	/** @defgroup UART Driver / UART
	* @brief Driver for the UART serial communication peripheral.
	*
	* This driver controls the UART peripheral of the STM32, connected to the
	* USB-to-serial chip.
	*
	* Call uart_Init() first in the initialization code, specifiying the function
	* to call when a byte arrives (sent from the computer). To send data, call
	* uart_SendByte() or uart_SendBytes().
	*
	* Note that this module should not be used directly. It is a better option to
	* use it through the Communication module, to benefit from the already
	* implemented communication protocol between the board and MATLAB.
