Hello Peter, It works and I can read the value now. How can I scale this correctly? I have a 0-5V input and need my GladeVcp bar to show Maximum at 5V input but at 5V input it does not show maximum. I looked at the 'scale' command but all examples and descriptions I could find are for outputs and not for inputs.
Here is what I did: *net spindle-load hm2_5i25.0.7i76.0.0.analogin0 and connected this to the Glade panel bar.* *Could you explain how to use 'scale' correctly to scale this input to read 5V as maximum value for the Glade bar if needed at all.* *Thanks,* *G21* On Wed, Dec 28, 2016 at 12:00 PM, Jan Bos <rappyrip...@gmail.com> wrote: > Thanks Peter, will free up these and try again.
