Return the current DMA Stream transfer error flag.

Parameters
<strong>HANDLE</strong>DMA handle
Return values
Thespecified transfer error flag index.

Definition at line 466 of file stm32f7xx_hal_dma.h.

#define __HAL_DMA_RESET_HANDLE_STATE (   __HANDLE__)    ((__HANDLE__)->State = HAL_DMA_STATE_RESET)

Reset DMA handle state.

Parameters
<strong>HANDLE</strong>specifies the DMA handle.
Return values
None

Definition at line 389 of file stm32f7xx_hal_dma.h.

#define __HAL_DMA_SET_COUNTER (   __HANDLE__,
  __COUNTER__ 
)    ((__HANDLE__)->Instance->NDTR = (uint16_t)(__COUNTER__))

Writes the number of data units to be transferred on the DMA Stream.

Parameters
<strong>HANDLE</strong>DMA handle
<strong>COUNTER</strong>Number of data units to be transferred (from 0 to 65535) Number of data items depends only on the Peripheral data format.
Note
If Peripheral data format is Bytes: number of data units is equal to total number of bytes to be transferred.
If Peripheral data format is Half-Word: number of data units is equal to total number of bytes to be transferred / 2.
If Peripheral data format is Word: number of data units is equal to total number of bytes to be transferred / 4.
Return values
Thenumber of remaining data units in the current DMAy Streamx transfer.
