//! This example application uses LEDs connected to GPIO pins to create a
//! ``roving eye'' display.  Port B0-B3 are driven in a sequential manner to
//! give the illusion of an eye looking back and forth.
//!
//! In order for this example to work properly, the ULED0 (JP22), ULED1 (JP23),
//! ULED2 (JP24), and ULED3 (JP25) jumpers must be installed on the board, and
//! the PB1 (JP1) jumper on the daughtercard must be set to pins 2 & 3.
