Topic: Fastest way to detect ID

Hello,

What is the fastest way to detect a specific ID?
I've tried with "equal to" between CAN0 RX IDL and for instance constant ID:0x123, but as soon as I put the result on digital output and measure with a logic analyzer, detection works great but seems to wait the entire frame before setting the output.
Is there a better (faster) way to achieve that (using gateway or so)?

Thank you

Best regards

Nicolas

No.

But what exactly problem you want to solve? Maybe it is possible to solve it in another way.

Hello,

I would like to identify ID as fast as possible to try to inject fault in the Bus.
Using a IO with an external CAN Driver, I would like to force a dominant level in the data frame or after a precise delay when detecting specific ID.

Thank you

Regards

Most likely, you cannot do this using CANNY.
But you can place CANNY 7.2 Duo "in-cut" of CAN bus near this ID source ECU and just exclude all messages with this ID from CAN bus traffic using CAN Gateway Driver: https://cannylogic.com/docs/c72duo/cang … ansmission
