RE: CAN bus real-time sender and precise timestamp receiver tool

Both could be relatively easy to achieve with a dedicated interface from
Kvaser or Vector (and probably other suppliers, but those are two options I
have had a lot of experience with).
Although the devil is in the details of your requirements.

If it's just a matter of sending one (or a couple of) message(s) with a
fixed cycle time, and timestamping received messages with the requested
accuracy (higher accuracy = more expensive interface ;-) then it's something
that you could develop in half a day's time (if you know your way around the
provided APIs). If you need some real-time interaction between the stuff you
are sending and receiving, it may take a bit more work.

If you are using Linux, it's probably best to steer clear of SocketCAN and
go for the proprietary API for the implementation. On Windows, it will most
certainly go via the supplied API.

cheers,

Subject: [CANLIST] CAN bus real-time sender and precise timestamp receiver
tool

Hello

For one of our equipment, we need to realize performance test over the CAN
bus :
 - we want to send CAN messages at a frequency of 100Hz with a precision of
1ms to the equipment,
 - and also, to timestamp received CAN messages from the equipment at a
precision of 1ms.

We aren't able to do this with a "classic" USB-2-CAN interface because of
the latency of the PC.

Would you have any solution ?
