Tutorial 2 - Real-Time Interrupt
2003 Microchip Technology Inc.
DS70094B-page 39
In order to see that the interrupt seems to be working as designed, remove the break-
point at
main_counter++
by clicking on the highlighted line with the right mouse but-
ton and select Remove Breakpoint. Now select Enable Breakpoint in the right mouse
menu to put a breakpoint in the interrupt service routine at the
irq_counter++
state-
ment, then press Run. The Stopwatch should look like this:
FIGURE 3-9:
STOPWATCH AT FIRST INTERRUPT
The value shown in the Time window is 1.0304 ms. This is about what was expected,
since the interrupt should happen every millisecond. There was some time since
RESET that was counted by the Stopwatch, including the C start-up code and the Timer
1 initialization.
Look at the Watch window. The variable
main_counter
is showing a value of 0x3E8.
Change the radix of this display to decimal by placing the cursor over
main_counter
in the Watch window, using the right mouse button, choose “Properties”. A dialog will
be displayed. Go to the Format pull-down and select Decimal, then press OK.
FIGURE 3-10:
SET WATCH RADIX
The
main_counter
value should now show 1000. Press the Step-Into icon a few more
times to see the changing variables, especially
sticks
and
irq_counter
, which are
incrementing each time the interrupt happens.
