uint32_t LL_DAC_InitTypeDef::TriggerSource
Set the conversion trigger source for the selected DAC channel: internal (SW start) or
from external IP (timer event, external interrupt line). This parameter can be a value of
DAC_LL_EC_TRIGGER_SOURCEThis feature can be modified afterwards using
unitary function LL_DAC_SetTriggerSource().
uint32_t LL_DAC_InitTypeDef::WaveAutoGeneration
Set the waveform automatic generation mode for the selected DAC channel. This
parameter can be a value of DAC_LL_EC_WAVE_AUTO_GENERATION_MODEThis
feature can be modified afterwards using unitary function
LL_DAC_SetWaveAutoGeneration().
uint32_t LL_DAC_InitTypeDef::WaveAutoGenerationConfig
Set the waveform automatic generation mode for the selected DAC channel. If
waveform automatic generation mode is set to noise, this parameter can be a value of
DAC_LL_EC_WAVE_NOISE_LFSR_UNMASK_BITS If waveform automatic
generation mode is set to triangle, this parameter can be a value of
DAC_LL_EC_WAVE_TRIANGLE_AMPLITUDE
Note:If waveform automatic generation mode is disabled, this parameter is discarded.
This feature can be modified afterwards using unitary function
LL_DAC_SetWaveNoiseLFSR() or LL_DAC_SetWaveTriangleAmplitude(),
depending on the wave automatic generation selected.
uint32_t LL_DAC_InitTypeDef::OutputBuffer
Set the output buffer for the selected DAC channel. This parameter can be a value of
DAC_LL_EC_OUTPUT_BUFFERThis feature can be modified afterwards using
unitary function LL_DAC_SetOutputBuffer().
