掌握单片机的应用开发需要一个过程。首先必须掌握数字电路和模拟电路方面的知识，还必须学习单片机原理、硬件结构、扩展接口和编程语言。初次开发时由于没经验，可能要经过多次反复才能完成项目。这时，你会得到较大的收获和积累，表现在以下几个方面：

1) 硬件设计方面的积累；

2)软件设计方面的积累；

3)设计经验方面的积累。-Master microcontroller application development requires a process. Must first master the knowledge of digital and analog circuits, also must learn microcontroller principle, hardware structure, expansion interfaces and programming languages​ ​ . Initial development, no experience, you may have to go through repeated many times in order to complete the project. At this time, you will get a larger harvest and accumulated performance in the following areas:

        1) the accumulation of hardware design

        2) accumulation of software design

        3) the accumulation of experience in the design aspect.
