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()
