Library to use Arduino USB host shield on mbed
ArduinoのUSB Host Shield 2.0をmbedで使えるようにしたライブラリです。
大体のコードがArduinoからそのまま移植可能です。
Arduino UNOやMega用のホストシールド以外にもミニサイズのホストシールドでも使用可能です
シールドについて
3.3VのI/O用にシールドの改造が必要になりますがネット上に記事がたくさんあるのでそちらを参考にしてください
接続例
使い方
Arduinoのコードと違うのはUSBのインスタンスの宣言部分のみです。
ピンを自分で指定できるようにしたので使いやすくなりました。
仕様
- Arduinoのmillis関数、micros関数の移植のために内部でTimerクラスを使用しています。
