Overview

Ethernet is a widely-used high performance networking technique for local area networks (LAN). Because of it's easy and inexpensive implementation, it is a very popular and reliable technology.

When invented it had a transmission rate of 2.94Mb/s and could support 256 devices over cable for 1km using CSMA/CD. To match with the high speed network requirements, it was continuously updated so now it supports a maximum data rate up to 10Gbps.

This article demonstrates how data can be sent and received over Ethernet in VC#.

Steps

  • Demo application can be downloaded from here.
  • Navigate to Solution Explorer in visual studio > Right Click on Solution > Properties > Devices.
  • Uncheck "Deploy the Latest version of the .NET Compact Framework (including Service Packs)".
  • Build and deploy the project on your WinCE device.
  • Download and Install .NET Compact Framework directly to the FlashDisk of the device from here.
  • Go to My Device > Program Files > vcsharp_ethernet_client_server_demo and run the application vcsharp_ethernet_client_server_demo.exe.

Configure TCP Client

  • Download any TCP Server application such as Hercules for your development PC .
  • Set the port number and run TCP server.
  • On your WinCE device, run vcsharp_ethernet_client_server_demo application.
  • In TCP Client tab, enter IP address of your development PC and port number for which server is configured and press Connect button.
