Good to know.

What is VSCP?

I haven't worked with any of the CAN bus interfaces used here.
I have heard complaints that the XAC3 has a hard time keeping
with a 1MB/s CAN bus.

How's your, or anyone else reading this, experience been with an
LPC CAN device? What kind of CPU loading can be expected
for a device having to transfer say a few hundred bytes every
half-second during normal operation, but say several thousand
messages-per-second in a debug mode (eg. acting like a data
acquistion device a 1KHz sample rate).

With the DSP work I've done, I use the uCOS-II RTOS. I've got a
port running on the LPC devices, and I have the port correctly
nesting interrupts (which none of the Micrium web site uCOS-II
ports do). I figure when I implement the CAN interface to the
encoder, I'll build on that work.

Its a fun place to work and live, but very dependent on NSF
funding. We just lost 15% of our required budget due to NSF
cuts, and that resulted in a number of people losing jobs.
This unfortunate situation is one reason why I need to start
learning more about the CAN bus.
