There are two simple CAN projects in the attached .zip file.

Hi Bob Crosby,
While compiling , I am getting this error, what might be the reason ?

The error is that the linker cannot find the TivaWare library "driverlib.lib". Do you have TivaWare installed? If yes, is it installed in a different directory than the default c:\ti ?

If you have TivaWare installed in a different location, right click on the project name in the project explorer and select "Show Build Settings...". Then expand the menus to show the ARM Linker, File Search Path page. You can then edit the path to the library file using the edit button that I highlighted in the image below.

Yes, I have installed in this directory only.

Using Windows Explorer, can you verify that the driverlib.lib file is correct?

Yes

Sorry, Now only I noticed the change in version of tivaware, version which I use is "TivaWare_C_Series-2.1.3.156". I updated it to new version and now its compiling without error.

Thank you

I suspect that the simple CAN examples will work with the older version of TivaWare, but it is best to download and start using the new version as there are some bug fixes. Both versions can reside on your PC.
