This master’s thesis focuses on the development of an embedded radio receiver platform supporting the DAB+ standard and MP3 playback, specifically designed for individuals with special needs. The introductory part of the thesis analyzes the DAB standard, its core principles, and provides a comparison with alternative broadcasting technologies. Based on technical and user requirements, a systematic selection of hardware components was performed, followed by the design of the system’s block architecture and power supply circuits. This phase also includes power consumption calculations across various operating modes. Prior to the actual production of the platform, a configuration of development kits was assembled to verify the concept and facilitate subsequent software development. The software development encompassed the selection of the ecosystem, libraries, and core software principles, which formed the basis for the software architecture design. Furthermore, the thesis describes the user interface and device control, including a state diagram, the principle of audio signal processing, the audio data flow, and a voice feedback mixing algorithm. Validation performed on the manufactured prototype running the implemented software confirmed the functionality of the platform as a whole, demonstrated compliance with the predetermined requirements, and verified the actual power consumption alongside the percentage utilization of system resources.
