STM32H70-DK FDCAN Hello everyone: I want to use FDCAN in my board but it is not working. I've been using a few examples I've found as reference but none of them are for my exact board (STM32 H735). Does anyone have an example I can run?

Hi,

Is HSE essential for FDCAN ?
I'm looking at STM32H503EBY6TR for a simple CAN project, however, it does not have HSE capability, so would need to use HSI anyway.
What kind of data rates or temperatures do you start to get problems with FDCAN on HSI ?

Thanks
