* @brief DAC HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of DAC extension peripheral:
* + Extended features functions
*
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(+) When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used simultaneously) :
Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
(+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
(+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
