FreeRTOS: Programming for Real Time Operating Systems ( freertos | 14 hours )

• Familiarity with embedded systems
• Basic experience with C programming

Audience

• Engineers
• Engineering students
• Anyone interested in learning FreeRTOS
• Anyone interested in embedded systems

FreeRTOS is a cross platform real-time operating system (RTOS) kernel for embedded devices such as microcontrollers and small microprocessors.

In this instructor-led, live training, participants will learn how to code using FreeRTOS as they step through the development of a simple RTOS project using a microcontroller.

By the end of this training, participants will be able to:

• Understand the basic concepts of real-time operating systems.
• Learn the environment of FreeRTOS.
• Learn how to code with FreeRTOS.
• Interface a FreeRTOS application to hardware peripherals.

Format of the course

• Part lecture, part discussion, exercises and heavy hands-on practice

Note

• Participants are expected to provide their own hardware for this course (any STM32 board).
