15 ##### How to use this driver #####
|
|
16 ==============================================================================
|
|
17 [..]
|
|
18 (+) When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used simultaneously) :
|
|
19 Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
|
|
20 HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in Channel 1 and Channel 2.
|
|
21 (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
|
|
22 (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
