PIn for LINEin, MIC, LINEout

Altera_Forum · ‎10-23-2010

Hi Guys,

I am working on my cyclone 2 FPGA and I am applying my Noise cancellation technique in to it. I need to connect 2 MIC and a headphone to my FPGA so I want to incorporate the LINEin, MIC and LINEout pins but I dont know whats there PIN assignments are... Could someone help me by telling me the PINs for MIC, LINin and LINEout..

Thanks

A FPGA doesn't provide analog in- or outputs that would be needed for your project. Many development kits, e.g. the popular DE2 board has a codec chip to interface audio signals. The demonstration projects shipped with the board show the basic operation of the codec.

I have a cyclone 2 DE 1 board which is a Development kit. There is a demo for karaoke but I don't understand how to assigned MIC LINE in pin for my algorithm......

The input source selection is done by WM8731 control registers. Unfortunately I'm not using the development kit, so I can't give detail hints. Basically, the WM8731 datasheet should contain all necessary information.
