Learning Objectives

  • Static allocation.

Concepts

Each FreeRTOS task requires 2 blocks of memory -

  • Task Control Block (TCB) - FreeRTOS-Kernel uses it to store the control information of a task.
  • Stack - Each task maintains its own stack.

If a task is created using xTaskCreate API, then the memory needed for TCB and Stack is allocated from the FreeRTOS heap by calling pvPortMalloc. If a task is created using xTaskCreateStatic API, then the memory needed for TCB and Stack is provided by the application writer.

Steps

  1. Complete all the TODOs in the source/tutorials/tutorial_3/source/tutorial_3.c file.

  2. Execute the following commands from the root of the repository to build:

    rm -rf build
mkdir build
cd build
cmake -B . -S ../source/ -DTUTORIAL=3
make

  3. Execute the following command to run the binary:

    ./freertos_example
