通过串口来控制74hc4052（3.3v供电与cd4052有区别）来选择几路pwm的输出 已经调通并用在项目上 波特率为9600 pwm可以随意设置 16位定时器
并可以通过串口来控制pwm的产生 非常非常好用

这个是接着UART完整的APB的demo，里面有上文提到的整个工程，然后这还有个完成的带ARM核的demo，比较麻烦没有上传，如有需要，可以私聊，共同进步学习。

On this site you will find official information concerning the open source library libnfc for Near Field Communication (NFC) and other projects using this library. Since the RFID/NFC market is spoiled by proprietary hard and software we want to contribute constructively by distributing a free library and free tools which can be used for various RFID and NFC applications.
This website mainly focuses itself on researchers and developers willing to work with NFC hardware but without the pain of programming NFC software on a very low level. Libnfc does not require any license fee or non-disclosure agreement to be signed for. We hope to move NFC development to a more open culture where discussions about applications and techniques can be shared among the users.
