__STATIC_INLINE void LL_DAC_TrigSWConversion	(	DAC_TypeDef *	DACx,
		uint32_t	DAC_Channel
	)

Trig DAC conversion by software for the selected DAC channel.

Note: Preliminarily, DAC trigger must be set to software trigger using function LL_DAC_Init() 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.
