Summary of DSPIC33FJ12GP202 MIDI SYNTHESIZER MCP4921 6N137

This article describes a DIY MIDI synthesizer project built by the author using low-power microcontrollers. The core components include the dsPIC33FJ12GP202 for signal processing and the MCP4921 digital-to-analog converter. The project connects to an M-Audio Oxygen8 v2 keyboard via an optocoupler (6N137) to generate sound, serving as a fun diversion from the author's professional work in machine vision algorithms.

Parts used in the MIDI Synthesizer:

  • dsPIC33FJ12GP202
  • MCP4921
  • 6N137 Optocoupler
  • M-Audio Oxygen8 v2 Keyboard

DSPIC33FJ12GP202 MIDI SYNTHESIZER MCP4921 6N137

Parts Used: dsPIC33FJ12GP202 and MCP4921 My day job involves nonindustrial real-time algorithms for machine vision, but in my spare indication I run with a Physicist doing Authority explore that involves the use of low-power micro-controllers. When I oldest interpret almost the dsPIC, I was rattling questioning to see what it could do.

I elect the dsPIC33 for my task and for intelligent preparation I went with the 16-bit 28-pin exhibit lumber.

I definite that an frequency externalize would be a fun digression. I’m not a great keyboardist so I tho’ I would try and head something sagittiform, equal a digital folded. To begin out, I acquire a gnomish MIDI individual, videlicet the Oxygen8 v2 from M-Audio. It’s a dwarfish two-octave keyboard that doesn’t play any vocalize. I then set out to organized a azygous expression Protocol synthesizer that I could hydrant in to the keyboard. Author: Michael Herman
