Detailed Description
Initialization and Configuration functions.
=============================================================================== ##### Initialization and de-initialization functions ##### =============================================================================== [..] This subsection provides a set of functions allowing to initialize and deinitialize 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: (++) Clock Timing (++) Own Address 1 (++) Addressing mode (Master, Slave) (++) Dual Addressing mode (++) Own Address 2 (++) Own Address 2 Mask (++) General call mode (++) Nostretch mode (+) Call the function HAL_I2C_DeInit() to restore the default configuration of the selected I2Cx peripheral.
