##### How to use this driver #####
==============================================================================
[..]
The ETH HAL driver can be used as follows:
(#)Declare a ETH_HandleTypeDef handle structure, for example:
ETH_HandleTypeDef heth;
(#)Fill parameters of Init structure in heth handle
(#)Call HAL_ETH_Init() API to initialize the Ethernet peripheral (MAC, DMA, ...)
(#)Initialize the ETH low level resources through the HAL_ETH_MspInit() API:
(##) Enable the Ethernet interface clock using
(+++) __HAL_RCC_ETH1MAC_CLK_ENABLE()
(+++) __HAL_RCC_ETH1TX_CLK_ENABLE()
(+++) __HAL_RCC_ETH1RX_CLK_ENABLE()
(##) Initialize the related GPIO clocks
(##) Configure Ethernet pinout
(##) Configure Ethernet NVIC interrupt (in Interrupt mode)
(#) Ethernet data reception is asynchronous, so call the following API
to start the listening mode:
(##) HAL_ETH_Start():
This API starts the MAC and DMA transmission and reception process,
without enabling end of transfer interrupts, in this mode user
has to poll for data reception by calling HAL_ETH_ReadData()
(##) HAL_ETH_Start_IT():
This API starts the MAC and DMA transmission and reception process,
end of transfer interrupts are enabled in this mode,
HAL_ETH_RxCpltCallback() will be executed when an Ethernet packet is received
(#) When data is received user can call the following API to get received data:
(##) HAL_ETH_ReadData(): Read a received packet
(#) For transmission path, two APIs are available:
(##) HAL_ETH_Transmit(): Transmit an ETH frame in blocking mode
(##) HAL_ETH_Transmit_IT(): Transmit an ETH frame in interrupt mode,
HAL_ETH_TxCpltCallback() will be executed when end of transfer occur
(#) Communication with an external PHY device:
(##) HAL_ETH_ReadPHYRegister(): Read a register from an external PHY
(##) HAL_ETH_WritePHYRegister(): Write data to an external RHY register
(#) Configure the Ethernet MAC after ETH peripheral initialization
(##) HAL_ETH_GetMACConfig(): Get MAC actual configuration into ETH_MACConfigTypeDef
(##) HAL_ETH_SetMACConfig(): Set MAC configuration based on ETH_MACConfigTypeDef
(#) Configure the Ethernet DMA after ETH peripheral initialization
(##) HAL_ETH_GetDMAConfig(): Get DMA actual configuration into ETH_DMAConfigTypeDef
(##) HAL_ETH_SetDMAConfig(): Set DMA configuration based on ETH_DMAConfigTypeDef
(#) Configure the Ethernet PTP after ETH peripheral initialization
(##) Define HAL_ETH_USE_PTP to use PTP APIs.
(##) HAL_ETH_PTP_GetConfig(): Get PTP actual configuration into ETH_PTP_ConfigTypeDef
(##) HAL_ETH_PTP_SetConfig(): Set PTP configuration based on ETH_PTP_ConfigTypeDef
(##) HAL_ETH_PTP_GetTime(): Get Seconds and Nanoseconds for the Ethernet PTP registers
(##) HAL_ETH_PTP_SetTime(): Set Seconds and Nanoseconds for the Ethernet PTP registers
(##) HAL_ETH_PTP_AddTimeOffset(): Add Seconds and Nanoseconds offset for the Ethernet PTP registers
(##) HAL_ETH_PTP_InsertTxTimestamp(): Insert Timestamp in transmission
(##) HAL_ETH_PTP_GetTxTimestamp(): Get transmission timestamp
(##) HAL_ETH_PTP_GetRxTimestamp(): Get reception timestamp
-@- The ARP offload feature is not supported in this driver.
-@- The PTP offload feature is not supported in this driver.
*** Callback registration ***
=============================================
The compilation define USE_HAL_ETH_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
Use Function HAL_ETH_RegisterCallback() to register an interrupt callback.
Function HAL_ETH_RegisterCallback() allows to register following callbacks:
(+) TxCpltCallback : Tx Complete Callback.
(+) RxCpltCallback : Rx Complete Callback.
(+) ErrorCallback : Error Callback.
(+) PMTCallback : Power Management Callback
(+) EEECallback : EEE 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.
For specific callbacks RxAllocateCallback use dedicated register callbacks:
respectively HAL_ETH_RegisterRxAllocateCallback().
For specific callbacks RxLinkCallback use dedicated register callbacks:
respectively HAL_ETH_RegisterRxLinkCallback().
For specific callbacks TxFreeCallback use dedicated register callbacks:
respectively HAL_ETH_RegisterTxFreeCallback().
For specific callbacks TxPtpCallback use dedicated register callbacks:
respectively HAL_ETH_RegisterTxPtpCallback().
Use function HAL_ETH_UnRegisterCallback() to reset a callback to the default
weak function.
HAL_ETH_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) TxCpltCallback : Tx Complete Callback.
(+) RxCpltCallback : Rx Complete Callback.
(+) ErrorCallback : Error Callback.
(+) PMTCallback : Power Management Callback
(+) EEECallback : EEE Callback.
(+) WakeUpCallback : Wake UP Callback
(+) MspInitCallback : MspInit Callback.
(+) MspDeInitCallback: MspDeInit Callback.
For specific callbacks RxAllocateCallback use dedicated unregister callbacks:
respectively HAL_ETH_UnRegisterRxAllocateCallback().
For specific callbacks RxLinkCallback use dedicated unregister callbacks:
respectively HAL_ETH_UnRegisterRxLinkCallback().
For specific callbacks TxFreeCallback use dedicated unregister callbacks:
respectively HAL_ETH_UnRegisterTxFreeCallback().
For specific callbacks TxPtpCallback use dedicated unregister callbacks:
respectively HAL_ETH_UnRegisterTxPtpCallback().
By default, after the HAL_ETH_Init and when the state is HAL_ETH_STATE_RESET
all callbacks are set to the corresponding weak functions:
examples HAL_ETH_TxCpltCallback(), HAL_ETH_RxCpltCallback().
Exception done for MspInit and MspDeInit functions that are
reset to the legacy weak function in the HAL_ETH_Init/ HAL_ETH_DeInit only when
these callbacks are null (not registered beforehand).
if not, MspInit or MspDeInit are not null, the HAL_ETH_Init/ HAL_ETH_DeInit
keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
Callbacks can be registered/unregistered in HAL_ETH_STATE_READY state only.
Exception done MspInit/MspDeInit that can be registered/unregistered
in HAL_ETH_STATE_READY or HAL_ETH_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 HAL_ETH_RegisterCallback() before calling HAL_ETH_DeInit
or HAL_ETH_Init function.
When The compilation define USE_HAL_ETH_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.
