FreeRTOS+TCP is still in the lab
FreeRTOS+TCP is already used in commercial products and we encourage you to try it yourself. Be aware however that we are still refining its design, and the source code and documentation do not yet meet Real Time Engineers Ltd's strict quality standards.
Please use the forum for support, feedback and ideas, or contact us directly if you have a specific business interest.

Open source and thread safe TCP/IP stack for FreeRTOS

FreeRTOS+TCP is a scalable, open source and thread safe TCP/IP stack for FreeRTOS.

FreeRTOS+TCP provides a familiar and standards based Berkeley sockets interface, making it as simple to use and as quick to learn as possible. An alternative callback interface is also available for advanced users.

FreeRTOS+TCP's features and RAM footprint are fully scalable, making FreeRTOS+TCP equally applicable to smaller lower throughput microcontrollers as larger higher throughput microprocessors.

See the FreeRTOS+TCP section in the tree menu (on the left) for a FreeRTOS+TCP networking tutorial, porting guide, API documentation, and a link to the free TCP/IP source code download.
