    Andy Neil
    BrandonAzbell I would suggest starting with Keil's website for information on the tool chain itself. http://www.keil.com/ Absolutely! that should really go without saying! In particular, see: http://www.keil.com/books/ and: http://www.keil.com/support/man/docs/gsac/

    Peter, From your prior post it looks like you have already downloaded StellarisWare. Open Keil and then open the project C:\StellarisWare\boards\ek-lm3s6965\timers\timers.uvproj (correct the path as needed if you did not install StellarisWare to the default location). That will give you a working...
