TM4C1294 with SNMP support, LCD interface and 2 UARTS

Sandeep Chawla

Other Parts Discussed in Thread: EK-TM4C1294XL, UNIFLASH, SEGGER

I will most likely be selecting the TM4C1294NCPDTI3 device. However, I had some clarifications regarding this and would appreciate if you could help in that -

1. The launcpad link shows three versions
a. TM4C1294-SENSORHUB-BNDL
b. EK-TM4C-BLE-BNDL
c. EK-TM4C1294XL
I tried to find out the differences for these but was not able to locate that.
Can you send me the differences / link where this is available?

2. Since I have not designed with TI controllers earlier it is obvious that I will have to take the following Development tools:
a. Code Composer Studio (CCS) Integrated Development Environment (IDE) for TM4x ARM MCUs
b. Uniflash Standalone Flash Tool for TI Microcontrollers (MCU), Sitara Processors & SimpleLink devices

i. As per the TI website the CCS V7 is free to use on Windows OS and I do have to purchase a license. Is this understanding correct?
ii. Similarly the Uniflash Standalone Flash Tool for TI Microcontrollers (MCU) is free to use. Is this correct?

3. Where can I get the LWIP library and example codes for SNMP for the TM4C1294NCPDTI3 device?

4. I am attaching a block diagram of the circuit under consideration with Exar chipsets for the co-directional interface
and using TIs MCU and AFE.
Can the TI application team help in the schematic for the AFE and MCU connectivity to the Exar chips.

Best regards

    Hello Nima,

    Reference my post and attachment sent on 27 June, I would appreciate if you could share the updates and also the schematic as mentioned in the last point of the post.

    Alternately, you can let me know by when the application team of TI will share the schematic based on my requirement.

    Best regards

    Sandeep,

    This is the launchpad I have used.

    The examples for it can be find in TI Resource explorer. This is available both through CCS and web browser.

    Nima,

    Thanks for sharing the details. I will check this out.

    Meanwhile, is there any update  to he schematic for the AFE and MCU connectivity to the Exar chips. I had attached the block diagram of the circuit under consideration with Exar chipsets for the co-directional interface
    and using TIs MCU and AFE.
    I request you to please have the TI application team help in the schematic for the AFE and MCU connectivity to the Exar chips.

    Best regards

    Sandeep,

    My team and I are specifically MSP430 experts. You now have chosen the correct part for your system. This is a TIVA part (not MSP430). You will need to post on their forum for further technical support. I can post the thread for you or you can post it with the title and description of your choice.

    Please let me know if I can be of any help.

    Hi Nima,

    I would appreciate if you could post the thread to the correct group so that I can follow it up from there.

    Not so obvious actually.

    That's a vendor limited compiler. I would suggest looking at Kield, IAR and Rowely

    Similarly check Segger's J-Link

    It is unusual and (never) guaranteed that one vendor will invest significant time/energy in the search - followed by tech review - of another's device.

    (Please visit the site to view this (assumed, Exar) file)

    What site?     Your directive was supplied in your initial post (arriving here) - no such "site" is referenced.

    Nearly two weeks have passed since your initial post - might the absence of response to your Exar request suggest the following?

    • Replace your (overly) broad request for schematic w/key questions - which resolve the major connection issues/concerns - you may have.
    • Contact Exar similarly - yet again I'd ask key questions - rather than seeking a "full schematic."
    • If you persist in, "Schematic & only a schematic will do" - at minimum - START that "schematic" process!      Present something - then ask vendor to, "mark-up."

    Firm/I have noted - that if you can effectively, "Make your case" - vendor firms are (far) more likely to, "Go that extra mile!"      Yet - little appears here to "sell" your request...    

    Your presentation of, "How & Why" the "teaming of T.I. & Exar (in this specific design) makes great sense" - raises the odds (i.e. much encourages) a favorable response!
