Yasushi TAUCHI / Mbed 2 deprecated BlueUSB_f

スマートコンセント　PS-5204PSをmbedで

Dependencies:   FatFileSystemCpp mbed TextLCD

Fork of BlueUSB by Peter Barrett

Fusjitsu　スマートコンセント　FX-5204PSを利用できます。

BlueUSBを利用していますが、Bluetoothは兼用できません。

複数台利用するには、USBハブを使用してください。ただし相性があります。
・良ければ10台まで利用できるかも。
・稼働中に追加はできますが、外すことはできません。



LED1-3,　スマートコンセント接続状態(3台まで表示）
LED4、点滅で正常動作
