Hello,

my question is what is the maximum delay time between SPI and CAN H/L in normal mode?

many thanks in advance!

    Melih,

    Thanks for reaching out, I just emailed our SPI throughput calculator to you. If you have any other questions come up you can come back to this thread and post, or send me an email. I'll be closing this thread for now though.

    Regards,

    Hi Melih,

    If you're asking for the time between the last SPI bit and the first CAN bit, my experimental data shows this delay will be around 2.5uS. This may vary with your SPI and CAN data rates. For throughput capabilities, please see the calculator shared by Eric Hackett.
