In this tutorial we will see how to setup the Arduino IDE for FreeRTOS.<br>
After setting up the IDE, we will run the first FreeRTOS example on Arduino Uno.<br>

=Setting Up=
Download and install the Arduino IDE from [https://www.arduino.cc/en/Main/Software this link].<br> 
Downlaod the FreeRtos files form the [https://github.com/ExploreEmbedded/Arduino_FreeRTOS github] and paste into the library folder of arduino.<br>
The folder structure should be as shown below.

=Running First Example=
Now run the the IDE and open the first example from <b>File->Examples->FreeRTOS->01-TaskSwitching</b> as shown in below image.<br>

Compile and upload the code. Open the serial monitor to see the output.<br>

=FreeRtos Configuration=
Please check this [http://www.freertos.org/a00110.html tutorial] for freeRtos configuration.<br><br>

=Heap Settings=
The original free rtos project can be downloaded [https://github.com/feilipu/Arduino_FreeRTOS_Library here].<br>
It uses heap_3.c file and memory allocation is done by malloc() and free() functions. Heap size needs to be configured through linker setting and <b>configTOTAL_HEAP_SIZE</b> setting in FreeRTOSConfig.h has no effect.<br>
In order to solve this we will be using heap_4.c.
Please check [http://www.freertos.org/a00111.html this link] for more info on freeRtos heap usage.

=Downloads=
