With the advent of IoT and industry 4.0 there has been a lot of hype
lately around bare metal and low level embedded software development.
Many make a distinction between C++ developers with and without
embedded experience, but what is really the difference when developing
in this domain and why is C still widely considered the pragmatic
choice. One of the crucial factors which is not well understood
outside of this domain are Interrupt Sercive Routines (ISRs). In order
to create a better understanding, this talk is a deep dive from no
previous experience all the way to an expert level understanding of
this feature. In this talk we will cover topics like jitter, latency,
priority inversion, starvation as well as the fundamental problems
ISRs cause in many mainstream C++ design patterns and even core
language features. I will also argue that ISRs change the basic
interface with regard to library abstractions and we will explore what
the alternate basic interface should look like.

Odin was allocated from a pool of hippies in the middle of the forest. He spent most of his career designing electronic circuits and programming micro controllers in assembler. One day after having shot himself in the foot particularly badly a friend introduced him to C++, a seriously powerful and ongoing addiction followed. Odin has authored many proof of concept libraries in the embedded field and is trying to revolutionize this domain. Odin co-authored the kvasir::mpl library, co-founded the embo.io conference and was a heavy contributor to the brigand library. In his day job, he teaches people how to shoot themselves in the foot less and get more from their compiler, both with his in-house team as well as in a training and consulting role.
