  *                                 How to use this driver
  *          ===================================================================
  *          1. Enable peripheral clock using CLK_PeripheralClockConfig(CLK_Peripheral_I2Cx,
  *             ENABLE) function (Refer to the product datasheet for the available I2C
  *           	peripherals)
  *
  *
  *          2. Program the Mode, duty cycle , Own address, Ack, Speed and Acknowledged
  *             Address using the I2C_Init() function.
  *
  *          3. Optionally you can enable/configure the following parameters without
  *             re-initialization (i.e there is no need to call again I2C_Init() function):
  *              - Enable the acknowledge feature using I2C_AcknowledgeConfig() function
  *              - Enable the dual addressing mode using I2C_DualAddressCmd() function
  *              - Enable the general call using the I2C_GeneralCallCmd() function
  *              - Enable the clock stretching using I2C_StretchClockCmd() function
  *              - Enable the fast mode duty cycle using the I2C_FastModeDutyCycleConfig()
  *                function
  *              - Enable the PEC Calculation using I2C_CalculatePEC() function
  *              - For SMBus Mode:
  *                   - Enable the Address Resolution Protocol (ARP) using I2C_ARPCmd() function
  *                   - Configure the SMBusAlert pin using I2C_SMBusAlertConfig() function
  *
  *          4. Enable the interrupt using the function I2C_ITConfig() if you need
  *             to use interrupt mode.
  *
  *          5. When using the DMA mode
  *                   - Configure the DMA using DMA_Init() function
  *                   - Active the needed channel Request using I2C_DMACmd() or
  *                     I2C_DMALastTransferCmd() function
  *              Note: When using DMA mode, I2C interrupts may be used at the same time to
  *                    control the communication flow (Start/Stop/Ack... events and errors).
  *
  *          6. Enable the I2C using the I2C_Cmd() function.
  *
  *          7. Enable the DMA using the DMA_Cmd() function when using DMA mode in the
  *             transfers.
  *
  *         Note: The external Pull-up resistors must be connected on SDA and SCL.
