ISD4004 51单片机驱动程序
本设计是基于单片设计的一个能实现语音存储和回放功能的系统,利用宏晶公司生产的STC90系列单片机作为主控制器,使用具有录音和放音功能的ISD4004语音芯片,能够显示32个字符的LCD1602显示器件和能对音频进行无失真的放大的TDA2822M差分放大器设计而成的。首先我们利用STC90C516RD+单片机的优越的控制性能来控制ISD4004语音芯片,通过单片机向语音芯片发送指令来完成ISD4004芯片的录音和放功能,用LCD1602来显示单片机对ISD4004的操作状态,使用TDA2822M将ISD4004芯片输出的音频进行无失真的放大的思路来进行语音存储和回放系统设计的,用Circuit Design Suite 10.0(Multisim)软件来绘制该系统的电路,用Keil uVision5软件来编写硬件程序。电路图和程序都完成后使用万用洞洞板依据电路图来焊接实物电路,实物完成后载入芯片程序直接进行实物调试,使用实物调试更容易找出问题和系统设计的缺陷,出现问题时可以通过模块化思想轻松查找到故障原因,并进行修复故障。ISD4004芯片录音时基于多电平存储技术实现的没有传统的数字录音过程中A/D转换带来的量化噪音和变色的金属音色。该系统录取的声音播放出来后和原音的音色、音调保持一致不失真。(This design is based on the single chip design of a voice storage and playback system, using STC90 series MCU produced by Hongjing Company as the main controller, using ISD4004 voice chip with recording and playback function, can display 32 characters LCD 1602 display device and can amplify audio without distortion. TDA2822M differential amplifier is designed. Firstly, we use the superior control performance of STC90C516RD + MCU to control the ISD4004 voice chip, send instructions to the voice chip through MCU to complete the recording and playback function of ISD4004 chip, use LCD1602 to display the operation status of MCU to)
