CAN Article

mikroElektronika published an article in June 2009 issue of Elektor magazine about CAN. Our website visitors and users are welcome to read this article. Article contains useful information about practical usage of CAN and microcontroller. This article allows reader an easy example and tutorial on CAN usage. This article is written in several languages: English, German, Spanish, French and Dutch.

This article is provided with the detailed schematic and code example written in Basic, Pascal and C compilers for AVR, PIC, dsPIC and 8051 microcontrollers. Also in this article there is a picture showing working device.

CAN Article with source code for AVR microcontrollers

  English

It is often necessary to have several microcontrollers performing different operations integrated in one system in order to make them function as a whole. Here we show how to connect three microcontrollers to a CAN and how to use filters in CAN nodes for the purpose of filtering messages.

  Deutsch

Manchmal ist es notwendig, dass man in einem System mehrere Mikrocontroller für unterschiedliche Aufgaben einsetzt und die Teile dennoch als ein Ganzes arbeiten müssen. In diesem Beitrag geht es darum zu zeigen, wie man drei Mikrocontroller an CAN anbindet und wie man Filter in CAN-Nodes benutzt, um Messages zu filtern.

  Español

A menudo es necesario disponer de varios microcontroladores realizando diferentes operaciones, integrados en un sistema, haciendo que todos funcionen como uno solo. En este caso vamos a mostrar cómo conectar tres microcontroladores a un bus CAN y cómo usar los filtros en los nodos CAN para conseguir hacer un filtrado de mensajes.

  Français

Il arrive souvent qu’il est nécessaire d’intégrer plusieurs microcontrôleurs avec des fonctions différentes dans un seul système. Ici nous vous montrons comment connecter trois microcontrôleurs à un bus CAN et comment se servir de filtres dans les noeuds CAN avec afi n de filtrer des messages.

  Nederlands

Vaak moeten binnen een systeem meerdere microcontrollers verschillende bewerkingen uitvoeren om ze als een geheel te laten functioneren. Het volgende voorbeeld laat zien hoe drie microcontrollers worden aangesloten op een CAN-netwerk en hoe met filters in CAN-knooppunten berichten kunnen worden gefilterd.

   Srpsko-Hrvatski

Neretko se javlja potreba da se više mikrokontrolera koji vrše različite operacije integrišu u jedan sistem kako bi funkcionisali kao celina. U ovom tekstu ćemo pokazati kako umrežiti tri mikrokontrolera u CAN mrežu. Takođe, objasnićemo kako se koriste filtri u CAN čvorovima u cilju selekcije poruka.
