一种单总线接口时序分析仪的研制

Design and Implementation of Analyzer of 1-Wire Bus Timing

设计了一种单总线信号分离电路,可将单总线上的双向信号根据发送端的不同而分离出来,采用嵌入式ARM系统研制了单总线时序分析仪,对分离电路输出的各个发送端信号进行独立采集与分析,实现了对单总线接口信号的时序与数据分析。

A special circuit is designed to extract and distinguish the signal sources from those ends connected with the 1 -Wire bus; A analyzer based on ARM MCU can analysis 1 - Wire bus timing sequence. The analyzer can get the period of the signal and the timing alternating and realize the analyse of 1 - Wire Bus timing.
