[Abstract]:With the development of embedded devices, including smart phones and embedded devices with Internet of things functions such as smart furniture into people's lives, people's lives become more and more intelligent. With the growing number of WLAN devices based on the WIFI Alliance that can connect families and units and small public places, The design of embedded devices which can connect wireless network has become a hot issue in the field of embedded research. In this paper, a solution of data transmission based on WLAN without operating system is proposed by using embedded chip STM32, which has the advantage of low cost. The occupation of resources is low. The main contents of this thesis are as follows:. The WLAN access hardware platform based on embedded chip STM32 is built. The main characteristics of STM32 microprocessor and its peripheral modules, such as SPI and serial port, are introduced. At the same time, the WLAN module, which is used as wireless network driver, is described. The open source uIP embedded protocol stack is cut, and the protocol stack is selectively transplanted to the STM32 device according to the actual requirements of the project. The design of the underlying driver interface and the application layer interface of the embedded protocol stack is realized. Build a stable miniature TCP/IP protocol stack. The driving principle of WLAN chip is studied. According to the standard WLAN chip driver model and the interactive mode of host driver and firmware, the bottom driver of WLAN is designed to realize the functions of firmware download, search test, connection test and so on. Complete the function of building Ad-Hoc and basic network. VC Socket client is programmed based on MFC library function, and the communication test between PC and STM32WLAN embedded system is realized. Based on JAVA, the mobile intelligent terminal and embedded WLAN system are realized by writing mobile phone Android client software. Temperature data acquisition is realized.
