New LM4F - Cortex M4 - Eval Boards - great!

Other Parts Discussed in Thread: LM3S6965

Greetings all:

TI today has formally announced new kits for Cortex M4 - we have this and another - they are terrific!  Suggest that you order quickly...

http://www.ti.com/tool/eki-lm4f232

  • What version of EWARM is available on the CD?

     

  • As stated - related post - we have paid version of IAR - paid no attention to that on CD.  Will check either later tonight or early tomorrow & report.

  • The IAR on the CD is the "KickStart" version 6.21

     

    Keep us posted on your experiences.

  • @Stellaris Dexter/interested others-

    Our group fortunate to receive 2 M4 kits - (dif't size MCUs).   First kit had "no" CD - instead all needed data was included on USB drive supplied w/kit.  Second kit - pictured above - supplied a "blank" USB drive - and a CD.  Usually - and many forum posts and TI responders note this - use of the supplied CD is "not" the best choice as newer material is available from the TI site.   Must report - that CD we received with this new kit is "best ever" - all material "very current" (8038DRL) and brand new, nicely organized write-ups and guides.  Now - everything in ONE Place! 

    This new M4F kit is extensive - well documented - should have something for everyone...  In this case users may wish to alter normal "rtfm" to "rtfcd" - really good stuff therein.

  • Thanks for the feedback!  I will pass it along to the team.

  • Hi,

     

     Is there a smaller version of evaluation board in a pipeline?

    This one physically doesn't fit my robotic platform.

    I have seen a video preview (with Miguel) showing a different LM4F... board.

    As well if possible to shrink the price as and make it closer to

    stm32f4discovery (<$20 - http://au.element14.com/jsp/search/productdetail.jsp?id=2009276&Ntt=stm32f4discovery).

    I know it's a cruel world and the competition is very strong. Keep up good job and don't give up.

    Surely -  heads will roll @ TI marketing!  ("how" could such a vast need be missed?)

    Forgive me - our group finds this 144 pin QFP M4F board most excellent in high-lighting the many features/capabilities of TI's new M4F.  Certainly the pcb could have been "stripped down" - but ease of use and multiple, extensive application solutions ("all" fully on board - btw) thankfully won out.  Full fledged, color GUI (albeit a small one), on-board 3 axis accelerometer, temp sensor, USB port, eased, real-world (to 20V) ADC quick connects and vast GPIO/PWM/Timers - each with well-defined, functional software - deliver an efficient, extremely broad user experience.

    We've seen/used board you've referenced - by the time "extra boards" are designed/developed/debugged (to make such board real-world usable) costs have multiplied.  Minimal MCU board suggested best left to Olimex/others - hate to see TI's unique/skilled tech resource "diluted" by hundreds of "board to board" interconnect and software issues. 

     

  • cb1,

    Everyone is different and I can acknowledge and respect it.

    I have a number of various LM3F boards and the ones well suited to my needs are for example:

    LM3S6965 Ethernet Eval Board

    LM3S9D92 Eval Board

    Evalbot and more...

    I still have the right to express my opinion (feedback) and ask questions (politely).

    Regards

  • @jan - of course you do - really no right/wrong - simply tried humor to support TI's marketing choice. 

    Believe that a "purpose designed/built" board - using new M4F - will best meet your need for size/performance.  (our firm is undertaking this same tack - we also are size constrained - yet benefit greatly by having "so many" features/functions all available on the Eval board)  Wish you well on your quest...

  • Jan,

     

    Wanted to let you know that we have heard your request and will consider it. We hear a request for a small and inexpensive kit often. 

     

    The board in the preview video with Miquel was a very limited quantity board mostly for internal use. It will not be available as a kit at this time.  It is actually physically larger than the EK-LM4F232H5QD

  • @Dexter - you are to be commended for always being interested/helpful - going the "extra mile."

    That said - our group was fortunate to receive the larger - 1st M4F board mentioned (populated w/157 pin BGA MCU).  Second M4F eval switched to 144 pin QFP - a substantially larger package.  As you are no doubt aware - the vast number of GPIO/alternate functions of such a beast resulted in a 45 pin, 0.1" pitch, array of pth along one side of the eval pcb.  (other side of the pcb almost as dense w/pth)  So - seems that "smaller/cheaper" Eval Bd likely best achieved with a down-sized package M4F.  (believe that 64 pin is "in the cards.")  Danger with the "excise" of key "added features" (i.e. color Oled & switch array, tri-axis accel, ADC conditioning/quick connect, neat USB accommodation) is that newer clients may "deluge" this special TI tech resource with "board to board" interconnect/signal management issues - often extending beyond the intent of a "Stellaris" forum.  (this has clearly resulted w/ similar "stripped-down" offering of "another.")  (he who does not study history...) 

    Hate to see TI's "great" investment/commitment to "unmatched, skilled/caring, hi-level tech support" - be diluted...  (think "unintended consequences"...)

    As small manufacturer, sometimes consultant - large/medium/small clients ALL "rave"  about the level, depth and sustained support TI "showers" on this forum.  (and other TI forums as well - but especially this Stellaris community)  TI's effort and continued commitment is greatly appreciated - kindly relay our/clients' appreciation and thanks...

    Dexter,

    Thanks for that. That's much appreciated.

    The form factor of LM3S6965 and LM3S9D92 is a great compromise IMHO.

    I can use it almost as it is, only connecting my stuff (sensors, transceivers, etc.)

    and it is easily mounted into standard rail enclosure - see pictures.

    Regards
