Complete code was attached above for your reference

Please expand and show us the contents of the 'Includes' folder in the Project Explorer.

Thank you for the reply.

I have expand the project "includes" folder and share the screenshot for your reference.

i have included the bellow path

E:\ti\c2000\C2000Ware_4_03_00_00\device_support\f2837xd\common\include

but sill getting the above error

i am getting the above error after including the mentioned path

In that case, I suggest to start again.

I imported the following example:

Then removed 'adc_ppb_delay_cpu01.c' then added your main.c. It compiled just fine.

i am not getting the above .c file.

from where i will get this .c file

should i create a new project again or i have to close the ccs and open again

You can have multiple projects open in the same instance of CCS.

File -> Import... -> CCS Projects -> Browse -> E:\ti\c2000\C2000Ware_4_03_00_00\device_support\f2837xd\examples\cpu1

Select the top example then click Finish.

why should i go for the examples?

the code that i have share with you was ours.

SMPL said:

why should i go for the examples?

Your problem is compilation. The example compiles OK so use this as the starting point.

SMPL said:

I'm saying replace the example code with your code.

after replacing my main.c file to the example file i am getting the above error

The screenshot doesn't show anything about the error.

this are errors i am getting

i am getting this error after compiling the example file

why i am getting error in "F237xD_DefaultISR.obj" as it is a example file

Because compilation of F237xD_DefaultISR.c fails. What does the compiler say about this failure in the Console window?
