Fork of NuMidi401 by Yuu Kobayashi

NuFM401

Nucleo F401用の自作ソフトウェアMIDI音源

概要

だいたいそんなもんです。

特徴

  • ブレッドボードの上で組める程度には簡単な回路構成
  • 外部のDACにMCP4922を採用
  • 念のためのボルテージフォロアとしてNJM2737Dを採用
  • バンク用EEPROMに24FC1025を採用
  • シリアル経由でMIDIデータを受信することで操作

補足

シリアル <=> MIDI のドライバにはHairless-MIDISerialをオススメします。 仮想MIDIケーブルはとりあえずMIDI Yokeで。
