I want to capture input from the line in input on the board and convert it to digital for processing on FPGA without Nios II.
The examples on the CD weren't helpful. i2sound example bypasses the line in and mic inputs and directs them to line out.
I couldn't figure out how to configure the audio codec to capture the analog input and convert it to digital and send it to dac again to play the audio.
I am assuming that I need to use the slave mode operation. I wonder how I can see the captured input on a register in FPGA.
Any help will be appreciated!
Thanks in advance
