mbed_official 87:085cde657901 21 (#) Declare a SMARTCARD_HandleTypeDef handle structure.
mbed_official 226:b062af740e40 22 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:
mbed_official 87:085cde657901 23 (##) Enable the USARTx interface clock.

mbed_official 87:085cde657901 43 (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API:
mbed_official 226:b062af740e40 44 (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc)
mbed_official 226:b062af740e40 45 by calling the customed HAL_SMARTCARD_MspInit() API.
mbed_official 226:b062af740e40 46 [..]
mbed_official 226:b062af740e40 47 (@) The specific SMARTCARD interrupts (Transmission complete interrupt,

mbed_official 87:085cde657901 167 ===============================================================================
mbed_official 87:085cde657901 168 [..]
mbed_official 87:085cde657901 169 This subsection provides a set of functions allowing to initialize the USART
mbed_official 87:085cde657901 170 in Smartcard mode.
mbed_official 87:085cde657901 171 [..]
mbed_official 87:085cde657901 172 The Smartcard interface is designed to support asynchronous protocol Smartcards as
mbed_official 87:085cde657901 173 defined in the ISO 7816-3 standard.
mbed_official 87:085cde657901 174 [..]
mbed_official 87:085cde657901 175 The USART can provide a clock to the smartcard through the SCLK output.
mbed_official 87:085cde657901 176 In smartcard mode, SCLK is not associated to the communication but is simply derived
mbed_official 87:085cde657901 177 from the internal peripheral input clock through a 5-bit prescaler.
mbed_official 87:085cde657901 178 [..]
mbed_official 87:085cde657901 179 (+) For the asynchronous mode only these parameters can be configured:
mbed_official 87:085cde657901 180 (++) Baud Rate
mbed_official 87:085cde657901 181 (++) Word Length
mbed_official 87:085cde657901 182 (++) Stop Bit
mbed_official 87:085cde657901 183 (++) Parity: If the parity is enabled, then the MSB bit of the data written
mbed_official 87:085cde657901 184 in the data register is transmitted but is changed by the parity bit.
mbed_official 87:085cde657901 185 Depending on the frame length defined by the M bit (8-bits or 9-bits),
mbed_official 226:b062af740e40 186 please refer to Reference manual for possible SMARTDARD frame formats.
mbed_official 87:085cde657901 187 (++) USART polarity
mbed_official 87:085cde657901 188 (++) USART phase
mbed_official 87:085cde657901 189 (++) USART LastBit
mbed_official 87:085cde657901 190 (++) Receiver/transmitter modes
mbed_official 87:085cde657901 191 (++) Prescaler
mbed_official 87:085cde657901 192 (++) GuardTime
mbed_official 87:085cde657901 193 (++) NACKState: The Smartcard NACK state
mbed_official 87:085cde657901 194
mbed_official 87:085cde657901 195 (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
mbed_official 87:085cde657901 196 (++) Word Length = 9 Bits
mbed_official 87:085cde657901 197 (++) 1.5 Stop Bit
mbed_official 87:085cde657901 198 (++) Even parity
mbed_official 87:085cde657901 199 (++) BaudRate = 12096 baud
mbed_official 87:085cde657901 200 (++) Tx and Rx enabled
mbed_official 87:085cde657901 201 [..]
mbed_official 87:085cde657901 202 Please refer to the ISO 7816-3 specification for more details.
mbed_official 87:085cde657901 203
mbed_official 87:085cde657901 204 -@- It is also possible to choose 0.5 stop bit for receiving but it is recommended
mbed_official 87:085cde657901 205 to use 1.5 stop bits for both transmitting and receiving to avoid switching
mbed_official 87:085cde657901 206 between the two configurations.
mbed_official 87:085cde657901 207 [..]
mbed_official 87:085cde657901 208 The HAL_SMARTCARD_Init() function follows the USART SmartCard configuration
mbed_official 87:085cde657901 209 procedure (details for the procedure are available in reference manual (RM0329)).

mbed_official 87:085cde657901 347 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
mbed_official 87:085cde657901 348 [..]
mbed_official 87:085cde657901 349 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
mbed_official 87:085cde657901 350 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
mbed_official 87:085cde657901 351 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
mbed_official 87:085cde657901 352 While receiving data, transmission should be avoided as the data to be transmitted
mbed_official 87:085cde657901 353 could be corrupted.
mbed_official 87:085cde657901 354
mbed_official 226:b062af740e40 355 (#) There are two modes of transfer:
mbed_official 87:085cde657901 356 (++) Blocking mode: The communication is performed in polling mode.
mbed_official 87:085cde657901 357 The HAL status of all data processing is returned by the same function
mbed_official 87:085cde657901 358 after finishing transfer.
mbed_official 226:b062af740e40 359 (++) Non Blocking mode: The communication is performed using Interrupts
mbed_official 226:b062af740e40 360 or DMA, These APIs return the HAL status.
mbed_official 87:085cde657901 361 The end of the data processing will be indicated through the
mbed_official 87:085cde657901 362 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
mbed_official 87:085cde657901 363 using DMA mode.
mbed_official 87:085cde657901 364 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
mbed_official 226:b062af740e40 365 will be executed respectivelly at the end of the Transmit or Receive process
mbed_official 226:b062af740e40 366 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
mbed_official 87:085cde657901 367
mbed_official 226:b062af740e40 368 (#) Blocking mode APIs are :
