我自己写的RFID读写程序(U2270)供大家参考

T5557是兼容e555x的RFID芯片，但又具备和e555x系列芯片不同的新性能。文章着重介绍了T5557的新特点及工作原理，并对其RSK工作模式下读写器的电路设计作了分析，最后给出了D类功放和FSK解调的应用电路。-T5557 is compatible e555x the RFID chip, but with different chips and e555x series of new features. T5557 article highlights the new features and working principle and its mode RSK reader an analysis of the circuit design, and finally give the Class D amplifier and the FSK demodulator circuit applications.

RFID资料，可以系统了解RFID的信息，非常适合初学者-RFID data, RFID can be systematic understanding of the information, very suitable for beginners

完美替换rc522，自带LPCD低功耗唤醒检卡，待机功耗大概10uA(Perfectly replace rc522 with LPCD with low power wake-up card. Standby power consumption is about 10uA)

详细地介绍了RFID现阶段的应用以及发展趋势-Detail the application of RFID at this stage as well as the development trend of

VC++编写对RFID卡进行读卡，写卡，等等操作，需要VB编程环境才能查看源代码。(VC++ for RFID card card read and write CARDS, and so on operation, VB programming environment is needed to view the source code.)
