Yasushi TAUCHI / Mbed 2 deprecated BlueUSB_f_IEEE1888

スマートコンセント（富士通　FX-5204PS)をIEEE1888　StorageにWRITEするサンプルプログラムです。

Dependencies:   EthernetInterface FiapV2 HTTPClientForSOAP NTPClient TextLCD mbed-rtos mbed spxml

Fork of BlueUSB_f by Yasushi TAUCHI

スマートコンセント（富士通　FX-5204PS)をIEEE1888　StorageにWRITEするサンプルプログラムです。
USB　HUBを使用して2台利用した例です。
表示のみは http://mbed.org/users/yueee_yt/code/BlueUSB_f/で公開しています。

BlueUSBより派生していますが、BluetoothとMass Storage Classは利用できません。

2台まで確認していますが、プログラム的には10台まで接続できるようにしています。
（RTOSとの整合により難しいかもしれません）
