Functional Description

The Analog Shield is a low cost digital signal processing Shield designed to work with the Arduino UNO and ChipKIT line of microcontroller boards. It was created in collaboration with Stanford University, the TI University Program and Digilent Inc.

The following demos are currently available on the Arduino: FFT Spectrum Visualizer : (create link) https://github.com/wespo/FFT_Visualizer Direct Digital Synthesis Function generator: (create link) https://github.com/wespo/DDS_Generator Lissajou Pattern Generator: (create link) https://github.com/wespo/Lissajous_curve Polyphonic MIDI Player: (create link) https://github.com/wespo/Polyphonic_music

The Analog Shield is designed with TI analog technology that provides up to 4 channels of 16-bit analog signal input and output. Also on board are integrated fixed +/-5V and variable +/- 7.5V power supplies.
