一个基于单片机的数码录音和播放系统。选用凌阳16位单片机SPCE061A和外部存储器W29C040来实现。其具有体积小、集成度高、功耗低、结构简单、中断处理能力强等特点,特别适用于数字语音录放和语音识别等数字应用领域。SPCE061A是台湾凌阳公司生产的十六位单片机,该单片机内置有2路DA转换,8路AD转换及在线仿真等丰富的功能,W29C040是台湾华邦公司生产的4M位的FLASH存储芯片,利用它存储凌阳格式的语音资源,可以长达4分钟的语音录放。该系统可以广泛应用于需求的录音较长的场合。如检测温度的存储播放系统,自录语音提示等应用方案。

ABSTRACT
This course design of the main purpose is to make a based on SCM digital recording and playback system. Choose Sunplus SPCE061A and 16-bit single chip external memory W29C040 to achieve. Its integration with small size, high, low power consumption, simple structure, interrupt handling ability strong wait for a characteristic, especially suitable for digital voice recording
and digital applications speech recognition, etc. Sunplus SPCE061A is pany produces the 16 microcontroller, the microcontroller built-in have 2 DA conversion, AD transform and online simulation and so on the function,W29C040 is of Taiwan Winbond corp. Production 4M bits FLASH memory chips, and use it to store the voice of Sunplus format for four minutes resource can the voice recording. This system can be widely used in demand recording longer occasion. If the test temperature broadcast system, self-records stored voice prompt etc application solutions.
