FreeRTOS Real-Time Programming ONLINE
Standard Level - 5 sessionsview dates and locations
PLEASE NOTE: This is a LIVE INSTRUCTOR-LED training event delivered ONLINE.
It covers the same scope and content as a scheduled face-to face class and delivers comparable learning outcomes. Daily sessions comprise 4-6 hours of class contact time.
Real-Time Operating Systems (RTOSes) are operating systems developed for embedded microprocessors or controllers. These systems have the ability to immediately respond in a predetermined and predictable way to external events, so they must meet strict deadline constraints and handle different aspects of the application successfully.
A key feature of an RTOS is ensuring that most urgent operations are taken care of by assigning higher priorities. Real-Time systems also focus on the communication and synchronization between different tasks to achieve the objective of the application.
This course is based on FreeRTOS, the de facto and freely available standard RTOS for microcontrollers. Attendees will gain the knowledge and skills needed to develop and maintain applications running in a Real-Time environment.
Workshops comprise approximately 50% of class time, and are based around carefully designed Labs to reinforce and challenge the extent of learning.
The course is provided in partnership with embedded experts AC6.
What you will learn
- Cortex-M4 architecture overview
- Discover the concepts of Real-Time multitasking
- Understand Real-Time constraints
- Understand the FreeRTOS architecture
- Discover the various FreeRTOS services and APIs
- Learn how to develop FreeRTOS applications
Who should attend?
This course is designed for anyone interested in, or tasked with, the development of a resource constrained Real-Time system. For example - software engineers, field engineers and (project) managers.
- Prior attendance of C Programming for Embedded Systems is recommended
- Familiarity with embedded C concepts and programming
- Basic knowledge of embedded processors
- No hardware is required. The course uses a QEMU emulated STM32F407-Discovery board (Cortex/M4) with System Workbench IDE running on a virtual machine in the cloud. Delegates get to keep a copy of the virtual machine.
- Soft PDF copies of the course materials are provided to each delegate.
This course is provided in partnership with embedded experts AC6.
