Project overview • Block diagram • Design challenges • Individual contributions • Project demonstration • Questions / discussion Outline
Graphical Audio Visualizer to enhance environment at entertainment venue. • Wireless pillars about 3 ft. tall and 3 in. wide tubes. • Each pillar has custom frequencies set by user on mobile device. • LEDs in each pillar will light up according to amplitude of set frequency in song. • Mobile device will also control settings in base station. • Base station and towers will communicate wirelessly. Project Overview
The base station microcontroller traces melted • The tower microcontroller had to be fly-wired • The audio circuit had to be redesigned • The oscillator on the second tower microcontroller failed • The LED strand circuit • Bluetooth voltage issue Hardware Design Challenges
Register initializations • Xbee packet configuration • Bluetooth configuration setup • Peripheral timing • DSP library integration • Polling/interrupt driven combination Software Design Challenges
