NUCLEO-F412ZG CAN Configuration issue

JDOG · ‎2024-04-05

I having trouble getting the correct CAN timing configured with default 96Mhz System Clock on the NUCLEO-F412ZG eval board.

I need a 250kbit/s baud rate.

Here is what I have so far.

The system clock setup is below.

The ABP1 clock rate is 48MHz, not 96MHz.

Try these values to get 250kbit/s

If you FIFO doesn't work, then it's called GIGO.

Hello,

Not sure I've understand the issue.

You need a bitrate of 250kb/s but I see you got it according to the screenshot. Could you please elaborate?
