Ethernet communication between EK-TM4C1294XL and PC

Other Parts Discussed in Thread: EK-TM4C1294XL

I established communication between EK-TM4C1294XL launch pad and using Ethernet and the application is very simple; send and receive array of 8-bit data, the launch pads send and receive functions work fine but for the PC i can not receive or send data to the launch pad i do not want any online server as the examples provided by TI, i need raw offline Ethernet communcation. my question is is there a software that i can use to make the PC send and receive data from the launch pad and how to store the data received by the PC.

Hi,

I use SocketTest. You can download from here. https://sockettest-test-my-socket.soft112.com/

Hi Charles,

I downloaded wireshark to see the Ethernet packets on my PC. but the data received by the PC is not correct.

I used the simple send and receive packets example that is found in the TivaWare™ Library and it worked fine between two EK-TM4C1294XL launch pads but when i try to use the example to send the same data to the PC instead of another launchpad it does not work well, i read about the lwip library and it could help me to set IP address to the launch pad but all the examples found in the TivaWare™ are related to web servers and i just want to send data to the PC offline.

if you can help me find any resource that use the lwip library to send data to PC offline and show me how to configure it to transmit packets to PC and read from it, i would appreciate your help.

regards,

Abdelaziz

Hi Abdelaziz,

The TivaWare Ethernet examples as you know are making the MCU as a HTTP webserver. The MCU is connected to your local network and the IP address of your launchpad is acquired via the DHCP. It maybe a bit more complicated than a simple echo server. Below are some pointers for you to create LwIP echo server.
