Scan buttons for presses through a shift register


Get the status of buttons pressed since the last call and clear it.

Returns an 8-bit number, with bits that correspond to buttons, which have been pressed (or held down) since the last call to this function set to 1, and the remaining bits set to 0. Then it clears the button state, so that new button presses (or buttons that are held down) can be recorded for the next call.


Disable button scanning.
