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

__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

============================================= + + 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

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

============================================================================== + ##### 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. + + @endverbatim + ****************************************************************************** + */ + +/* Includes

============================================================================== + ##### 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. + + @endverbatim + ****************************************************************************** + */ + +/* Includes
