应用于磁致伸缩传感器的SSI-USB转换器

摘要

In order to achieve the interaction between the host computer with the magnetostrictive sensor, this paper developed a SSI - USB converter which was controlled by high-end 8-bit microcontroller ATmega128.Through the study of SSI protocol specification, as weU as the study of the USB interface circuit which was realized by PDIUSBD12.the related hardware and software design was presented.Ultimately it achieves the conversion between SSI signal and USB signal, thus it achieves the communication between magnetostrictive sensor and PC.%为了实现磁致伸缩传感器与上位机的交互,研制了一种由高档8位单片机ATmega128控制的SSI-USB转换器.通过对SSI协议规范的研究,以及对由PDIUSBD12实现的USB接口电路的研究,提出了相关的软硬件设计.最终实现了SSI信号与USB信号的相互转换,从而实现了磁致伸缩传感器与上位机的通信.
