EK-TM4C123GXL: The cheapest TM4 evaluation board

Part Number: EK-TM4C123GXL
Other Parts Discussed in Thread: SN65HVD257

Hi All,

I'm trying to design a project which needs an MCU, a CAN and couple of I/Os to control an H-Bridge. Does anybody have a suggestion on selecting the TM4 processors? 

It should be a cheap project. 

Btw, I'd like to use the the experimental kit to test my project.

Does "EK-TM4C123GXL" kit meet my requirements? 

Is there any newer version for this experimental kit?

Thanks,

--Kash

    The EK-TM4C123GXL should meet you "cheap" requirement, but you will need to add the CAN transceiver. I don't know of any commercially available booster packs with a CAN transceiver (maybe someone else will post about one), but it should not be too hard to make one out of proto-board. The DK-TM4C123G development board has the CAN transceiver and terminal connections, but it is more expensive.

    Bob,
    Thanks for your message. I have "SN65HVD257 CAN EVM" which has two CAN transceivers. Can I use EK-TM4C123GXL with SN65HVD257 CAN EVM?

    Don't you think C2000 series is better for my case?

    Does that not depend as to whether "your case" seeks, "cheap or higher performance?"

    Minus (any) specifications - no one here knows what level of performance you (may) require...   Often - when those factors are "unknown" - it proves adequate to, "Start w/the most basic (lowest cost) unit - and determine "if" that choice - meets your requirements."

    Yes, that will work, but you will have to discretely wire the connections between the two boards. (Booster packs are designed to plug on top of launchpads.)

    The application is very simple: I have a master controller which sends CAN commands over CAN bus to TI MCU to spin two single phase BLDC motors. The TI MCU is supposed to control the motors with H-Bridge and publishes the current and temperature over CAN bus.

    So I'm sure I don't need a high performance processor, I have been working with C2000 but I think for a simple project like this I can find a cheaper (for sure has lower performance) processor.

    Thank you - are you sure that those BLDC Motors are "single" phase?    As such - your description of "How, BLDC motor commutation is achieved" via a "single phase" - would be most helpful...   (and would greatly aid the identification of a "most suitable" MCU)

    As you are aware - BLDC Motors  over-whelmingly employ three (sometimes more) phases - to achieve robust & well controlled motor commutation.    The "withhold" of your "single phase" application during your initial post (perhaps rightfully) raises concern...

    Yes, I'm sure it's not three phase.

    Thank you,

    Thank you - as firm/I have (some/slight) background in BLDC Control & BLDC Motors (as I suspect vendor crew has - as well) might you provide the maker & model number of that BLDC Motor.   (better still - a "link" to the motor's spec)

    Such would (then) enable the, best possible, MCU selection advice!       (matching your performance & low cost goals)
