摘 要
随着无线局域网技术的快速发展,无线终端已经融入了我们的生活,无论是智能手机还是笔记本,WiFi功能几乎是必不可少的。目前WiFi技术主要的应用还在手持终端,但随着用户需求的越来越广泛,WiFi技术也需要应用到不同的方面如工业控制,移动办公等,这就需要不同形式的终端。
本文开发并实现基于一种嵌入式开发平台的STM32的WiFi模块,使一些嵌入式设备也能够使用无线资源。论文首先讨论了基ARMCortex-M3的嵌入式开发技术,介绍了WiFi网络的发展现状及前景,利用STM32F103VCT6串口连接WiFi模块,介绍了UCGUI在STM32平台上的移植,最后,在此基础上进行基于uC/GUI的多窗口应用界面的设计,实现了WiFi热点接入界面的开发。

ABSTRACT
Today with the rapid development of wireless LAN technology, wireless terminals have been gradually integrated into our lives. WiFi function is almost essential whether it is a smart phone or a laptop. Currently the main application of WiFi technology still handheld terminal, but with the user's needs more and more widely, WiFi technology needs to be applied to different areas such as industrial control, mobile office, etc., which require different forms of terminals.
This paper developed and implemented an embedded development
platform based on the STM32 WiFi module, and enable some embedded devices to use the wireless resources. Firstly, we discuss the embedded development technology based on ARM Cortex-M3 , introduced a WiFi network development situation and prospects, using the serial port using the STM32F103VCT6 WiFi module, introduced in the STM32 platform UCGUI transplant, finally, on this basis, based uC / GUI application of multi-window interface design, to achieve a WiFi hotspot access interface development.
