Detailed Description

Initialization and Configuration functions.

 ===============================================================================
              ##### Initialization and de-initialization functions #####
 ===============================================================================
    [..]  This subsection provides a set of functions allowing to initialize and
          de-initialize the I2Cx peripheral:

      (+) User must Implement HAL_I2C_MspInit() function in which he configures
          all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC).

      (+) Call the function HAL_I2C_Init() to configure the selected device with
          the selected configuration:
        (++) Communication Speed
        (++) Duty cycle
        (++) Addressing mode
        (++) Own Address 1
        (++) Dual Addressing mode
        (++) Own Address 2
        (++) General call mode
        (++) Nostretch mode

      (+) Call the function HAL_I2C_DeInit() to restore the default configuration
          of the selected I2Cx peripheral.
