【MM32F5270开发板试用】+RFID门禁
本篇文章来自极术社区与灵动组织的MM32F5270开发板评测活动，更多开发板试用活动请关注极术社区网站。作者：理想三旬
本次使用RFID-RC522模块与之前的1.8寸TFT实现门禁，通过主控循环检测RFID模块的信息，当接收到刷卡信息且核对通过后指示灯会闪，同时也开始计时，到5秒后自动关，同时将信息显示到屏幕上（拍照的时候拍不到屏幕上的信息）。
一、硬件设计
1.屏幕，这是使用的就是开发板的接口，使用I/O模拟的方式，将屏幕点亮。
2.RFID-RC522模块，这里使用的也是模拟的时序与模块通信，具体接线如下所示：
3.舵机，这里直接使用了开发板的接口，使用过的引脚是PA8，这里的电源需要外接，USB的电源不能直接作为舵机接口的电源。
4.LED，这里使用LED作为状态显示，显示读卡状态以及上锁状态
二、软件设计
1.timer1,这里使用了定时器1的基本功能，实现一个1s中断一次的效果，用来计时，当读到卡5s后自动关。

1.没有用卡识别时
2.用卡识别时，五秒后显示close door
四、总结
打算用ETH这个模块，不过发现官方只在用户手册中写了这部分，在mindsdk以及库函数中都没有这部分。希望官方后续能支持。
