16 ##### How to use this driver #####
|
|
|
17 ==============================================================================
|
|
|
18 [..]
|
|
|
19 The SMARTCARD HAL driver can be used as follows:
|
|
|
20
|
|
|
21 (#) Declare a SMARTCARD_HandleTypeDef handle structure.
|
|
|
22 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
|
|
|
23 (##) Enable the USARTx interface clock.
|
|
|
24 (##) SMARTCARD pins configuration:
|
|
|
25 (+++) Enable the clock for the SMARTCARD GPIOs.
|
|
|
26 (+++) Configure these SMARTCARD pins as alternate function pull-up.
|
|
|
27 (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT()
|
|
|
28 and HAL_SMARTCARD_Receive_IT() APIs):
|
|
|
29 (+++) Configure the USARTx interrupt priority.
|
|
|
30 (+++) Enable the NVIC USART IRQ handle.
|
|
|
31 (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
|
|
|
32 and HAL_SMARTCARD_Receive_DMA() APIs):
|
|
|
33 (+++) Declare a DMA handle structure for the Tx/Rx stream.
|
|
|
34 (+++) Enable the DMAx interface clock.
|
|
|
35 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
|
|
|
36 (+++) Configure the DMA Tx/Rx Stream.
|
|
|
37 (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle.
|
|
|
38 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
|
|
|
39
|
|
|
40 (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware
|
|
|
41 flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure.
|
|
|
42
|
|
|
43 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
|
|
|
44 (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
|
|
|
45 by calling the customized HAL_SMARTCARD_MspInit() API.
|
|
|
46 [..]
|
|
|
47 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,
|
|
|
48 RXNE interrupt and Error Interrupts) will be managed using the macros
|
|
|
49 __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
|
|
|
50
|
|
|
51 [..]
|
|
|
52 Three operation modes are available within this driver :
|
|
|
53
|
|
|
54 *** Polling mode IO operation ***
|
|
|
55 =================================
|
|
|
56 [..]

|
|
|
59
|
|
|

|
|
|
62 [..]

|
|
|
66 (+) Receive an amount of data in non blocking mode using HAL_SMARTCARD_Receive_IT()
|
|

|
|
|

|
|
|

|
|
|
71
|
|
|

|
|
|
180 [..]
|
|
|
181 This subsection provides a set of functions allowing to initialize the USART
|
|
|
182 in Smartcard mode.
|
|
|
183 [..]
|
|
|
184 The Smartcard interface is designed to support asynchronous protocol Smartcards as
|
|
|
185 defined in the ISO 7816-3 standard.
|
|
|
186 [..]
|
|
|
187 The USART can provide a clock to the smartcard through the SCLK output.
|
|
|
188 In smartcard mode, SCLK is not associated to the communication but is simply derived
|
|
|
189 from the internal peripheral input clock through a 5-bit prescaler.
|
|
|
190 [..]
|
|
|
191 (+) For the Smartcard mode only these parameters can be configured:
|
|
|
192 (++) Baud Rate
|
|
|
193 (++) Word Length => Should be 9 bits (8 bits + parity)
|
|
|
194 (++) Stop Bit
|
|
|
195 (++) Parity: => Should be enabled
|
|
|
196 +-------------------------------------------------------------+
|
|
|
197 | M bit | PCE bit | SMARTCARD frame |
|
|
|
198 |---------------------|---------------------------------------|
|
|
|
199 | 1 | 1 | | SB | 8 bit data | PB | STB | |
|
|
|
200 +-------------------------------------------------------------+
|
|
|
201 (++) USART polarity
|
|
|
202 (++) USART phase
|
|
|
203 (++) USART LastBit
|
|
|
204 (++) Receiver/transmitter modes
|
|
|
205 (++) Prescaler
|
|
|
206 (++) GuardTime
|
|
|
207 (++) NACKState: The Smartcard NACK state
|
|
|
208
|
|
|
209 (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
|
|
|
210 (++) Word Length = 9 Bits
|
|
|
211 (++) 1.5 Stop Bit
|
|
|
212 (++) Even parity
|
|
|
213 (++) BaudRate = 12096 baud
|
|
|
214 (++) Tx and Rx enabled
|
|
|
215 [..]
|
|
|
216 Please refer to the ISO 7816-3 specification for more details.
|
|
|
217
|
|
|
218 -@- It is also possible to choose 0.5 stop bit for receiving but it is recommended
|
|
|
219 to use 1.5 stop bits for both transmitting and receiving to avoid switching
|
|
|
220 between the two configurations.
|
|
|
221 [..]
|
|
|
222 The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
|
|
|
223 procedure (details for the procedure are available in reference manual (RM0329)).

|
|
|
364 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
|
|
|
365 [..]
|
|
|
366 Smartcard is a single wire half duplex communication protocol.
|
|
|
367 The Smartcard interface is designed to support asynchronous protocol Smartcards as
|
|
|
368 defined in the ISO 7816-3 standard. The USART should be configured as:
|
|
|
369 (+) 8 bits plus parity: where M=1 and PCE=1 in the USART_CR1 register
|
|
|
370 (+) 1.5 stop bits when transmitting and receiving: where STOP=11 in the USART_CR2 register.
|
|
|
371
|
|
|
372 (#) There are two modes of transfer:
|
|
|
373 (++) Blocking mode: The communication is performed in polling mode.
|
|
|
374 The HAL status of all data processing is returned by the same function
|
|
|
375 after finishing transfer.
|
|
|
376 (++) Non Blocking mode: The communication is performed using Interrupts
|
|
|
377 or DMA, These APIs return the HAL status.
|
|
|
378 The end of the data processing will be indicated through the
|
|
|
379 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
|
|
|
380 using DMA mode.
|
|
|
381 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
|
|
|
382 will be executed respectively at the end of the Transmit or Receive process
|
|
|
383 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
|
|
|
384
|
|
|
385 (#) Blocking mode APIs are :
|
|
|
386 (++) HAL_SMARTCARD_Transmit()
|
|
|
387 (++) HAL_SMARTCARD_Receive()
|
|
|
388
|
|
|
389 (#) Non Blocking mode APIs with Interrupt are :
|
|
|
390 (++) HAL_SMARTCARD_Transmit_IT()
|
|
|
391 (++) HAL_SMARTCARD_Receive_IT()
|
|
|
392 (++) HAL_SMARTCARD_IRQHandler()
|
|
|
393
|
|
|
394 (#) Non Blocking mode functions with DMA are :
|
|
|
395 (++) HAL_SMARTCARD_Transmit_DMA()
|
|
|
396 (++) HAL_SMARTCARD_Receive_DMA()
|
|
|
397
|
|
|
398 (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
|
|
|
399 (++) HAL_SMARTCARD_TxCpltCallback()
|
|
|
400 (++) HAL_SMARTCARD_RxCpltCallback()
