摘要
针对PSAM卡的驱动操作,并且兼容ISO7816协议里规定的使用相对较多的A类和B类两种类型的PSAM卡,采用STM32单片机为主控模块,以及相应的电压转换模块,成功实现了对于A类、B类两种类型的PSAM卡的驱动。具体阐述了PSAM卡接口信号的电路设计及函数接口。
For PSAM card driver operation, PSAM card is compatible with Class A and Class B two types of ISO7816 protocol. STM32 microcontroller is used as the master module and a corresponding voltage converter module, successfully realizing the Class A, Class B two types of PSAM card driver. PSAM card interface signal circuit design and function interface are specifically addressed.
