Could not open source file "DSP2833x_Device.h"

My assumption is that the path described to the C compiler to look for header files is not accurate to allow the C compiler to find the DSP2833x_Device.h file.

You should review the compiler include path via the Project build properties and ensure the path(s) are added that will lead to this above file on your PC's hard drive.

Also, if you perform a search on the phase "could not open source file" in the E2E forum search box, you will find a number of posts that suggest similar courses of action.

Dear BrandonAzbell,

thank you for your response.

First I want to add information that when compiling the tutorial says that I have to include 2 search paths;

1. C:\tidcs\C28\DSP2833x\v131\DSP2833x_headers\include;

2. C:\tidcs\C28\DSP2833x\v131\DSP2833x_common\include;

I have seen again and when click open file dependencies option, realized there are 2 .h files which could not be opened; DSP2833x_Device.h and DSP2833x_example.h. I have check physically n found that both 2 .h files is physically existed in my include search paths

1. DSP2833x_Device.h is in C:\tidcs\C28\DSP2833x\v131\DSP2833x_headers\include

2. DSP2833x_example.h is in C:\tidcs\C28\DSP2833x\v131\DSP2833x_common\include

But why Code Composer can not find it?

The error messagese in the compiler output appears to have whitespaces between various directory levels.  For example:

-i"C:/ tidcs / c28 / dsp2833x/ v131/ DSP2833x_common/ include"

This seems very strange and I wonder if this is a cause of the issues you are seeing.  Would you retype these paths to ensure there are no whitespaces?
