After working with FreeRTOS for over 7 years now, I've decided to start adding features and implementations that I wish would have been there at the beginning.

• C++ Wrappers

  • A collection of C++ wrappers encapsulating FreeRTOS functionality, allowing you to write your RTOS application in C++ while still using FreeRTOS. This wrapper layer does all the integration work for you.
  • This library is for you if you are planning on using C++ and FreeRTOS in your project but don't want to spend the time integrating the two.
  • Everything was testing successfully using FreeRTOS versions 8.2.3 and 9.0.0.
  • There are numerous demo / unit test projects using these wrappers and various features they provide. (Last count we are at 42 Demo projects showing how you might use the C++ Wrapper library.
  • Licensing is a modified GPLv2, the same as FreeRTOS.
  • Project web page
  • Full cross-referenced documentation. Documents were auto-generated and cross-referenced using Doxygen.

• Updated Linux port

  • Licensing is GPLv2 (this is a derivative work).
  • An update of the Linux / POSIX port of FreeRTOS, for testing and debugging on a Linux PC.
  • This update was tested successfully with FreeRTOS 8.2.3 and 9.0.0
  • Two Ubuntu workstations were also used, running 16.04 and 14.04, both 64-bit multicore machines.
  • This revised Posix port I renamed to Linux port, since I ended up using a few Linux specific APIs in it.
  • Thanks to William Davy who wrote the original Posix FreeRTOS port. He did amazing work simulating a real-time system under Linux.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.3.2
• Bug fixes to 1.3.1 regarding the critical section wrapper. Code prior to this version in critical.hpp will not compile successfully. Also added a Demo project using straight C and the updated Linux simulator only. Also note I am working through some configuration issues with Coverity. It is reporting 9 new defects, but these are false positives that the tool is not handling. When I added CPP_FREERTOS_NO_EXCEPTIONS, I also added Demo projects to test this. Coverity is incorrectly flagging these projects as not catching exceptions, when in fact these configurations are never throwing exceptions.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.3.1
• Bug fixes to 1.3.0, related to defining vTaskDelete to 0, as well as needing to make the Timer class's dtor virtual. Many thanks to Ewout Boks from the HAN technical college, Arnhem, the Netherlands for finding these.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.3.0
• Added preprocessor variable "CPP_FREERTOS_NO_CPP_STRINGS". If you do not want to use C++ strings, simply define this in your makefile or project. Note that if you define this, you must also define "CPP_FREERTOS_NO_EXCEPTIONS". Some classes throw exceptions if they cannot be constructed, and the exceptions they throw depend of C++ strings.
• Added an implementation of condition variables. These are not enabled by default. To use, define "CPP_FREERTOS_CONDITION_VARIABLES". Also include the files condition_variable.hpp and ccondition_variable.cpp in your project.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.2.0
• Adding preprocessor flag to exclude exceptions for smaller footprint and C++ compilers that do not support them.
• Updated license to one similar to FreeRTOS version. What does that mean for you? It means you are free to use FreeRTOS C++ Wrappers in your commercial product without making your product open source.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.1.0
• Adding object oriented work queues.
• Coverity scan analysis performed, with bug fixes.
  • See: https://scan.coverity.com/projects/michaelbecker-freertos-addons

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.0.2
• Fixed a major bug in Thread creation.
  • See: https://www.linkedin.com/pulse/apples-kumquats-perils-multi-threaded-polymorphism-michael-becker

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.0.1
• Changed license from GPLv3 to GPLv2 (or later) to accomodate FreeRTOS's modified GPLv2 license.
• See https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility for more information.

• https://github.com/michaelbecker/freertos-addons/releases/tag/v1.0.0
• Initial release.

This is my todo list for this project. If there's something you'd like to see done sooner, feel free to make a request.

• events
• MPU restricted threads
• eTaskGetState
• uxTaskGetNumberOfTasks
• uxTaskGetStackHighWaterMark
• Thread Local Storage

• In Timers, add OnStop / OnStart / mutex sync with these methods?
• Fixed size Memory pools (In progress)
• Priority queues
• Tick Hooks - option to round robin hooks, one per tick
