| mbed_official | 610:813dcc80987e | 17 | ##### How to use this driver ##### |
| mbed_official | 610:813dcc80987e | 18 | ============================================================================== |
| mbed_official | 610:813dcc80987e | 19 | [..] |
| mbed_official | 610:813dcc80987e | 20 | The SMARTCARD HAL driver can be used as follows: |
| mbed_official | 610:813dcc80987e | 21 | |
| mbed_official | 610:813dcc80987e | 22 | (#) Declare a SMARTCARD_HandleTypeDef handle structure (eg. SMARTCARD_HandleTypeDef hsmartcard). |
| mbed_official | 610:813dcc80987e | 23 | (#) Associate a USART to the SMARTCARD handle hsmartcard. |
| mbed_official | 610:813dcc80987e | 24 | (#) Initialize the SMARTCARD low level resources by implementing the HAL_SMARTCARD_MspInit() API: |
| mbed_official | 610:813dcc80987e | 25 | (++) Enable the USARTx interface clock. |
| mbed_official | 610:813dcc80987e | 26 | (++) USART pins configuration: |
| mbed_official | 610:813dcc80987e | 27 | (+++) Enable the clock for the USART GPIOs. |
| mbed_official | 610:813dcc80987e | 28 | (+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input). |
| mbed_official | 610:813dcc80987e | 29 | (++) NVIC configuration if you need to use interrupt process (HAL_SMARTCARD_Transmit_IT() |
| mbed_official | 610:813dcc80987e | 30 | and HAL_SMARTCARD_Receive_IT() APIs): |
| mbed_official | 610:813dcc80987e | 31 | (++) Configure the USARTx interrupt priority. |
| mbed_official | 610:813dcc80987e | 32 | (++) Enable the NVIC USART IRQ handle. |
| mbed_official | 610:813dcc80987e | 33 | (++) DMA Configuration if you need to use DMA process (HAL_SMARTCARD_Transmit_DMA() |
| mbed_official | 610:813dcc80987e | 34 | and HAL_SMARTCARD_Receive_DMA() APIs): |
| mbed_official | 610:813dcc80987e | 35 | (+++) Declare a DMA handle structure for the Tx/Rx channel. |
| mbed_official | 610:813dcc80987e | 36 | (+++) Enable the DMAx interface clock. |
| mbed_official | 610:813dcc80987e | 37 | (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. |
| mbed_official | 610:813dcc80987e | 38 | (+++) Configure the DMA Tx/Rx channel. |
| mbed_official | 610:813dcc80987e | 39 | (+++) Associate the initialized DMA handle to the SMARTCARD DMA Tx/Rx handle. |
| mbed_official | 610:813dcc80987e | 40 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel. |
| mbed_official | 610:813dcc80987e | 41 | |
| mbed_official | 610:813dcc80987e | 42 | (#) Program the Baud Rate, Parity, Mode(Receiver/Transmitter), clock enabling/disabling and accordingly, |
| mbed_official | 610:813dcc80987e | 43 | the clock parameters (parity, phase, last bit), prescaler value, guard time and NACK on transmission |
| mbed_official | 610:813dcc80987e | 44 | error enabling or disabling in the hsmartcard handle Init structure. |
| mbed_official | 610:813dcc80987e | 45 | |
| mbed_official | 610:813dcc80987e | 46 | (#) If required, program SMARTCARD advanced features (TX/RX pins swap, TimeOut, auto-retry counter,...) |
| mbed_official | 610:813dcc80987e | 47 | in the hsmartcard handle AdvancedInit structure. |
| mbed_official | 610:813dcc80987e | 48 | |
| mbed_official | 610:813dcc80987e | 49 | (#) Initialize the SMARTCARD registers by calling the HAL_SMARTCARD_Init() API: |
| mbed_official | 610:813dcc80987e | 50 | (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc) |
| mbed_official | 610:813dcc80987e | 51 | by calling the customized HAL_SMARTCARD_MspInit() API. |
