旨在介绍一种方法:在C54x系列DSP平台上通过设置McBSP为GPIO,然后通过模拟I2C接口的时序实现对语音编解码器TLV320AIC23的配置,通过这种方法可以有效解决C54x系列DSP没有专用I2C口,与其他I2C设备对接困难的问题。介绍了实现该方法的硬件设计和如何在软件上具体实现该方法。
The purpose of this paper is to introduce a method to realize the configuration of speech codec TLV320AIC23 by setting McBSP as GPIO on the C54x series DSP platform and then simulating the timing of I2C interface so as to effectively solve the problem that C54x series DSPs do not have a dedicated I2C port , Difficult to interface with other I2C devices. Describes the hardware design of the method and how to implement the method in software.
