PIC30F2010 dsPIC controller 2 axis midi laser show

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 required MIDI instructions and output the waveform data via the SPI bus to a MCP4822 DAC Author: Scott Coppersmith

dsPIC30f2010 MIDI Laser Show Galvanometer Controller Circuit Cellar MicroChip 16-bit Embedded Control Design Contest 2007 Project Registration Number MT2163 In this example program characters pressed on the keyboard are sent to the device via usb. The device replicates the character back to the PC enclosed in quotes. Also this program blinks all four LEDs at 250ms by using timer 1
