Topic: CyaSSL FreeRTOS / OpenRTOS Support


Did you know that the CyaSSL embedded SSL library supports FreeRTOS and OpenRTOS?  FreeRTOS is a real-time operating system for embedded devices which is designed to be both small and simple.  With an incredibly large user base, FreeRTOS/OpenRTOS supports 27 architectures and is downloaded from over 77 thousand times every year!

Just like CyaSSL, FreeRTOS is open source, royalty free, and very portable.  To build CyaSSL for FreeRTOS, uncomment the #define for FREERTOS in ./cyassl/ctaocrypt/settings.h.
