Twitter Controlled Real Time Audio Synthesizer Based On Xmos Platform

This paper describes one solution of the audio system based on xCORE architecture of XMOS company. xCORE microcontroller is connected to the Cirrus Logic development board (used as the audio output) via I2S (Integrated-Interchip Sound) and I2C (Inter-Integrated Circuit) serial interface where digital to analog conversion is done. Microcontroller from Twitter servers downloads tweets that contain musical notes, generates musical tones and sends it (in basic form or delayed - echo effect) to the audio output.
