RIOT-2021.07 - Release Notes
|
|
|
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
RIOT is a multi-threading operating system which enables soft real-time
|
|
|
|
|
|
|
|
capabilities and comes with support for a range of devices that are typically
|
|
|
|
|
|
|
|
found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as
|
|
|
|
|
|
|
|
light-weight 32-bit processors.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
RIOT is based on the following design principles: energy-efficiency, soft
|
|
|
|
|
|
|
|
real-time capabilities, small memory footprint, modularity, and uniform API
|
|
|
|
|
|
|
|
access, independent of the underlying hardware (with partial POSIX compliance).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
RIOT is developed by an international open-source community which is
|
|
|
|
|
|
|
|
independent of specific vendors (e.g. similarly to the Linux community) and is
|
|
|
|
|
|
|
|
licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect
|
|
|
|
|
|
|
|
business models around the free open-source software platform provided by RIOT.
