DocID028236 Rev 2
DAC_Channel, LL_DAC_InitTypeDef * DAC_InitStruct)
Function description
Initialize some features of DAC instance.
Parameters
DACx: DAC instance
DAC_Channel: This parameter can be one of the following
values:
LL_DAC_CHANNEL_1
LL_DAC_CHANNEL_2
DAC_InitStruct: Pointer to a LL_DAC_InitTypeDef structure
Return values
An: ErrorStatus enumeration value:
SUCCESS: DAC registers are initialized
ERROR: DAC registers are not initialized
Notes
The setting of these parameters by function LL_DAC_Init() is
conditioned to DAC state: DAC instance must be disabled.
LL_DAC_StructInit
Function name
void LL_DAC_StructInit (LL_DAC_InitTypeDef *
DAC_InitStruct)
Function description
Set each LL_DAC_InitTypeDef field to default value.
Parameters
DAC_InitStruct: pointer to a LL_DAC_InitTypeDef structure
whose fields will be set to default values.
Return values
None:
