100$ is an ambitious price target ...
I know. I was hoping my poking around the net had missed something obvious,
like an OBD-II dongle that happened to access the CANbus...
What do you folks use?
We also use PCAN USB adapters, which require the PEAK driver that's not in
Linux Mainline. If you'd like to use mainline drivers there are two USB CAN
interfaces from EMS Wuensche and ESD that support the latest netlink CAN
configuration interface and should work excellent out of the box.
Ok, that confirms my research. Those were the only two vendors I had found as
well. They are a bit out of my target price range, but if it's the right
tool...
I just sent a few questions to Angelina at EMS, we'll see how that goes. I'm
looking at the CPC-USB/ARM7 and trying to determine if I need the low speed
version or not.
There's also a low-cost USB CAN adapter (http://www.canusb.com) that is priced
at $99 on it's website. This adapter uses an ASCII protocol via an USB-RS232
adapter integrated inside the hardware. This adapter requires the slcan driver
from the SocketCAN SVN and some handling to switch the serial line discipline.
There's no real handshake nor flow control on the serial line ... but i know
people using it :-)
I've spent days poking serial ports trying to come up with the magical
combination of parameters to make them work. I'm man enough to admit it's not
my strong suit and I'll avoid it if at all possible. ;-)
Thanks for any pointers,
With hope that gave you some of them ...
Yes, definitely. Thanks again.
Jason.
