基于52单片机ISD1760语音芯片的原理图和程序代码。

实现功能：在红外线上语音报警

可以录音，删除（这两个用按键即可，不用程序）；放音（放音用单片机控制）；回答合适可以加悬赏！

这个是按键录放的例程，你可以根据这个例程自己修改一下追问

算了，本来也不报太大期望，你的这个我已经有在网上找到了；硬件原理图设计我就参考isd1760基本中文资料就好了！

语音芯片ISD1760硬件连接图,求解释。答：大绿框内的：header2 是一个话筒接口，所以电阻 R1、R4、C3和R5 应该是一个偏置电路，为驻极体话筒提供偏置电流，C3 是偏置电源滤波，C4、C5 是隔直耦合电容。 C1、C10 应该属于高频旁路电容。我知道的就这么多希望能帮到你。

单片机控制ISD1760语音芯片答：按下此键后，段编号会自动加1，播放下一段语音。如果按住此键不放，段编号会自动连续加1，直到按键释放为止，当前段编号为最大时再按此键无效。主控单片机主要通过四线（SCLK，MOSI，MISO，/SS）SPI协议对ISD1760进行串行通信。ISD1760作为从机，几乎所有的操作都可以通过这个SPI协议来完成。为了兼容独...

单片机 如何让控制isd1760芯片 语音录放的 ? 录音指令与播放指令不是...答：录音指令和播放指令是不一样的。播放是0x40，录音是0x41。可以使能2脚，如果开始录音了，LED常亮。开始播放后，LED闪烁。具体操作请参考数据手册。
