Anyone using a CANBus card with openSUSE? We will soon have a MobilEye device that we want to test integrating with our system. And it speaks CANBus. We are on our own to provide the CANBus card. So something that is known to play nice with Linux/openSUSE is what we are looking for. So any suggestions or experiences are welcome.
A canbus is based on rs232 at least in the microcontrolers I use it is. There are level shifting devices that work with usb that are available. Don't know about software that's available though.
Let me try to understand. The card you people are talking about is a card for the computer, not for the car, and allows a computer to at least read what goes on the car's CAN bus, right?
Understanding is good, a very laudable goal. I'm with you 110% there.
I know nothing about the aforementioned card, never heard of it, so can't really speak to what it's for or what it does. But CAN/OBD devices are normally connected to a vehicle so they can (at minimum) collect data about the vehicle from sensors installed (mostly, but not necessarily) during manufacture. They're useful because they can provide information about the functioning of the vehicle they're installed in and even about the physical environment the vehicle is currently in. Originally the OBD system (now part of CAN), an open standard, was meant to optimize the performance of a vehicle (in real time) in order to minimize pollution and increase fuel efficiency. It's the system which can cause your car's "Check Engine" light to go on. Of course all of that impossible to do any of that unless the device is connected to the car. The original open standard doesn't preclude additional, proprietary functionality to be built into the same system.
To be precise OBD and current OBD2 standards use several busses CAN being one of them. You can get cheap usb and bluetooth OBD2 readers. best regards Dave P
Yeah, my post above was meant only as brief intro. There could be several volumes written on the topic. I was definitely speaking in generalities definitely at the brink of my comfort level. I've purchased three of those "OBD2 readers".... (For people looking for more info on them or to buy one, they're more often called "OBD scanners".) One tip I'd pass along, before buying, check the operating temperature range. One of the "scanners" I bought died in the first year I had it, most likely due to my running it on a really hot summer day... in the mid-30s C. The AC didn't help it because I'd mounted it behind the dashboard (hidden away, attached to a Raspberry Pi). However, the only website listing operating temps of the scanners they sell which I've seen is scannet.com (IIRC the URL). They sell higher-quality scanners (said another list I was on), their prices reflecting that slightly. And no, I have absolutely no financial interest in that site... or in any other part of that whole industry. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
