http://ru.aliexpress.com/item/ForAr...For-UNO-R3/1949318944.html?detailNewVersion=2 купил такой дисплей пробую запускать видно как пиксели немного темнеют при старте ардуины затем все пропадает изображения нет может кто помочь с запуском ?
Смогут, если будет больше информации. 1. Какой контроллер в дисплее 2. Какой библиотекой пользуешься 3. Выложи тестовый скетч 4. На каком МК запускаешь дисплей
http://forum.banggood.com/forum-topic-93683.html Вот здесь библиотека с семплами лежит для вашего экранчика на чипе ILI9335.

Вы в fritzing нарисуйте схему. И скетч в специальное место. 95% даю, что у Вас просто где-то неконтакт!
