Overview

This sample implements an application using zbus to illustrate three different reaction options. First, the observer can react "instantaneously" by using a listener callback. It can schedule a job, pushing that to the system work queue. Last, it can wait and execute that in a subscriber thread.

Building and Running

This project outputs to the console. It can be built and executed on QEMU as follows:
