I am new to this TM4C1294NCPDT, I looking for the support to enable TCP/IP socket programming using lwip.

I want to this for MODBUS communication over TCP/IP.

Along with MODBUS we required HTTP server also.

Can you please share relevant document and source code which can help us.

    Hello Raj,

    I have asked my colleague to help you with socket programming using lwIP.

    Hello Raj,

    Did you look at the following TI Design?
    www.ti.com/.../TIDA-00226
    www.ti.com/.../TIDM-TM4C129XS2E

    TIDA-00226, has software for Modbus implementation. The software, in this TI Design, is designed to work on a custom board (whose schematic and Gerbers are provided with the TI-Design, if you want to use it). Also it does not have a HTTP Server implementation.

    TIDM-TM4C129XS2E runs on EK-TM4C1294XL board using FreeRTOS and lwIP. It also has a HTTP server implementation. But this software does not include a Modbus protocol implementation. Instead it includes a Telnet implementation.

    I believe using the software from the above mentioned TI-Designs, you should be able to come up with a solution that you are looking for, on EK-TM4C1294XL board.

    Note: BSD socket style APIs are not supported with TM4C port of lwIP. You will have to use native lwIP APIs for Socket programming.

    Thanks,
    Sai
