7.2.6.9 DAC_SetChannel2Data
Function Name
void DAC_SetChannel2Data ( uint32_t DAC_Align, uint16_t
Data)
Function Description
Sets the specified data holding register value for DAC channel2.
Parameters
 DAC_Align : Specifies the data alignment for DAC channel2.
This parameter can be:
 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
 Data : Data to be loaded in the selected data holding
register.
Return values
 None.
Notes
 None.
7.2.6.10 DAC_SetDualChannelData
Function Name
void DAC_SetDualChannelData ( uint32_t DAC_Align, uint16_t
Data2, uint16_t Data1)
Function Description
Sets the specified data holding register value for dual channel
DAC.
Parameters
 DAC_Align : Specifies the data alignment for dual channel
DAC. This parameter can be:
 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
 Data2 : Data for DAC Channel2 to be loaded in the selected
data holding register.
 Data1 : Data for DAC Channel1 to be loaded in the selected
data holding register.
Return values
 None.
Notes
 In dual mode, a unique register access is required to write in
both DAC channels at the same time.
