USB HID Keyboard Device (usb_dev_keyboard)

+//! +//! This example application turns the evaluation board into a USB keyboard +//! supporting the Human Interface Device class. The color LCD display shows a +//! virtual keyboard and taps on the touchscreen will send appropriate key +//! usage codes back to the USB host. Modifier keys (Shift, Ctrl and Alt) are +//! ``sticky'' and tapping them toggles their state. The board status LED is +//! used to indicate the current Caps Lock state and is updated in response to +//! pressing the ``Caps'' key on the virtual keyboard or any other keyboard +//! attached to the same USB host system. +//! +//! The device implemented by this application also supports USB remote wakeup +//! allowing it to request the host to reactivate a suspended bus. If the bus +//! is suspended (as indicated on the application display), touching the +//! display will request a remote wakeup assuming the host has not +//! specifically disabled such requests. +// +//***************************************************************************** + +//***************************************************************************** +// +// Notes about the virtual keyboard definition +// +// The virtual keyboard is defined in terms of rows of keys. Each row of +// keys may be either a normal alphanumeric row in which all keys are the +// same size and handled in exactly the say way, or a row of "special keys" +// which may have different widths and which have a handler function defined +// for each key. In the definition used here, g_psKeyboard[] contains 6 rows +// and defines the keyboard at the top level. +// +// The keyboard can be in 1 of 4 states defined by the current shift and +// caps lock state.
