Trig DAC conversion by software for the selected DAC channel.

Note:

Preliminarily, DAC trigger must be set to software trigger using function LL_DAC_SetTriggerSource() with parameter "LL_DAC_TRIGGER_SOFTWARE". and DAC trigger must be enabled using function LL_DAC_EnableTrigger().

For devices featuring DAC with 2 channels: this function can perform a SW start of both DAC channels simultaneously. Two channels can be selected as parameter. Example: (LL_DAC_CHANNEL_1 | LL_DAC_CHANNEL_2) SWTRIGR SWTRIG1 LL_DAC_TrigSWConversion
SWTRIGR SWTRIG2 LL_DAC_TrigSWConversion

Parameters:

DACx	DAC instance
DAC_Channel	This parameter can a combination of the following values: LL_DAC_CHANNEL_1 LL_DAC_CHANNEL_2 (1) (1) On this STM32 family, parameter not available on all devices. Refer to device datasheet for channels availability.
