微机接口作为计算机的一门基础性的学科，在计算机领域内发挥着重要的作用。应用十分广泛，如单片机的应用。所以学好这门课程对于我们来说是十分的重要。我在选题的时候就选择了并行通信，主要是完成两台机器之间的简单通信, 采用并行主要是考虑到效率高、速度快、操作简单方便等优点。-Computer Interface as a computer s basic disciplines, in the computer industry play an important role. A wide range of applications, such as single-chip applications. So learn this lesson for us is very important. In my time on the choice of topics parallel communications, primarily between the two machines to complete simple communications, parallel is mainly on account of high efficiency, fast, easy and convenient to operate and so on.
