Z-Uno Buttons Library

Library implements high-level API for tact and capacitive buttons. Button sets are supported. Library is able to operate with any GPIO-pins, but for some extra functionality like interrupt mode BtnButtonModeExtInt there are some hardware restrictions. Please read the details in the description of addButton method.

Note that Buttons library uses 2 DMA channels in case of capacitive button support.
