Web interface for a multi-purpose transmitter

Sammanfattning: The project described in this report aims to construct a web interface for a multi-purpose transmitter (MPT). The MPT is a submodule that is meant to be used in future chromatography systems. This bachelor thesis project is done at Cytiva in Uppsala. The MPT uses the Azure RTOS development suite with ThreadX as the RTOS, FileX as the file system, and NetX for the TCP/IP protocol stack implementation. The Azure RTOS platform facilitates development for deeply embedded systems and comes with extensive documentation for their services. The web interface consists of 5 web pages with 5 different use cases: Overview for visualization of basic data; Data for visualization, recording, and filtering of all data; Update page for firmware update and file management; Log for development logging purposes; and Config for modifying parameters and running module diagnostic tests. Development of the front end was done in Visual Studio Code. The workflow was streamlined by developing a tool at the beginning of the project that combines the files for the front-end code into variables stored in C source files. Testing of new features was aided by a Python Flask server developed in parallel to the main back end. It embodies the same functionality as the main back end, aside from being hosted on a local computer. The web interface will mainly be used by customers and service personnel. This requires the interface to have two different access levels. The Overview page can be accessed without any authorization while the other pages require the user to be authenticated via username and password.
