| 12 | ##### How to use this driver ##### |
||
| 13 | ============================================================================== |
||
| 14 | [..] |
||
| 15 | *** Dual mode IO operation *** |
||
| 16 | ============================== |
||
| 17 | (+) When Dual mode is enabled (i.e. DAC Channel1 and Channel2 are used simultaneously) : |
||
| 18 | Use HAL_DACEx_DualGetValue() to get digital data to be converted and use |
||
| 19 | HAL_DACEx_DualSetValue() to set digital value to converted simultaneously in |
||
| 20 | Channel 1 and Channel 2. |
||
| 21 | |||
| 22 | *** Signal generation operation *** |
||
| 23 | =================================== |
||
| 24 | (+) Use HAL_DACEx_TriangleWaveGenerate() to generate Triangle signal. |
||
| 25 | (+) Use HAL_DACEx_NoiseWaveGenerate() to generate Noise signal. |
