Now you will set a breakpoint in the source code file window. Go to the main
loop of the program and click the right mouse button on the line movwf
PORTB. A menu will appear. Select Break Point(s). The line of code will
change color. If you don’t like this color, you may change it by selecting
Options > Environment Setup, clicking the Color tab and selecting a different
Color for Break Point Text.
Run the program by selecting Debug > Run > Run or by clicking the toolbar
green stoplight icon. The status bar on the bottom of the MPLAB IDE window
will change color, indicating that the program is running. The program will halt
when it reaches the breakpoint.
Single step by selecting Debug > Run > Step, by pressing <F7> or by clicking
the toolbar single step icon. You should now see that the value of PORTB in
the Watch_1 watch window has changed from H’00’ to H’FF’ and should
be a different color.
This demonstrates how breakpoints work with the ICEPIC In-Circuit Emulator.
The breakpoint halts an emulation run after the line of code it is associated
with is executed.
