* @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. | |
