                      ##### How to use this driver #####
  ==============================================================================
    [..]

     *** Dual mode IO operation ***
     ==============================
     [..]
      (+) Use HAL_DACEx_DualStart() to enable both channel and start conversion
          for dual mode operation.
          If software trigger is selected, using HAL_DACEx_DualStart() will start
          the conversion of the value previously set by HAL_DACEx_DualSetValue().
      (+) Use HAL_DACEx_DualStop() to disable both channel and stop conversion
          for dual mode operation.
      (+) Use HAL_DACEx_DualStart_DMA() to enable both channel and start conversion
          for dual mode operation using DMA to feed DAC converters.
          First issued trigger will start the conversion of the value previously
          set by HAL_DACEx_DualSetValue().
          The same callbacks that are used in single mode are called in dual mode to notify
          transfer completion (half complete or complete), errors or underrun.
      (+) Use HAL_DACEx_DualStop_DMA() to disable both channel and stop conversion
          for dual mode operation using DMA to feed DAC converters.
      (+) 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).
