What is Tiva and TivaWare?

What was once Stellaris is now Tiva C-Series (the C stands for “Connected”).

In effect Stellaris->Tiva C-Series, StellarisWare->TivaWare.The old LM4Fxxx part numbers become TM4Cyyy, same chip, new name. The effect on your software is you will need to update the old Stellarisware C89 types to the new TivaWare C99 Types. There is a whole new Software Library install with new part headers (the LM4F->TM4C thing). This honestly shouldn’t effect anybody too hard, just keep using StellarisWare if you have been using it, update to the TivaWare if you get a Tiva Launchpad. Just be aware that the StellarisWare library is frozen, no new updates. All future updates will be under the TivaWare library.

Thats it folks, Stellaris is officially dead, long live Tiva.
