HI,
I'am a new user and have been trying to configure the PWM modual on my tm4c123gh6pm board using CCS Version 5. If I start with an example project, I am able to build the entirety with no problem. When I use some sample code which I found, I encounter what appears to be linking errors in the include statements, I have tried going project-properties-ARM Compiler-includes, and searching my computer to find the correct files, then adding the link to include path. This gets rid of the errors within the code but still gives me a link error. I also checked the linked resources, based upon a source, and was missing TIVAWARE_INSTALL which did not fix any errors. Under advanced options I was missing the Pre-defines PART_TM4C123GH6PM and TARGET_IS_BLIZZARD_RB1 using the same source above. I do not believe the code to be the error but I have pasted it, and the errors I am receiving below. Thank you for your help.
