ゲームコントローラとして、SparkFun Pro Micro（たぶん中華製互換機）を3つPCにつなげています。ひとつはKeyBoardとしての利用ですが、他の2つはUSBコントローラです。ちゃんと区別してPCが認識してくれるのか不安でしたが、問題なさそうです。
Pro Microのpinへのゲーム機能の割り付けは下表のようにしました。
Shifterの各スイッチは普通のdegital inputです。
Front Wiperスイッチはレバーの倒れによってRetarderの増減を実現するため、現在の位置とひとつ前の位置を比較します。レバーが増加方向に動いたのか、減少方向に動いたのかを現在とひとつ前の位置によって判断し、それに応じた処理を行います。
E/Gブレーキに割り振ったRear Wiperスイッチについても同様な処理をしています。
FrontのMistとRearのWash+ONは指を離せば元に戻るタイプのスイッチです。これを利用して、増(inc+1)を繰り返しできるようにスケッチを書きました。
