7.5.1. About the ISO7816 driver

7.5.1.1. Principles

The ISO7816 driver implements the low level layer of the ISO7816-3 protocol. It configures the SMARTCARD mode of the STM32F4 MCUs USARTs (see the datasheet of the MCU for more information about this mode). The driver also implements the card detection GPIO monitoring, and executes a registered callback when the smart card is inserted or removed.
