Залил подправленный скетч. Стартовый экран высвечивается и стоит как вкопанный :thinking:

86

Почитал. Интересно, но как применить, что и куда вписать? Если знаете, подскажите. :face_with_monocle:

87

Вам даже в скетче вписали - см. последний код от @BOOM

Не верю.

С подправленным скетчем, картина именно такая. Заставка и всё :thinking:

Понимание может и есть, нет опыта применения. Это важно.

92

Нет понимания. Иначе прочитанное, да в купе с приведенными там же примерами, вопросов бы не вызвало :wink:

Петрович сказал что два дня до полнолуния и всякая “ерунда” может твориться.
Может просто подождать? :smiley:

94

Покажи вывод ИДЕ (“Скетч использует столько-то из стольки то и тпт”) и что за плату выбираешь при компиляции (какая плата физически установлена?)?

95

В программировании, много разного рода факторов, которые влияют на конечный результат. По этому и существует “ОТЛАДКА”. А в целом, если хочется реально помочь, сваяй несколько строк, как альтернативу, для заставки и укажи, куда её вписать правильно, что бы она работала правильно. :slightly_smiling_face:

Вот СкринШоты, установленных, обновленных библиотек.

Переустановка библиотек, на более ранние, включая “первые” релизы библиотек, результата не дал. Всё так же. Заставка выводится и всё.
Информация об успешной компиляции (это “базовый”, рабочий скетч, которым я использую).

В информационном поле отображается следующая информация (полностью не вошла в скриншот).
“Скетч использует 27524 байт (92%) памяти устройства. Всего доступно 29696 байт.
Глобальные переменные используют 580 байт (28%) динамической памяти, оставляя 1468 байт для локальных переменных. Максимум: 2048 байт.”
Это ваш, подправленный(!) скетч. То же компилируется и заливается.

Выводная информация.
“Скетч использует 27426 байт (92%) памяти устройства. Всего доступно 29696 байт.
Глобальные переменные используют 602 байт (29%) динамической памяти, оставляя 1446 байт для локальных переменных. Максимум: 2048 байт.”
Автор же не зря вписал комментарий в строку
“statup_text(); //If you hang on startup, comment”
Значит столкнулся, на этапе отладки с такой проблемой и не стал её устранять, а просто предупредил, что делать, если произойдёт зависание. Может исключить авторские строки заставки и организовать их как то иначе, всё равно скетч уже частично переработан? Но как это сделать правильно? :thinking:

Уже бежать исполнять?
