Remove the breakpoint from the
irq_counter++;
line, and put a breakpoint inside
the conditional statement that increments
sticks
, at the line
sticks = 0;
Press Run
to run and halt at this breakpoint. The window should look like this:
FIGURE 3-11:
MEASURE INTERRUPT PERIOD
The Stopwatch Time window shows 1.0012346 seconds, which is close to a one
second interrupt. A good time measurement would be to measure the time to the next
interrupt. That value could then be subtracted from the current time. Or, since it doesn’t
matter how much time it took to get here – the main interest is the time between
interrupts – press Zero on the Stopwatch and then press Run.
3.5
EXPLORING FURTHER
Measure the overhead of the interrupt, calculate how this will affect the timing, and try
to adjust the constant TMR1_Period to adjust the interrupt to get better 1 second
accuracy.
What is the maximum time (in minutes) measured by this routine What can be done
to extend it
Add a routine that outputs a two millisecond pulse every second from a port. Verify the
pulse duration with the stopwatch.
Note:
The Stopwatch always tracks total time in the windows on the right side of
the dialog. The left windows can be used to time individual measurements.
Pressing zero will not cause the total time to change.
