GNU/Linux上の振動対応ジョイパッドデバイスの振動テストを行うGUIツールを作成
「PSX-CV02上の PlayStation 2コントローラの振動機能をGNU/Linux上で用いるための試行錯誤(Linux 2.6.31.5時点・第3回)」で振動のテストに用いたツールfftestは端末上で動作するプログラムでGUIの振動テストツールはなかったため、このソースを参考にして作ってみた。fftestは振動以外にも対応しているが、振動以外の種類に対応したデバイスは所有していない(動作が確認できない)ため、振動のみに対応したものとなる。
C言語で作成したものなので、GTK+ 2の開発パッケージ(lib(64)gtk+2.0_0-devel,libgtk2.0-devなどの名前)がインストールされている状態で
$ gcc -O2 $(pkg-config --cflags --libs gtk+-2.0 gmodule-2.0) [下のソースファイル] -o [実行ファイル]
としてコンパイルして実行する。また、Linuxカーネルのヘッダファイルも使用しているため、このパッケージ(linux-userspace-headers,linux-libc-devなどの名前)も入っていなければ必要となる。
GtkBuilderの機能を用いている(UI定義の記述はコード中に埋め込んでいる)ため、少なくともGTK+のバージョンは2.12以上が必要となる。作成した環境のGTK+はバージョン2.18系だが、GtkBuilder関係で問題が起こる可能性もあるため、なるべく新しいバージョンを用いることを推奨する。
コード
動作に大きな問題がないことは確認しているが、細かい部分で改善の余地がある可能性もあるため、バージョンを0.9とした。

使い方
振動機能が利用可能なデバイスの一覧が右上のコンボボックスに出るので、この中から使用したいデバイスを選択し、その下の
- Strong magnitude: 強い作動装置による振動の規模(強さ)
- Weak magnitude: 弱い作動装置による振動の規模(強さ)
- Length: 振動の長さ[秒]
- Delay: 振動開始のボタンを押した後実際に振動が始まるまでの時間[秒]
を調整した後で下部の「Rumble」ボタン(トグルボタン)を押す。
「PSX-CV02上の PlayStation 2コントローラの振動機能をGNU/Linux上で用いるための試行錯誤(Linux 2.6.31.5時点・第3回)」でも書いたが、安全のため、振動のテストをするときにはコントローラを手にしっかりと持っておくのがよい。
振動中は「Playing...」とステータスバーに表示される。
ボタンの状態は振動が終わったときに自動的に元に戻るが、振動中にもう一度押して強制的に止めることもできるようにした。
振動の長さと遅延の時間については内部的にはミリ秒単位で指定でき、範囲ももっと広いのだが、テストツールとして適した範囲として、長さは1-30秒,遅延は0-10秒の範囲に制限した。
