Field Documentation

 uint32_t DAC_InitTypeDef::DAC_Trigger

 Specifies the external trigger for the selected DAC channel. This parameter can

be a value of DAC_trigger_selection

 uint32_t DAC_InitTypeDef::DAC_WaveGeneration

 Specifies whether DAC channel noise waves or triangle waves are generated, or

whether no wave is generated. This parameter can be a value of

DAC_wave_generation

 uint32_t DAC_InitTypeDef::DAC_LFSRUnmask_TriangleAmplitude

 Specifies the LFSR mask for noise wave generation or the maximum amplitude

triangle generation for the DAC channel. This parameter can be a value of

DAC_lfsrunmask_triangleamplitude

 uint32_t DAC_InitTypeDef::DAC_OutputBuffer

 Specifies whether the DAC channel output buffer is enabled or disabled. This

parameter can be a value of DAC_output_buffer

7.2 DAC Firmware driver API description

The following section lists the various functions of the DAC library.

7.2.1 DAC Peripheral features

The device integrates two 12-bit Digital Analog Converters that can be used independently

or simultaneously (dual mode):

1. DAC channel1 with DAC_OUT1 as output

2. DAC channel2 with DAC_OUT2 as output
