ロギングが途中で止まる

[Yukuro]

詳細

• e343438 にてロギングを実装した
• 実行してから数秒経つとSDカードへの出力が止まる
• logfile.open() とlogfile.close()は時間がかるためLOG_INTERVAL_LIMITおきに実行している

• シリアル出力

考えられる原因

• logfileのbufferサイズが512byte(らしい)( https://forum.arduino.cc/index.php?topic=358224.0 )ので、それがいっぱいになっている
  • だが、bufferに入れているのはログの文字列 x LOG_INTERVAL_LIMIT分だけ

備考

• GNSSのデータをログに含めないと動く時間が増えるのでwhileで処理を止めているのが何か関係があるかもしれない...

ロギング機能は無くても離床/開放判定は動くので他の作業を優先する
