##### 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()
|
|
|
|
(#) For FMPI2C IO and IO MEM operations, three mode of operations are available within this driver :
|
|
|

This subsection provides a set of functions allowing to manage the FMPI2C data
|
|
transfers.
|
|
|
|
(#) There is two mode of transfer:
|
|
(++) Blocking mode : The communication is performed in the polling mode.
|
|
The status of all data processing is returned by the same function
|
|
after finishing transfer.
|
|
(++) No-Blocking mode : The communication is performed using Interrupts
|
|
or DMA. These functions return the status of the transfer startup.
|
|
The end of the data processing will be indicated through the
|
|
dedicated FMPI2C IRQ when using Interrupt mode or the DMA IRQ when
|
|
using DMA mode.
|
|
|
|
(#) Blocking mode functions are :
|
|
(++) HAL_FMPI2C_Master_Transmit()
|
|
(++) HAL_FMPI2C_Master_Receive()
|
|
(++) HAL_FMPI2C_Slave_Transmit()
|
|
(++) HAL_FMPI2C_Slave_Receive()
|
|
(++) HAL_FMPI2C_Mem_Write()
|
|
(++) HAL_FMPI2C_Mem_Read()
|
|
(++) HAL_FMPI2C_IsDeviceReady()
|
|
|
|
(#) No-Blocking mode functions with Interrupt are :
|
|
(++) HAL_FMPI2C_Master_Transmit_IT()
|
|
(++) HAL_FMPI2C_Master_Receive_IT()
|
|
(++) HAL_FMPI2C_Slave_Transmit_IT()
|
|
(++) HAL_FMPI2C_Slave_Receive_IT()
|
|
(++) HAL_FMPI2C_Mem_Write_IT()
|
|
(++) HAL_FMPI2C_Mem_Read_IT()
|
|
|
|
(#) No-Blocking mode functions with DMA are :
|
|
(++) HAL_FMPI2C_Master_Transmit_DMA()
|
|
(++) HAL_FMPI2C_Master_Receive_DMA()
|
|
(++) HAL_FMPI2C_Slave_Transmit_DMA()
|
|
(++) HAL_FMPI2C_Slave_Receive_DMA()
|
|
(++) HAL_FMPI2C_Mem_Write_DMA()
|
|
(++) HAL_FMPI2C_Mem_Read_DMA()
|
|
|
|
(#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
|
|
(++) HAL_FMPI2C_MemTxCpltCallback()
|
|
(++) HAL_FMPI2C_MemRxCpltCallback()
|
|
(++) HAL_FMPI2C_MasterTxCpltCallback()
|
|
(++) HAL_FMPI2C_MasterRxCpltCallback()
|

(++) HAL_FMPI2C_SlaveTxCpltCallback()
