PIC30F2010 dsPIC controller 2 axis midi laser show

| 2010/05/24

This project is a dsPIC30F2010 based controller for a two axis laser show. The controller receives input as MIDI data, and controls X and Y beam deflection mirrors attached to open loop scanning galvanometers. PWM square waves don’t make very good galvo drive waveforms. The dsPIC30F series, however, is fast enough to both decode the…
