3.2.2.4.1.2 Setup Debug Environment Windows
  1. To add the variables in the Watch or Expressions window, click View → Scripting Console to open the scripting console dialog box. On the upper right corner of this console, click the Open button, then browse to the setupdebugenv_build1.js script file located inside the project folder. This script file populates the Watch window with appropriate variables needed to debug the system. Click the Continuous Refresh button (TIDA-010257 ) on the Watch window to enable continuous update of values from the controller. Figure 3-8 shows the Watch window.

  2. The current and voltage measurements can be verified by viewing the data in the graph window. These values are logged in the slower 10kHz routine. Go to Tools → Graph → DualTime, and click Import and point to the graph1.GraphProp file inside the project folder. This file populates the Graph Properties window. Alternatively, enter the values as shown in the Figure 3-9. When the entries are verified, click the OK button. Two graphs appear in CCS. Click the Continuous Refresh button (TIDA-010257 ) on these graphs. A second set of graphs can also be added by importing the graph2.GraphProp file.
