This document aims to provide a guideline for people wanting to contribute to the project. It does not aim to describe the project, please see the README.md for this.
Before diving into the code a good starting point for understanding what the project is about and what one of the use cases is, you can play with the live decode in javascript called tmbus. This will provide a good intuition for what the project is about. Go to the folder tests/rscada/test-frames and copy the hex string into the input field of the tmbus website. See what the expected output is. Try to undestand the output. Change the input and see how the output changes. Note, becasue there is a check sum changing the input manually is not trivial and requires calculating the right checksum for the frame.
Code of conduct is taken from the rust project code of conduct.
