摘要
以ISD4004为核心芯片的语音录放模块REC-1000在很多领域具有广泛应用,在模块的使用中不仅能完成连续单曲的录放功能,且能实现多段分时录放音效果。文章结合REC-1000模块主控芯片与微控制器的特性与工作方式,阐述了各单元电路间的数据信息传送方式,程序的下载方法,语音芯片的录放过程及信息存储方式。结果表明:合理使用REC-1000板载系统与外围电路,结合微控制器及软件控制,利用音频录放中特殊的地址存储分配方式,可实现语音文件的多形式录放。
In the core chip ISD4004 voice recording module REC- 1000 has a wide range of applications in many fields,not only in the use of the module can be completed consecutive singles playback capabilities,and can achieve multi-time-recording sound effects. This paper combining REC-1000 feature modules main chip with a microcontroller and working methods,explained data transfer method between each unit circuit,program download method,voice chip recording process and information storage. The results showed that the rational use of REC-1000 onboard systems and peripheral circuits,combining microcontrollers and software control,the use of audio recording in special address storage allocation can be realized in various forms voice file playback effect.
