Embedded Systems Development with RTX RTOS

Course id: 0067

Synopsis

Developing embedded applications is traditionally fraught with reliability, responsiveness and lockup issues particularly due to the need to be coded in specific ways to mimic concurrency and multitasking. To refocus embedded development on the functionality of the system, a lightweight, real-time operating system (RTOS) should be used instead.

This course introduces the fundamentals of RTOS and concentrates on the paradigm needed to effectively solve real-world problems with RTOS. The course focuses on the RTX RTOS from Keil.

Course highlights
Participants would be using the popular RTX real-time operating system from Keil for this course.

What you will learn

This course concentrates on the theoretical and practical knowledge to allow participants to achieve the following learning outcomes. Upon completing the course, participants would be able to:
  • Understand the concept of real-time, task, multitasking, scheduling and context switching
  • Design programs based on a collection of tasks executing pseudo-concurrently
  • Use queues, semaphores and mutaxes for inter-task communication
  • Implement proper resource sharing methods to prevent task deadlocks and priority inversions
  • Respond and handle interrupts in a timely manner

Who should attend

This course is suitable for firmware engineers who are about to embark on RTOS-based projects.

Prerequisite

Participants are required to have a working knowledge of C. Experience in embedded C would be beneficial, though not essential.

Course methodology

This course is presented in a workshop style with example-led lectures interlaced with hands-on practical for maximum understanding.

Course duration

3 days.
