|
+ ##### How to use this driver #####
|
|
|
+ ==============================================================================
|
|
|
+ [..]
|
|
|
+ *** Dual mode IO operation ***
|
|
|
+ ==============================
|
|
|
+ [..]
|
|
|
+ (+) Use HAL_DACEx_DualStart() to enable both channel and start conversion
|
|
|
+ for dual mode operation.
|
|
|
+ If software trigger is selected, using HAL_DACEx_DualStart() will start
|
|
|
+ the conversion of the value previously set by HAL_DACEx_DualSetValue().
|
|
|
+ (+) Use HAL_DACEx_DualStop() to disable both channel and stop conversion
|
|
|
+ for dual mode operation.
|
|
|
+ (+) Use HAL_DACEx_DualStart_DMA() to enable both channel and start conversion
|
|
|
+ for dual mode operation using DMA to feed DAC converters.
|
|
|
+ First issued trigger will start the conversion of the value previously
|
|
|
+ set by HAL_DACEx_DualSetValue().
|
|
|
+ The same callbacks that are used in single mode are called in dual mode to notify
|
|
|
+ transfer completion (half complete or complete), errors or underrun.
|
|
|
+ (+) Use HAL_DACEx_DualStop_DMA() to disable both channel and stop conversion
|
|
|
+ for dual mode operation using DMA to feed DAC converters.
|
|
|
+ (+) 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).
