|
##### 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.
