Throws:

• IOException

_INSERT_METHOD_SIGNATURE_HERE_

Returns	Range	Description
state	0x00000000 ... 0xFFFFFFFF	every set bit represents an active input

The getKeyboardState() method returns the state of all keys asynchronously.

• When keyboard scanning is disabled, reading the keyboard state will always return 0x00 for all columns (see IO.enableDisableKeyboard(boolean)).
• Keyboard columns not having assigned a KeybCol # via iLCD Manager XEJoC Manager report all corresponding keys as not pressed.

Example

int[] button = IO.getKeyboardState();

if ((button[3] & (1 << 4)) == (1 << 4))

If this expression evaluates to true, in column #3, the button connecting to row #4 is pressed.

if ((button[3] & (1 << 2)) == 0)

If this expression evaluates to true, in column #3, the button connecting to row #2 is not pressed.
