因为单片机的种类多，而型号杂，也是我们学习中的困难，所以就MCS—51系列的产品来说，就是一个典型的学习方法。对于类似汇编的单片机编程过程，也是一个十分有趣的过程。为了更好的说明，我以上介绍先从应用电路切入，同时介绍它们的使用方法，以便能快速掌握它们的应用。-Because many kinds of SCM, while the hybrid model, but also we learn the difficulties, so the MCS-51 family of products, is a typical way of learning. A similar compilation for microcontroller programming process, but also a very interesting process. In order to better account, and I start with the application circuit cut into the above descr iption, and describe their use in order to be able to quickly grasp their applications.
