13 HAL DAC Extension Driver
13.1 DACEx Firmware driver API description
13.1.1 How to use this driver
When Dual mode is enabled (i.e DAC Channel1 and Channel2 are used
simultaneously) : Use HAL_DACEx_DualGetValue() to get digital data to be converted
and use HAL_DACEx_DualSetValue() to set digital value to converted simultaneously
in Channel 1 and Channel 2.
Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal.
Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal.
13.1.2 Extended features functions
This section provides functions allowing to:
Start conversion.
Stop conversion.
Start conversion and enable DMA transfer.
Stop conversion and disable DMA transfer.
Get result of conversion.
Get result of dual mode conversion.
This section contains the following APIs:
HAL_DACEx_DualGetValue()
HAL_DACEx_TriangleWaveGenerate()
HAL_DACEx_NoiseWaveGenerate()
HAL_DACEx_DualSetValue()
HAL_DACEx_ConvCpltCallbackCh2()
