LL_DAC_SetTriggerSource() function

Set the conversion trigger source for the selected DAC channel. (1) On this STM32 series, parameter not available on all devices. Refer to device datasheet for channels availability.

Syntax

from stm32f4xx_ll_dac.h:554

__STATIC_INLINE void LL_DAC_SetTriggerSource(DAC_TypeDef *DACx, uint32_t DAC_Channel, uint32_t TriggerSource);

Arguments

DACx

DAC instance

DAC_Channel

This parameter can be one of the following values: @arg LL_DAC_CHANNEL_1 @arg LL_DAC_CHANNEL_2 (1)

TriggerSource

This parameter can be one of the following values: @arg LL_DAC_TRIG_SOFTWARE @arg LL_DAC_TRIG_EXT_TIM8_TRGO @arg LL_DAC_TRIG_EXT_TIM7_TRGO @arg LL_DAC_TRIG_EXT_TIM6_TRGO @arg LL_DAC_TRIG_EXT_TIM5_TRGO @arg LL_DAC_TRIG_EXT_TIM4_TRGO @arg LL_DAC_TRIG_EXT_TIM2_TRGO @arg LL_DAC_TRIG_EXT_EXTI_LINE9

Return value

None

Notes

For conversion trigger source to be effective, DAC trigger must be enabled using function LL_DAC_EnableTrigger(). To set conversion trigger source, DAC channel must be disabled. Otherwise, the setting is discarded. Availability of parameters of trigger sources from timer depends on timers availability on the selected device. CR TSEL2 LL_DAC_SetTriggerSource
