J1939 emu nucleo F series

Hi, just wondered if can I implement a kind of simulator for this can bus, the idea is to provide can data like trucks to an embedded system, does anyone know a similar project to start with?

I don’t know if such a task is very poor thing for a nucleo board like this

Hello and welcome!
Regarding the hardware side, I would suggest you to go with a dedicated CAN bus module (there are lots of “arduino compatible” ones) as an interface between your MCU and the vehicle’s CAN bus.

For simulators check the answers on this stackoverflow question and see if it’s of any help to you. Haven’t tried those solutions, but seem pretty sound.
