Cant get spindle RPM to display

Hi guys, can't get spindle RPM to display, i have noticed a few different examples in the postgui.hal but non seem to work, i just get a -0 in my rpm display, I will attach my postgui.hal and my main.hal and a screenshot of halshow. Hopefully it's something very basic.thanks in advance

     

One way:

in the main hal file add:


net spindle-vel-rpm hm2_[MESA](BOARD).0.encoder.00.velocity-rpm


in the gui hal file delete:

net spindle.0.revs  => qtpyvcp.spindle-encoder-rpm.in

and add:

net spindle-vel-rpm  => qtpyvcp.spindle-encoder-rpm.in

amazing it works thank you, just need to change it so its not a minus sign before the reading
