Developed in partnership with the world's leading chip
companies over a 12 year period, FreeRTOS
is the market leading
real time operating system (or RTOS), and the de-facto standard solution for microcontrollers and small microprocessors.
Real Time Engineers Ltd have partnered with Nabto to
develop FreeRTOS+Nabto, a product that brings
simplicity, platform independence, and entry level access to Nabto's
peer to peer Internet of Things solution.
FreeRTOS+Nabto is a small piece of C code (23K inclusive
of FreeRTOS and the UDP only IP networking stack) that, when
integrated into an embedded networked device, allows
that device to be remotely accessed and controlled
using a rich web based user interface or intelligent
data acquisition system.

FreeRTOS+TraceTM
(part of the FreeRTOS+ ecosystem showcase) is a sophisticated trace tool for FreeRTOS.
With more than 20 graphically interconnected
views, FreeRTOS+Trace provides a world leading level of insight into the run-time behaviour of your FreeRTOS application. It has
become an indispensable debugging and optimisation tool.
Commercial Licensing & Middleware
OpenRTOS is a commercially licensed and supported version of FreeRTOS
that includes fully featured professional grade USB, file system and TCP/IP components.
OpenRTOS is provided by a global engineering company under license from Real Time Engineers Ltd.
SafeRTOS is delivered as
source code, with as much or little
certification evidence as
required. Certification packs and design history files are
available that specifically target applications that fall under
IEC 61508, EN62304 and FDA 510(k) regulatory requirements.
SafeRTOS has been specifically designed for the (primarily 32-bit) microcontroller market, resulting in a design that
is highly optimised for use in applications where a small code size footprint is essential. The SafeRTOS ROM footprint
is typically in the 7K to 14K bytes range.
FreeRTOS Masterclass Training
Investing in training allows your team to be as productive as
possible as early as possible, lowering your overall development
cost, and enabling you to bring a more robust product to market
earlier than would otherwise be possible.
The FreeRTOS Masterclass course
is presented by
Real Time Enigneers Ltd's CTO Richard Barry,
who is both the architect and key author of FreeRTOS,
and so also the world's leading
authority on what is the world's most popular real
time kernel for deeply embedded MCU designs.
Obtaining your training from Richard ensures your
team will gain directly from his in-depth and leading edge
product knowledge, and years of usage experience.
Masterclass training can be tailored to your needs.
Did you know?
FreeRTOS is downloaded every 260 seconds (on average).
Most people take products to market without ever contacting us,
but with the complete peace of mind that they could opt to switch to a fully
indemnified commercial license (with dedicated support) at any
time.
FreeRTOS is designed to be simple and easy to use: Only 3 source files that are common to all RTOS
ports, and one microcontroller specific source file are required, and its API is designed to be
simple and intuitive.
The RL78 port can create 13 tasks, 2 queues and 4 software timers in under 4K bytes of RAM!
"It's probably safe to say at this point that FreeRTOS goes through more 'peer-review' than any other RTOS available on the planet.
I have used it in several projects - one of which was a multiprocessor environment that used more than 64 processors and needed to run for months
reliably. The RTOS core performed well.
Take FreeRTOS for a spin." - John Westmoreland
FreeRTOS is a risk free choice, providing the best of all worlds:
FreeRTOS is truly free and supported, even when used in
commercial applications. The FreeRTOS open source license
does not pose any risk to your
proprietary software. You can take
a product to market using FreeRTOS
without even talking to us, let alone
paying any fees, and thousands of
people do just that. If, at any time,
you would like to receive additional
backup, or if your legal team require
additional written guarantees or
indemnification, then there is a simple
low cost commercial upgrade path.
Your peace of mind comes with the
knowledge that you can opt to take
the commercial route at any time you
choose.
Here are some reasons why FreeRTOS is a good choice for your next application - FreeRTOS...
Provides a single and independent solution for many different architectures and development tools.
Is known to be reliable. Confidence is assured by the activities undertaken by the SafeRTOS sister project.
Is feature rich and still undergoing continuous active development.
Has a minimal ROM, RAM and processing overhead. Typically an RTOS kernel binary image will be in the region of 6K to 12K bytes.
Is very simple - the core of the RTOS kernel is contained in only 3 C files.
The majority of the many files included in the .zip file download relate only to the numerous demonstration applications.
Is truly free for use in commercial applications (see license conditions for details).
Comes with a porting, platform development, or application development service should it be required.
Is well established with a large and ever growing user base.
Contains a pre-configured example for each port. No need to figure out how to setup a project - just download and compile!
Has an excellent, monitored, and active free support forum.
Has the assurance that commercial support is available should it be required.
Provides ample documentation.
Is very scalable, simple and easy to use.
FreeRTOS offers a smaller and easier real time processing alternative for applications where eCOS, embedded Linux (or Real Time Linux) and
even uCLinux won't fit, are not appropriate, or are not available.
