/** @defgroup Communication Main / Communication
* @brief Control the communication with the computer.
*
* This module controls all the communication logic between the board and the
* computer. It uses a specific communication protocol between the
* computer and the board, with a system of messages. Thanks to this, the
* the MATLAB application is able to get the value of selected variables on the
* STM, and is even capable of modifiying them remotely.
*
* Make sure that the files communication.h/.c are up-to-date with the Excel
* spreadsheet "Protocol description.xlsx".
*
* Call comm_Init() to setup this module. Its interrupt function will be called
* automatically when a message arrives, or periodically when the data
* streaming is enabled.
