26 ##### How to use this driver #####
27 ==============================================================================
28 [..]
29 The SMARTCARD HAL driver can be used as follows:
30
31 (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard).
32 (#) Associate a USART to the SMARTCARD handle hsmartcard.
33 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
34 (++) Enable the USARTx interface clock.
35 (++) USART pins configuration:
36 (+++) Enable the clock for the USART GPIOs.
37 (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
38 (++) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
39 and HAL_SMARTCARD_Receive_IT() APIs):
40 (+++) Configure the USARTx interrupt priority.
41 (+++) Enable the NVIC USART IRQ handle.
42 (++) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
43 and HAL_SMARTCARD_Receive_DMA() APIs):
44 (+++) Declare a DMA handle structure for the Tx/Rx channel.
45 (+++) Enable the DMAx interface clock.
46 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
47 (+++) Configure the DMA Tx/Rx channel.
48 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
49 (+++) Configure the priority and enable the NVIC for the transfer complete
50 interrupt on the DMA Tx/Rx channel.
51
52 (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly,
53 the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission
54 error enabling or disabling in the hsmartcard handle Init structure.
55
56 (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...)
57 in the hsmartcard handle AdvancedInit structure.
58
59 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
60 (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
61 by calling the customized HAL_SMARTCARD_MspInit() API.
62 [..]
63 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
64 RXNE interrupt and Error Interrupts) will be managed using the macros
65 __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
66
67 [..]
68 [..] Three operation modes are available within this driver :
69
70 *** Polling mode IO operation ***
71 =================================
72 [..]
73 (+) Send an amount of data in blocking mode using HAL_SMARTCARD_Transmit()

82 (+) Receive an amount of data in non-blocking mode using HAL_SMARTCARD_Receive_IT()
83 (+) At reception end of transfer HAL_SMARTCARD_RxCpltCallback() is executed and user can

87
88 *** DMA mode IO operation ***
89 ==============================
90 [..]
91 (+) Send an amount of data in non-blocking mode (DMA) using HAL_SMARTCARD_Transmit_DMA()

97 (+) In case of transfer Error, HAL_SMARTCARD_ErrorCallback() function is executed and user can
98 add his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback()
99
100 *** SMARTCARD HAL driver macros list ***
101 ========================================
102 [..]
103 Below the list of most used macros in SMARTCARD HAL driver.
104
105 (+) __HAL_SMARTCARD_GET_FLAG : Check whether or not the specified SMARTCARD flag is set
106 (+) __HAL_SMARTCARD_CLEAR_FLAG : Clear the specified SMARTCARD pending flag
107 (+) __HAL_SMARTCARD_ENABLE_IT: Enable the specified SMARTCARD interrupt
108 (+) __HAL_SMARTCARD_DISABLE_IT: Disable the specified SMARTCARD interrupt
109 (+) __HAL_SMARTCARD_GET_IT_SOURCE: Check whether or not the specified SMARTCARD interrupt is enabled
110
111 [..]
112 (@) You can refer to the SMARTCARD HAL driver header file for more useful macros
113
114 ##### Callback registration #####
115 ==================================
116
117 [..]
118 The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS when set to 1
119 allows the user to configure dynamically the driver callbacks.
120
121 [..]
122 Use Function HAL_SMARTCARD_RegisterCallback() to register a user callback.
123 Function HAL_SMARTCARD_RegisterCallback() allows to register following callbacks:
124 (+) TxCpltCallback : Tx Complete Callback.
125 (+) RxCpltCallback : Rx Complete Callback.
126 (+) ErrorCallback : Error Callback.
127 (+) AbortCpltCallback : Abort Complete Callback.
128 (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
129 (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
130 (+) RxFifoFullCallback : Rx Fifo Full Callback.
131 (+) TxFifoEmptyCallback : Tx Fifo Empty Callback.
132 (+) MspInitCallback : SMARTCARD MspInit.
133 (+) MspDeInitCallback : SMARTCARD MspDeInit.
134 This function takes as parameters the HAL peripheral handle, the Callback ID
135 and a pointer to the user callback function.
136
137 [..]
138 Use function HAL_SMARTCARD_UnRegisterCallback() to reset a callback to the default
139 weak (surcharged) function.
140 HAL_SMARTCARD_UnRegisterCallback() takes as parameters the HAL peripheral handle,
141 and the Callback ID.
142 This function allows to reset following callbacks:
143 (+) TxCpltCallback : Tx Complete Callback.
144 (+) RxCpltCallback : Rx Complete Callback.
145 (+) ErrorCallback : Error Callback.
146 (+) AbortCpltCallback : Abort Complete Callback.
147 (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback.
148 (+) AbortReceiveCpltCallback : Abort Receive Complete Callback.
149 (+) RxFifoFullCallback : Rx Fifo Full Callback.
150 (+) TxFifoEmptyCallback : Tx Fifo Empty Callback.
151 (+) MspInitCallback : SMARTCARD MspInit.
152 (+) MspDeInitCallback : SMARTCARD MspDeInit.
153
154 [..]
155 By default, after the HAL_SMARTCARD_Init() and when the state is HAL_SMARTCARD_STATE_RESET
156 all callbacks are set to the corresponding weak (surcharged) functions:
157 examples HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback().
158 Exception done for MspInit and MspDeInit functions that are respectively
159 reset to the legacy weak (surcharged) functions in the HAL_SMARTCARD_Init()
160 and HAL_SMARTCARD_DeInit() only when these callbacks are null (not registered beforehand).
161 If not, MspInit or MspDeInit are not null, the HAL_SMARTCARD_Init() and HAL_SMARTCARD_DeInit()
162 keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
163
164 [..]
165 Callbacks can be registered/unregistered in HAL_SMARTCARD_STATE_READY state only.
166 Exception done MspInit/MspDeInit that can be registered/unregistered
167 in HAL_SMARTCARD_STATE_READY or HAL_SMARTCARD_STATE_RESET state, thus registered (user)
168 MspInit/DeInit callbacks can be used during the Init/DeInit.
169 In that case first register the MspInit/MspDeInit user callbacks
170 using HAL_SMARTCARD_RegisterCallback() before calling HAL_SMARTCARD_DeInit()
171 or HAL_SMARTCARD_Init() function.
172
173 [..]
174 When The compilation define USE_HAL_SMARTCARD_REGISTER_CALLBACKS is set to 0 or
175 not defined, the callback registration feature is not available
176 and weak (surcharged) callbacks are used.

715 ##### IO operation functions #####
716 ==============================================================================
717 [..]
718 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
719
720 [..]
721 Smartcard is a single wire half duplex communication protocol.
722 The Smartcard interface is designed to support asynchronous protocol Smartcards as
723 defined in the ISO 7816-3 standard. The USART should be configured as:
724 (+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
725 (+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
726
727 [..]
728 (#) There are two modes of transfer:
729 (##) Blocking mode: The communication is performed in polling mode.
730 The HAL status of all data processing is returned by the same function
731 after finishing transfer.
732 (##) Non-Blocking mode: The communication is performed using Interrupts
733 or DMA, the relevant API's return the HAL status.
734 The end of the data processing will be indicated through the
735 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
736 using DMA mode.
737 (##) The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
738 will be executed respectively at the end of the Transmit or Receive process
739 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication
740 error is detected.
741
742 (#) Blocking mode APIs are :
743 (##) HAL_SMARTCARD_Transmit()
744 (##) HAL_SMARTCARD_Receive()
745
746 (#) Non Blocking mode APIs with Interrupt are :
747 (##) HAL_SMARTCARD_Transmit_IT()
748 (##) HAL_SMARTCARD_Receive_IT()
749 (##) HAL_SMARTCARD_IRQHandler()
750
751 (#) Non Blocking mode functions with DMA are :
752 (##) HAL_SMARTCARD_Transmit_DMA()
753 (##) HAL_SMARTCARD_Receive_DMA()
754
755 (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
756 (##) HAL_SMARTCARD_TxCpltCallback()
757 (##) HAL_SMARTCARD_RxCpltCallback()
758 (##) HAL_SMARTCARD_ErrorCallback()
759
760 [..]
761 (#) Non-Blocking mode transfers could be aborted using Abort API's :
762 (##) HAL_SMARTCARD_Abort()
763 (##) HAL_SMARTCARD_AbortTransmit()
764 (##) HAL_SMARTCARD_AbortReceive()
765 (##) HAL_SMARTCARD_Abort_IT()
766 (##) HAL_SMARTCARD_AbortTransmit_IT()
767 (##) HAL_SMARTCARD_AbortReceive_IT()
768
769 (#) For Abort services based on interrupts (HAL_SMARTCARD_Abortxxx_IT),
770 a set of Abort Complete Callbacks are provided:
771 (##) HAL_SMARTCARD_AbortCpltCallback()
772 (##) HAL_SMARTCARD_AbortTransmitCpltCallback()
773 (##) HAL_SMARTCARD_AbortReceiveCpltCallback()
774
775 (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
776 Errors are handled as follows :
777 (##) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
778 to be evaluated by user : this concerns Frame Error,
779 Parity Error or Noise Error in Interrupt mode reception .
780 Received character is then retrieved and stored in Rx buffer,
781 Error code is set to allow user to identify error type,
782 and HAL_SMARTCARD_ErrorCallback() user callback is executed. Transfer is kept ongoing on SMARTCARD side.
783 If user wants to abort it, Abort services should be called by user.
784 (##) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
785 This concerns Frame Error in Interrupt mode transmission, Overrun Error in Interrupt
786 mode reception and all errors in DMA mode.
787 Error code is set to allow user to identify error type,
788 and HAL_SMARTCARD_ErrorCallback() user callback is executed.
