RL78/F14 CAN drivers.


I am using IAR RL78 embedded workbench. I am looking for CAN driver. Where I can find the RL78/f14 CAN driver. 


  • Hi Sush,

    What version of IAR are you using? I think, there's a CAN example for RL78F13 in IAR EW 7.0 which you can get information that you can use for the F14 if I'm not mistaken.

    Hi JB,

    Thanks for the reply. The version I am using is IAR EW 7.4.

    But if we look at downloading site of IAR there are only two version available for RL78 3.10 and 2.21.
    So how do I get that examples. Can I still download IAR EW 7.0.

  • In reply to Sush:

    7.0 and 7.4 are NOT version numbers of EW. These are version numbers of the IAR IDE.
    IDE version 7.0 is used in EWRL78 V.1.40.
    IDE version 7.4 is used in EWRL78 V.2.21.
    The RSCAN sample is only included in EWRL78 V.1.40. It is not included in V.2.21.
    The example of V.1.40 can be imported and compiled in V.2.21. I have no idea if it works.

    Hi Frank,

    Thanks for the reply Frank. How can I download V.1.40 because I think its not available for downloading. Only 3.10 and 2.21 is available.

  • Hi JB and Frank,

    Thanks for your helpful comments. I really appreciate your help in resolving the problem.
    My project has been stuck since long time because of CAN drivers. If it is possible can you please provide the link to download RSCAN or If you have sample code or examples or RSCAN driver, can you please share with us.
