pythonとarduinoのインタフェース

Question

私たちはardiunoとpythonをインタフェースしています。異なる間隔でPythonからardiunoに信号を送る必要があります。データを送信してデータを受け取るためにループを使用していますループの中でPythonからのシグナルを得る。 しかし、ループを使わずにpythonからardiunoに信号を送るために、同じコードを使用したとき、うまくいきました。

Answer 1

あなたはSerial.endを（使用して、そこからデータを読み込んだ後のArduinoのシリアルポートを閉じている）されて使用してループ でそれを使用する方法ループ関数。 Serial.end（）ステートメントを削除/コメントすると、Arduinoのシリアルポートのデータが引き続き受信されます。

がhttps://www.arduino.cc/en/Serial/End

を参照してください。また、私は（それは私たちの生活が少し楽になります）あなたは、シリアル通信用のPythonでpyserialライブラリを使用していると信じて:)

それが動作するかどうか、私たちは知ってみましょう。
