◆ __HAL_SPI_RESET_HANDLE_STATE

#define __HAL_SPI_RESET_HANDLE_STATE (   __HANDLE__)    ((__HANDLE__)->State = HAL_SPI_STATE_RESET)

Reset SPI handle state.

Parameters
<strong>HANDLE</strong>specifies the SPI Handle. This parameter can be SPI where x: 1, 2, or 3 to select the SPI peripheral.
Return values
None

◆ __HAL_SPI_ENABLE_IT

#define __HAL_SPI_ENABLE_IT (   __HANDLE__,
  __INTERRUPT__ 
)    ((__HANDLE__)->Instance->CR2 |= (__INTERRUPT__))

Enable or disable the specified SPI interrupts.

Parameters
<strong>HANDLE</strong>specifies the SPI Handle. This parameter can be SPI where x: 1, 2, or 3 to select the SPI peripheral.
<strong>INTERRUPT</strong>specifies the interrupt source to enable or disable. This parameter can be one of the following values:
  • SPI_IT_TXE: Tx buffer empty interrupt enable
  • SPI_IT_RXNE: RX buffer not empty interrupt enable
  • SPI_IT_ERR: Error interrupt enable
Return values
None

◆ __HAL_SPI_DISABLE_IT

#define __HAL_SPI_DISABLE_IT (   __HANDLE__,

#define __HAL_SPI_GET_IT_SOURCE (   __HANDLE__,
  __INTERRUPT__ 
)    ((((__HANDLE__)->Instance->CR2 & (__INTERRUPT__)) == (__INTERRUPT__)) ? SET : RESET)

Check whether the specified SPI interrupt source is enabled or not.

Parameters
<strong>HANDLE</strong>specifies the SPI Handle. This parameter can be SPI where x: 1, 2, or 3 to select the SPI peripheral.
<strong>INTERRUPT</strong>specifies the SPI interrupt source to check. This parameter can be one of the following values:
  • SPI_IT_TXE: Tx buffer empty interrupt enable
  • SPI_IT_RXNE: RX buffer not empty interrupt enable
  • SPI_IT_ERR: Error interrupt enable
Return values
Thenew state of IT (TRUE or FALSE).

◆ __HAL_SPI_GET_FLAG

#define __HAL_SPI_GET_FLAG (   __HANDLE__,
  __FLAG__ 
)    ((((__HANDLE__)->Instance->SR) & (__FLAG__)) == (__FLAG__))

Check whether the specified SPI flag is set or not.

Parameters
<strong>HANDLE</strong>specifies the SPI Handle. This parameter can be SPI where x: 1, 2, or 3 to select the SPI peripheral.
<strong>FLAG</strong>specifies the flag to check. This parameter can be one of the following values:
  • SPI_FLAG_RXNE: Receive buffer not empty flag
  • SPI_FLAG_TXE: Transmit buffer empty flag
  • SPI_FLAG_CRCERR: CRC error flag
  • SPI_FLAG_MODF: Mode fault flag
  • SPI_FLAG_OVR: Overrun flag
  • SPI_FLAG_BSY: Busy flag
  • SPI_FLAG_FRE: Frame format error flag
Return values
Thenew state of FLAG (TRUE or FALSE).
