Supported and unsupported code
The main FreeRTOS .zip file download
contains all the official and supported FreeRTOS ports and demo applications.
This Community Contributions section makes available additional code that has
been contributed back to the project by its users. Community contributed code
is no longer included in the main FreeRTOS download.
The 'Officially Supported' and 'Contributed' FreeRTOS Code
page provides a more detailed explanation of the differences between officially supported and contributed FreeRTOS ports.
Accessing and using community contributed code
A separate forum is provided for
each microcontroller vendor. The contributed files are included as
attachments to the forum topics (threads) and can be downloaded without first
having to create an account or logging in.
Please do not use these forums for technical support
requests - a separate forum
is provided for this purpose.
Contributed files vary in their content. Some contain all the files
required to execute a demo, while others contain files that must be added
to the directory structure contained in the official FreeRTOS .zip file download.
Also some contributions are based on historic versions of FreeRTOS while others
use more recent versions. In most cases the version of FreeRTOS used in a
community contributed project can be easily updated by obtaining the latest
files from the FreeRTOS/Source directory of the main FreeRTOS download.
I would encourage anybody downloading a contributed file to also download the
latest official FreeRTOS release.
Some .zip files contain copies of the lwIP TCP/IP stack which
is licensed separately from FreeRTOS.
The lwIP license can be viewed here.
Please note that Real Time Engineers Ltd. cannot be held responsible for the contents
of any user contributed files, neither can we support them. Please report
anything that is included in this section that you think should be removed.
Also please be aware that OpenRTOS commercial licenses cannot be provided for
