The major task of my project is to learn something, something new to me, about the CAN-bus.
I don't wish to reversengeneer anything, don't want to make any commercial device or similar.
I wish to setup a CAN "playground" for me on the bench and study it, programming it, playing with it during the winter time.
As I described before, I wish to build up the stuff from what I have in my pocket right now, but ok, I learned something new again.
My transreceiver is not a version which I should have. Maybe a better option will be a MCP2515 CAN Bus Module TJA1050 receiver.
I'm familiar to write programs for uC ( my optionis AVR ) in C language.
I played around with Arduino and have one Arduino UNO R3 boar laying around, but I don't like Arduino too much.
I'm not an Arduino hater.
Yes, I have a logic analyzer where I can easy hook up the CAN bus ad select CAN bus package analyzing option in the logic analyzer,
but it is, again, more fun to make something from what I can learn.

Anyway, what hardware would I need to setup my project for CAN similarly described on my pic?
Even if you say I should go to arduino, ok I will do it with it.
Many thanks for every words, I really appreciate it.
My best regards.
