mbed_official 610:813dcc80987e 14 ##### How to use this driver #####
mbed_official 610:813dcc80987e 15 ==============================================================================
mbed_official 610:813dcc80987e 16 [..]
mbed_official 610:813dcc80987e 17 (+) When Dual mode is enabled (i.e. DAC Channel1 and Channel2 are used simultaneously) :
mbed_official 610:813dcc80987e 18 Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
mbed_official 610:813dcc80987e 19 HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
mbed_official 610:813dcc80987e 20 (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
mbed_official 610:813dcc80987e 21 (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
mbed_official 610:813dcc80987e 22
mbed_official 610:813dcc80987e 23 (+) HAL_DACEx_SelfCalibrate to calibrate one DAC channel.
mbed_official 610:813dcc80987e 24 (+) HAL_DACEx_SetUserTrimming to set user trimming value.
mbed_official 610:813dcc80987e 25 (+) HAL_DACEx_GetTrimOffset to retrieve trimming value (factory setting
mbed_official 610:813dcc80987e 26 after reset, user setting if HAL_DACEx_SetUserTrimming have been used
mbed_official 610:813dcc80987e 27 at least one time after reset).
