This is cool because it lets us easily integrate the system into LAVA.

It *is* cool. Are setup instructions captured somewhere on a wiki? This would be useful to many people.

Aye. Here are the preliminary ones: https://docs.google.com/a/linaro.org/document/d/1x80d8W0sw_aD4hZJZ1bqG4VolDT...

I'm still working out the VI. The basic protocol will be:

1. Open a TCP/IP connection to the box. 2. Send 's' to start the measurement. 3. Send 'e' to end the measurement. 4. Send 'r' followed by a read. The read will return the total current of the last measurement. 5. Send 't' followed by a two reads. The first will return the number of records (timestamp and value) the second read will return the records (thanks Andy Doan for communicating TI's want of this).

...or something like that. Its very easy to reconfigure the VI into a variety of modes, so its completely feasible for people to write there own and run them as well. You can even do remote development (though having a remotable reset of the whole system will be cruicial).

Regards, Mike

Cool. Can I see your code?

Talking like this in terms of network protocol design scares me a bit btw :-) What do you mean by a 'read' here? Is it just newline delimited?

5. Send 't' followed by a two reads. The first will return the number

of records (timestamp and value) the second read will return the records (thanks Andy Doan for communicating TI's want of this).

Ah, this protocol is part of the VI itself? For some reason I assumed it would be a separate daemon that poked the NI stuff using COM or whatever.
