Sample code for receiving query and sending data over Ethernet.

Anil Bhide

I am using TM4C1294 development board.

I am want a sample code for receiving query & sending data over Ethernet port.

This is something similar to MODBUS Protocol, where device receives a query from Master & answers with the required set of data (Few hundred bytes)

Please help

    Hello Anil,

    It seems to be similar to Serial 2 Ethernet TI Reference Design

    Such design is usually classified as, "Command & Response" and usually - but not always - sees "only the master" command/interrogate the slaves.   There's a weakness here - as the slaves gain intelligence (via MCU inclusion) it proves useful for the slaves to be able to, "Request Servicing" from the master.

    Your "steering" this requirement into the "Ethernet realm" opens a, "Pandora's box" of new issues, complications & uncertainties.   As mostly (i.e. always) proves true - your post elevates the complexity of  "solution" (by choosing Ethernet) while (completely) avoiding ANY/ALL justification for its need. (i.e. CAN or SPI - vastly simpler - cannot be employed?)
