This information is processed and audio levels are adjusted accordingly. The information acquired by the Hammer from the various peripherals as well as the user interface are then sent to a SHARC ADSP-21262 over an SPI bus. These processors were all placed on an i2c bus and monitored and updated several times / second by the Hammer S3C2410A ARM920T Processor. The ATMEGA32A were used as peripheral processors that kept track of motorized faders as well as Rotary Pulse Generators (RPGS) and LED Bar graphs. The Hammer is not capable of processing audio at rates necessary for this project with all of the floating point calculations involved. Purdue ECE477 Team 2 Project Page Hardware 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. Of the above project success criteria, currently 2,3, and 4 are completed with the help of the Hammer ARM920T Chip. An ability to display the amplitude of an audio output signal. An ability to save and load scene settings (moving faders) An ability to display settings/ channel information on an LCD Display. An ability to change individual equalizer settings for each channel. An ability to mix and adjust levels of 6-8 Channels of Audio In order to pass this class at least 3 of 5 project success criteria must be completed. This was a Senior Design Project presented for Purdue University's Senior Design Class ECE 477. The Drink Mixer is a 6-8 Channel Audio Mixer with a peripheral interface operated by the Tin Can Tools Hammer.
