                     ##### 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).
