LatticeMico32 Tri-Speed Ethernet MAC Demo

Overview

This LatticeMico32 Tri-Speed Ethernet Media Access Controller (TSMAC) demo shows the capability of the TSMAC IP core to function in a real network environment.  The demo, designed to be simple and easy to use, requires no test equipment, lengthy setup or complex explanation. An application familiar to everyone, and practically synonymous with Ethernet and networking, is surfing the web. Because searching the Web is a familiar procedure to everyone, this demonstration uses a Web server to demonstrate the Tri-Speed MAC IP core, using the open-source lightweight IP (lwIP) network stack.

The demonstration runs on a LatticeMico32 Development Board for LatticeECP2 connected to another host computer (demonstration PC) on the same network or through a cross-over cable. The demonstration PC connects to the LatticeMico32 Development Board for LatticeECP2 over a standard 100 Base-T network, using a Web browser.
