FreeRTOS-Plus-TCPOpen source and thread safe TCP/IP stack for FreeRTOS
FreeRTOS-Plus-TCP is a scalable, open source and thread safe TCP/IP stack for FreeRTOS.
FreeRTOS-Plus-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-Plus-TCP's features and RAM footprint are
fully scalable, making FreeRTOS-Plus-TCP equally applicable to smaller lower
throughput microcontrollers as larger higher throughput
microprocessors.
