python tkinter、センサ値はリフレッシュされません

Question

こんにちは、私は私のpython guiアプリケーションでいくつかの問題を抱えています、私はセンサーのモードボタンをクリックする以外のアプリはうまく動作します。値 "m"は、gui - appが最初にロードされ、更新されないときと同じままです。私は過去1ヶ月のtkinterの使用を始めました。私はwhileループやそれに類するものを実装する方法を理解するのに苦労しています。私はメインの中にループを配置し、それが終わったときにアプリケーションを再オープンするだけです。アプリは私のraspberryPiで作成されたので、gpioとraspberrypiのすべてのものをコメントアウトして、PC上で動作します。アプリは基本的に2モードタイマーモードとセンサーモードですが、値 "センサー"が50％以下になると関数を入れませんでしたが、私はすでに別のセンサープログラムを持っています更新するセンサー。

一部のアプリセンサーの値m - mpc3008が常に更新されるようにアプリを修正してください。
