Thanks lut worked great I would never have thought to use it for this

Maybe we should deprecate the muxN components in favor of mux_generic?
I think that there is some argument for this, one advantage is that it
is easy to make the mux bigger without all the pin names changing.
The downside,
I have one suggestion for this problem.
Classic Ladder.
Hal is great, but when it comes to doing logic, at that level, ladder
logic rules.. :-)
Life is short, learn ladder.

For this application that might well work, though it would depend on
the nature of the signal being manipulated.
CL would be a poor choice for step signals, as CL is not

Sorry, I appear to have been labouring under a misapprehension for
classicladdr_rt runs in the servo thread like any other realtime module.
This is an important information.
That means that the CL logic is processed every servo period isn't it ?
This point is missing into the documentation (as I know) .

I have 2 input devices that need to write to 1 pin
I want them to be able to select witch one writes to the pin from a Mcode
that can set the select pin
Pin 0 is connected
The lut5 component can be used to implement arbitrary functions of up
to 5 bit inputs. Since the kind of lut you need has just three bit
inputs, it is a good candidate for being implemented by lut5.
