摘要
详细分析了DSP SPI接口的工作原理,着重介绍了SPI的软硬件设计方法,首次明确提出DSP之间通信的数据报文规范,并应用这种报文规范实现了DSP之间点对点通信。实验证明,这种方法简单方便、运行可靠。
This article analyzes characteristics and theory of SPI in detail, and addresses hardware and software design issues of SPI interface. A message specification is presented that supports the communications between DSPs. It is used to implement the point-to-point communication between two DSPs. The method verified by experiments is simple and reliable.
