* This file provides firmware functions to manage the extended | |
* functionalities of the DAC peripheral. | |

============================================================================== | |
##### 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. | |
