3.4.5.1 Setting Software Options for Lab 4

  1. Use the test setup shown in Figure 3-9.
  2. Open the CCS project as outlined in Section 3.2.1. If using the powerSUITE, go to Step 3, otherwise jump to Step 4.
  3. Open the SYSCONFIG page and select under the Build Options section:
    • Select Lab 4: Single Channel Closed-Loop CV for the Lab
    • Select Channel
    • Enable the SFRA
    • Save the page
  4. When using non-powerSuite version of the project, the above settings are directly modified in the solution_settings.h file.
    #define LAB_NUMBER (4)
#define CHANNEL_NUMBER (1)
#define SFRA_ENABLED (true)
