PIn for LINEin, MIC, LINEout

[alienx]

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..
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......


Thanks

I agree, that the terasic demonstration projects have incredible bad documentation quality. But the DE2_i2sound project is almost trivial, a few 100 lines Verilog and a small schematic top level. The WM8731 setup can be found in CLOCK_500.v, there's simply a list of commands (address + value) written to the codec, by changing the data you can set a different configuration. DE2_i2sound is operating the codec in bypass mode, just routing input to outputs, the digital audio interface isn't used at all.
