I2S 设备和MSP430器件的连接指南

The MSP430 series of microprocessors are fast powerful devices ideally suited for use with the various wireless transceivers offered by Texas Instruments. In streaming audio applications, however, it is desirable that the microprocessor support an audio bus to allow for interconnection to an audio CODEC. This application note describes how to create an I2S-like bus (left-justified mode) from an SPI bus using a 4-bit counter, a 'D' type flip-flop, and a dual inverter gate.
