SDカードがエラーなくロギングを停止するのはなぜですか？

Question

次のスケッチはArduino Nanoクローンのスケッチです。 STARTコマンドを待ち、I2Cスレーブからデータを収集し、SDカードに記録するために組み立て、カードに書き込み、シリアルモニタに出力して繰り返します。私はテストし、再テストしました。 SDカードのログファイルは、ヘッダと30行のデータのうち3行をロギングした後も常に停止しますが、シリアルモニタにはすべてのデータが表示されます。私のテストでSD書き込みエラーが発生したことはありませんでした。

SDがロギングを停止する理由と解決方法については、私は感謝しています。

問題を解決するには、することでしたSDカードをより速いものに交換してください。一度私はデータを記録しなければなりませんでした。パトリックが提案してくれてありがとう。
