The DE2 Control Panel is based on a Nios II SOPC system instantiated in the Cyclone II FPGA with software running on the on-chip memory. The software part is implemented in C code; the hardware part is implemented in Verilog HDL code with SOPC builder. The source code is not available on the DE2 System CD.

The audio controller provides a simple interface to the Audio CODEC chip present on the DE2 board. The controller handles the data transmission to and from the chip. The chip configuration is handled by the separate configuration module. The configuration module must be instantiated separately when using the audio controller.

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.
