##### How to use this driver #####
==============================================================================
[..]
The I2C HAL driver can be used as follows:

added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
(#) Declare a I2C_HandleTypeDef handle structure, for example:

(+++) Configure I2C pins as alternate function open-drain
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the I2Cx interrupt priority
(+++) Enable the NVIC I2C IRQ Channel

the DMA Tx or Rx channel
(#) 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 hi2c Init structure.
f3 hal and cmsis update
2018-03-02 03:34:09 +00:00
(#) Initialize the I2C registers by calling the HAL_I2C_Init(), configures also the low level Hardware

2017-01-05 14:45:54 +00:00
(GPIO, CLOCK, NVIC...etc) by calling the customized HAL_I2C_MspInit(&hi2c) API.
(#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
(#) For I2C IO and IO MEM operations, three operation modes are available within this driver :
*** Polling mode IO operation ***
=================================
[..]

when a direction change during transfer

(++) I2C_FIRST_AND_LAST_FRAME: No sequential usage, functionnal is same as associated interfaces in no sequential mode
(++) I2C_FIRST_FRAME: Sequential usage, this option allow to manage a sequence with start condition, address
and data to transfer without a final stop condition

2018-03-02 03:34:09 +00:00
(++) I2C_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_I2C_Master_Sequential_Transmit_IT() then HAL_I2C_Master_Sequential_Transmit_IT())

This subsection provides a set of functions allowing to manage the I2C data
added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
transfers.
(#) There are two modes of transfer:
f3 hal and cmsis update
2018-03-02 03:34:09 +00:00
(++) 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
added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
or DMA. These functions return the status of the transfer startup.
f3 hal and cmsis update
2018-03-02 03:34:09 +00:00
The end of the data processing will be indicated through the
dedicated I2C IRQ when using Interrupt mode or the DMA IRQ when
added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
using DMA mode.
(#) Blocking mode functions are :
(++) HAL_I2C_Master_Transmit()
(++) HAL_I2C_Master_Receive()
(++) HAL_I2C_Slave_Transmit()
(++) HAL_I2C_Slave_Receive()
(++) HAL_I2C_Mem_Write()
(++) HAL_I2C_Mem_Read()
(++) HAL_I2C_IsDeviceReady()

added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
(#) No-Blocking mode functions with Interrupt are :
(++) HAL_I2C_Master_Transmit_IT()
(++) HAL_I2C_Master_Receive_IT()
(++) HAL_I2C_Slave_Transmit_IT()
(++) HAL_I2C_Slave_Receive_IT()
(++) HAL_I2C_Mem_Write_IT()
(++) HAL_I2C_Mem_Read_IT()
(#) No-Blocking mode functions with DMA are :
(++) HAL_I2C_Master_Transmit_DMA()
(++) HAL_I2C_Master_Receive_DMA()
(++) HAL_I2C_Slave_Transmit_DMA()
(++) HAL_I2C_Slave_Receive_DMA()
(++) HAL_I2C_Mem_Write_DMA()
(++) HAL_I2C_Mem_Read_DMA()
(#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
(++) HAL_I2C_MemTxCpltCallback()
(++) HAL_I2C_MemRxCpltCallback()
(++) HAL_I2C_MasterTxCpltCallback()
(++) HAL_I2C_MasterRxCpltCallback()
(++) HAL_I2C_SlaveTxCpltCallback()
(++) HAL_I2C_SlaveRxCpltCallback()
(++) HAL_I2C_ErrorCallback()
