Advanced Operating Systems - Final Project A @ Tokyo Tech ////////////// Author: Chu Van Thiem and Sidik Soleman ////////////// A WAVE file player on the MBED Application Board with an interface to a software on PC via a TCP connection. ////////////// Main functions: 1. Browse files of an attached USB flash 2. The list of the files of the attached USB are displayed on the LCD 3. Use an joystick to select a WAVE file and give an instruction to play that file 4. Adjust the volume using a potentiometer 5. Output audio to the analog audio out jack ////////////// Software (https://github.com/thiemcv/VS/tree/master/Terminal): 1. Connect with the MBED application board via Ethernet connection 2. Read the list of files stored on the USB flash 3. Write files to the USB flash
Dependencies: C12832_lcd EthernetInterface USBHost mbed-rtos mbed wave_player
