                     ##### 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).
