Power on the DE1 board, with the USB cable connected to the USB Blaster port. If
necessary (that is, if the default factory configuration of the DE1 board is not currently
stored in EPCS4 device), download the bit stream to the board by using either JTAG or AS
programming
You should now be able to observe that the 7-segment displays are displaying a sequence of
characters, and the red and green LEDs are flashing.
Optionally connect a VGA display to the VGA D-SUB connector. When connected, the
VGA display should show a pattern of colors.
Optionally connect a powered speaker to the stereo audio-out jack
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, the microphone-in port can be
connected to a microphone to hear voice sounds, or the line-in port can be used to play audio
from an appropriate sound source.
The Verilog source code for this demonstration is provided in the DE1_Default folder, which also
includes the necessary files for the corresponding Quartus II project. The top-level Verilog file,
called DE1_Default.v , can be used as a template for other projects, because it defines ports that
correspond to all of the user-accessible pins on the Cyclone II FPGA.
5.2 Music Synthesizer Demonstration
This demonstration shows how to implement a Multi-tone Electronic Keyboard using DE1 board
with a PS/2 Keyboard and a speaker. Figure 5.1 shows the setup of the demonstration.
PS/2 Keyboard is used as the piano keyboard for input. The Cyclone II FPGA on the DE1 board
serves as the Music Synthesizer SOC to generate music and tones. The VGA connected to the DE1
board is used to show which key is pressed during the playing of the music.
Figure 5.2 shows the block diagram of the design of the Music Synthesizer. There are four major
blocks in the circuit: DEMO_SOUND, PS2_KEYBOARD, STAFF, and TONE_GENERATOR. The
DEMO_SOUND block stores a demo sound for user to play; PS2_KEYBOARD handles the users’
input from PS/2 keyboard; The STAFF block draws the corresponding keyboard diagram on VGA
monitor when key(s) are pressed. The TONE_GENERATOR is the core of music synthesizer SOC.
User can switch the music source either from PS2_KEYBOAD or the DEMO_SOUND block using
SW9. To repeat the demo sound, users can press KEY1.
The TONE_GENERATOR has two tones: (1) String. (2) Brass, which can be controlled by SW0.
