IT-EOS1

Version

3.0

Offered by

ICT Engineering

ECTS

Prerequisites

Students must have a basic understanding of computer architecture, programming and electronics, comparable to the courses CAO I1 and ESW I1.
Practical experience with computer networking is an advantage.

Main purpose

Students will acquire basic knowledge about the Linux Operating System and practical experience in development of an IoT-device based on a combination of self-made and Open Source software.

Knowledge

Having completed this course, students should be able to:

- Account for advantages and disadvantages of Linux as operating system in embedded systems.
- Describe the anatomy of a 32-bit embedded system.
Describe the features of a BeagleBone system.
- Describe the boot process of a 32-bit ARM based Linux system.
- Explain Pulse Width Modulation.
- Explain I2C communication bus technology.
- Explain the structure of Linux file system and access permissions.
- Explain how to connect and read input from sensors in an embedded Linux environment.
- Explain how to connect and control actuators in an embedded Linux environment.

Skills

Having completed this course, students should be able to

- Use basic Linux commands and utilities.
- Select, install, configure and use tools needed for developing embedded systems.
- Execute a firmware upgrade on a BeagleBone system.
-Install and configure “off the shelf” software in Linux.
- Use the GPIO structure in Linux to interface sensors and actuators.
- Use Pulse Width Modulation for Control of servo motors, and LED light intensity.
- Implement BASH scripts to control simple GPIO devices.
- Implement simple hardware circuits for measurement and control.
- Use appropriate programming language to implement web based user interface.

Competences

Having completed this course, students should be able to:

- Implement shell scripts in BASH
- Design and implement IoT-devices, based on a 32-bit MCU platform with Linux
