USB configuration

Other Parts Discussed in Thread: SW-DK-TM4C129X, TM4C129XNCZAD

I'm using TM4C129xx and I have a question about the USB I/F.

How  I configure the USB an a USB device? - I can't see it at the DS.

    TI provides a USB library as part of TivaWare so you don't have to write this level of code from scratch.

    Check out examples/boards/dk-tm4c129x/usb_dev_*

    Which can be found here http://software-dl.ti.com/tiva-c/SW-DK-TM4C129X/2.0/index_FDS.html

    Also, note the paragraph at the beginning of the USB chapter:

    Important:
    The full USB chapter is under NDA. This chapter describes the module features at a
    high level. For a copy of the full NDA data sheet, follow the instructions in the
    Non-Disclosure Agreement for the Tiva C Series TM4C129XNCZAD Microcontroller
    Data Sheet (literature number SPMS421)

    I have a Tiva Connected Launchpad. I am working on a project involving FreeRTOS and USB on TM4C1294 and I am required to submit code to open source. Seeing the licensing terms for USB, how do I share the USB part of the code ?

    Hello Diptopal

    You can always ask the end user to take the code from TI portal.

    Hi Amit, 

          Was on a break for a while. I will not be using any part of the TI supplied USB stack or Tivaware. It is a port of an open source USB stack with my own device drivers. In that scenario can I upload the USB stack to open source? I will not be sharing the datasheet under NDA.

       

          I am also planning to conduct a training on the USB interface of TM4C129NCPDT. In that case I will have to explain the USB interface from the NDA datasheet to the trainees. How should I go about doing this? Should I ask the trainees to download their copies of the datasheet under NDA for the training? Please advise.

    Regards

    Diptopal

    Might (some) here think or say, "Would it not be especially "poetic" if vendor's Amit also, "Was on a break for awhile" - and took 6+ months to respond?"

    Hello Diptopal

    If you plan to use a non-TivaWare open source USB Stack, it is upto the supplier's Licensing agreement that you need to adher to. TI has no liability in such cases. BTW, which stack is this?
