25 ##### How to use this driver #####
26 ==============================================================================
27 [..]
28 The PSSI HAL driver can be used as follows:
29
30 (#) Declare a PSSI_HandleTypeDef handle structure, for example:
31 PSSI_HandleTypeDef hpssi;
32
33 (#) Initialize the PSSI low level resources by implementing the @ref HAL_PSSI_MspInit() API:
34 (##) Enable the PSSIx interface clock
35 (##) PSSI pins configuration
36 (+++) Enable the clock for the PSSI GPIOs
37 (+++) Configure PSSI pins as alternate function open-drain
38 (##) NVIC configuration if you need to use interrupt process
39 (+++) Configure the PSSIx interrupt priority
40 (+++) Enable the NVIC PSSI IRQ Channel
41 (##) DMA Configuration if you need to use DMA process
42 (+++) Declare DMA_HandleTypeDef handles structure for the transmit and receive
43 (+++) Enable the DMAx interface clock
44 (+++) Configure the DMA handle parameters
45 (+++) Configure the DMA Tx and Rx
46 (+++) Associate the initialized DMA handle to the hpssi DMA Tx and Rx handle
47 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
48 the DMA Tx and Rx
49
50 (#) Configure the Communication Bus Width, Control Signals, Input Polarity and Output Polarity
51 in the hpssi Init structure.
52
53 (#) Initialize the PSSI registers by calling the @ref HAL_PSSI_Init(), configure also the low level Hardware
54 (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_PSSI_MspInit(&hpssi) API.
55
56
57 (#) For PSSI IO operations, two operation modes are available within this driver :
58
59 *** Polling mode IO operation ***
60 =================================
61 [..]
62 (+) Transmit an amount of data by byte in blocking mode using @ref HAL_PSSI_Transmit()
63 (+) Receive an amount of data by byte in blocking mode using @ref HAL_PSSI_Receive()
64
65 *** DMA mode IO operation ***
66 ==============================
67 [..]
68 (+) Transmit an amount of data in non-blocking mode (DMA) using
69 @ref HAL_PSSI_Transmit_DMA()
70 (+) At transmission end of transfer, @ref HAL_PSSI_TxCpltCallback() is executed and user can
71 add his own code by customization of function pointer @ref HAL_PSSI_TxCpltCallback()
72 (+) Receive an amount of data in non-blocking mode (DMA) using
73 @ref HAL_PSSI_Receive_DMA()
74 (+) At reception end of transfer, @ref HAL_PSSI_RxCpltCallback() is executed and user can
75 add his own code by customization of function pointer @ref HAL_PSSI_RxCpltCallback()
76 (+) In case of transfer Error, @ref HAL_PSSI_ErrorCallback() function is executed and user can
77 add his own code by customization of function pointer @ref HAL_PSSI_ErrorCallback()
78 (+) Abort a PSSI process communication with Interrupt using @ref HAL_PSSI_Abort_IT()
79 (+) End of abort process, @ref HAL_PSSI_AbortCpltCallback() is executed and user can
80 add his own code by customization of function pointer @ref HAL_PSSI_AbortCpltCallback()
81
82 *** PSSI HAL driver macros list ***
83 ==================================
84 [..]
85 Below the list of most used macros in PSSI HAL driver.
86
87 (+) @ref HAL_PSSI_ENABLE : Enable the PSSI peripheral
88 (+) @ref HAL_PSSI_DISABLE : Disable the PSSI peripheral
89 (+) @ref HAL_PSSI_GET_FLAG : Check whether the specified PSSI flag is set or not
90 (+) @ref HAL_PSSI_CLEAR_FLAG : Clear the specified PSSI pending flag
91 (+) @ref HAL_PSSI_ENABLE_IT : Enable the specified PSSI interrupt
92 (+) @ref HAL_PSSI_DISABLE_IT : Disable the specified PSSI interrupt
93
94 *** Callback registration ***
95 =============================================
96 Use Functions @ref HAL_PSSI_RegisterCallback() or @ref HAL_PSSI_RegisterAddrCallback()
97 to register an interrupt callback.
98
99 Function @ref HAL_PSSI_RegisterCallback() allows to register following callbacks:
100 (+) TxCpltCallback : callback for transmission end of transfer.
101 (+) RxCpltCallback : callback for reception end of transfer.
102 (+) ErrorCallback : callback for error detection.
103 (+) AbortCpltCallback : callback for abort completion process.
104 (+) MspInitCallback : callback for Msp Init.
105 (+) MspDeInitCallback : callback for Msp DeInit.
106 This function takes as parameters the HAL peripheral handle, the Callback ID
107 and a pointer to the user callback function.
108
109
110 Use function @ref HAL_PSSI_UnRegisterCallback to reset a callback to the default
111 weak function.
112 @ref HAL_PSSI_UnRegisterCallback takes as parameters the HAL peripheral handle,
113 and the Callback ID.
114 This function allows to reset following callbacks:
115 (+) TxCpltCallback : callback for transmission end of transfer.
116 (+) RxCpltCallback : callback for reception end of transfer.
117 (+) ErrorCallback : callback for error detection.
118 (+) AbortCpltCallback : callback for abort completion process.
119 (+) MspInitCallback : callback for Msp Init.
120 (+) MspDeInitCallback : callback for Msp DeInit.
121
122
123 By default, after the @ref HAL_PSSI_Init() and when the state is @ref HAL_PSSI_STATE_RESET
124 all callbacks are set to the corresponding weak functions:
125 examples @ref HAL_PSSI_TxCpltCallback(), @ref HAL_PSSI_RxCpltCallback().
126 Exception done for MspInit and MspDeInit functions that are
127 reset to the legacy weak functions in the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() only when
128 these callbacks are null (not registered beforehand).
129 If MspInit or MspDeInit are not null, the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit()
130 keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
131
132 Callbacks can be registered/unregistered in @ref HAL_PSSI_STATE_READY state only.
133 Exception done MspInit/MspDeInit functions that can be registered/unregistered
134 in @ref HAL_PSSI_STATE_READY or @ref HAL_PSSI_STATE_RESET state,
135 thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
136 Then, the user first registers the MspInit/MspDeInit user callbacks
137 using @ref HAL_PSSI_RegisterCallback() before calling @ref HAL_PSSI_DeInit()
138 or @ref HAL_PSSI_Init() function.

591 This subsection provides a set of functions allowing to manage the PSSI data
592 transfers.
593
594 (#) There are two modes of transfer:
595 (++) Blocking mode : The communication is performed in the polling mode.
596 The status of all data processing is returned by the same function
597 after finishing transfer.
598 (++) No-Blocking mode : The communication is performed using DMA.
599 These functions return the status of the transfer startup.
600 The end of the data processing will be indicated through the
601 dedicated the DMA IRQ .
602
603 (#) Blocking mode functions are :
604 (++) HAL_PSSI_Transmit()
605 (++) HAL_PSSI_Receive()
606
607 (#) No-Blocking mode functions with DMA are :
608 (++) HAL_PSSI_Transmit_DMA()
609 (++) HAL_PSSI_Receive_DMA()
610
611 (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
612 (++) HAL_PSSI_TxCpltCallback()
613 (++) HAL_PSSI_RxCpltCallback()
614 (++) HAL_PSSI_ErrorCallback()
615 (++) HAL_PSSI_AbortCpltCallback()
