Sammanfattning
Wi-Fi connectivity is becoming present in more and more places and devices. This opens up for new and innovative ways to use Wi-Fi technology compared to the Personal Computer (PC) to PC network it was rst intended for. In this thesis a solution for a Wi-Fi extension module together with software for using the extension module to remote control an audio platform developed by Bohmer Audio has been researched and constructed. The Wi-Fi expansion module solution was developed by researching what Wi-Fi chip solutions were available on the market and then choosing one solution that is optimised for low price, ease of use and bandwidth. A printed circuit board (PCB) for the TiWi-SL WiFi chip that was chosen has been developed and constructed. The software part of the thesis consist of low level serial peripheral interface (SPI) drivers developed in C code for an AVR microcontroller used in the communication with the WiFi extension module. To remote control the Audio platform, server and client software have also been implemented. The server side software consists of a HyperText Transfer Protocol (HTTP) server programmed in C code which lets the client access a web interface written in HyperText Markup Language (HTML) and Javascript that controls the audio platform. The web interface layout is automatically generated by a script written in Python that parses an Extensible Markup Language (XML) le provided by Bohmer Audio.
