+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The FMPI2C HAL driver can be used as follows:
+
+ (#) Declare a FMPI2C_HandleTypeDef handle structure, for example:
+ FMPI2C_HandleTypeDef hfmpi2c;
+
+ (#)Initialize the FMPI2C low level resources by implement the HAL_FMPI2C_MspInit ()API:
+ (##) Enable the FMPI2Cx interface clock
+ (##) FMPI2C pins configuration
+ (+++) Enable the clock for the FMPI2C GPIOs
+ (+++) Configure FMPI2C pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the FMPI2Cx interrupt priority
+ (+++) Enable the NVIC FMPI2C IRQ Channel
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
+ (+++) Enable the DMAx interface clock using
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx or Rx Stream
+ (+++) Associate the initilalized DMA handle to the hfmpi2c DMA Tx or Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
+
+ (#) Configure the Communication Clock Timing, Own Address1, Master Adressing Mode, Dual Addressing mode,
+ Own Address2, Own Address2 Mask, General call and Nostretch mode in the hfmpi2c Init structure.
+
+ (#) Initialize the FMPI2C registers by calling the HAL_FMPI2C_Init() API:
+ (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+ by calling the customed HAL_FMPI2C_MspInit(&hfmpi2c) API.
+
+ (#) To check if target device is ready for communication, use the function HAL_FMPI2C_IsDeviceReady()
+
