Function Documentation

void I2C_CalculatePEC	(	I2C_TypeDef *	I2Cx,
		FunctionalState	NewState
	)

Enables or disables the PEC value calculation of the transferred bytes.

Parameters

I2Cx,:	where x can be 1, 2 or 3 to select the I2C peripheral.
NewState,:	new state of the I2Cx PEC value calculation. This parameter can be: ENABLE or DISABLE.

Return values

None

uint8_t I2C_GetPEC

(

I2C_TypeDef *

I2Cx

)

Returns the PEC value for the specified I2C.

Parameters

I2Cx,:

where x can be 1, 2 or 3 to select the I2C peripheral.

Return values

The	PEC value.

void I2C_PECPositionConfig	(	I2C_TypeDef *	I2Cx,
		uint16_t	I2C_PECPosition
	)

Selects the specified I2C PEC position.

Parameters

I2Cx,:	where x can be 1, 2 or 3 to select the I2C peripheral.
I2C_PECPosition,:	specifies the PEC position. This parameter can be one of the following values: I2C_PECPosition_Next: indicates that the next byte is PEC I2C_PECPosition_Current: indicates that current byte is PEC

Note

This function configures the same bit (POS) as I2C_NACKPositionConfig() but is intended to be used in SMBUS mode while I2C_NACKPositionConfig() is intended to used in I2C mode.

Return values

None

void I2C_TransmitPEC	(	I2C_TypeDef *	I2Cx,
		FunctionalState	NewState
	)

Enables or disables the specified I2C PEC transfer.

Parameters

I2Cx,:	where x can be 1, 2 or 3 to select the I2C peripheral.
NewState,:	new state of the I2C PEC transmission. This parameter can be: ENABLE or DISABLE.

Return values

None
