This two day, hands-on, workshop will give you a chance to explore numerous types of hardware interfacing, including:


For the hands-on portion of the workshop we will be using Raspberry Pi boards to implement a smart door bell


In the lectures, you will learn the theory necessary to implement such a device. Starting from power on, we will consider how Linux discovers what hardware is attached, and especially the role of the device tree. We will look how Linux represents hardware internally through the device driver model and the sysfs file system, and how it loads device drivers for each component of hardware. Then we will see how to interact with device drivers from user-space programs to make a working system.


We will be using the industry standard Yocto Project to build the disk images for the target. If you are not familiar with Yocto, don’t worry: we will be covering the fundamentals of Yocto as well.


The workshop is suitable for anyone working with Embedded Linux, or IoT devices, or is just curious about how things work


To get the best out of it you will need good command-line Linux skills (grep, find, bash), good C/C++ coding skills, and a basic knowledge of computer architecture (memory address spaces, interrupts, DMA)

Many of the things around you have Linux embedded inside: WiFi routers, smart thermostats, smart door bells. When writing code for these devices you have to be aware of the techniques available to access the hardware at a low level.

Cisco helps seize the opportunities of tomorrow by proving that amazing things can happen when you connect the unconnected. And, as a part of the Cisco portfolio, Webex Rooms connects people to productivity rather than getting in the way of it by promoting the ability for them to work where they want, when they want, and how they want to get stuff done. The world works better face to face, and whether there is a need to work remote or in-person, Webex Rooms delivers the collaboration tools for that authentic interaction. We are proud to have one of the largest R&D sites in Norway with over 400 employees, developing and designing collaboration tools!
