The CII_Starter_Default folder contains the Verilog source code for this
demonstration. It also includes the necessary files for the corresponding
Quartus II project. The top-level CII_Starter_Default.v Verilog file can
serve as a template for other projects, because it defines ports that
correspond to all of the user-accessible pins on the Cyclone II FPGA.
This demonstration shows how to implement a multi-tone electronic
keyboard using the development board with a PS/2 keyboard and a
speaker.
Use the PS/2 keyboard as the piano keyboard for input. The Cyclone II
FPGA on the development board serves as the Music Synthesizer System
on Chip (SOC) to generate music and tones. The VGA monitor connected
to the development board shows which key is pressed during the playing
of the music.
Place toggle switch SW9 in the UP position to hear a 1 kHz
humming sound from the audio-out port. Alternatively, if switch
SW9 is DOWN, connect the Mic In port to a microphone to hear
voice sounds or use the line-in port to play audio from an
appropriate sound source.
Figure 6–1
shows the setup of the demonstration.
