Read-Write Mechanism of SPI Protocol-based Audio Decoder Chip VS1003 and Its Implementation Methods

介绍了一种基于SPI协议的音频解码芯片VS1003,详细介绍了VS1003芯片的读写机制,并给出了VS1003与单片机LPC2131的接口电路图,重点介绍了如何采用VS1003的SCI和SDI实现与LPC2131通信的软件流程图。

A kind of SPI protocol-based audio decode chip VS1003 has been presented in this paper. Meanwhile, it introduces the read-write mechanism of VS1003 chip in detail, gives the interface circuit of VS1003 and LPC2131, and finally concentrates on software flow chart which is to show bow to make use of SCI and SDI of VS1003 to achieve communication with the LPC2131.
