EasyARM2131 one source development board

这是一个基于stm32的程序文件，通过DMA方式的spi通信，部分功能按自己需求自己添加，部分引脚按自己情况稍加修改。

STM32 MP3 播放的实现代码，可以在开发板上直接运行，使用方便快捷，具体内容请看代码，具体使用方法可以参考文章http://www.openedv.com/posts/list/36595.htm。

该代码实现的是路由器收发的功能。这种功能为了实现Bacnet楼宇设备间设备而设计的。BACnet是一个为嵌入式系统实现的BACnet （楼宇自动化和控制网络）专门协议。 BACnet本身就是一个标准的路由协议设计用于处理通信自动化的建筑，如空调系统和其他暖通设备。楼宇自动控制网络数据通讯协议（即： A Data Communication Protocol for Building Automation and Control Networks，简称《BACnet协议》）由美国暖通、空调和制冷工程师协会(ASHRAE ) 组织的 标准项目委员会135P (Stand Project Committee即SPC 135P)历经八年半时间开发的。
