Developing a touchscreen driven music player with C++ and FreeRTOS

Abstract

This thesis describes the research and work done during each step of the development of a touch-screen music player on a Cortex-M microcontroller. Using FreeRTOS and developed in C++ the resulting software perform internal and external peripherals configuration, present a graphical user interface and process inputs on a touchscreen, retrieve files stored on an SD card, parse a tracker music format, control programmable sound generators installed on an expansion board and process the resulting signal with an audio codec.
