void HAL_DFSDM_BitstreamClock_Start ( void )

Select the DFSDM2 as clock source for the bitstream clock.

Note: The SYSCFG clock marco __HAL_RCC_SYSCFG_CLK_ENABLE() must be called before HAL_DFSDM_BitstreamClock_Start()

Definition at line 3717 of file stm32f4xx_hal_dfsdm.c.

◆ HAL_DFSDM_BitstreamClock_Stop()

void HAL_DFSDM_BitstreamClock_Stop ( void )

Stop the DFSDM2 as clock source for the bitstream clock.

Note: The SYSCFG clock marco __HAL_RCC_SYSCFG_CLK_ENABLE() must be called before HAL_DFSDM_BitstreamClock_Stop()

Return values

None

Definition at line 3733 of file stm32f4xx_hal_dfsdm.c.

◆ HAL_DFSDM_ClockIn_SourceSelection()

void HAL_DFSDM_ClockIn_SourceSelection ( uint32_t source )

Select the source for CKin signals for DFSDM1/2.

Parameters

source DFSDM2_CKIN_PAD. DFSDM2_CKIN_DM. DFSDM1_CKIN_PAD. DFSDM1_CKIN_DM.

Return values

None

Definition at line 3798 of file stm32f4xx_hal_dfsdm.c.

◆ HAL_DFSDM_ClockOut_SourceSelection()

void HAL_DFSDM_ClockOut_SourceSelection ( uint32_t source )

Select the source for CKOut signals for DFSDM1/2.

Parameters

source DFSDM2_CKOUT_DFSDM2. DFSDM2_CKOUT_M27. DFSDM1_CKOUT_DFSDM1. DFSDM1_CKOUT_M27.

Definition at line 3831 of file stm32f4xx_hal_dfsdm.c.

◆ HAL_DFSDM_ConfigMultiChannelDelay()

void HAL_DFSDM_ConfigMultiChannelDelay ( DFSDM_MultiChannelConfigTypeDef * mchdlystruct )

Configure multi channel delay block: Use DFSDM2 audio clock source as input clock for DFSDM1 and DFSDM2 filters to Synchronize DFSDMx filters. Set the path of the DFSDM2 clock output (dfsdm2_ckout) to the DFSDM1/2 CkInx and data inputs channels by configuring following MCHDLY muxes or demuxes: M1, M2, M3, M4, M5, M6, M7, M8, DM1, DM2, DM3, DM4, DM5, DM6, M9, M10, M11, M12, M13, M14, M15, M16, M17, M18, M19, M20 based on the contains of the DFSDM_MultiChannelConfigTypeDef structure.

Parameters

mchdlystruct Structure of multi channel configuration

Return values

None

Note: The SYSCFG clock marco __HAL_RCC_SYSCFG_CLK_ENABLE() must be called before HAL_DFSDM_ConfigMultiChannelDelay(); The HAL_DFSDM_ConfigMultiChannelDelay() function clears the SYSCFG-MCHDLYCR register before setting the new configuration.
