Objective
Implement the electronic organ with different sound tones.
Prerequisite
Fundamentals of logic gates.
Keypad control
Frequency design of different tones
Logic modeling in Verilog HDL.
Experiments
Play the 16 sounds repeatedly based on the sound table. Every sound is played for one second.
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
(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.
