Приветствую! Проблема у меня с библиотекой для fdplayer mini(DFPlayer_Mini_Mp3.h). Использую стандартный пример DFPlayer_Simple, в ней есть строчка для вывода в монитор порта статус работы платы плеера(Serial.println(mp3_get_state());). В скетче ничего не трогалось, но проект не компилируется, жалуется на данную строчку, а мне для проекта нужно как раз считывать данные с платы плеера. Пробовал другие библиотеки для работы с этим модулем, увы они не запустили мой модуль, а библиотека DFPlayer_Mini_Mp3.h смогла его запустить.
