| * @brief DAC HAL module driver. |
| * This file provides firmware functions to manage the extended |
| * functionalities of the DAC peripheral. |

| @verbatim |
| ============================================================================== |
| ##### How to use this driver ##### |
| ============================================================================== |
| [..] |
| *** Dual mode IO operation *** |
| ============================== |
| (+) 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. |
| |
| *** Signal generation operation *** |
| =================================== |
| (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal. |
| (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal. |
