Function Documentation

void I2S_Cmd ( SPI_TypeDef SPIx,
FunctionalState  NewState 
)

Enables or disables the specified SPI peripheral (in I2S mode).

Parameters
SPIxwhere x can be 2 or 3 to select the SPI peripheral.
NewStatenew state of the SPIx peripheral. This parameter can be: ENABLE or DISABLE.
Return values
None

Definition at line 451 of file stm32f10x_spi.c.

void I2S_Init ( SPI_TypeDef SPIx,
