◆ __HAL_DMA_DISABLE

#define __HAL_DMA_DISABLE (   __HANDLE__)    (CLEAR_BIT((__HANDLE__)->Instance->CCR, DMA_CCR_EN))

Disable the specified DMA Channel.

Parameters
<strong>HANDLE</strong>DMA handle
Return values
None

Definition at line 303 of file stm32f1xx_hal_dma.h.

◆ __HAL_DMA_DISABLE_IT

#define __HAL_DMA_DISABLE_IT (   __HANDLE__,
  __INTERRUPT__ 
)    (CLEAR_BIT((__HANDLE__)->Instance->CCR , (__INTERRUPT__)))

Disable the specified DMA Channel interrupts.

Parameters

Enables the specified DMA Channel interrupts.

Parameters
<strong>HANDLE</strong>DMA handle
<strong>INTERRUPT</strong>specifies the DMA interrupt sources to be enabled or disabled. This parameter can be any combination of the following values:
  • DMA_IT_TC: Transfer complete interrupt mask
  • DMA_IT_HT: Half transfer complete interrupt mask
  • DMA_IT_TE: Transfer error interrupt mask
Return values
None

◆ __HAL_DMA_GET_COUNTER

#define __HAL_DMA_GET_COUNTER (   __HANDLE__)    ((__HANDLE__)->Instance->CNDTR)

Return the number of remaining data units in the current DMA Channel transfer.

Parameters
<strong>HANDLE</strong>DMA handle
Return values
Thenumber of remaining data units in the current DMA Channel transfer.

Check whether the specified DMA Channel interrupt is enabled or not.

Parameters
<strong>HANDLE</strong>DMA handle
<strong>INTERRUPT</strong>specifies the DMA interrupt source to check. This parameter can be one of the following values:
  • DMA_IT_TC: Transfer complete interrupt mask
  • DMA_IT_HT: Half transfer complete interrupt mask
  • DMA_IT_TE: Transfer error interrupt mask
Return values
Thestate of DMA_IT (SET or RESET).
