摘要随着科学技术的发展,嵌入式设备的应用领域越来越广泛,如移动电话、家用电器、汽车……无不有它的踪影。嵌入式设备的应用环境也变得复杂多样,这样就可能导致在某些特殊环境下,人们是无法直接操作这些设备的,因此对该种设备远程控制技术的研究受到了国内外的广泛关注。目前采用UDP(User Datagram Protocol)通信,通过以太网传输数据来进行远程控制就是一种可行的办法。本设计核心为Luminary LM3S8962微处理器，其中央处理芯片采用基于ARMv7架构的Cortex处理器内核。本设计在嵌入式实时系统μC/OS-Ⅱ环境下编写程序，实现计算机与以太网接口RS232的UDP数据传输功能。64836

Design and Implementation of the Cortex-M3 ARM-based UDP protocol stack

Abstract With the development of science and technology, the embedded equipment is used more and more widely, such as mobile phones, home appliances, automobile...... No trace of it. The application environment of embedded devices is becoming more and more complicated, it may result in that people are unable to operate the equipment directly in some special circumstances, so the study of the technology of emote control with this kind of equipment has been widespread attention at home and abroad. At present, the remote control through the Ethernet data transmission is a kind of feasible solution for the UDP (User Datagram Protocol) communication. The design’s core is Luminary LM3S8962 microprocessor, the central processing chip is Cortex processor core which is based on ARMv7. This design programs with embedded real-time system μ C/OS- Ⅱ , it realizes UDP data transmission function from the computer to the RS232 Ethernet interface.
