The topic of my thesis was to develop a wireless sound system, primarily to be used in a school. This included the designing of the system structure, choosing the appropriate devices and develop the software architecture. It also included developing the software required for operation and designing and implementing the final hardware.
In the first part of my paper I describe the selected software and hardware solutions. I present the Texas Instruments CC3200 microcontroller which is the basis of the hardware, and also the operation of the UPnP protocol which I use to control the device and to transfer audio data over the network.
In the second part of my paper I detail the process of how I solved the task. First I present the steps of the software development, how I get from using the internal HTTP client of the CC3200 to start streamed audio playback through UPnP. Then follow the steps of preparing the PCB, creating the schematic and the PCB plan and finally soldering the components. The last step was to finalize and test the hardware.
