Instrument Director - ACADIA Instrument Software Project (IDEXX)

As part of the R&D Instrument Software organization at IDEXX, I worked on the "Instrument Director" implementation as part of a new veterinary instrument development project (Acadia). Instrument Director is an embedded software (installed on the instrument) that plays the role of an orchestration engine. It is a brain of the (otherwise dead) instrument - bringing it to life; it manages multiple operational workflows and reacts to all real-time system events (both external and internal).
Instrument Director is implemented in Python and uses libraries/packages developed by other teams (some are C/C++, some are Python). Pybind11 library is used to bind C++ libraries and make them available via Python calls.
The project uses multithreading (and in some cases multiprocessing) to be able to react to all events as they occur while allowing its core engine to do its work at the same time. There's a small REST API component (developed using Flask) that enables internal clients (manufacturing, operations, and QA) to configure the device and its individual components and to execute different scripts during the build/manufacturing process and testing.
ID calls algorithm libraries were developed by the algorithm team to generate test results.
