RC522通过SPI方式读写M1卡.docx

1、RC522通过SPI方式读写M1卡1.准备工作战舰V3开发板，RC522模块为淘宝所买，赠送一张M1卡。SPI方式实测可以读写。2.RC522部分：rc522.h:/#include sys.h/MF522命令字/#define PCD_IDLE 0x00 /取消当前命令#define PCD_AUTHENT 0x0E /验证密钥#define PCD_RECEIVE 0x08 /接收数据#define PCD_TRANSMIT 0x04 /发送数据#define PCD_TRANSCEIVE 0x0C /发送并接收数据#define PCD_RESETPHASE 0x0F /复位#defin
