xenomai3_rpi_gpio

overview

notes:
contains all notes I made during my investigation of getting xenomai 3 working on pi1,pi2,pi3 which contains lots of topics : - xenomai2 versus xenomai3 and legacy notes - apis's compiling and posix wrapping - rtdm and gpio(linux vs xenomai) - interrupts - cpu and irq load balancing and scheduling (linux vs xenomai) I call this sections notes and not documentation, because it contains also a lots of information copied from other sources for which I always place an url as reference.

Disclaimer: I also written down notes myself as I think it works, but there can be mistakes!

circuits overview of drawing and simulator tools used to create the models in this folder general documentation about electronic circuits, eg. pullup/pulldown, and there safety several circuit drawings from which some can be emulated NOTE: using the combined model one can test all examples in this repository!

examples
several examples to illustrate gpio input/output and interrupts linux and xenomai examples ( for xenomai both userspace and kernel space examples)

install descriptions how to install xenomai3 on the pi1 or the pi2/3 and some usefull startup tips and scripts to make a convenient image for the pi
