I am working on a project where I am required to code the WM8731 audio codec chip on the Altera DE1 board. The project is very basic. It does not need to process the input audio signals. The signal from the input should be directly relayed to the output. The main task is to set up the codec chip via the I2C protocol.

Connect your headset to the Line-out audio port on the DE1 board 5. Turn the RUN/PROG switch on the left edge of the DE1 board to RUN position; the PROG position is used only for the AS Mode programming 6. Turn the power on by pressing the ON/OFF switch on the DE1 board At this point you should observe the following: DE1 User Manual 9

The DE1 User Manual (PDF, pp. 40-41) is fairly explicit. You just need to check the -datasheet for the codec (Wolfson WM8731) to know how to talk to it. 1 level 1 davvik EE, CE 8 years ago I would think your Weiner bag (Wb) of a professor would provide you with documentation about these boards. 1 level 2 [deleted] 8 years ago
