Visual C++をインストールする

というか、Visual Studioになるわけだが。 普通はCommunity Editionで問題ないと思うが、用途に応じてライセンスを選ぶこと。 インストールする際には、Windowsデスクトップ開発とかいうのを選ぶ。他はお好みで。 あー、確認してないけど、英語の言語パックは入れた方が多分いいです。入れないとだめかもしれない(thx hsbtさん)。

Helixのファームウェアは左手側のボードにUSBケーブルを繋ぐことを前提に作られている。 が、右手側に繋ぎたいことだってあるじゃん？ というわけで、どっちに繋いでも使えるようにしてみた。

まず、自分の使ってるファームウェアのディレクトリ内(例えばkeyboards/helix/rev2/keymaps/default)のkeymap.cの冒頭付近、
