@par Example Description
This example describes a firmware Smartcard Interface based on the USART
peripheral. The main purpose of this firmware example is to provide resources
facilitating the development of an application using the USART peripheral in
smartcard mode.
The firmware interface is composed of library source files developed in order to
support ISO7816-3/4 specification, an application example is also provided.
This example is based on the AN2598 "Smartcard interface with the STM32F101xx
and STM32F103xx" application note. For more details, please refer to AN2598
available on www.st.com
@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
@note The application needs to ensure that the SysTick time base is always set to 1 millisecond
to have correct HAL operation.

@par Hardware and Software environment
- This example runs on STM32F407xx/417xx devices.
- This example has been tested with STMicroelectronics STM324xG-EVAL RevC
evaluation boards and can be easily tailored to any other supported device
and development board.
- STM324xG-EVAL RevC Set-up
- Use LED1, LED2, LED3 and LED4 connected respectively to PG.06, PG.08, PI.09
and PC.07 pins.
- Please ensure that jumper JP21 is fitted.
@par How to use it ?
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Run the example
