Add a power switch makes such a satisfying click. This cable will also work with anything that has a OBD-connector. If you want to read data or control your car, there's an OBD>DB9 cable available for you, this cable make easier to connect to OBD-connector and DB9-connector. What if I want to connect this shield to my car If your project is space limited and also don't need other fuctions except CAN-BUS, here is a Grove CAN-BUS module which is Arduino compatible, more compact and cost effective, please click here to visit its page. This document applies to the following version of products: Version With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device or data logger. This CAN-BUS Shield adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver to give your Arduino/Seeeduino CAN-BUS capability. It is commonly found on modern machine tools, such as an automotive diagnostic bus.
#CAN BUS SIMULATOR SOFTWARE#
It all depends on your electronics and software knowledge, building your own analyser and custom PCB is not that hard with beginner electronics knowledge.CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. I have personally made my own CAN bus analyser with a 72Mhz processor, which I would say is the minimum required to simulate a complete network. I would invest in a decent CAN bus analyser such as Kvaser.

I would avoid DIY and open source CAN bus devices such as Arduino as they are usually not fast enough to transmit and process up-to 100 IDs. Simulate this data exactly and there will be no issues. ECUs/Nodes don't 'talk' to each other, they're dumb, they simply monitor the bus for the data and make changes based on this data. Just remember the automotive CAN bus isn't really that complicated at all, each node simply transmits a number of IDs with up to 8 bytes of data.
#CAN BUS SIMULATOR PC#
I usually have the Engine ECU hooked up on a bench rig with all of the required sensors and actuators, I then hook this up to my PC using a USB-CAN device. Although after monitoring the live data enough it is not that hard to work the timing out. Or a specific Node will have to transmit first in order to wake up the rest.

Node 1 sends 'xxxxxxx', Node 2 will only then send 'xxxxxx1' then Node 1 continues to send the rest of the data. But some data acts as a call and response system, e.g. With 95% of the data transmitted it doesn't really matter about when exactly the data is transmitted it just needs to see it within a certain amount of time. The problem with this is that there can be timing issues with security and safety systems. You simply transit all of the CAN IDs and data that would be present on the vehicle. Number two has the benefit of saving space and eliminates the problem of missing hardware. The problem however is that there would be hundreds of errors unless you have every last electrical device hooked up as certain ECUs would be looking for sensors, actuators even light bulbs etc that were not present. Number one has the benefit of being 'real world' hardware, it is exactly as it would be in the vehicle. It really depends what you want to achieve and why. The benefit with this method is you can have gauges and graphs on screen. I prefer to use a USB-CAN transceiver and a PC that way I can write custom scripts and software to monitor the traffic and transmit at certain times under certain conditions. Monitor the CAN data on the vehicle in question so you know what data is required and then transmit this from your own device such as a PC, CAN bus development board etc etc. Wire up all of the required Nodes on the bench, for example this can be the Engine ECU, Instrument cluster, BCM, indicator stalk, rear convenience module etc etc. There are really two ways of achieving this.
