bogdanm 0:9b334a45a8ff 22 (#) Associate a USART to the SMARTCARD handle hsc.
bogdanm 0:9b334a45a8ff 23 (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API:

bogdanm 0:9b334a45a8ff 311 This subsection provides a set of functions allowing to manage the SMARTCARD data transfers.
bogdanm 0:9b334a45a8ff 312
bogdanm 0:9b334a45a8ff 313 (#) There are two modes of transfer:
bogdanm 0:9b334a45a8ff 314 (+) Blocking mode: The communication is performed in polling mode.
bogdanm 0:9b334a45a8ff 315 The HAL status of all data processing is returned by the same function
bogdanm 0:9b334a45a8ff 316 after finishing transfer.
bogdanm 0:9b334a45a8ff 317 (+) No-Blocking mode: The communication is performed using Interrupts
bogdanm 0:9b334a45a8ff 318 or DMA, These API's return the HAL status.
bogdanm 0:9b334a45a8ff 319 The end of the data processing will be indicated through the
bogdanm 0:9b334a45a8ff 320 dedicated SMARTCARD IRQ when using Interrupt mode or the DMA IRQ when
bogdanm 0:9b334a45a8ff 321 using DMA mode.
bogdanm 0:9b334a45a8ff 322 The HAL_SMARTCARD_TxCpltCallback(), HAL_SMARTCARD_RxCpltCallback() user callbacks
bogdanm 0:9b334a45a8ff 323 will be executed respectively at the end of the Transmit or Receive process
bogdanm 0:9b334a45a8ff 324 The HAL_SMARTCARD_ErrorCallback()user callback will be executed when a communication error is detected
bogdanm 0:9b334a45a8ff 325
bogdanm 0:9b334a45a8ff 326 (#) Blocking mode API's are :
bogdanm 0:9b334a45a8ff 327 (+) HAL_SMARTCARD_Transmit()
bogdanm 0:9b334a45a8ff 328 (+) HAL_SMARTCARD_Receive()
bogdanm 0:9b334a45a8ff 329
bogdanm 0:9b334a45a8ff 330 (#) Non-Blocking mode API's with Interrupt are :
bogdanm 0:9b334a45a8ff 331 (+) HAL_SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 332 (+) HAL_SMARTCARD_Receive_IT()
bogdanm 0:9b334a45a8ff 333 (+) HAL_SMARTCARD_IRQHandler()
bogdanm 0:9b334a45a8ff 334 (+) SMARTCARD_Transmit_IT()
bogdanm 0:9b334a45a8ff 335 (+) SMARTCARD_Receive_IT()
bogdanm 0:9b334a45a8ff 336
bogdanm 0:9b334a45a8ff 337 (#) No-Blocking mode functions with DMA are :
bogdanm 0:9b334a45a8ff 338 (+) HAL_SMARTCARD_Transmit_DMA()
bogdanm 0:9b334a45a8ff 339 (+) HAL_SMARTCARD_Receive_DMA()
bogdanm 0:9b334a45a8ff 340
bogdanm 0:9b334a45a8ff 341 (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:
bogdanm 0:9b334a45a8ff 342 (+) HAL_SMARTCARD_TxCpltCallback()
bogdanm 0:9b334a45a8ff 343 (+) HAL_SMARTCARD_RxCpltCallback()
