3.2.3.1.2.4 Debug Environment Windows

It is standard debug practice to watch local and global variables while debugging code. There are various methods for doing this in CCS, such as memory windows and watch windows. Additionally, CCS has the ability to make time (and frequency) domain plots, which allows the user to view waveforms using graph windows.

1. Populate the Expressions Window entries by clicking View > Scripting console on the menu bar and then opening thesetupdebugenv_lab1.js file from the project directory using the scripting console Open File ( ) command. The Expressions Window should look like Figure 24.
