Final Year Project Report

8051-Based MP3 Player

In this engineering design subject, a simple 8051-based MP3 player is designed, developed, and constructed utilizing a set of systematic and scientific approaches. The MP3 player constructed in this project incorporates an AT89C51RD2 microcontroller which is functioned as the core component in the MP3 player circuit to coordinate and interface with other peripherals such as the LCD module, the SD card which purpose is to store MP3 files and the four functional buttons for user interface. The project was kick-started by collecting relevant information regarding the various operating conditions and maximum absolute ratings of the electronic components used. The hardware of the MP3 player was then constructed on two breadboards. A functional program was designed, developed and implemented to drive the MP3 player circuit. The program was written in ANSI-C programming language and compiled using SDCC compiler. There are a few challenges encountered during the process of project development. These problems include display failure of the second...
