The following table describes each of the buttons in the Debugger toolbar.

View Breakpoint

List

Toggles the breakpoint list pane. See

Setting and Using Breakpoints

later in this chapter for more information.

View Watch List

Toggles the watch list pane. See

Using the Watch List Pane later in this

chapter for more information.

View Call Stack

Toggles the call stack pane. See

Using the Call Stack later in this

chapter for more information.

Resume

Resumes execution of a halted application. See

Stopping an Application

later in this chapter for more information.

Halt

Halts the application running on the current device. See

Stopping an

Application later in this chapter for more information.

Reset

Resets the current device.

Stop

Stops debugging the current device.

Watch Variable

Opens the Add to Watch List dialog. See

Using the Watch List Pane

later in this chapter for more information.

Toggle Breakpoint

Toggles whether the current line of code has a breakpoint. See

Setting

and Using Breakpoints later in this chapter for more information

Step Over

Executes the current line of the application. If the current line contains a

function, the function will execute in its entirety. See

Stepping Through

Applications later in this chapter for more information.

Step Into

Executes the current line of the application. If the current line contains a

function, the application will halt at the first line of the function. See

Stepping Through Applications later in this chapter for more information.

Run to Cursor

Sets an implicit breakpoint at the line that the cursor is on. The

application resumes if it is currently halted and continues to execute if it

is already running. The application will halt when it reaches this implicit

breakpoint. In addition, the breakpoint will be cleared once it is

encountered.

Current

Instruction Source

Code

When the application is halted, jumps to the line of code on which the

application has halted.

Stopping an Application

You can stop an application while it is running in debug mode in three ways: halting the application,

running to the cursor, and setting breakpoints.

Once you stop an application, you can step through the application one command at a time (see

Stepping Through Applications for more information), observe the values of variables in the watch list

(see

Using the Watch List Pane for more information), and observe the condition of the call stack (see

Using the Call Stack for more information).

To resume execution of an application that you have halted, either click the resume button (

) on the

Debugger toolbar, type <F5>, or select Go from the Debug menu. The application will continue

running until it hits another breakpoint (or the same one again). You can also move your cursor and

click the run to cursor button to have the application resume execution until it gets to the line

containing the cursor.

The following sections describe the three methods for stopping a device application running in debug

mode.
