Hello everyone... I would like to learn more about Arduino and Can Bus. I would like to learn the ids part... I have a Peugeot and the Arduino nano with the mcp2515 board can be connected to the car's modules. but where can I start learning about the commands for entering and changing modules? discover the ids... is there any tutorial where I can gain this knowledge? I would like to change a parameter in the injection, what software do I use or how do I identify the ids and commands? I don't know if you understand me. thanks
You will get a lot of questions for this. You might want to "make your own stand-alone CANBUS for educational purposes" to attract better questions and answers.
Here's a web site I enjoy for many Arduino peripherals. He touches on canbus in this:
https://dronebotworkshop.com/arduino-uno-r4-minima-wifi/
It is illegal, to change motor parameters, in lots of countries.
I will read the site, thank you!
I just want to activate stability control on injection, not for commercial purposes.
You think You know that better then the motor designer?
What does it have to do with me activating the stability control or wanting to learn how to work with Arduino and Can Bus when I know more than an engineer??? I believe you are opining on the wrong topic friend! If you don't contribute, don't say anything because your question doesn't make sense!
This is the best way to introduce and proceed through your project. No one wants to participate in a probably deadly, potentially illegal, possibly damaging after-market modification.
I want to learn, try to at least learn... do you know when the sketch loads? Then it opens the serial monitor where you can send the commands... is there any tutorial that teaches about these commands that can be done? and thanks for the link above, very interesting... where can I find more?
Watch a bunch of YouTube videos on MCP2515 Arduino. (and read their linked web page)
Some of them show a stand-alone bus with point-to-point communication transferring data.
Most of the videos show fully operational CANBUS monitor and watch their dials work.
A few of the videos say "if you put the wrong windshield-wiper-speed packet in the wrong place your engine will be destroyed"... I listen to the last one more than the first two.
When I open the Arduino software, where there is the sketch, if I go to file, examples, Arduino-mcp2515 and can read, there I would read the car's can bus? After loading the sketch, where would I see the codes? on the serial port or do I need separate software?
You would need an Arduino CANBUS interface.
Indeed.
And most everywhere you would need to inform the vehicles insurance company if you are 'modifying' the vehicle.
Was there not a time when the microcontrollers in Arduinos had a 'not for use in motor vehicles' clause ?
Atmel/microchip still has it on their datasheets.

So an insurance company are very unlikely to approve of using one to modify a vehicle.
And the department of transportation... do not want things littering the motorway.
So... post #2...
And all will be well.

I'm not asking about car insurance. You don't know if I have insurance or not or where I live,
they just judge. because he has knowledge in judgment and not in Arduinos! I just gave an example...
I can pay to remap the injection, but that's not the case either!
a lack of understanding generates judgment and is always wrong!
Thank you for the advice but I'm trying to learn how to work with Arduino and not with a car insurance company.
You started your post wanting to learn about Arduino and Can Bus.
Many exeperienced engineers would suggest that tinkering with the internals of a vehicle is hardly a beginners topic.
As for the insurance and illegality issues its entirely appropriate that these are pointed out, in paricular if its road used and carrying passengers, as the OP may not be aware of the issues.
For sure, and no doubt carried out by experienced and certified engineers ?

engineers were born knowing! that's interesting!!! they never started from scratch!
Again, stop fantasizing about things because you're just another lunatic!
passenger transport? where was this said here??? you got it out of your head and say absurd things without knowing it!
I would be ashamed and stop responding because he is pretending to be another lunatic who is fantasizing and lying because he is talking about something that has not been said here. just in your head!
