Programming Industrial Embedded Systems

Course Description

This course gives practical knowledge about principles of development of complex industrial real-time embedded systems. Complex embedded systems: hardware and software architecture. State-of-the-art technology overview. Real-time operating systems (RTOS): multitasking, task scheduling, synchronization mechanisms, memory management. Software development environment for embedded systems. Complex embedded software development without RTOS in systems with minimum hardware requirements: file system and networking support example. FreeRTOS: architecture, task scheduling, interrupts, resource and memory management. Embedded Linux: hardware requirements, OS architecture, kernel, device drivers. Builing kernel and target hardware porting. Device drivers and user application development. uCLinux: particularities, hardware requirements, target hardware porting. eCos: architecture, hardware requirements, porting, device drivers and user application development. Practical examples.

General Competencies

Knowledge on particular aspects of hardware and software architecture of complex industrial real time embedded systems. Knowledge on structure of real-time operating systems, procedures of porting OS to target hardware, device driver programming and development of user applications. Fundamentals of porting and using some of the well known operating systems for embedded systems (FreeRTOS, Embedded Linux, uCLinux and eCos).

Learning Outcomes

  1. recognize specific aspects of hardware and software architecture of complex industrial real time embedded systems.
  2. use software development tools for complex embedded systems.
  3. modify chosen OS in order to adapt it to the target hardware (FreeRTOS, Embedded Linux, uCLinux and eCos).
  4. develop device drivers for real-time operating systems.
  5. develop user applications for real-time operating systems.
  6. estimate and choose optimal hardware resources for chosen real-time operating system.

Forms of Teaching

Lectures

Lectures are focused on theoretical and practical aspects of key course topics (two hours per week).

Exams

Continuous evaluation encompasses two written exams (midterm and final exam). Students who do not satisfy at continuous evaluation must undertake both the written and oral exam. Students are questioned at the laboratory exercises and they also obtain the points for a practical project.

Laboratory Work

Students are obliged to take laboratory exercises (15 hours). During the laboratory exercises, students learn about principles of complex embedded software development on practical examples by developing firmware for microcontroller development kits.

Consultations

Consultations for students are held once per week.

Seminars

Students develop practical project solutions (in groups of up to three students), following the ideas they propose themselves. They use the insights and knowledge acquired at the lectures and laboratory exercises. They demonstrate the knowledge about principles and guidelines for development of the complex embedded software through the implementation of practical project solutions.
