* In addition to the standard demo tasks, the following tasks and tests are
|
||||
* defined and/or created within this file:
|
||||
*
|
||||
* "uIP" task - This is the task that handles the uIP stack. All TCP/IP
|
||||
* processing is performed in this task. It manages the WEB server functionality.
|
||||
*
|
||||
* "Check" task - This only executes every five seconds but has a high priority
|
||||
* to ensure it gets processor time. Its main function is to check that all the
|
||||
* standard demo tasks are still operational. While no errors have been
|
||||
* discovered the check task will toggle an LED every 5 seconds - the toggle
|
||||
* rate increasing to 500ms being a visual indication that at least one task has
|
||||
* reported unexpected behaviour.
|
||||
* standard demo tasks are still operational. An error found in any task will be
|
||||
* latched in the ulErrorCode variable for display through the WEB server (the
|
||||
* error code is displayed at the foot of the table that contains information on
|
||||
* the state of each task).
|
||||
*
|
||||
* "Reg test" tasks - These fill the registers with known values, then check
|
||||
* that each register still contains its expected value. Each task uses
