Akizuki 32x16 dot LED Matrix unit (K-03735) control library.

秋月電子の32×16ドットLEDマトリクス表示装置(K-03735)を制御するライブラリです。
バッファの内容をそのままLEDマトリクス装置に送ります。
LEDマトリクス表示装置は最大４台まで接続できるので、接続台数を必ず指定してください。（この台数でバッファのサイズを計算しています。）
行間表示は1msのdelayを入れています。パラメタで変更可能です。
このライブラリの呼び出し元は基本的にwhile()でループしてください。
初めてのライブラリなのでメンバ関数もドキュメントとかまだ最低限です。
おかしなところはぜひコメントをください。
