    "I don't know your layout but FIFO occupies by default the first 8 mailboxes" OK, that make a lot of sense now..... Did not understand that FIFO utilizes mailboxes....I thought they were seperate but equal so for me...

    Yes both MB and FIFO interrupts are enabled. Why would enabling FIFO stop MB from firing? As soon as enable the FIFO the MB stops responding? I also tried setting priority to MB but that seemed to do nothing. ...

    Also, do you always need "events"? I only added events with FIFO but when only using MB I never had "events" and only had interrupts. Does it matter in the order for calling "distribute"? Do you do this after you...

    Yes, I am using distribution() but that does not seem to stop both from firing. PS I do not care of both fire as I am using the FIFO for J1939 network messages only and I am using MB for the full filtering of the DBC...

    OK, I have a new one. So up to now I have been using MB filtering exclusively but for J1939 Network PGNs you need to mask them for that essentially only the PDU format and data page bits are used. This is because...

    You can set what ever you want in the call back function. I use the same call back function for CAN1 to 3 so I have a bit encoded uint8_t that I set and clear the bits based on the state of the frame received from...

    This is what the board lay out in case anyone is interested. I set up a circular buffer which seems to handle this better. Probably will move the 12v line in a new version. Presently there is nothing on the 12V...

    Well, swapped the the boards and the original combintation will not communicate. Swap them back and it works fine. Seems to be a mechanical interfacing issue between the processor edge connector and the ATP board...

    Did it, nothing. I have used the Teensy 3's and 4's and never have seen this. LED blinks but nothing happens when the boot button is pushed after the programmer pops up. Never seen this before.
