	Enables or disables the specified I2C peripheral.
void	I2C_DMACmd (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Enables or disables the specified I2C DMA requests.
void	I2C_DMALastTransferCmd (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Specifies if the next DMA transfer will be the last one.
void	I2C_GenerateSTART (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Generates I2Cx communication START condition.
void	I2C_GenerateSTOP (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Generates I2Cx communication STOP condition.
void	I2C_AcknowledgeConfig (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Enables or disables the specified I2C acknowledge feature.
void	I2C_OwnAddress2Config (I2C_TypeDef *I2Cx, uint8_t Address)
	Configures the specified I2C own address2.
void	I2C_DualAddressCmd (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Enables or disables the specified I2C dual addressing mode.
void	I2C_GeneralCallCmd (I2C_TypeDef *I2Cx, FunctionalState NewState)
	Enables or disables the specified I2C general call feature.
void	I2C_ITConfig (I2C_TypeDef *I2Cx, uint16_t I2C_IT, FunctionalState NewState)
	Enables or disables the specified I2C interrupts.
void	I2C_SendData (I2C_TypeDef *I2Cx, uint8_t Data)
	Sends a data byte through the I2Cx peripheral.
uint8_t	I2C_ReceiveData (I2C_TypeDef *I2Cx)
	Returns the most recent received data by the I2Cx peripheral.
void	I2C_Send7bitAddress (I2C_TypeDef *I2Cx, uint8_t Address, uint8_t I2C_Direction)
	Transmits the address byte to select the slave device.
