##### 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.
|
|
|
|
(+) 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).
|
|
