基于SPI串行总线的语音接口电路的软硬件设计

Software and Hardware Design of Voice Interface Circuit Based on SPI Serial Bus

使用SPI串行总线可以达到MCU与语音芯片串行通信的目的。通过对PIC单片机与ISD4003的连接电路和软件控制的设计,实现现场语音分段录放及随即组合放音。

With SPI serial bus to carry out the serial correspondence between MCU and voice chip. Realizing the locale voice to be recorded and played one section by one section and to be made up together and played immediately by designing the interface circuit and software control.
