µC/TCP-IP

μC/TCP-IP is an open source TCP/IP protocol stack, optimized for embedded systems. It features dual IPv4 and IPv6 support, an SSL/TLS socket option, and support for Ethernet, Wi-Fi, and PHY controllers.

μC/TCP-IP requires the presence of an RTOS for task scheduling and mutual exclusion. To meet this requirement, μC/TCP-IP readily accommodates μC/OS-II and μC/OS-III. Other non-Micrium kernels can also be adapted to μC/TCP-IP, but are not supported.
