Drink Mixer (Audio Mixer)

This project was titled the Drink Mixer as a joke cause one team member wanted to make that instead of a sound mixer so we kept that as the name.

More information and pictures will be added to this later but for now a link to the Purdue University Senior Design Project Page for this project can be found below.

Hardware

The Hammer is not capable of processing audio at rates necessary for this project with all of the floating point calculations involved. As a result several processors were used

 1  - ADSP-21262 SHARC DSP
10 - AVR ATMEGA32A


The ATMEGA32A were used as peripheral processors that kept track of motorized faders as well as Rotary Pulse Generators (RPGS) and LED Bar graphs. These processors were all placed on an i2c bus and monitored and updated several times / second by the Hammer S3C2410A ARM920T Processor.
