| Abstract: | 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. |
