Arduino でチルト付き 5 ボタンマウスを試す
ATmega32U4 を利用した Arduino の Mouse ライブラリでは左、中央、右ボタンのマウスとなっています。これにチルト機能、進むおよび戻るボタンを追加してみます。
既存の Input Report に FB(Forward Button)、BB(Back Button) を追加します[1]。
| Input | D7 | D6 | D5 | D4 | D3 | D2 | D1 | D0 |
|---|---|---|---|---|---|---|---|---|
| 1 | 0 | 0 | 0 | (FB) | (BB) | MB | RB | LB |
X, Y, Wheel はそのままになります。
Back ボタンが D3 に、Forward ボタンが D4 になるように以下を追加してボタン指定に使用します。また、チルト用の引数を追加します。

以下でボタン数を増やします (USAGE_MAXIMUM を 3 から 5 に変更、REPORT_COUNT を 5 に変更、パッディングのサイズを 5 から 3 に変更)。さらに、チルト用の部分を追加します。
