## 函数说明

## ◆ SPI_Cmd()

void SPI_Cmd | ( | SPI_TypeDef * | SPIx,
|  | FunctionalState | NewState
| ) |  |

Enables or disables the specified SPI peripheral.

参数

  SPIx | Pointer to selected SPI peripheral. This parameter can be one of the following values: SPI.
  NewState | new state of the SPIx peripheral. This parameter can be: ENABLE or DISABLE.

返回值

  None |

## ◆ SPI_DeInit()

void SPI_DeInit | ( | SPI_TypeDef * | SPIx | ) |

## ◆ SPI_GetFlagStatus()

FlagStatus SPI_GetFlagStatus | ( | SPI_TypeDef * | SPIx,
|  | uint8_t | SPI_FLAG
| ) |  |

Checks whether the specified SPIx flag is set or not.

参数

  SPIx | Pointer to selected SPI peripheral. This parameter can be one of the following values: SPI.
  SPI_FLAG | specifies the SPI flag to check. This parameter can be one of the following values: SPI_FLAG_SPIF: End of transmission flag. SPI_FLAG_WCOL: Write conflict flag. SPI_FLAG_SSERR: Slave mode SSN error flag. SPI_FLAG_MDF: Host mode error flag.

返回值
