                      ##### How to use this driver #####
  ==============================================================================
    [..]
     *** Dual mode IO operation ***
     ==============================
      (+) 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.

     *** Signal generation operation ***
     ===================================
      (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
      (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.

      (+) HAL_DACEx_SelfCalibrate to calibrate one DAC channel.
      (+) HAL_DACEx_SetUserTrimming to set user trimming value.
      (+) HAL_DACEx_GetTrimOffset to retrieve trimming value (factory setting
          after reset, user setting if HAL_DACEx_SetUserTrimming have been used
          at least one time after reset).
