bogdanm 0:9b334a45a8ff 17 [..]
bogdanm 0:9b334a45a8ff 18 (+) When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used simultaneously) :
bogdanm 0:9b334a45a8ff 19 Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
bogdanm 0:9b334a45a8ff 20 HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
bogdanm 0:9b334a45a8ff 21 (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
bogdanm 0:9b334a45a8ff 22 (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
