RC522串口驱动代码

以下是一个使用串口进行RC522读写的驱动程序的示例代码：

#include "stm32f10x.h"
#include "uart.h"
#include "sys.h"
#include "rc522.h"

int main(void) {
    u8 IC\[50\] = {0};
    delay_init();
    UART1_init();
    delay_ms(2000);
    RC522_Init();
    printf("RC522_UART_TEST...\r\n");
    printf("写卡开始...\r\n");
    while(!RC522_WRITE((u8 *)"12121212")){};
    printf("写卡成功...\r\n");
    while(1){
        if(RC522_READ(IC)){
            printf("%s\r\n",IC);
            delay_ms(500);
        }
        delay_ms(100);
        printf("waitting...\r\n");
    }
}

这段代码是在Linux系统下编写MF-RC522模块驱动的示例。它使用了串口进行通信，并配合应用层完成IC卡号的读取、扇区的读写和密码验证等操作。该代码是针对友善之臂Tiny4412开发板和三星的EXYNOS4412芯片编写的，没有采用SPI子系统，而是直接控制IO口模拟SPI时序与MF-RC522进行通信。代码中包含了写卡和读卡的测试，经过亲测可以正常使用。
