Hi Ray,
I guess you weren't pasting wrong after all... Looks like that by formatting the formula with pretty colors I also disabled any updates of the label. How silly.
Anyway, this led to a better solution... I figured out how to get the same numbers right into a cell in the spreadsheet. Wow... it only took 3+ years to figure that one out...
So here you go... I changed some names and added notes about this being useful for RPM and voltage based measurements as well.
I agree about the function in ECU... it would also be great if drone-controls were providing tools and support for their product (Quatos) instead of relying on volunteers like me.
Cheers,
