Resolved! How do I set correct stdID for CAN-BUS?

Hi! I've seen some tutorials on can communication and notice that each of them use different StdId's. I'm using two nucle-l433rc-p boards, do I need a specific StdId or will any number between  0 and 0x7FF suffice?

Resolved! STM32L4R5 using OCTOSPI2 @LQFP100

Is there any chance to use both OCTOSPI (as 2xQSPI) with a LQFP100 package? There is a OCTOSPIM_P2_NCS but no OCTOSPIM_P2_CLK and Multiplexed Mode is not possible (only on P/Q-variants). Thanks in advance!
