Balancing Speed and Priority Crafting Embedded Networks for Diverse Real-Time Communication Demands
Since first publication of this article, the Controller Area Network (CAN), often referred to as CANbus, has solidified its position as a vital network in the embedded systems sector. Learn what has changed.
Article From 2003: An article giving answers to questions like: In which market segments are CAN, the Controller Area Network and CANopen used today? How many CAN bus nodes are out there? In which market segments will CAN and CANopen be used?
Introduction to CANopen including Device Profiles, Object Dictionary, Electronic Data Sheets, Process Data Objects, Network Management and implementation. CANopen is a higher-layer CAN protocol running on the CANbus. First published in Circuit Cellar.
CANopen application example that shows how CANopen can be modified to best match the requirements of a specific application.
More and more sensors are required to have networking capabilities. CANopen and DeviceNet are a good choice for simple sensors such as encoders or valves.
A guideline on how to utilize CANopen compliant communication channels to implement boot loader and debugger cores into microcontrollers with on-chip flash memory.
Article from 2003: There are some 22 or so chip manufacturers producing microcontrollers with on-chip CAN bus interfaces. Many differ substantially from each other - what are the selection criteria we can go by?
It is time to give this an update as with the evolution of technology and the proliferation of microcontrollers, there's an ever-expanding range of options when it comes to selecting a CAN controller.
