Technical articles about embedded networking with CAN and CANopen, Embedded Internetworking and Microcontrollers

These articles offer tips & tricks about programming embedded microcontrollers with a focus on Controller Area Network, CANbus, CAN bus

Embedded Networking with CAN and CANopen

• CANopen API - Recommended Practice
  This is an attempt to provide a common application programming interface for CANopen solutions. The following CANopen implementations will be the first to adopt this new standard:
  • www.CANopenIA.com
  • www.MicroCANopen.com
  • www.CANgine.com
  A common setup and configuration tool for all of these is under development.
• Selecting a CAN controller
  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? 
• Betting on CAN and CANopen
  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 in the future?
• Embedded Networking with CANopen
  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.
• Customizing CANopen for Use in an Automated Laboratory Instrument
  CANopen application example that shows how CANopen can be modified to best match the requirements of a specific application. First published at the 8th iCC in Las Vegas.
• Smarten-up your Sensors with DeviceNet and CANopen
  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.
• CANopen compliant boot loader and debugger cores for Flash microcontroller
  A guideline on how to utilize CANopen compliant communication channels to implement boot loader and debugger cores into microcontrollers with on-chip flash memory.

Embedded Internetworking

• External (Electronic Design):
  It's Time To Implement Embedded Networking And Internetworking
  Implementation example for the CMX-MicroNet TCP/IP stack: a CANopen / Internet gateway implemented on the Philips 8xC591.
• Internet Connectivity: The time is right and the technology is ready for you
  Looks at various aspects of implementing Internet functionality in 8-bit microcontrollers, including a case study on a CAN to TCP/IP gateway. First published in EE Times.

8051 Programming

• Using Flash Memory in Embedded Applications
  Store and read variable and configuration data from within an application
• 8051 Coding and Debugging
  Giving you yet another reason to use C and NOT Assembly
• 8051 Memory Models
  Selecting the right memory model using the Keil and Raisonance C compilers
• Using C Pointers, Arrays, Structures and Unions with 8051 compilers
  Still unsure how pointers, arrays, structures and unions are used? Or how they can be set/located to specific addresses? This article is for you!
• Software-Based Memory Testing
  With code examples for 8051 and Philips XA
