【正文】 rol, 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 CortexM3 , introduced a WiFi work 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 multiwindow interface design, to achieve a WiFi hotspot access interface development. Key words : STM32, WiFi, LCD,UC/GUI 目錄 III 目 錄 摘 要 ...........................................................................................................................
