摘　　要：串行外设接口相比一般的串行通信接口、控制器局域网,通信速率高,接线简单,适用于大量数据的通信。针对电能质量测试设备数字信号处理与进阶精简指令集机器控制板之间需要进行高速率通信的需求,通过设计实现了串行外设接口的通信。对调试过程进行了总结,可以为其它类似工程提供技术参考。Compared with the general SCI and CAN,the SPI has a higher communication rate and simple wiring,which is suitable for mass data communication.In response to the need for high-speed communication between the DSP of the power quality test equipment and the control board of ARM,the SPI communication was realized through design.The debugging process was summarized,which can provide technical reference for other similar projects.
