DDS running at audio clock rate is connected to the audio codec DAC channels. Code. Quartus Archive. The output frequency is set as F = (SW*(2^14))*(audio clock rate)/(2^32) = SW*(audio clock rate)*(2^-18) = SW*46000*(2^-18) The 2^14 is an scale factor to put the frequency into the audio range. The 2^32 results from using a 32 bit accumulator.

Hello, I am attaching a VHDL file which describes an interface to the Wolfson WM8731 Audio Codec chip located on the Altera DE1 and DE2 boards. This version just does output, but you can augment it to do input. For this you will have to read over the WM8731 datasheet. I have tested this on both the DE1 and DE2 boards.

DE2 Clock is a clock/timer that uses the DE2's LCD to display the current time. A VHDL-based state machine is used to communicate with the LCD display controller. The Key2 pushbutton resets the time. All VHDL source code is included. Rapid Prototyping of Digital Systems SOPC Edition now available from Springer Publishing ISBN 978-0-387-72670-0.
