C指针在嵌入式系统开发中的方法研究

摘要

Embedded technology-based service,with a high degree of automation,fast response,etc,but the development of embedded technology,based programming language,there are a variety of existing language,choose a suitable language is crucial.C language development of embedded systems with respect to the efficiency and flexibility in other language, proficiency in C pointer, not only makes code optimization, but also improve the efficiency of the system. In this paper, the characteristics of embedded systems, addressed from a pointer, the pointer reference array elements, dynamic application memory space, function pointers, as well as wild pointer on the efficient use of C pointers embedded system development.%以嵌入式技术为基础的服务性产品，它具自动化程度高、响应速度快等优点，但开发嵌入式技术，需要以编程语言为基础，目前存在的语言有很多种，选择一种合适的语言至关重要。C语言开发嵌入式系统相对于其他语言来说具有高效性与灵活性，掌握C 指针的利用，不仅使得代码优化，而且可以提高系统的运行效率。文章结合嵌入式系统的特点，从指针寻址，指针引用数组元素，动态申请内存空间，函数指针还有避免野指针等几个方面，阐述了高效利用C指针进行嵌入式系统开发。
