Developer Tools // Micrium OS // TCP/IP Networking

TCP/IP Networking

A solid implementation of the TCP/IP protocol suite is an absolute necessity for any product intended to deliver Wi-Fi or Ethernet connectivity. The inclusion of the Micrium OS network stack in Simplicity Studio puts TCP/IP at your fingertips and allows you to accelerate development of your connected products. The codebase of the Micrium stack has been shaped by years of customer feedback and checked for compliance using industry-standard tools.
