The CMX CMXTracker provides the user
the ability to log chronologically in real-time, the tasks' execution
flow, capturing when a task is executing, the CMX functions
called and their parameters, interrupts using CMX functions
and the CMX system TICK within the CMX-RTX Real-Time Multitasking Operating System environment,
while the user's application code is running.
Displaying of the log is performed by CMXTracker which
runs as a task, usually being the highest priority task. In most
cases, one of the target processor UART channel(s) is used
as the input/output device. A simple terminal or CPU with a keyboard
is all that is required to use CMXTracker.
When the user enables the CMXTracker task, it will send
a menu to the screen. The user may then select one of many prompts,
allowing the user to view the chronologically ordered log, reset
the log, resume running of application code and possibly change
some aspects of the log, such as "autowake" CMXTracker
after a certain number of entries. When the CMXTracker
task is running, it prohibits other tasks from running, stopping
the task timers and cyclic timers and also disables interrupts
from calling the CMX functions, so as the application code
will "freeze" within the CMX RTOS environment.
CMXTracker allows the user to view the log at the beginning
or end, paging down or up, viewing the exact execution of the
tasks. Also what CMX functions were called with their parameters
and results returned (such as the message sent or received, event
bits set, timed out, etc.) and interrupts, with the CMX
system TICK being a "timeline" stamp.
CMXTracker allows the user to "single step"
one system TICK, thus allowing normal activity to occur
for one system TICK, with CMXTracker resuming after
this "single step". The user can also set the desired
number of system TICKS that CMXTracker will wait,
allowing normal activity, before it again resumes. This is a very
powerful and helpful feature.
CMXTracker is now available for use with the CMX CMX-RTX package,
for most processors and vendors that CMX supports. All
source code is included.
