RTclock
is a structure, as indicated by the small plus symbol in the box to the left of
its name. Click on the box to expand the structure so it looks like this:
FIGURE 3-7:
WATCH STRUCTURE
Also add the variables
sticks
,
irq_counter
, and
main_counter
to the watch
window.
FIGURE 3-8:
WATCH VARIABLES
The Value column may be expanded wider in order to read the text on the
sticks
variable. Note that it says “Out of Scope.” This means, that unlike
RTclock
,
irq_counter
, and
main_counter
, this is not a global variable, and its value can only
be accessed while the function
_T1Interrupt()
is executing.
When inspecting the variables in the watch window at this first breakpoint, all of them
should be equal to zero. This is to be expected, since Timer 1 just got initialized and
counter
has not yet been incremented for the first time.
Press the Step-Into icon to step once around the
main()
loop. The value of
main_counter
should now show 0001. The interrupt routine has not yet fired.
Looking at the Stopwatch window, the elapsed time only increments by a microsecond
each time through the
main()
loop. To reach the first interrupt we’d have to step a
thousand times (1000 x 1 us = 1 ms).
Note:
The Address column for
sticks
does not have a value. This is another
indication that
sticks
is a local variable.
