一般单片机应用系统的产品开发采用的是自下而上的过程,即根据应用的需求,选择相应的从器件进行系统的硬件设计、制作、调试到软件功能实现函数。在系统设计过程中,开发人员首先必须对特定硬件有较深入的了解,再总结出可以使用的方案。这种开发流程最大的弊端是,软件设计过程对 The general SCM application system product development uses a bottom-up process, that is, according to the needs of the application, select the appropriate slave system hardware design, production, debugging software functions to achieve the function. In the system design process, developers must first have a deeper understanding of specific hardware, and then sum up the available programs. The biggest drawback of this development process is the software design process
