TODO check out Arduino vs. Maple static discilpline cutoffs to -.. ensure accuracy of following: - -The libmaple implementation of ``pinMode()`` supports the ``INPUT`` -and ``OUTPUT`` modes with semantics identical to that of the Arduino -function (however, be advised that the Maple, as a 3.3V device, will -only drive 3.3V to an ``OUTPUT`` pin that has been set ``HIGH``). - -``INPUT_ANALOG`` and ``PWM`` modes were added because the Maple does -not distinguish between analog and digital pins the same way the -Arduino does. Unlike the Arduino, you **must call** ``pinMode()`` to -set up a pin for these purposes before a call to, e.g., -:ref:`lang-analogRead`. In practice, this should only add a few lines -to your :ref:`lang-setup` function. - -..
