Acoustic levitation

An acoustic levitation device designed as a daughterboard for the DE0-Nano-SoC (Terasic Inc.)

The piezoelectric transducers signals generation is written in VHDL. The phases computation and the G-Code interpreter are written in C and run on embedded Linux. The device controls 88 channels at 40 kHz with a phase resolution of π/625.
