3.2.2 Opening Project Inside CCS

There are three projects for F28002x, F28003x and F280013x separately, the projectspec file for F28002x based reference design is in the directory below<install_location>\solutions\tidm_02010_dmpfc\f28002x\ccs\sensorless_foc, the projectspec file for F28003x based reference design is in the directory below<install_location>\solutions\tidm_02010_dmpfc\f28003x\ccs\sensorless_foc, projectspec file for F280013x based reference design is in the directory below<install_location>\solutions\tidm_02010_dmpfc\f280013x\ccs\sensorless_foc

Import the project within CCS and select the right build configurations by right-clicking on project name as shown in Figure 3-3. Select the right build configuration for the HVAC reference design. The "HVAC_REV3P2_3SC_LIB" build configuration supports three-shunt current sensing method, the "HVAC_REV3P2_1SC_LIB" supports single-shunt current sensing method.

Configure the project to select the supporting functions in project by using either one of the following two ways:

  • Navigate to <install_location>\solutions\tidm_02010_dmpfc\f28002x\ccs\sensorless_foc for F28002x, <install_location>\solutions\tidm_02010_dmpfc\f28003x\ccs\sensorless_foc for F28003x, or <install_location>\solutions\tidm_02010_dmpfc\f280013x\ccs\sensorless_foc for F280013x. Open the project specs file with a text editor utility, select the right predefined symbols for the system as shown in Figure 3-4. The pre-define symbol is active or disabled by removing or adding the "_N" in the name. For example, enables field weakening control by removing the "_N" in "MOTOR1_FWC_N" to "MOTOR1_FWC", disables field weakening control functions for motor 1 (Compressor) by changing "MOTOR1_FWC" symbol name to "MOTOR1_FWC_N". After set the pre-define symbols in "tidm_02010_dmpfc_002x/003x/0013x.projectspec", import the project by clicking "Project → Import CCS Projects" to select the project based the hardware board in the related folder.
  • Click "Project → Import CCS Projects", and browse to <install_location>\solutions\tidm_02010_dmpfc\f28002x\ccs\sensorless_foc to import the project into CCS for F28002x based reference design or <install_location>\solutions\tidm_02010_dmpfc\f28003x\ccs\sensorless_foc for F28003x based reference design, or <install_location>\solutions\tidm_02010_dmpfc\f280013x\ccs\sensorless_foc for F280013x based reference design, and then right-click on the imported project name, click "Properties" command to set the pre-define symbols for the project as shown in Figure 3-5.
