Tiivistelmä
This thesis details the implementation of a command and response analyzer for a Micro-Electromechanical Systems (MEMS) Inertial Measurement Unit (IMU) sensor. The tool processes and translates the messages exchanged between a host device and the sensor into a human-readable form. Commissioned by Robert Bosch Oy for internal use, the primary goal of the analyzer is to assist engineers by automating the communication decoding and acting as an extension tool to their existing workflow.
Furthermore, a key requirement was the ability to process the comma-separated values (CSV) log files exported from the Saleae protocol analyzer containing captured data from various bus interfaces. The implemented analyzer produces a chronologically structured Hypertext Markup Language (HTML) report, providing a detailed analysis of the data packets while highlighting relevant information, such as warnings and errors.
Lastly, the design of the tool emphasizes future expansion. It prioritizes software component reusability, allowing for the addition of new command analysis capabilities and the processing of logs from various sources. To ensure broad accessibility, the functionalities of the Command Interface Analyzer are accessible through a web interface on both Windows and Linux devices.
