##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
The MDIOS HAL driver can be used as follows:
|
||||
|
||||
(#) Declare a MDIOS_HandleTypeDef handle structure.
|
||||
|
||||
(#) Initialize the MDIOS low level resources by implementing the HAL_MDIOS_MspInit() API:
|
||||
(##) Enable the MDIOS interface clock.
|
||||
(##) MDIOS pins configuration:
|
||||
(+++) Enable clocks for the MDIOS GPIOs.
|
||||
(+++) Configure the MDIOS pins as alternate function.
|
||||
(##) NVIC configuration if you need to use interrupt process:
|
||||
(+++) Configure the MDIOS interrupt priority.
|
||||
(+++) Enable the NVIC MDIOS IRQ handle.
|
||||
|
||||
(#) Program the Port Address and the Preamble Check in the Init structure.
|
||||
|
||||
(#) Initialize the MDIOS registers by calling the HAL_MDIOS_Init() API.
|
||||
|
||||
(#) Perform direct slave read/write operations using the following APIs:
|
||||
(##) Read the value of a DINn register: HAL_MDIOS_ReadReg()
|
||||
(##) Write a value to a DOUTn register: HAL_MDIOS_WriteReg()
|
||||
|
||||
(#) Get the Master read/write operations flags using the following APIs:
|
||||
(##) Bit map of DOUTn registers read by Master: HAL_MDIOS_GetReadRegAddress()
|
||||
(##) Bit map of DINn registers written by Master : HAL_MDIOS_GetWrittenRegAddress()
|
||||
|
||||
(#) Clear the read/write flags using the following APIs:
|
||||
(##) Clear read flags of a set of registers: HAL_MDIOS_ClearReadRegAddress()
|
||||
(##) Clear write flags of a set of registers: HAL_MDIOS_ClearWriteRegAddress()
|
||||
|
||||
(#) Enable interrupts on events using HAL_MDIOS_EnableEvents(), when called
|
||||
the MDIOS will generate an interrupt in the following cases:
|
||||
(##) a DINn register written by the Master
|
||||
(##) a DOUTn register read by the Master
|
||||
(##) an error occur
|
||||
|
||||
-@@- A callback is executed for each genereted interrupt, so the driver provides the following
|
||||
HAL_MDIOS_WriteCpltCallback(), HAL_MDIOS_ReadCpltCallback() and HAL_MDIOS_ErrorCallback()
|
||||
-@@- HAL_MDIOS_IRQHandler() must be called from the MDIOS IRQ Handler, to handle the interrupt
|
||||
and execute the previous callbacks
|
||||
|
||||
(#) Reset the MDIOS peripheral and all related resources by calling the HAL_MDIOS_DeInit() API.
|
||||
(##) HAL_MDIOS_MspDeInit() must be implemented to reset low level resources
|
||||
(GPIO, Clocks, NVIC configuration ...)
|
||||
|
||||
*** Callback registration ***
|
||||
=============================================
|
||||
|
||||
The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS when set to 1
|
||||
allows the user to configure dynamically the driver callbacks.
|
||||
Use Function @ref HAL_MDIOS_RegisterCallback() to register an interrupt callback.
|
||||
|
||||
Function @ref HAL_MDIOS_RegisterCallback() allows to register following callbacks:
|
||||
(+) WriteCpltCallback : Write Complete Callback.
|
||||
(+) ReadCpltCallback : Read Complete Callback.
|
||||
(+) ErrorCallback : Error Callback.
|
||||
(+) WakeUpCallback : Wake UP Callback
|
||||
(+) MspInitCallback : MspInit Callback.
|
||||
(+) MspDeInitCallback : MspDeInit Callback.
|
||||
|
||||
This function takes as parameters the HAL peripheral handle, the Callback ID
|
||||
and a pointer to the user callback function.
|
||||
|
||||
Use function @ref HAL_MDIOS_UnRegisterCallback() to reset a callback to the default
|
||||
weak function.
|
||||
@ref HAL_MDIOS_UnRegisterCallback takes as parameters the HAL peripheral handle,
|
||||
and the Callback ID.
|
||||
This function allows to reset following callbacks:
|
||||
(+) WriteCpltCallback : Write Complete Callback.
|
||||
(+) ReadCpltCallback : Read Complete Callback.
|
||||
(+) ErrorCallback : Error Callback.
|
||||
(+) WakeUpCallback : Wake UP Callback
|
||||
(+) MspInitCallback : MspInit Callback.
|
||||
(+) MspDeInitCallback : MspDeInit Callback.
|
||||
|
||||
By default, after the HAL_MDIOS_Init and when the state is HAL_MDIOS_STATE_RESET
|
||||
all callbacks are set to the corresponding weak functions:
|
||||
examples @ref HAL_MDIOS_WriteCpltCallback(), @ref HAL_MDIOS_ReadCpltCallback().
|
||||
Exception done for MspInit and MspDeInit functions that are
|
||||
reset to the legacy weak function in the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit only when
|
||||
these callbacks are null (not registered beforehand).
|
||||
if not, MspInit or MspDeInit are not null, the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit
|
||||
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
|
||||
|
||||
Callbacks can be registered/unregistered in HAL_MDIOS_STATE_READY state only.
|
||||
Exception done MspInit/MspDeInit that can be registered/unregistered
|
||||
in HAL_MDIOS_STATE_READY or HAL_MDIOS_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_MDIOS_RegisterCallback() before calling @ref HAL_MDIOS_DeInit
|
||||
or HAL_MDIOS_Init function.
|
||||
|
||||
When The compilation define USE_HAL_MDIOS_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.

values of one of the DINn/DOUTn registers:

(+) Read the value of a DINn register: HAL_MDIOS_ReadReg()

read or written by the Master:

(+) DOUTn registers read by Master: HAL_MDIOS_GetReadRegAddress()
|

(+) DINn registers written by Master : HAL_MDIOS_GetWrittenRegAddress()
|

(#) APIs that Clear the read/write flags:
