Changes between FreeRTOS V10.4.0 and FreeRTOS V10.4.1 released September 17 2020
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+ Fixed an incorrectly named parameter that prevented the
ulTaskNotifyTakeIndexed macro compiling, and the name space clash in the
test code that prevented this error causing test failures.
Changes between FreeRTOS V10.3.1 and FreeRTOS V10.4.0 released September 10 2020
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
Major enhancements:
+ Task notifications: Prior to FreeRTOS V10.4.0 each created task had a
single direct to task notification. From FreeRTOS V10.4.0 each task has
an array of notifications. The direct to task notification API has been
extended with API functions postfixed with "Indexed" to enable the API to
operate on a task notification at any array index. See
https://www.freertos.org/RTOS-task-notifications.html for more information.
+ Kernel ports that support memory protection units (MPUs): The ARMv7-M and
ARMv8-M MPU ports now support a privilege access only heap. The ARMv7-M
MPU ports now support devices that have 16 MPU regions, have the ability
to override default memory attributes for privileged code and data
regions, and have the ability to place the FreeRTOS kernel code outside of
the Flash memory. The ARMv8-M MPU ports now support tickless idle mode.
See https://www.freertos.org/FreeRTOS-MPU-memory-protection-unit.html
for more information.
Additional noteworthy updates:
+ Code formatting is now automated to facilitate the increase in
collaborative development in Git. The auto-formated code is not identical
to the original formatting conventions. Most notably spaces are now used
in place of tabs.
+ The prototypes for callback functions (those that start with "Application",
such as vApplicationStackOverflowHook()) are now in the FreeRTOS header
files, removing the need for application writers to add prototypes into
the C files in which they define the functions.
+ New Renesas RXv3 port layer.
+ Updates to the Synopsys ARC code, including support for EM and HS cores,
and updated BSP.
+ Added new POSIX port layer that allows FreeRTOS to run on Linux hosts in
the same way the Windows port layer enables FreeRTOS to run on Windows
hosts.
+ Many other minor optimisations and enhancements. For full details

contained are now available as a separate download.

notificatinos per task.

## Getting started
This repository contains FreeRTOS kernel source/header files and kernel ports only. This repository is referenced as a submodule in [FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS) repository, which contains pre-configured demo application projects under ```FreeRTOS/Demo``` directory.
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](https://www.freertos.org/FreeRTOS-quick-start-guide.html) for detailed instructions and other useful links.

@ -33,3 +33,7 @@ See the readme file in the ```./portable``` directory for more information.
### Code Formatting
FreeRTOS files are formatted using the "uncrustify" tool. The configuration file used by uncrustify can be found in the [FreeRTOS/FreeRTOS repository](https://github.com/FreeRTOS/FreeRTOS/blob/master/tools/uncrustify.cfg).
### Spelling
*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.
