+ IO operation functions + * + Peripheral State and Errors functions + * + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The SMARTCARD HAL driver can be used as follows: + + (#) Declare a SMARTCARD_HandleTypeDef handle structure. + (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API: + (##) Enable the USARTx interface clock. + (##) SMARTCARD pins configuration: + (+++) Enable the clock for the SMARTCARD GPIOs. + (+++) Configure these SMARTCARD pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT() + and HAL_SMARTCARD_Receive_IT() APIs): + (+++) Configure the USARTx interrupt priority. + (+++) Enable the NVIC USART IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA() + and HAL_SMARTCARD_Receive_DMA() APIs): + (+++) Declare a DMA handle structure for the Tx/Rx stream. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. + (+++) Configure the DMA Tx/Rx Stream. + (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream. + + (#) Program the Baud Rate, Word Length , Stop Bit, Parity, Hardware + flow control and Mode(Receiver/Transmitter) in the SMARTCARD Init structure. + + (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API: + (++) These APIs configure also the low level Hardware GPIO, CLOCK, CORTEX...etc) + by calling the customized HAL_SMARTCARD_MspInit() API. + [..] + (@) The specific SMARTCARD interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_SMARTCARD_ENABLE_IT() and __HAL_SMARTCARD_DISABLE_IT() inside the transmit and receive process. + + [..] + Three operation modes are available

his own code by customization of function pointer HAL_SMARTCARD_ErrorCallback + + *** SMARTCARD HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in SMARTCARD HAL driver. + + (+) __HAL_SMARTCARD_ENABLE: Enable the SMARTCARD peripheral + (+) __HAL_SMARTCARD_DISABLE: Disable the SMARTCARD peripheral + (+) __HAL_SMARTCARD_GET_FLAG
