摘　　要：详细介绍了如何利用AVR微控器ATmega16的通用IO口,结合硬件上的电平转换与安全隔离措施,再辅之以软件的时序处理和串行移位输入、输出,从而实现了与SSI数据协议传感器的无缝衔接。本文的软件代码虽然是针对磁滞伸缩位移传感器编写的,但其相应的软硬件处理方式、方法可以推广到其它类型的SSI协议的传感器,并可保证读取数据的可靠性和稳定性。It is introduced in the paper how to use the general 10 ports of AVR microcontroller ATmegal6, combined with the level convemion and safety isolation in hardware, the sequential processing in software and input/output of serial shift, to realize the connection with SSI data protocol sensor. Although the software code in the paper is written for magnetostrictive displacement sensor, the corresponding approach and method of software and hardware can be extended to other types of SSI protocol sensors, and can ensure the reliability and stability of data.
