Add ulTaskGetRunTimeCounter and ulTaskGetRunTimePercent (#611) Allow ulTaskGetIdleRunTimeCounter and ulTaskGetIdleRunTimePercent to be used whenever configGENERATE_RUN_TIME_STATS is enabled, as this is the only requirement for these functions to work.
This repository contains FreeRTOS kernel source/header files and kernel ports only. This repository is referenced as a submodule in FreeRTOS/FreeRTOS repository, which contains pre-configured demo application projects under
The easiest way to use FreeRTOS is to start with one of the pre-configured demo application projects. That way you will have the correct FreeRTOS source files included, and the correct include paths configured. Once a demo application is building and executing you can remove the demo application files, and start to add in your own application source files. See the FreeRTOS Kernel Quick Start Guide for detailed instructions and other useful links.
If you have any questions or need assistance troubleshooting your FreeRTOS project, we have an active community that can help on the FreeRTOS Community Support Forum.
If using CMake, it is recommended to use this repository using FetchContent. Add the following into your project‘s main or a subdirectory’s
FetchContent_Declare( freertos_kernel GIT_REPOSITORY https://github.com/FreeRTOS/FreeRTOS-Kernel.git GIT_TAG master #Note: Best practice to use specific git-hash or tagged version )
add_library(freertos_config INTERFACE) target_include_directories(freertos_config SYSTEM INTERFACE include ) target_compile_definitions(freertos_config INTERFACE projCOVERAGE_TEST=0 )
set( FREERTOS_HEAP "4" CACHE STRING "" FORCE) # Select the native compile PORT set( FREERTOS_PORT "GCC_POSIX" CACHE STRING "" FORCE) # Select the cross-compile PORT if (CMAKE_CROSSCOMPILING) set(FREERTOS_PORT "GCC_ARM_CA9" CACHE STRING "" FORCE) endif() FetchContent_MakeAvailable(freertos_kernel)

The root of this repository contains the three files that are common to every port - list.c, queue.c and tasks.c. The kernel is contained within these three files.
./portable directory contains the files that are specific to a particular microcontroller and/or compiler. See the readme file in the
./portable directory for more information.
./include directory contains the real time kernel header files.
FreeRTOS files are formatted using the “uncrustify” tool. The configuration file used by uncrustify can be found in the .github/uncrustify.cfg file.
File checked into the FreeRTOS-Kernel repository use unix-style LF line endings for the best compatbility with git.
For optmial compatibility with Microsoft Windows tools, it is best to enable the git autocrlf feature. You can eanble this setting for the current repository using the following command:
git config core.autocrlf true
Some commits in this repository perform large refactors which touch many lines and lead to unwanted behavior when using the
git blame command. You can configure git to ignore the list of large refactor commits in this repository with the followig command:
git config blame.ignoreRevsFile .git-blame-ignore-revs
lexicon.txt contains words that are not traditionally found in an English dictionary. It is used by the spellchecker to verify the various jargon, variable names, and other odd words used in the FreeRTOS code base. If your pull request fails to pass the spelling and you believe this is a mistake, then add the word to lexicon.txt. Note that only the FreeRTOS Kernel source files are checked for proper spelling, the portable section is ignored.
