Source Organization
[Getting Started]

Basic directory structure

The FreeRTOS download includes source code for every processor port, and every demo application. Placing all the ports in a single download greatly simplifies distribution, but the number of files may seem daunting. The directory structure is however very simple, and the FreeRTOS real time kernel is contained in just 3 files (4 if co-routines are used).

From the top, the download is split into two sub directories:

FreeRTOS
    ¦
    +-Demo      Contains the demo application.
    ¦
    +-Source    Contains the real time kernel source code.

The majority of the real time kernel code is contained in three files that are common to every processor architecture (four if co-routines are used). These files, tasks.c, queue.c and list.c, are in the source directory.

Each processor architecture requires a small amount of kernel code specific to that architecture. The processor specific code is contained in a directory called Portable, under the Source directory.

The download also contains a demo application for every processor architecture and compiler port. The majority of the demo application code is common to all ports and is contained in a directory called Common, under the Demo directory. The remaining sub directories under Demo contain build files for building the demo for that particular port.

FreeRTOS
    ¦
    +-Demo
    ¦   ¦
    ¦   +-Common    The demo application files that are used by all the ports.
    ¦   +-Dir x     The demo application build files for port x
    ¦   +-Dir y     The demo application build files for port y
    ¦
    +-Source
        ¦
        +-Portable  Processor specific code.

The following subsections provide more details of the Demo and Source directories.

RTOS source code directory list
[the Source directory]

To use FreeRTOS you need to include the real time kernel source files in your makefile. It is not necessary to modify them or understand their implementation.

The real time kernel source code consists of three files that are common to all microcontroller ports (four if co-routines are used), and a single file that is specific to the port you are using. The common files can be found in the FreeRTOS/Source directory. The port specific files can be found in subdirectories contained in the FreeRTOS/Source/Portable directory.

For example:

If using the MSP430 port with the GCC compiler:
The MSP430 specific file (port.c) can be found in the FreeRTOS/Source/Portable/GCC/MSP430F449 directory, and all the other sub directories in the FreeRTOS/Source/Portable directory relate to other microcontroller ports and can be ignored.
If using the PIC18 port with the MPLAB compiler:
The PIC18 specific file (port.c) can be found in the FreeRTOS/Source/Portable/MPLAB/PIC18 directory, and all the other sub directories in the FreeRTOS/Source/Portable directory relate to other microcontroller ports and can be ignored.
And so on for all the ports ...

FreeRTOS/Portable/MemMang contains the sample memory allocators as described in the memory management section.

Demo application source code directory list
[the Demo directory]

The Demo directory tree contains a demo application for each port. Most of the code for the demo application is common to every port. The code that is common to every port is located in the FreeRTOS/Demo/Common directory. See the demo application section for more details. Port specific code, including the demo application project files, can be found in sub directories contained in the FreeRTOS/Demo directory.

For example:

If building the MSP430 GCC demo application:
The MSP430 demo application makefile can be found in the FreeRTOS/Demo/MSP430 directory. All the other sub directories contained in the FreeRTOS/Demo directory (other than the Common directory) relate to demo application's targeted at other microcontrollers and can be ignored.
If building the PIC18 MPLAB demo application:
The PIC18 demo application project file can be found in the FreeRTOS/Demo/PIC18_MPLAB directory. All the other sub directories contained in the FreeRTOS/Demo directory (other than the Common directory) relate to demo application's targeted at other microcontrollers and can be ignored.
And so on for all the ports ...

Creating your own application

When writing your own application it is preferable to use the demo application makefile (or project file) as a starting point. You can leave all the files included from the Source directory included in the makefile, and replace the files included from the Demo directory with those for your own application. This will ensure both the RTOS source files included in the makefile and the compiler switches used in the makefile are both correct.
