* @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 ##### | |
============================================================================== | |
[..] | |
(+) 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. | |
(+) HAL_DACEx_SelfCalibrate to calibrate one DAC channel. | |
(+) HAL_DACEx_SetUserTrimming to set user trimming value. | |
(+) HAL_DACEx_GetTrimOffset to retrieve trimming value (factory setting | |
after reset, user setting if HAL_DACEx_SetUserTrimming have been used | |
at least one time after reset). | |
