  ==============================================================================
    [..]          
      (+) 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.
