bogdanm 0:9b334a45a8ff 19 The Extended SMARTCARD HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 20
bogdanm 0:9b334a45a8ff 21 (#) After having configured the SMARTCARD basic features with HAL_SMARTCARD_Init(),
bogdanm 0:9b334a45a8ff 22 then program SMARTCARD advanced features if required (TX/RX pins swap, TimeOut,
bogdanm 0:9b334a45a8ff 23 auto-retry counter,...) in the hsmartcard AdvancedInit structure.
