Future use of CAN FD
  • 0
  • Developing a CAN design these days should consider an upgrade to CAN FD. CAN FD is in discussion since two years and I expect first cars using it in late 2015. Hopefully Microchip or Bosch will offer an SPI connected CAN controller supporting CAN FD. I'm not sure if SPI is a good solution handling the larger amount of data. Any thoughts on this topic?

  • IIRC, CAN-FD is going to be an optional component of ISO 11898-1 (since bandwith exhaustion is still only a limited issue). Given that, focus should remain on the current standard, with potentially community-driven development for optional support for -FD.

    Sorry for the delay guys I'm slammed trying to get the CBT units out.

    Definitely something to consider for future versions.

  • Automotive experts are working hard to establish CAN FD in cars. General Motors, Daimler, VW and more. We had a CAN FD Plugfest in October last year were all main micro controller manufacturers took part.
