Создание библиотеки MBed, ошибка «ожидаемый идентификатор»

Question

Вот мой код. Когда я пытаюсь скомпилировать его, появляется ошибка «ожидаемый идентификатор», я полагаю, что это связано с тем, как я отформатировал инициирование Timer2.

Что мне нужно изменить, чтобы этот код мог компилироваться?

Большое спасибо.

При необходимости я могу добавить файл заголовка.

Answer 1

Ваш конструктор Timer2 имеет мошенник :, который используется, когда у вас есть списки инициализации (т.е. при вызове конструктора базового класса, или при установке значения членов класса). Поскольку в списке нет идентификаторов, вы получаете ошибку. Удалите двоеточие, и он должен работать.
