/*
 * This demo includes a (basic) USB mouse driver and a WEB server.  It is
 * targeted for the AT91SAM7X EK prototyping board which includes a small
 * joystick to provide the mouse inputs.  The WEB interface provides some basic
 * interactivity through the use of a check box to turn on and off an LED.
 *
 * main() creates the WEB server, USB, and a set of the standard demo tasks
 * before starting the scheduler.  See the online FreeRTOS.org documentation
 * for more information on the standard demo tasks.
 *
 * LEDs D1 to D3 are controlled by the standard 'flash' tasks - each will
 * toggle at a different fixed frequency.
 *
 * A tick hook function is used to monitor the standard demo tasks - with LED
 * D4 being used to indicate the system status.  D4 toggling every 5 seconds
 * indicates that all the standard demo tasks are executing without error.  The
 * toggle rate increasing to 500ms is indicative of an error having been found
 * in at least one demo task.
 *
 * See the online documentation page that accompanies this demo for full setup
 * and usage information.
