Thank you, I think I'll use 10k as I have it handy.

Thank you. Do I have to use 3.3kOhm resistor, or some other value may suffice?

Greetings.I am having the same issue. As i understand it -- pull-up resistor is when you connect CAN Rx to 3.3V or 5V on your STM board through a resistor. I wonder why did you use exactly 3.3k resistor and not 5k Ohm or something. And I would like t...
