Мне пришлось написать код для измерения проводимости и расхода с помощью датчиков, подключенных к raspberry pi, и отображать и обновлять значение в графическом интерфейсе tkinter каждые 5 секунд.

Я получаю ошибку из-за платы импорта и GPIO.setmode (GPIO.ПЛАТА), используемая в той же программе.Точная ошибка, которую я получаю, — «Другой режим для платы уже установлен», помогите мне решить эту ошибку.

В качестве платы импорта и GPIO.setmode(GPIO.ПЛАТА) используется в той же программе, которая генерирует ошибку.Используйте метод GPIO.setmode (GPIO.BCM) для настройки платы для устранения ошибки.
