FreeRTOS Library Categories
Introduction
Each library documented on this website falls into one of the categories described below. All the libraries are MIT (open source) licensed and are designed for resource constrained devices such as microcontrollers and small microprocessors. FreeRTOS core and FreeRTOS for AWS libraries do not have any dependencies other than on the standard C library – they are not even dependent on an RTOS.
Category Descriptions
The FreeRTOS kernel
The FreeRTOS kernel itself. This library includes the RTOS kernel, intertask communication primitives and intertask synchronisation primitives.
Libraries that implement open standards based connectivity, security, and related functionality. These libraries are suitable for building smart microcontroller-based devices that connect to the cloud. Unlike the FreeRTOS-Plus libraries (see above), FreeRTOS Core libraries have no dependencies other than on the standard C libraries, so FreeRTOS Core libraries are not dependent on the FreeRTOS RTOS kernel.
Libraries that implement clients for AWS IoT specific value add cloud services, including over the air updates (OTA). These libraries are suitable for building smart microcontroller-based devices that connect to the AWS IoT cloud. Like the FreeRTOS core libraries, they have no dependencies on anything other than the standard C library, so are not dependent on the FreeRTOS RTOS kernel.
FreeRTOS Labs libraries are functional but either incomplete, experimental, or simply provided for open source community interest. See the individual library documentation pages for a description of which criteria applies to that library.
