mbed Synergy Audio CODEC Module

The Synergy AudioCODEC module converts stereo analogue audio signals to and from a single digital signal utilizing the I2S protocol. It is designed to work with the mbed LPC1768 microcontroller module. The AudioCODEC module is packaged in a convenient form factor for rapid prototyping using the popular TLV320AIC23B audio CODEC chip from Texas Instruments. Using industry standard I2C/SPI for control and I2S for data transfer, the TLV320AIC23B is capable of both recording and playing back audio at a range of resolutions and sample rates. The AudioCODEC module plugs into the Synergy AnimatronicLab board or standard breadboards.TLV320AIC23B audio CODEC device
