Any thing is (im)possible with software...
You can look into the O'scope java code to find where values
are converted for plotting and stick your conversion formula
in there. I'm sure that exercise will lead you to the code
that does a full channel display which you might clone in
order to add a third channel. I suspect you will have to
change the TOS message structure to include that third data
stream, but that is not too difficult if you've been through
the TOS tutorials.
I have some difficulty understanding what you are doing now.
The included code doesn't send any data to the host. Presuming
that you are sending in whatever you are working with, what are
you using to receive on the host end? What exactly is producing
values from 10 to 1005? Can you post your host side conversion
code?
