pyvcp and gladevcp using same signal halui.axis.x.minus was created by nicokid

Hi,
I would like to live together pyvcp and gladevcp (I do not know if it's a good idea).
I have a jog button that does the same thing in both interfaces: x-minus.
So in my postgui HAL file I have inserted these lines:

net gvcp-jogxminus halui.axis.x.minus <= gladevcp.jog_x_minus
net my-jogxminus halui.axis.x.minus <= pyvcp.x-minus

But rightly I get this error:
Pin 'halui.axis.x.minus' was already linked to signal 'gvcp-jogxminus'

I have tried different combinations without success. Is there a way to share the "halui.axis.x.minus" signal?
Any help will be appreciated.

Nicola.

You use the or2 like this:

#put this line with the rest of your loadrt lines.
loadrt or2 count=1 

#put this line with the rest of your addf lines, the order of the addf lines matters.
addf or2.0  servo-thread

net gvcp-jogxminus <= gladevcp.jog_x_minus => or2.0.in0
net my-jogxminus <= pyvcp.x-minus => or2.0.in1
net jogxminus <= or2.0.out => halui.axis.x.minus

I had tried or2 but without success. I always have some understanding problem with the HAL pin :blink:

Now your code works perfectly

Thank you guys.

Nicola.
