本例是基于STM32F407完成对。本代码主要完成MP3播放，界面显示等功能，还可在此基础上外扩点阵屏实现LED显示功能！(This case is based on the completion of the STM32F407. The code is mainly to complete MP3 playback, interface display and other functions, can also be based on the expansion of LED dot matrix screen display function!)

使用方法： 程序设置了ENC28J60的IP为192.168.0.15，模块通电后与电脑的网口用网线连接起来， 设置电脑的本地IP为192.168.0.**（**自定），网关为192.168.0.15,其他默认，配置 成功后便可以arp或ping模块。 打开浏览器，在地址里输入http://192.168.0.15/123456可打开开发板简单网页，页 面上通过按键来控制开发板LED的亮灭。(Use: setup the ENC28J60 of IP to 192.168.0.15, the module is powered on the computer' s Ethernet port using a cable connection up to set the computer' s local IP 192.168.0.** (** Custom), the gateway 192.168.0.15, default configuration is successful, it will make arp or ping module. Open the browser, enter the address http://192.168.0.15/123456 to open the development board simple web pages, and page keys to control the development board LED light off.)
