Functions

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.

Detailed Description

Data transfers management functions. 

 ===============================================================================
                ##### Data transfers management functions #####
 =============================================================================== 
    [..] This subsection provides a set of functions allowing to manage 
         the I2C data transfers.
         
    [..] The read access of the I2C_RXDR register can be done using 
         the I2C_ReceiveData() function and returns the received value.
         Whereas a write access to the I2C_TXDR can be done using I2C_SendData()
         function and stores the written data into TXDR.
