LM4F120 supported by CCS?

I have done extensive research before posting this question, but I still can't understand if it is possible to develop for the Stellaris LM4F120 LaunchPad evaluation kit using a *non-paid* version of CCS.  I would appreciate any help, pointers.  Thank you!

PS: I am on Win 7.

  • Hi Todd,

    my understanding is that a built in stellaris ICDI interface (which is on your board) will allow you to use our free license.    Should, for whatever reason that not be the case, you have an affordable option to use the free license by using an XDS100 with the board.

    I hope this helps!

  • Lisa, thank you so much.

    Re: XDS100 - I glanced at the link you provided as well as the wiki link, but that was not enough to understand what an XDS100 is!  Mind you, I am coming from a software background w/ electronics knowledge limited to being able to program Arduino (I understand pull-up resistors etc).  I would appreciate knowing more about XDS100 if you have the time.  Particularly helpful would be a straightforward explanation of what JTAG is.  Thanks again.

  • Hi Todd,

    the best thing to do might be to also consider online resources.   JTAG is a programming standard.  It is basically the standard/language used to program many chips (microcontorllers, DSPs etc).   Usually in order to program a chip you need an emulator which is a piece of hardware in between the computer and chip.   CCS allows you to tune some JTAG parameters, however to begin with of course I would not necessarily recommend doing that.

    Stellaris ICDI - this is an emulator on board.  It uses JTAG.

    XDS100 - this is an external, purchased emulator.  It also uses JTAG.

    Does this help?  As mentioned, I do not feel you will find you need an external emulator to use the free license.  In fact, have you tried that already?

    I would look up JTAG online and the links below.  Please keep us informed if we can further assist you.

    Best Regards,

  • Lisa,

    Thank you so much.  This was very helpful.  I will try CCS and report back here.

    Of the three links you posted, I was not aware of the TI Emulation (wiki) link, thank you for that.

    Regards,

  • Still trying to get Lab 2 to work.  Posted a separate question for that effort, will update this thread once I get past Lab 2.
