摘　　要：以同轴度测量仪最简硬件系统的设计为例,介绍了在体积受限制的应用场合下如何运用串行器件和串行接口技术,达到简化硬件、缩小体积、提高可靠性的设计目标。对SPI最基本操作的剖析,是对所有串行芯片或设备(如A/D转换器、串行液晶显示器、串口微型打印机等)进行编程的基础,有助于加深对串行接口理念的理解。Taking the design of the simplest hardware system for coaxiality measuring instrument as an example, how to use serial device and serial interface technology in the environment of re- stricted volume to realize the design goals of simplifying the hardware, reducing the volume and improving the reliability is introduced. The analysis on basic SPI operations is the basis of pro- gramming for all serial chips or devices, such as A/D converter, serial LCD display, and serial micro printer, which can help us to deepen the understanding of the serial interface concept.
