Return values
HAL: status
HAL_DACEx_DualSetValue
Function name
HAL_StatusTypeDef HAL_DACEx_DualSetValue
(DAC_HandleTypeDef * hdac, uint32_t Alignment, uint32_t
Data1, uint32_t Data2)
Function description
Set the specified data holding register value for dual DAC channel.
Parameters
hdac: pointer to a DAC_HandleTypeDef structure that
contains the configuration information for the specified DAC.
Alignment: Specifies the data alignment for dual channel
DAC. This parameter can be one of the following values:
DAC_ALIGN_8B_R: 8bit right data alignment selected
DAC_ALIGN_12B_L: 12bit left data alignment selected
DAC_ALIGN_12B_R: 12bit right data alignment selected
Data1: Data for DAC Channel2 to be loaded in the selected
data holding register.
Data2: Data for DAC Channel1 to be loaded in the selected
data holding register.
Return values
HAL: status
Notes
In dual mode, a unique register access is required to write in
both DAC channels at the same time.
HAL_DACEx_ConvCpltCallbackCh2
Function name
void HAL_DACEx_ConvCpltCallbackCh2
(DAC_HandleTypeDef * hdac)
Function description
Conversion complete callback in non blocking mode for Channel2.
Parameters
hdac: pointer to a DAC_HandleTypeDef structure that
contains the configuration information for the specified DAC.
