bogdanm 0:9b334a45a8ff 16 [..]
bogdanm 0:9b334a45a8ff 17 (+) When Dual mode is enabled (i.e. DAC Channel1 and Channel2 are used simultaneously) :
bogdanm 0:9b334a45a8ff 18 Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
bogdanm 0:9b334a45a8ff 19 HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
bogdanm 0:9b334a45a8ff 20 (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
bogdanm 0:9b334a45a8ff 21 (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
bogdanm 0:9b334a45a8ff 22
bogdanm 0:9b334a45a8ff 23 (+) HAL_DACEx_SelfCalibrate to calibrate one DAC channel.
bogdanm 0:9b334a45a8ff 24 (+) HAL_DACEx_SetUserTrimming to set user trimming value.
bogdanm 0:9b334a45a8ff 25 (+) HAL_DACEx_GetTrimOffset to retrieve trimming value (factory setting
bogdanm 0:9b334a45a8ff 26 after reset, user setting if HAL_DACEx_SetUserTrimming have been used
bogdanm 0:9b334a45a8ff 27 at least one time after reset).
