LL DAC Generic Driver

DocID028236 Rev 2

835/1371

Noise mode and parameters LFSR (linear feedback shift register).

Parameters

DACx: DAC instance

DAC_Channel: This parameter can be one of the following

values:

LL_DAC_CHANNEL_1

LL_DAC_CHANNEL_2

NoiseLFSRMask: This parameter can be one of the

following values:

LL_DAC_NOISE_LFSR_UNMASK_BIT0

LL_DAC_NOISE_LFSR_UNMASK_BITS1_0

LL_DAC_NOISE_LFSR_UNMASK_BITS2_0

LL_DAC_NOISE_LFSR_UNMASK_BITS3_0

LL_DAC_NOISE_LFSR_UNMASK_BITS4_0

LL_DAC_NOISE_LFSR_UNMASK_BITS5_0

LL_DAC_NOISE_LFSR_UNMASK_BITS6_0

LL_DAC_NOISE_LFSR_UNMASK_BITS7_0

LL_DAC_NOISE_LFSR_UNMASK_BITS8_0

LL_DAC_NOISE_LFSR_UNMASK_BITS9_0

LL_DAC_NOISE_LFSR_UNMASK_BITS10_0

LL_DAC_NOISE_LFSR_UNMASK_BITS11_0

Return values

None:

Notes

For wave generation to be effective, DAC channel wave

generation mode must be enabled using function

LL_DAC_SetWaveAutoGeneration().

This setting can be set when the selected DAC channel is

disabled (otherwise, the setting operation is ignored).
