【変更内容】
- 出力ファイル名の変更
→マイクロSDカードに"GPSlog.jsn"というファイル名で
JSONフォーマットのログを出力する。
【既知のバグ】
- GPSからの取得データ値がおかしなことがある。
→あれこれ調べたけど、断念(^^;
【今後の予定】
- JSON形式のログをhttp POSTで
node.js+express+mongoDBで構築している
ログ収集サーバにuploadするスケッチを作成する。
→一応できたので、別に書いときます。 - コテコテコーディングからArduino_JSONを利用するように書き直し。
→変更してない。
http POSTするスケッチの中でちょっとだけ使用。 - ログ収集サーバ側では、JSON→GPX変換して、
googleMap等に表示できるようにする。
→まだ未着手。 - 同じくサーバサイドで、グラフ表示などの機能を作る。
生成したグラフは、Blogger上のこのブログに自動投稿させる。
→同じく未着手。
