6.5. Enabling and Using Watch Windows
The Debug Windows in the View menu are used to view and modify hardware registers. To view and modify
variables in code, the IDE provides Watch Windows. Just as with register debug windows, variables in the watch
windows are updated each time the device is halted. This section of the User’s Guide explains how to add a
variable to the watch window and modify the variable. In the F330_FeatureDemo example code, the variable
Num_LED_Flashes is a counter that stores the number of times the LED blinks.
1. If the device is running, stop execution using the “Stop” button or use the Debug → Stop menu option.
2. In the File View on the left-hand side of the IDE, double-click on F330DC_FeaturesDemo.c to open the source
3. Scroll to the Timer3_ISR function (line 334) and right-click on the variable “Num_LED_Flashes”. In the context
4. Start and stop the device a few times. See that the value of the Num_LED_Flashes is incremented each time
5. When the device is halted, click on the value field in the watch window and change the value to 0. Then click the
6. Start and stop the device a few times to watch the variable increment starting at 0.
Changing the values of variables does not require recompiling the code and redownloading the firmware. At any
time, the device can be halted and the values of the variables can be changed. The firmware will continue
execution using the new values.
