/*
* 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.
