 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. This information is processed and audio levels are adjusted accordingly. (Currently the audio portion of the project is incomplete as too much crosstalk is occurring on the A/D Data line).

 ==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.
+The Drink Mixer is a 6-8 Channel Audio Mixer with a peripheral interface operated by the Tin Can Tools Hammer. This was a Senior Design Project presented for Purdue University's Senior Design Class ECE 477. In order to pass this class at least 3 of 5 project success criteria must be completed.

		+	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
