- * @author MCD Application Team
- * @version V1.0.0
- * @date 5-September-2014
- * @brief DAC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of DAC extension peripheral:
- * + Extended features functions
- *
- *
- @verbatim
- ==============================================================================
- ##### 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.
