mbed_official 87:085cde657901 17 [..]
mbed_official 87:085cde657901 18 (+) When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used simultaneously) :
mbed_official 87:085cde657901 19 Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
mbed_official 87:085cde657901 20 HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
mbed_official 87:085cde657901 21 (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
mbed_official 87:085cde657901 22 (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
