Kansai Electric Power usage meter (Denki-yohou)

Dependencies:   mbed mbed-rtos EthernetInterface

関西電力 でんき予報メーター

関電のでんき予報のリアルタイム値（使用電力状況データ CSV ）をもとに、mbedのLEDを点灯させます。

Kansai Electric Power usage meter (Denki-yohou)

Last commit 03 Jul 2012 by Suga koubou

  • LED1 動作中表示
  • LED2 70%以上
  • LED3 85%以上
  • LED4 95%以上

新しい Ethernet Interface ライブラリと、独自の Tiny HTTP クライアント ライブラリを使っています。

CSVの解析処理をはしょって改行を頼りにしているので、CSVファイルの構造が変わるとうまく動かなくなります。
東電でも同様に使えると思います。
