标题: stc15w408as和rfid-rc522如何进行刷卡求思路
各位大佬最近在做个刷卡功能的单片机，用的时stc15w408as，然后根据rc-522给的51单片机代码，改了下管脚定义，但是在上位机上却寻不到卡，有没有大佬能帮我看下怎么改才能正常工作

stc15w408as单片机的IO需要先设置工作模式，就是PxM0和PxM1要作相应设置才可以。

例如可以这样设置：P1M0 = 0x2C; P1M1=0x10; // P1.2 P1.3 P1.5为推挽输出模式 P1.4为高阻输入

P5M0 |= 0x10; P5M1 &= ~0x10; /0001 0000设置P5.4 为推挽输出模式
