STM32H735G-DK Piano Keyboard with Harmonics and Note Shaping
This small demonstration shows a small piano keyboard implemented on an STM32H735G-DK discovery kit. Each key pressed generates the appropriate frequency along with two additional harmonics. In addition, each note has an attack, sustain, decay, and release envelope applied for note shaping. There is also a frequency spectrum that can be displayed, which shows the main notes and harmonics.
