Example Description

This example provides a description of how to use the USART in Smartcard mode. The example gives only the possibility to read the ATR and decode it into predefined buffer. First, the code is waiting for an card insertion. If a card is detected through the EXTI Line interrupt (connected to the Smartcard detect pin), a reset signal is applied to the card through its reset pin. As response to this reset, the card transmit the ATR which will be stored in predefined buffer. Once the ATR is received, it is decoded and stored in a specific structure (SC_A2R) and the card protocol type is stored in a variable. ATRDecodeStatus variable must be equal to 1 (PASSED) when the sequence succeed.

The used Smartcard should be ISO7816-3 T=0 compatible.
