==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) Initialize the FDCAN peripheral using HAL_FDCAN_Init function.
(#) If needed , configure the reception filters and optional features using
the following configuration functions:
(++) HAL_FDCAN_ConfigClockCalibration
(++) HAL_FDCAN_ConfigFilter
(++) HAL_FDCAN_ConfigGlobalFilter
(++) HAL_FDCAN_ConfigExtendedIdMask
(++) HAL_FDCAN_ConfigRxFifoOverwrite
(++) HAL_FDCAN_ConfigFifoWatermark
(++) HAL_FDCAN_ConfigRamWatchdog
(++) HAL_FDCAN_ConfigTimestampCounter
(++) HAL_FDCAN_EnableTimestampCounter
(++) HAL_FDCAN_DisableTimestampCounter
(++) HAL_FDCAN_ConfigTimeoutCounter
(++) HAL_FDCAN_EnableTimeoutCounter
(++) HAL_FDCAN_DisableTimeoutCounter
(++) HAL_FDCAN_ConfigTxDelayCompensation
(++) HAL_FDCAN_EnableTxDelayCompensation
(++) HAL_FDCAN_DisableTxDelayCompensation
(++) HAL_FDCAN_EnableISOMode
(++) HAL_FDCAN_DisableISOMode
(++) HAL_FDCAN_EnableEdgeFiltering
(++) HAL_FDCAN_DisableEdgeFiltering
(++) HAL_FDCAN_TT_ConfigOperation
(++) HAL_FDCAN_TT_ConfigReferenceMessage
(++) HAL_FDCAN_TT_ConfigTrigger
(#) Start the FDCAN module using HAL_FDCAN_Start function. At this level
the node is active on the bus: it can send and receive messages.
(#) The following Tx control functions can only be called when the FDCAN
module is started:
(++) HAL_FDCAN_AddMessageToTxFifoQ
(++) HAL_FDCAN_EnableTxBufferRequest
(++) HAL_FDCAN_AbortTxRequest
(#) After having submitted a Tx request in Tx Fifo or Queue, it is possible to
get Tx buffer location used to place the Tx request thanks to
HAL_FDCAN_GetLatestTxFifoQRequestBuffer API.
It is then possible to abort later on the corresponding Tx Request using
HAL_FDCAN_AbortTxRequest API.
(#) When a message is received into the FDCAN message RAM, it can be
retrieved using the HAL_FDCAN_GetRxMessage function.
(#) Calling the HAL_FDCAN_Stop function stops the FDCAN module by entering
it to initialization mode and re-enabling access to configuration
registers through the configuration functions listed here above.
(#) All other control functions can be called any time after initialization
phase, no matter if the FDCAN module is started or stoped.
*** Polling mode operation ***
==============================
[..]
(#) Reception and transmission states can be monitored via the following
functions:
(++) HAL_FDCAN_IsRxBufferMessageAvailable
(++) HAL_FDCAN_IsTxBufferMessagePending
(++) HAL_FDCAN_GetRxFifoFillLevel
(++) HAL_FDCAN_GetTxFifoFreeLevel
*** Interrupt mode operation ***
================================
[..]
(#) There are two interrupt lines: line 0 and 1.
By default, all interrupts are assigned to line 0. Interrupt lines
can be configured using HAL_FDCAN_ConfigInterruptLines function.
(#) Notifications are activated using HAL_FDCAN_ActivateNotification
function. Then, the process can be controlled through one of the
available user callbacks: HAL_FDCAN_xxxCallback.
*** Callback registration ***
=============================================
The compilation define USE_HAL_FDCAN_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
Use Function @ref HAL_FDCAN_RegisterCallback() or HAL_FDCAN_RegisterXXXCallback()
to register an interrupt callback.
Function @ref HAL_FDCAN_RegisterCallback() allows to register following callbacks:
(+) TxFifoEmptyCallback : Tx Fifo Empty Callback.
(+) RxBufferNewMessageCallback : Rx Buffer New Message Callback.
(+) HighPriorityMessageCallback : High Priority Message Callback.
(+) TimestampWraparoundCallback : Timestamp Wraparound Callback.
(+) TimeoutOccurredCallback : Timeout Occurred Callback.
(+) ErrorCallback : Error Callback.
(+) MspInitCallback : FDCAN MspInit.
(+) MspDeInitCallback : FDCAN MspDeInit.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
For specific callbacks ClockCalibrationCallback, TxEventFifoCallback, RxFifo0Callback, RxFifo1Callback,
TxBufferCompleteCallback, TxBufferAbortCallback, ErrorStatusCallback, TT_ScheduleSyncCallback, TT_TimeMarkCallback,
TT_StopWatchCallback and TT_GlobalTimeCallback, use dedicated register callbacks :
respectively @ref HAL_FDCAN_RegisterClockCalibrationCallback(), @ref HAL_FDCAN_RegisterTxEventFifoCallback(),
@ref HAL_FDCAN_RegisterRxFifo0Callback(), @ref HAL_FDCAN_RegisterRxFifo1Callback(),
@ref HAL_FDCAN_RegisterTxBufferCompleCallback(), @ref HAL_FDCAN_RegisterTxBufferAbortCallback(),
@ref HAL_FDCAN_RegisterErrorStatusCallback(), @ref HAL_FDCAN_TT_RegisterScheduleSyncCallback(),
@ref HAL_FDCAN_TT_RegisterTimeMarkCallback(), @ref HAL_FDCAN_TT_RegisterStopWatchCallback() and
@ref HAL_FDCAN_TT_RegisterGlobalTimeCallback().
Use function @ref HAL_FDCAN_UnRegisterCallback() to reset a callback to the default
weak function.
@ref HAL_FDCAN_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) TxFifoEmptyCallback : Tx Fifo Empty Callback.
(+) RxBufferNewMessageCallback : Rx Buffer New Message Callback.
(+) HighPriorityMessageCallback : High Priority Message Callback.
(+) TimestampWraparoundCallback : Timestamp Wraparound Callback.
(+) TimeoutOccurredCallback : Timeout Occurred Callback.
(+) ErrorCallback : Error Callback.
(+) MspInitCallback : FDCAN MspInit.
(+) MspDeInitCallback : FDCAN MspDeInit.
For specific callbacks ClockCalibrationCallback, TxEventFifoCallback, RxFifo0Callback,
RxFifo1Callback, TxBufferCompleteCallback, TxBufferAbortCallback, TT_ScheduleSyncCallback,
TT_TimeMarkCallback, TT_StopWatchCallback and TT_GlobalTimeCallback, use dedicated
register callbacks : respectively @ref HAL_FDCAN_UnRegisterClockCalibrationCallback(),
@ref HAL_FDCAN_UnRegisterTxEventFifoCallback(), @ref HAL_FDCAN_UnRegisterRxFifo0Callback(),
@ref HAL_FDCAN_UnRegisterRxFifo1Callback(), @ref HAL_FDCAN_UnRegisterTxBufferCompleCallback(),
@ref HAL_FDCAN_UnRegisterTxBufferAbortCallback(), @ref HAL_FDCAN_UnRegisterErrorStatusCallback(),
@ref HAL_FDCAN_TT_UnRegisterScheduleSyncCallback(), @ref HAL_FDCAN_TT_UnRegisterTimeMarkCallback(),
@ref HAL_FDCAN_TT_UnRegisterStopWatchCallback() and @ref HAL_FDCAN_TT_UnRegisterGlobalTimeCallback().
By default, after the @ref HAL_FDCAN_Init() and when the state is HAL_FDCAN_STATE_RESET,
all callbacks are set to the corresponding weak functions:
examples @ref HAL_FDCAN_ErrorCallback().
Exception done for MspInit and MspDeInit functions that are
reset to the legacy weak function in the @ref HAL_FDCAN_Init()/ @ref HAL_FDCAN_DeInit() only when
these callbacks are null (not registered beforehand).
if not, MspInit or MspDeInit are not null, the @ref HAL_FDCAN_Init()/ @ref HAL_FDCAN_DeInit()
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
Callbacks can be registered/unregistered in HAL_FDCAN_STATE_READY state only.
Exception done MspInit/MspDeInit that can be registered/unregistered
in HAL_FDCAN_STATE_READY or HAL_FDCAN_STATE_RESET state,
thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
In that case first register the MspInit/MspDeInit user callbacks
using @ref HAL_FDCAN_RegisterCallback() before calling @ref HAL_FDCAN_DeInit()
or @ref HAL_FDCAN_Init() function.
When The compilation define USE_HAL_FDCAN_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registration feature is not available and all callbacks
are set to the corresponding weak functions.
