Не удается успешно запустить приложения Kivy на Raspberry Pi 3 с 3.5 на сенсорном экране

Не удается успешно запустить приложения Kivy на Raspberry Pi 3 с 3.5 на сенсорном экране

Я следовал всем инструкциям по установке Kivy для Raspberry Pi.

Мой сенсорный экран работает совершенно нормально, я не думаю, что Kivy не запускается должным образом, как-то связано с этим.

Попытка запустить различные демоверсии Kivy приведет к тому, что будет казаться, что это частичный запуск, но затем он просто зависнет.... возможно, мой config.ini настроен неправильно?

Например, запуск 'python main.py' для примеров / demo / pictures / дает мне:

А потом просто висит навсегда. Ни одно окно не появляется, ничего.

То же самое происходит при работе с сенсорного экрана, через SSH и через удаленный рабочий стол thinvncserver.

Обновление: нет хороших новостей, но некоторые подробности. Бег python main.py -c kivy:log_level:trace с помощью простого приложения ( https://kivy.org/docs/guide/basic.html) с прерыванием клавиатуры:

На мой взгляд, это либо отсутствующий модуль ffpyplayer, либо что-то связанное с EGL.

Обновление 2: Ну, я перезапустил базовое приложение в моей Windows Kivy, чтобы сравнить журнал (приложение успешно запускается в моей Windows Kivy). Ошибка ffplayer все еще существует, что заставляет меня поверить, что это какая-то проблема EGL.

В настоящее время я сталкиваюсь с той же проблемой с 10,1-дюймовым емкостным сенсорным экраном Eleduino. Мне удалось решить проблему с настройкой файла: ~/.kivy/config.ini Перейдите в раздел [input] и прокомментируйте все. Затем добавьте следующие строки:

    test = mtdev,/dev/input/event3
    ntrig = mtdev,/dev/input/event1

Может быть, этот учебник поможет вам. Он использует тот же контроллер, что и вы (ADS7846). Просто пропустите часть GPIO. Есть часть где раздел [input] в файле ~/.kivy/config.ini меняется:

mouse = mouse
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput
