利用LPC2300系列ARM芯片的I^2S实现WAV文件播放

Realization of WAV Broadcast Using the I^2S Based on ARM Chipset of the LPC2300 Series

I2S(Inter-IC Sound Bus,集成电路内置音频总线)是工业领域或嵌入式系统领域常用的音频总线之一,它只处理音频数据,而其它信号如编码、控制等单独传送。使用I2S总线bus和支持该接口的编解码芯片连接,从而构建一个嵌入式音频系统。

I^2S （Inter- IC Sound Bus） is one of the general audio buses applied in various industrial systems or embedded systems. I^2S processes only audio data, while transmitting other signals like various codes and control signals. This article explains how to use the I^2S bus to connect relevant supporting code chip and decode chip, hence to construct an embedded audio system.
