Playing the Piano on a black fin Scott Pio ECE 3551 – Microcomputers Dr. Kepuska

Problem Statement: The original idea was to just have frequencies go up and down when button one (up) and button two (down) were pushed. I then integrated the idea to playing the piano.

Background of a piano  Piano has 88 keys meaning 88 different frequencies

Integration into black fin  Blackfin only has 4 keys  Had to make an Array of 64.  Wanted to show what key that was coming through with the LED’s  This is the reason for 64 frequencies only

Button declarations  First button goes up one Frequency while adding bit 1 to led lights.  Second button goes down one frequency while subtracting bit lights.

Accomplishments  Had a completely successful project.  Side Note: Noticed frequency oscillate the actual table I was working on. Experimented with the actual frequencies and found small oscillations inside the table it self.  If we had more buttons on the board it self, we would have been able to mimic a piano.
