@par Example Description
|
|
|
|
Firmware smartcard interface based on USART. The main purpose
|
|
of this firmware example is to provide resources that ease the development of applications
|
|
using the USART 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
|
|
|
|
ST sample Smartcard, provided with STM3210C-EVAL RevC board, contains a GSM SIM card
|
|
File System sample. This project implements following sequences taking place between
|
|
STM32 MCU and Smartcard :
|
|
- At power on, Board is waiting for card insertion (LED1 Blinking)
|
|
- As soon as card insertion is detected, card is power on, and a list of APDU Command/Response pairs
|
|
are exchanged between application and Smartcard, including PTS procedure (speed negotiation),
|
|
File Selection (MF, DF or EF), Information reading, File content reading (IMSI and ICCID)
|
|
- During this steps, all LEDS are turned on.
|
|
- When this sequence is completed, Smartcard is powered off, and waiting for user to remove card
|
|
from smartcard slot (LED1 blinking)
|
|
- Example is running in loop, so that at this stage, user is prompted again for card insertion ...
|
|
|
|
@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 need 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 STM32F1xx devices.
|
|
- This example has been tested with STMicroelectronics STM3210C-EVAL RevC
|
|
evaluation board (embedding a STM32F107xC device) and
|
|
can be easily tailored to any other supported device and development board.
|
|
|
|
- STM3210C-EVAL RevC Set-up
|
|
In order to get Smartcard corresponding I/O signals connected to smartcard interface chip,
|
|
please ensure JP11, JP12 and JP13 are set in position 1-2.
|
|
Connect a null-modem female/female RS232 cable between the DB9 connector
|
|
CN6 (USART2) and PC serial port if you want to display data on the HyperTerminal.
|
|
@note Make sure that jumper JP16 is 2-3 position (USART2_RX).
|
|
- USART2 connected to PC HyperTerminal could be used to follow Smartcard operations progress
|
|
UART to be configured as follow:
|
|
- BaudRate = 115200 baud
|
|
- Word Length = 8 Bits
|
|
- One Stop Bit
|
|
- No parity
|
|
- No Hardware flow control
|
|
|
|
|
|
@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
|
|
- Test output (description of running actions) is available on USART2. Please connect USART2 connector
|
|
to Hypterminal to follow test progress.
