@ -66,6 +67,14 @@
* 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
@ -87,9 +96,12 @@
* "High frequency timer test" - A high frequency periodic interrupt is
* generated using a timer - the interrupt is assigned a priority above
* configMAX_SYSCALL_INTERRUPT_PRIORITY so should not be effected by anything
* the kernel is doing. The interrupt service routine measures the number of
* counts a separate timer performs between each interrupt to determine the
* jitter in the interrupt timing.
* the kernel is doing. The frequency and priority of the interrupt, in
* combination with other standard tests executed in this demo, should result
* in interrupts nesting at least 3 and probably 4 deep. This test is only
* included in build configurations that have the optimiser switched on. In
* optimised builds the count of high frequency ticks is used as the time base
* for the run time stats.
*
* *NOTE 1* If LED5 is toggling every 5 seconds then all the demo application
* tasks are executing as expected and no errors have been reported in any
