EE2230 Logic Design Lab 1
Lab 10: Electronic Organ
Objective
ü Implement the electronic organ with different sound tones.
Prerequisite
ü Fundamentals of logic gates.
ü Keypad control
ü Frequency design of different tones
ü Logic modeling in Verilog HDL.
Experiments
1 Play the 16 sounds repeatedly based on the sound table. Every sound is played for one
second.
2 Electronic Organ
2.1 Integrate the keypad as the keyboard of the electronic organ. Keys A, 0, 1, 2, 3, 4, 5, 6,
7, 8, 9, B, C, D, E, F represent the sounds from low to high frequencies.
2.2 Display your playing sound (Do, Re, Mi, Fa, So, La, Si) in the 7-segment LED
3 (Bonus) Playback double tones by separate left and right channels. If you turn one DIP
switch off, the electronic organ playback single tone when you press keyboard (as in Prob.
2). If you torn DIP switch on, left (right) channels play Do(Mi), Re(Fa),Mi(So),Fa(La), So(Si)
when you press the keyboard.
