VELOOS is an object-oriented message-triggered cooperative operating system for 8-bit Microchip microcontrollers licensed to public under the Open Software License
Release 1.0 includes VELOOS kernel and two timer drivers (TMR0 and TMR2 based). It has been tested on the following devices: PIC12F675, PIC16F690, PIC18F248.

This post continues series of examples and describes how VELOOS can be used for implementing time-triggered applications.

The previous post gave a brief introduction to VELOOS design idea. VELOOS assumes that an application is decomposed on PDOs (Process Data Objects). This post describes by example features provided by VELOOS for implementing PDO.

VELOOS - Very Low Overhead Operating System

VELOOS is a message-triggered cooperative operating system designed to run in places were a large vehicles can not run. Its implementation for PIC12F takes less than 200 instructions and 20 data registers¹. With addition of a timer driver, it becomes a time-triggered RTOS.

In this post I present my vision of e# reflected through history of assemblers. For each stage in the assemblers’ history I am providing presumptive equivalents in e#, incrementing the complexity of each next example.
(Continued)

I envision the following benefits of using e#

1. It will allow writing better quality code in shorter time
2. It will reduce maintenance cost by providing abilities for regression testing (on a simulator or in-circuit debugger)
3. It will reduce impact of migrating to another device/platform

(Continued)

1. Refine vision
2. Establish requirements
3. Design a device metamodel

Preface

I would like to discuss with you my ideas on new programming language for embedded applications, denoted further as e#. I value your time and therefore in this post I am trying to be short and precise as much as possible.
