CppCon 2018

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.
