OS3FreeRTOS Programming
Programming applications using the FreeRTOS operating system

Objectives

  • Understanding the FreeRTOS architecture.
  • Discovering the various FreeRTOS services and APIs.
  • Learning how to develop FreeRTOS applications.
  • Learning how to debug FreeRTOS applications.
  • Becoming familiar with FreeRTOS APIs.
  • Managing the Task priorities and clarifying the scheduling algorithm.
  • Explaining the inter-task communication.
  • Developping interrupt service routines.

Practical labs are conducted on STM32 boards under System Workbench for STM32.
(Keil or IAR can also be used for on site courses).
ACSYS is able to adapt the course to the Cortex-M based microcontroller chosen by the customer.
See our website for the various families we are covering: ST STM32, NXP LPC and Kinetis, TI Stellaris.
  • Example code, labs and solutions are provided to the attendees.
  • An ARM-based target board (Cortex/M) with a JTAG probe.
  • For open courses labs are done on STM32 boards using Sytem Workbench for STM32.
  • For on site courses, the customer may select Keil or IAR IDEs.
  • Familiarity with embedded C concepts and programming
  • Basic knowledge of embedded processors
  • Any embedded systems engineer or technician with the above prerequisites.
  • Prerequisites are checked before the training.
  • Progress is assessed by quizzes at the end of sections.
  • Each trainee receives a completion certificate.
  • If a prerequisite gap appears, alternative or additional training is offered.
