3.3 RUNNING THE EXAMPLE APPLICATION

The starter kit executes in either real-time (Run) or steps (Step Into, Step Over, Ani-

mate.) Real-time execution occurs when you select Run in MPLAB IDE. Once the

device code is halted, either by Halt or a breakpoint, you can step.

The following toolbar buttons can be used for quick access to commonly used debug

operations:

To see how these options function, do the following:

1. Select Debugger>Reset>Processor Reset

or click the Reset button to reset the

program.

2. Select Debugger>Run

or click the Run button. Observe how the application

operates.

3. Select Debugger>Halt

or click the Halt button to stop the program execution. A

green solid arrow will mark the line of code in the File window where the program

halted.

4. Select Debugger>Step Into

or click the Step Into button to step the program exe-

cution once. The green solid arrow will move down one line of code in the File

window. Click the button several times to step through some code.

5. Select Debugger>Reset>Processor Reset

click the Reset button to reset the

program again. The arrow will disappear, meaning the device is reset.

3.4 DEBUGGING THE EXAMPLE APPLICATION

For the example code given, everything works fine. However, when you are developing

code, it will likely not work the first time and need to be debugged. MPLAB IDE provides

an editor and several debug features such as breakpoints and Watch windows to aid

in application code debugging.

This section includes:

• Editing Application Code

• Using Breakpoints and Mouseovers

• Using Watch Windows
