AbstractData acquisition is a problem that is frequently encountered in the world of research and experimentation. There are many existing software applications that are abstract enough to handle data acquisition for a large range of scenarios, but sometimes a more specialized approach is needed. I designed the Data Logger application to be a lightweight standalone application to translate data sent from multiple serial-ports, which interface with IMUs (Inertial Measurement Units), and then record the data in log files. These log files would then be used during post experimental processing to determine conclusions based on IMU performance. This application was written in Java using only one external library, the Java Communications API (also known as javax.comm). The software was designed with extensibility in mind. This is to say that it would be easy for any other serial-port interfacing device (not just IMUs) to have its data recorded by Data Logger. All that’s required is for someone to implement the translation of the data streaming from the serial port. The software architecture is also setup so that it should be simple to add new modules to communicate with and record data from other sources, including different kinds of ports. Throughout design and implementation, a few concerns and problems were noticed and addressed. Solutions have been found for some, such as accurate time stamping, but there are other issues that remain unsolved, such as time-synchronization.
