Communication with Tiva from a terminal via TCP/IP

Ahmed Wefky

Dear all,

My objective is to communicate and Exchange messages via TCP/IP with the Tiva connected Launchpad. This is to control its peripherals from a VB.NET application not from a web page. Actually I am new to this area. This is the first time I communicate with a ucontroller via Ethernet. The enet_io example in the tivaware library is interesting and informative. It deals with webpages not PC-based application.

I downloaded the enet_io example Project code to the Tiva Microcontroller. As shown in the attached image, I can connect as a TCP client and the board as a server.

The question now is what message (text strings) should I send via my terminal to switch on/off the LED or to change its update rate?

Best regards,

    Hello Ahmed,

    The enet_io example is geared to work with a CGI web page hosted by the micro and not direct message parsing. What you need to use is enet_lwip example which hosts a Server and then integrate your custom TCP port message parsing by opening TCP sockets. More details on the use of socket on lwIP site.
