FMPI2C HAL module driver. This file provides firmware functions to manage the following functionalities of the Inter Integrated Circuit (FMPI2C) peripheral: + Initialization and de-initialization functions + IO operation functions + Peripheral State and Errors functions.
==============================================================================
##### 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 implementing 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 initialized 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 Addressing 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(), configures also the low level Hardware
(GPIO, CLOCK, NVIC...etc) by calling the customized HAL_FMPI2C_MspInit(&hfmpi2c) API.
(#) To check if target device is ready for communication, use the function HAL_FMPI2C_IsDeviceReady()
(#) For FMPI2C IO and IO MEM operations, three operation modes are available within this driver :
*** Polling mode IO operation ***
=================================
[..]
(+) Transmit in master mode an amount of data in blocking mode using HAL_FMPI2C_Master_Transmit()

This action will inform Master to generate a Stop condition to discard the communication.
*** Interrupt mode IO sequential operation ***
==============================================
[..]
(@) These interfaces allow to manage a sequential transfer with a repeated start condition
when a direction change during transfer
[..]
(+) A specific option field manage the different steps of a sequential transfer
(+) Option field values are defined through @ref FMPI2C_XFEROPTIONS and are listed below:
(++) FMPI2C_FIRST_AND_LAST_FRAME: No sequential usage, functionnal is same as associated interfaces in no sequential mode
(++) FMPI2C_FIRST_FRAME: Sequential usage, this option allow to manage a sequence with start condition, address
and data to transfer without a final stop condition
(++) FMPI2C_FIRST_AND_NEXT_FRAME: Sequential usage (Master only), this option allow to manage a sequence with start condition, address
and data to transfer without a final stop condition, an then permit a call the same master sequential interface
several times (like HAL_FMPI2C_Master_Sequential_Transmit_IT() then HAL_FMPI2C_Master_Sequential_Transmit_IT())
(++) FMPI2C_NEXT_FRAME: Sequential usage, this option allow to manage a sequence with a restart condition, address
and with new data to transfer if the direction change or manage only the new data to transfer
if no direction change and without a final stop condition in both cases
(++) FMPI2C_LAST_FRAME: Sequential usage, this option allow to manage a sequance with a restart condition, address
and with new data to transfer if the direction change or manage only the new data to transfer
if no direction change and with a final stop condition in both cases
(++) FMPI2C_LAST_FRAME_NO_STOP: Sequential usage (Master only), this option allow to manage a restart condition after several call of the same master sequential
interface several times (link with option FMPI2C_FIRST_AND_NEXT_FRAME).
Usage can, transfer several bytes one by one using HAL_FMPI2C_Master_Sequential_Transmit_IT(option FMPI2C_FIRST_AND_NEXT_FRAME then FMPI2C_NEXT_FRAME)
or HAL_FMPI2C_Master_Sequential_Receive_IT(option FMPI2C_FIRST_AND_NEXT_FRAME then FMPI2C_NEXT_FRAME).
Then usage of this option FMPI2C_LAST_FRAME_NO_STOP at the last Transmit or Receive sequence permit to call the oposite interface Receive or Transmit
without stopping the communication and so generate a restart condition.
