I own 2 development boards and wish to experiment with them.. They came with Keil uV4 software. I inquired about a full License and was told by Keil $6800 for 1 year. Does anyone have a more economical solution? I don't have a lot of money and just want to experiment with example software at first them attempt to write some of my own stuff once I get comfortable with the programming environment.

is CCS a better cheaper solution or is there some others? I'm graduating from the free Arduino world and looking for similar programming capability yet at affordable prices.

Any help or suggestions is appreciated as I'm new the this Cortex ARM environment.

Bob

Thankyou

    The free version of Keil should be just fine for that!

    Similarly IAR.

    That sounds like the top-of-the-range, all-bells-and-whistles price - did you ask them about the other versions?

    CCS is free & unlimited when used with a TI board: http://processors.wiki.ti.com/index.php/Stellaris_support_in_CCS#What_CCS_License_types_support_Stellaris.3F

    It is possible to build a "free" (sic) toolchain from open-source components - but that very much depends on you having the wherewithall to collect and put it all together. IMO, that's not a beginner's option.

    A Red Suite Full Licence from Code Red Technologies supports Stellaris: http://www.code-red-tech.com/products.php

    Agree 100% w/above poster - and encourage you to download the "free - unlimited time versions" of both Keil and IAR.  Believe that in both cases you can debug and program up to 32KB - with minimal loss when compared to the "paid" version.

    Beware - know that IAR also offers a, "time-limited - code size unlimited" version.  Forgive me - but, "Avoid this like the plague!"  (strong msg to follow)  Even if you far exceed our group's "dull normal" status - you will not be ready for a time-limited incarnation - and haste - especially in MCU development - too often makes waste.  Later - after you've mastered the basics - is the time to try time-limited.  (and that time will pass in an instant...)

    Unsaid (and perhaps unwelcome here) is that Keil & IAR (possibly others) accept a variety of ARM and non-ARM MCUs - you are not limited to "one" MCU vendor.  Choice is important - especially when cost and availability issues litter the landscape...

    BTW - your boards may have come w/one "flavor" IDE - but most always there is no "lock" forcing you to use only that.  Now is an excellent time to experiment - see which one best suits.  In our case we purchased multiple "seats" of 256KB IAR - far less costly than what you quoted. 

    Apart from IDEs - the SW-DRL-UG and your MCU datasheet (some 1400+ pgs.) will prove immensely helpful.  Also read/review many code examples - especially those which came with your Eval Board. 

    Many new users attempt to create their own, "Unique Projects."  Don't!  Heartbreak lurks around that corner - instead choose an existing project as close as possible to your needs - copy/safely save the original project - and then "add" your elements to the "known working" project.  (just forum search for, "Create Own Project" - reads like review of SS Titanic by those who survived...)   Bon chance...

    your boards may have come w/one "flavor" IDE ...

    The various options are listed here: http://www.ti.com/tool/ek-lm4f232

    • Keil
    • IAR
    • Sourcery CodeBench
    • Code Composer Studio

    ... but most always there is no "lock" forcing you to use only that

    Indeed!  And you can download the images of the CDs which accompany each variant - so you can try them all!

    The possible exception is CCS - it might be best to speak to your local FAE/Distributor/Sales office for clarification of CCS licence...

    Note emphasis!!

    The advantage of sticking with the "supported" toolsets (above) is that they are, well - supported! ie, you get specific documentation & examples relevant to those particular tools.

    I beleive that the Keil 256K version would be far less than quoted - but did you also get a "deal" for buying multiple...?

    But of course, mon ami - but of course...

  • Bob:

    I am using CCSV5 -- I am quite happy with it now and would recommend it if you need the large program sizes. Some experience with Eclipse for Android or GCC make it easier -- but it can be done...

    See here for additional videos -- related to the launchpad LM4F120XL -- but should be applicable to the "big brother".

    http://processors.wiki.ti.com/index.php/Getting_Started_with_the_Stellaris_EK-LM4F120XL_LaunchPad_Workshop?DCMP=stellaris-launchpad&HQS=stellaris-launchpadtraining

    CCSV5 with the latest Stellarisware is a true bargain -- free! Dig around for free courses and workshops on the TI site. They will get you started.

    And also with local distributors, tool vendors, etc,...

    And, of course, ARM themselves: http://www.arm.com/ - check out the "Community"...
