How to Work on Variables

Microcontrollers Debugger Manual

Modify a Variable Value

The Debugger allows you to change the value of a variable, as shown in 

Figure 6.3

.

Figure 6.3  Modifying a Variable Value

Double-click on a variable. The current variable value is highlighted and can be edited.

1. Formats for the input value follow the rule from ANSI C constant values (prefixed by 

0x for hexadecimal value, prefixed by 0 for octal values, otherwise considered as 
decimal value). For example, if the data component is in decimal format and if a 
variable input value is 0x20, the variable is initialized with 32. If a variable input value 
is 020, the variable is initialized with 16.

2. To validate the input value you can either press the 

Enter

 or 

Tab

 key.

3. If an input value has been validated by the 

Tab

 key, the value of the next variable in 

the component is automatically highlighted (this value can also be edited).

4. To restore the previous variable value, press the 

Esc

 key or select another variable.

A local variable can be modified when the application is stopped. Since these variables are 
located on the stack, they do not exist as long as the function where they are defined is not 
active.

Get the Address Where a Variable is 
Allocated

The Debugger provides you with the start address and size of a variable if you do the 
following:

1. Point to a variable name in a Data Component

2. Click the variable name

The start address and size of the selected variable is displayed in the Data info bar.
