GPIO на python3

Oleg_Morozov · 18.Март.2021 11:37:58

я пробую согласно инструкции установить библиотеку python для работы с gpio портами. Смотрел и качал от сюда GitHub - wirenboard/wb-io-python: Generic IO Python Library. На python2.7 нет проблем с установкой и пользованием. Python3 не видит установленную библиотеку, а при попытке установить библиотеку “python3 install …” выдает море ошибок. Есть ли решение или способ управлять портами gpio без библиотеки?

добрый день! Рекомендуемый способ работы с дискретными входами и выходами в Wiren Board - это MQTT.

Ещё можно попробовать gpiod · PyPI , хотя вам придётся парсить номера и смещения gpiochip самостоятельно.

Если расскажете подробно, что значит

, то попробуем помочь и с wb-io-python

Как в библиотеке PRI.GPIO, так что она должна хотябы видна питону 3?
Возможно ли перемещение папки библиотеки в иную директорию или директорию проекта для хотя бы нахождения её программой?

Вывод терминала при установке библиотеки
