摘要
介绍了一种基于Windows 2000/NT/XP下计算机并口与单片机进行数据通信的方法;提出了该方法以上位机向外设发中断脉冲的方法来实现数据通信的原理。在Windows下开发的通信程序,在满足技术要求下,可节省开发时间,具有很好的应用价值。
This paper introduces a method of the traffics data on computer parallel port and SCM based on Windows 2000/NT/XP. In this method, we give a theory that the data traffic can be achieved by launching interrupt pulse from a epigenous computer to external equipment. This kind communication programs can save exploitation time and have good applied worthiness.
