此文件是百合电子工作室推出的USB开源项目：Easy USB 51

Programer的一部分。



　 Easy USB 51 Programer 是一个多功能的USB学习板（USB接口

芯片采用philips的pdiusbd12），通过此项目，您不仅可以学习到

USB HID设备类的开发（包括下位机固件驱动的编写和上位机应用

程序的编写），还可以学习UB的其它标准设类（如USB Mass

Storage）及自定义的非标准设备类的开发。Easy USB 51

Programer 开放了一些 I/O 口 ，我们还可以利用这些开放的 I/O

口扩展一些应用，如此项目的一个扩展板（EXT-BOARD-A）就是利

用了开放的一些 I/O 口来实现按键、LED、和串行通讯等功能。-This file is the electronic studio announced USB lily open source project: Easy USB 51

　Easy USB 51 Programer study is a multi-board USB (USB interface

　chip philips the pdiusbd12), through this project, you can learn not only

　 USB HID class device development (including lower firmware-driven writing and PC applications

　 the preparation process), you can also learn other standard USB devices (such as USB Mass

　Storage) and non-standard equipment, custom class development. Easy USB 51

　Programer open a number of I/O port, we can also take advantage of these open I/O

　 mouth to extend some applications, such an extension of the project board (EXT-BOARD-A) is the interest

　open with some I/O port to achieve the key, LED, and serial communication functions.
