1. Steps to work with CCS
2. Program and Result
2
Open project
Add header files
Add source files
Add command files
Compile the program
Compile the program
Create data files
Create the probe point
Run the program
Load/Reload program

 Open the menu project
->Build Options
 Select the Compiler tab
 Select pre-processor
 In the Include Search
Path then
add the directory path to
the location of project.
Fig 2. The steps to add the
includes files to the project’s
directory

 Open the menu: Project>Build Options
 Select the Linker tab and
then Select Basic
 In the Library Search Path,
add the directory path to the
location of project.
Fig 3. The steps to add the
command files to the project’s
directory

Add data file
Add probe point
Fig 4. Add the data file

The steps to work with this example to show as follows:
 The program “Example_281xEvPwm.c”
 Select File -> Load Gel ( General Extension Language File) -> Open the
Example_281xEvPwm.gel
 From the Gel Tab -> Load and build project -> This will load the
project and build compile the project
From the Gel Tab -> Load code -> This will load the .out file into the
28x device, populate the watch window with variables of interest, reset
the part and execute code to the start of the main function.
Use probe point to create and watch the output signal with Eyes
Diagram
Use the osciloscope to check the output signal at the PWM pins
