			* @brief Driver for the digital-to-analog converter.
			*
			* The STM32 features a two channels DAC, which means it is able to drive two
			* pins with an analog voltage. On the HRI board, this voltage is mulltiplied
			* by an amplification stage, so the final output range is +-9V. The
			* corresponding output pins are on the J1 connector: ANOUT1 (2) and ANOUT2 (4).
			*
			* In the initialization code, call dac_Init() once. Then call
			* dac_GetVoltageX() everytime the output voltage needs to be updated.
			*
			* @addtogroup DAC
