Using the Watch Window with Structures

In addition to watching the value of a simple variable, you can watch the

values of the elements of a structure.

1) Right-click on the Watch Window area and choose Insert New

Expression from the pop-up list.

2) Type str as the Expression and click OK. A line that says +str = {...}

appears in the Watch Window. The + sign indicates that this is a structure.

Recall from section 2.3, page 2-4 that a structure of type PARMS was

declared globally and initialized in hello.c. The structure type is defined in

hello.h.

3) Click once on the + sign. Code Composer Studio expands this line to list

all the elements of the structure and their values. (The address shown for

Link may vary.)

4) Double-click on any element in the structure to open the Edit Variable

window for that element.

5) Change the value of the variable and click OK. Notice that the value

changes in the Watch Window. The value also changes color to indicate

that you have changed it manually.

6) Select the str variable in the Watch Window. Right-click in the Watch

Window and choose Remove Current Expression from the pop-up list.

Repeat this step for all expressions in the Watch Window.

7) Right-click on the Watch Window and choose Hide from the pop-up menu

to hide the window.

8) Choose Debug

→Breakpoints. In the Breakpoints tab, click Delete All and

then click OK.
