The highlights in the new version of the embedded CANopen stack are:

  • More clarity and easier maintenance in user-configurable files by dividing call back functions into multiple files
  • More flexibility by adding many more data call backs for SDO accesses
  • Framework support to guard Object Dictionary entries with auto-generated minimum and maximum values from EDS/DCF file

Customers with ongoing maintenance agreement with us are entitled to a free upgrade. In this case, please download the new version from

CANopenStore.com/support.php

using the activation code(s). For those projects using auto-generated code, also update CANopen Architect EDS to the latest version.

The process to update embedded firmware libraries that become part of a bigger project can be complicated. For that reason, we have developed tools and to ease this on-time task.

Contact us if you are interested in obtaining or need assistance in performing the update.

His key note also included the call upon us engineers to do more to ensure that embedded systems use less power. With the billions of microcontrollers out there, all the milliwatts that we can potentially save in each one do add-up. Although many microcontroller manufacturers already offer multiple power saving options on their devices, it is not always easy to get exact values. Any change in clock rate, also on any of the peripherals, immediately has an affect on the overall power consumption. But how much do we really save by reducing the clock to a communication peripheral?

This year, one of the Embedded Awards given out every year at the Embedded World is for a product that helps engineers with measuring the power consumption of their system dynamically. The PowerScale by Hitex not only allows measuring a system’s current power consumption – it makes that information available via an API so that debuggers can include the information into the trace recording or other displays.

This allows engineers to easily determine which code areas have an impact on the overall power consumption. The power-saving effect of reducing clock rates or disabling unused peripherals becomes immediately visibile.

Various adapter probes including a USB and Power-over-Ethernet Probe are available to allow for an easy connection of the up to four channels to the target hardware.
