* how to use the FreeRTOS API. In addition to the standard demo tasks, the
* following tasks and tests are defined and/or created within this file:
*
* Webserver ("uIP") task - This serves a number of dynamically generated WEB
* pages to a standard WEB browser. The IP and MAC addresses are configured by
* constants defined at the bottom of FreeRTOSConfig.h. Use either a standard
* Ethernet cable to connect through a hug, or a cross over (point to point)
* cable to connect directly. Ensure the IP address used is compatible with the
* IP address of the machine running the browser - the easiest way to achieve
* this is to ensure the first three octets of the IP addresses are the same.
*
* "Reg test" tasks - These fill the registers with known values, then check
* that each register still contains its expected value. Each task uses
* different values. The tasks run with very low priority so get preempted very

* *NOTE 6* vSetupClockForRunTimeStats() is called by the kernel (via the
* portCONFIGURE_TIMER_FOR_RUN_TIME_STATS()) macro to configure an MTU channel
* to produce a time base that is used to log how much processor time each task
* is consuming. The MTU is used to generate a high(ish) frequency interrupt,
* and so also provides an example of how interrupts that don't make use of the
* FreeRTOS kernel can be assigned a priority above any priority used by the
* kernel itself.
