Summary¶
This application note demonstrates the use of XMOS TCP/IP stack on an XMOS multicore micro controller to communicate on an ethernet-based network.
The code associated with this application note provides an example of
using the XMOS TCP/IP lib_xtcp Library and the ethernet board support
component to provide a communication framework. It demonstrates how to
send and receive text messages on the XMOS device in the
network using the UDP stack using lib_xtcp. The library features
low memory footprint but provides a complete stack of various
protocols.
Ethernet connectivity is an essential part of the explosion of connected devices known collectively as the Internet of Things (IoT). XMOS technology is perfectly suited to these applications - offering future proof and reliable ethernet connectivity whilst offering the flexibility to interface to a huge variety of “Things”.
The code associated with this application note provides an example of using the TCP/IP and Ethernet Libraries to provide a UDP loopback using a Reduced Media Independent Interface (RMII) and MAC interface supporting 100 Mbps.
Note: This application note requires an application to be run on the host machine to test the communication with the XMOS device.
