Ethenet TCP/IP

Hello Kiran

Yes, you can use LwIP's direct network calls in your application

Thanks Amit for your useful comment.

But I am confused about how to receive packets, and how to send send destination address, source address and my own packets.

Moreover I want to know how to change port number and packet size.

My application is as follows:

1. I am working on automation system in which SCADA software sends data request to remote slave station through wireless communication. 

2. LM3S9B96 based unit is used at remote location.

3. I am using Elpro-450U UHF radio (Ethernet port) for wireless communication.

2. Here microcontroller receives request from remote location, and it checks station ID, and sends data.

Can you help me to do this.

Hello Kiran

Documentation is on lwip wiki page for using the raw API's. I would suggest referring to the same and also look at the example enet_lwip which has a file for using UDP to transfer data.

Hi Amit,

Now I am using TM4C1294NCPDT and want to perform TCP/TP data transmit and receive on ethernet port.

Is there any example code to do the same?
