Hi,

      My project is using  canfd  module, and we encounted some questions, please see the drive code attach.

 

1. canfd transmit time:

    We put the canfd transmit module in 1 second task, but through the PCAN-View, it apperans 2s. I checked the PIT Timer,     and it is right for 1s.  When we  put the can(not canfd) transmit module in 1 second task,  through the PCAN-View, it      apperans 1s.

 

2.canfd interrupt:

   Through the PCAN-View , it  transmitted  canfd-standard  id and canfd-extended id msgs, sometimes  they both could  enter  receive interrupt, but sometimes canfd-standard id msgs could not   enter  receive interrupt, and canfd-extended id msgs could enter  receive interrupt.(0xC9  is canfd-standard id,  not everytime enter receive interrupt; 0x18FF00F5 is canfd-extended id and everytime could enter receive interrupt)

 

The attachment inclues  can.c and main.c.
