一段ADSP21262用DAI口实现UART通讯的汇编源代码。

从事Profibus的开发人员可以利用改源代码理解profibus协议。添加除通讯以外的代码，很快可以开发出自己的智能节点-engaged in the development staff can use the source code to understand change Profibus agreement. Add except communications code, we will soon be able to develop their own intelligent nodes

一段源代码,希望能对初学者有所帮助,已调试通过.-Section of source code, hoping to be helpful for beginners have been debug through.

USB转串口的一个例子（源代码），可以在ＫＥＩＡＬ下直接编译。-USB to serial port of an example (source code)

plc中基于数据采集、发送接收、驱动、写入数据库-plc-based data acquisition, send to receive, drive, write to the database

音视频矩阵的串口控制程序，可以实现8进四出的控制。同时提供了udp监听，接收网络命令，实现网络上控制音视频矩阵。需要用到著名的trayicon控件和mscomm控件-audio and video matrix of Serial control procedures can be achieved eight into four control. While providing udp eavesdropping, the receiving network orders network control audio and video matrix. The need to resort to the famous trayicon controls and controls mscomm

串口控制程序一般分为查询和中断两者方式。查询方式适用于简单的应用，简单可靠，但是缺点是需要占用处理器资源，在发送或者接收数据的时候不能做其它的事情，处理器利用率低。中断方式下，在发送或者接受数据的时候处理器还可以做其它的工作，效率较高。-Serial control procedures will generally be divided into two way query and interruption. Query applied to simple applications, simple and reliable, but the drawback is the need to occupy processor resources to send or receive data at the time should not make other things, the processor utilization rate. Interrupt mode, the send or accept data when the processor can do other work, more efficient.
