Airio-Baseで 6軸センサーデータ取得とSDカードへの記録をするサンプルコードです。

準備

SWスイッチ動作

SWを押している間、LED2が点灯します。それ以外はなにもありません。

ISPスイッチ動作

SDカードにアクセスしカレントディレクトリに「TEST.txt」を作成し 6軸センサーからデータを0.4秒ごと5回のデータを取得して記録します。動作中LED1が点滅します。

取得データの確認

データの取得と記録が成功すると、以下のようなテキストデータがFlashAir等(SDカード)内に記録されます。複数回してもデータは上書きされます。FlashAirはAirio-Baseに装着のまま、PCやスマートフォンからFlashAirにアクセスし確認してみて下さい。
