mbed_official 133:d4dda5c437f0 168 [..]
mbed_official 133:d4dda5c437f0 169 This subsection provides a set of functions allowing to initialize the USART
mbed_official 133:d4dda5c437f0 170 in Smartcard mode.
mbed_official 133:d4dda5c437f0 171 [..]
mbed_official 133:d4dda5c437f0 172 The Smartcard interface is designed to support asynchronous protocol Smartcards as
mbed_official 133:d4dda5c437f0 173 defined in the ISO 7816-3 standard.
mbed_official 133:d4dda5c437f0 174 [..]
mbed_official 133:d4dda5c437f0 175 The USART can provide a clock to the smartcard through the SCLK output.
mbed_official 133:d4dda5c437f0 176 In smartcard mode, SCLK is not associated to the communication but is simply derived
mbed_official 133:d4dda5c437f0 177 from the internal peripheral input clock through a 5-bit prescaler.
mbed_official 133:d4dda5c437f0 178 [..]
mbed_official 133:d4dda5c437f0 179 (+) For the asynchronous mode only these parameters can be configured:
mbed_official 133:d4dda5c437f0 180 (++) Baud Rate
mbed_official 133:d4dda5c437f0 181 (++) Word Length
mbed_official 133:d4dda5c437f0 182 (++) Stop Bit
mbed_official 133:d4dda5c437f0 183 (++) Parity: If the parity is enabled, then the MSB bit of the data written
mbed_official 133:d4dda5c437f0 184 in the data register is transmitted but is changed by the parity bit.
mbed_official 133:d4dda5c437f0 185 Depending on the frame length defined by the M bit (8-bits or 9-bits),
mbed_official 242:7074e42da0b2 186 please refer to Reference manual for possible SMARTDARD frame formats.
mbed_official 133:d4dda5c437f0 187 (++) USART polarity
mbed_official 133:d4dda5c437f0 188 (++) USART phase
mbed_official 133:d4dda5c437f0 189 (++) USART LastBit
mbed_official 133:d4dda5c437f0 190 (++) Receiver/transmitter modes
mbed_official 133:d4dda5c437f0 191 (++) Prescaler
mbed_official 133:d4dda5c437f0 192 (++) GuardTime
mbed_official 133:d4dda5c437f0 193 (++) NACKState: The Smartcard NACK state
mbed_official 133:d4dda5c437f0 194
mbed_official 133:d4dda5c437f0 195 (+) Recommended SmartCard interface configuration to get the Answer to Reset from the Card:
mbed_official 133:d4dda5c437f0 196 (++) Word Length = 9 Bits
mbed_official 133:d4dda5c437f0 197 (++) 1.5 Stop Bit
mbed_official 133:d4dda5c437f0 198 (++) Even parity
mbed_official 133:d4dda5c437f0 199 (++) BaudRate = 12096 baud
mbed_official 133:d4dda5c437f0 200 (++) Tx and Rx enabled
mbed_official 133:d4dda5c437f0 201 [..]
mbed_official 133:d4dda5c437f0 202 Please refer to the ISO 7816-3 specification for more details.
mbed_official 133:d4dda5c437f0 203
mbed_official 133:d4dda5c437f0 204 -@- It is also possible to choose 0.5 stop bit for receiving but it is recommended
mbed_official 133:d4dda5c437f0 205 to use 1.5 stop bits for both transmitting and receiving to avoid switching
mbed_official 133:d4dda5c437f0 206 between the two configurations.

mbed_official 133:d4dda5c437f0 347 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
mbed_official 133:d4dda5c437f0 348 [..]
mbed_official 133:d4dda5c437f0 349 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
mbed_official 133:d4dda5c437f0 350 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
mbed_official 133:d4dda5c437f0 351 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
mbed_official 133:d4dda5c437f0 352 While receiving data, transmission should be avoided as the data to be transmitted
mbed_official 133:d4dda5c437f0 353 could be corrupted.
mbed_official 133:d4dda5c437f0 354
mbed_official 242:7074e42da0b2 355 (#) There are two modes of transfer:
mbed_official 133:d4dda5c437f0 356 (++) Blocking mode: The communication is performed in polling mode.
mbed_official 133:d4dda5c437f0 357 The HAL status of all data processing is returned by the same function
mbed_official 133:d4dda5c437f0 358 after finishing transfer.
mbed_official 242:7074e42da0b2 359 (++) Non Blocking mode: The communication is performed using Interrupts
mbed_official 242:7074e42da0b2 360 or DMA, These APIs return the HAL status.
mbed_official 133:d4dda5c437f0 361 The end of the data processing will be indicated through the
mbed_official 133:d4dda5c437f0 362 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
mbed_official 133:d4dda5c437f0 363 using DMA mode.
mbed_official 133:d4dda5c437f0 364 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
mbed_official 242:7074e42da0b2 365 will be executed respectivelly at the end of the Transmit or Receive process
mbed_official 242:7074e42da0b2 366 The HAL_SMARTCARD_ErrorCallback() user callback will be executed when a communication error is detected
mbed_official 133:d4dda5c437f0 367
mbed_official 242:7074e42da0b2 368 (#) Blocking mode APIs are :
