Learning Objectives

• Scheduling Algorithms.

Concepts

FreeRTOS-Kernel supports the following 3 scheduling algorithms:

1. Prioritized Preemptive Scheduling with Time Slicing
2. Prioritized Preemptive Scheduling without Time Slicing
3. Co-operative Scheduling

Co-operative Scheduling

The required FreeRTOSConfig.h settings are:

#define configUSE_PREEMPTION    0

When the co-operative scheduling is used, a context switch will only occur when the Running task enters the Blocked state, or the Running task explicitly yields (manually requests a re-schedule) by calling taskYIELD(). Tasks are never preempted, so time slicing cannot be used.

Steps

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

   rm -rf build
   mkdir build
   cd build
   cmake -B . -S ../source/ -DTUTORIAL=8
   make

2. Execute the following command to run the binary:

   ./freertos_example

3. Understand the output.
