mbed_official	205:c41fc65bcfb4	20	[..]
mbed_official	205:c41fc65bcfb4	21	The SMARTCARD HAL driver can be used as follows:
mbed_official	205:c41fc65bcfb4	22
mbed_official	205:c41fc65bcfb4	23	(#) Declare a SMARTCARD_HandleTypeDef handle structure.
mbed_official	205:c41fc65bcfb4	24	(#) Associate a USART to the SMARTCARD handle hsmartcard.
mbed_official	205:c41fc65bcfb4	25	(#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit ()API:

mbed_official	205:c41fc65bcfb4	36	__HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process.
mbed_official	205:c41fc65bcfb4	37	(##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA()
