Hello, I have a similar problem. I am trying to send CAN messages from Raspberry pi through a CAN module mcp2515 through the SPI interface to the bus, but no CAN message is sent. I then used the oscilloscope to observe the signals on the SPI cables and I found that MOSI data is sent, but no response comes out on the MISO cables(only zeros). What could be the reason? I've been trying to find a solution for 3 days, but I just can't find it.
bless you brother...i need it badly
Nice project, did you make any hardware modifications in CAN controller chip about voltage conversion to 3.3v?
no
Hi, Do you have one example with codesys ?
Can you please point me to a tutorial that taught you how to do all this? (if available)
I cannot find the libreray.
@@brio_tele271 how about, what to search for?
Do the connections change in rpi 4?
please can you give us the raspberry code
can you give me a link of the libraries that you used
i doubt for this circuit because arduino is 5volt and raspberry is 3.3volt logic level

I have had the same problem. My raspberry pi receives CAN messages but sends nothing. Did you manage to fix it?
Slt Bro
jai envie de faire la communication CAN entre deux PI, peux tu m`aider stp
dude none of those library exist and also can you please also add that notepad file
