Tasks

Introduction

If you need to perform any kind of background processing task, then you will need to consider how to break it up so it executes in small slices to allow other system functions to continue normally.

You can use callback timers to schedule periodic tasks, but if you simply need to run the task as soon as possible you should use the Task Queue.

Task Schedulers

At present Sming doesn’t provide any structured (class-based) support for task scheduling, however there are various scheduling libraries available for Arduino.

These are quite simple and generic:

• A very simple Arduino task manager
• TaskScheduler

This one is rather more complex:

• Task Scheduler

Using a scheduler is a powerful technique which allows the programmer to focus on the task at hand, rather than how to get it to run.
