Ok, I looked into ESP pin callback implementation and found that these callbacks belong to root pointers. Am I on the right way? Root pointers are not why you’re failing here. Look at the implementation of mp_call_function_0() and you’ll see your problem: you’re not passing the type it expects. Sen...

Short version: you’re not sending a micropython object ie it’s more complicated.

Long version: forthcoming.

What puzzles me however is that there is real frame loss at high baud rates (>=500 kbps) when sending non-stop. For a frame to be placed on the CAN bus, it must be acknowledged by at least one other node (that sends an active ACK bit). Obviously the CAN controller of the receiving pyboard must have...

Did you put terminating resistors?

When you say precompiled do you mean
.c -> .obj (compile c-code to binary)
or
.py -> .mpy (compile python source to byte-code)

So I schedule a callback-function in the timer callback-function? What do I do with the arg-argument of the schedule-function if I'm scheduling a function with no args? Thanx!

There are rules about ISRs: https://docs.micropython.org/en/latest/reference/isr_rules.html Unless you have a time-sensitive action to take, you should consider using micropython.schedule https://docs.micropython.org/en/latest/library/micropython.html?highlight=schedule#micropython.schedule With thi...

The crash is in mp_obj_fun_get_name.

Try commenting out the lines therein and adding them back one at a time.

If you have a debugger, it’s easier cause you can just put a breakpoint in mp_obj_fun_get_name and see where it dies.

I think your script just exits cause there’s nothing to keep it from exiting.

Just to test, put an infinite

while True: pass

loop at the very bottom.
