TM4C1294KCPDT: USB to Ethernet bridge software

Part Number: TM4C1294KCPDT

HI

Is there a code to implement a USB-to-Ethernet bridge based on  TM4C1294KCPDT or whatever?

I have found out that the USB CDC class implemented in TIVA software pack has no ethernet  type

// usbcdc.h - Definitions used by Communication Device Class devices.

// Note: This header contains definitions related to the USB Communication
// Device Class specification. The header is complete for ACM model
// devices but request and notification definitions specific to other
// modem types, ISDN, ATM and Ethernet are currently incomplete or
// omitted.

What options do I have?

    Hello Aleksey,

    We do not have support for USB to Ethernet in TivaWare. I would recommend going through the examples for USB and Ethernet and learn how they work, and then work to integrate the two functions.

    While the suggested 'approach' may work - it provides 'NO' Bridge Implementation - which proves (vital) to your requirement.

    Would not your search for (any) existing 'Bridge Examples' - along w/study of your two 'To be Bridged'  candidates  - provide (even) further insight & guidance?

    It is expected that:

    • Dissimilar Data Rates 
    • Loss of signal  (transient or extended) - between the 'Bridge' and either 'Side' or (even) 'Failure of the Bridge itself'
    • Error recognition - and (even) 'error correction'
    • and handshake 'mechanisms' - enabling far more precise & 'intelligent passage' of data

    will each be required - to meet the challenge - such 'Bridge' imposes.     

    None of those (critical points) are likely to 'reveal' - w/in your study of (either) communication mode.     Yet 'all' prove important - do they not?

    There are (many external) Tech sources - which may 'inform & advise' your "Bridge Creation.'     If you're willing to invest (some) time/effort in identifying (a few) such sources - my group is (sure) to be able to add (still more.)     Thus building a 'wider & deeper pathway' - to your 'Bridge Success!'

    Casting a (FAR WIDER) 'Bridge Search Net' - seems (obvious) ... does it not?      'One and only one' (SO limited) search - proves  FAR from optimal.     (and admittedly - avoided ALL 'Bridge Specifics!)

    'Gold Nuggets - do not often - fall immediately at/around one's feet!'
