HAL_DFSDM_FilterRegularStart_DMA() function
This function allows to start regular conversion in DMA mode.
Syntax
HAL_StatusTypeDef HAL_DFSDM_FilterRegularStart_DMA(DFSDM_Filter_HandleTypeDef *hdfsdm_filter,
int32_t *pData,
uint32_t Length);
Implemented in ![]()
stm32f4xx_hal_dfsdm.c:2453
Return value
HAL status
Notes
This function should be called only when DFSDM filter instance is in idle state or if injected conversion is ongoing. Please note that data on buffer will contain signed regular conversion value on 24 most significant bits and corresponding channel on 3 least significant bits.
