============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The PSSI HAL driver can be used as follows: + + (#) Declare a PSSI_HandleTypeDef handle structure, for example: + PSSI_HandleTypeDef hpssi; + + (#) Initialize the PSSI low level resources by implementing the @ref HAL_PSSI_MspInit() API: + (##) Enable the PSSIx interface clock + (##) PSSI pins configuration + (+++) Enable the clock for the PSSI GPIOs + (+++) Configure PSSI pins as alternate function open-drain + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the PSSIx interrupt priority + (+++) Enable the NVIC PSSI IRQ Channel + (##) DMA Configuration if you need to use DMA process + (+++) Declare DMA_HandleTypeDef handles structure for the transmit and receive + (+++) Enable the DMAx interface clock + (+++) Configure the DMA handle parameters + (+++) Configure the DMA Tx and Rx + (+++) Associate the initialized DMA handle to the hpssi DMA Tx and Rx handle + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on + the DMA Tx and Rx + + (#) Configure the Communication Bus Width, Control Signals, Input Polarity and Output Polarity + in the hpssi Init structure. + + (#) Initialize the PSSI registers by calling the @ref HAL_PSSI_Init(), configure also the low level Hardware + (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_PSSI_MspInit(&hpssi) API. + + + (#) For PSSI IO operations, two operation modes are available within this driver : + + *** Polling mode IO operation *** + ================================= + [..] + (+) Transmit an amount of data by byte in blocking mode using @ref HAL_PSSI_Transmit() + (+) Receive an amount of data by byte in blocking mode using @ref HAL_PSSI_Receive() + + *** DMA mode IO operation *** + ============================== + [..] + (+) Transmit an amount of data in non-blocking mode (DMA) using + @ref HAL_PSSI_Transmit_DMA() + (+) At transmission end of transfer, @ref HAL_PSSI_TxCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_TxCpltCallback() + (+) Receive an amount of data in non-blocking mode (DMA) using + @ref HAL_PSSI_Receive_DMA() + (+) At reception end of transfer, @ref HAL_PSSI_RxCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_RxCpltCallback() + (+) In case of transfer Error, @ref HAL_PSSI_ErrorCallback() function is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_ErrorCallback() + (+) Abort a PSSI process communication with Interrupt using @ref HAL_PSSI_Abort_IT() + (+) End of abort process, @ref HAL_PSSI_AbortCpltCallback() is executed and user can + add his own code by customization of function pointer @ref HAL_PSSI_AbortCpltCallback() + + *** PSSI HAL driver macros list *** + ================================== + [..] + Below the list of most used macros in PSSI HAL driver. + + (+) @ref HAL_PSSI_ENABLE : Enable the PSSI peripheral + (+) @ref HAL_PSSI_DISABLE : Disable the PSSI peripheral + (+) @ref HAL_PSSI_GET_FLAG : Check whether the specified PSSI flag is set or not + (+) @ref HAL_PSSI_CLEAR_FLAG : Clear the specified PSSI pending flag + (+) @ref HAL_PSSI_ENABLE_IT : Enable the specified PSSI interrupt + (+) @ref HAL_PSSI_DISABLE_IT : Disable the specified PSSI interrupt + + *** Callback registration *** + ============================================= + Use Functions @ref HAL_PSSI_RegisterCallback() or @ref HAL_PSSI_RegisterAddrCallback() + to register an interrupt callback. + + Function @ref HAL_PSSI_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : callback for transmission end of transfer. + (+) RxCpltCallback : callback for reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + + Use function @ref HAL_PSSI_UnRegisterCallback to reset a callback to the default + weak function. + @ref HAL_PSSI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : callback for transmission end of transfer. + (+) RxCpltCallback : callback for reception end of transfer. + (+) ErrorCallback : callback for error detection. + (+) AbortCpltCallback : callback for abort completion process. + (+) MspInitCallback : callback for Msp Init. + (+) MspDeInitCallback : callback for Msp DeInit. + + + By default, after the @ref HAL_PSSI_Init() and when the state is @ref HAL_PSSI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples @ref HAL_PSSI_TxCpltCallback(), @ref HAL_PSSI_RxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in @ref HAL_PSSI_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in @ref HAL_PSSI_STATE_READY or @ref HAL_PSSI_STATE_RESET state, + thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. + Then, the user first registers the MspInit/MspDeInit user callbacks + using @ref HAL_PSSI_RegisterCallback() before calling @ref HAL_PSSI_DeInit() + or @ref HAL_PSSI_Init() function. + + + [..] + (@) You can refer to the PSSI HAL
