Cannot Addf a custom component. (fails with function not found)

I don't understand this error.
I wrote the attached custom component to decode a MPG I use.
It compiles fine, loadrt works perfectly and the components pins can be seen in halshow at this point
but when I use addf, it raises an error
It does not matter if I use names= or count= when using loadrt
Any ideas would be really appreciated. I tried decoding this in hal but gave up as its very messy.

at the command line
halrun
loadrt pendantjog names=mypendant
show funct
will probably answer the question

I did that a few years ago, based on the work here github.com/KurtJacobson/RF45-CNC/tree/ma...HAL%20Components/MPG does make the whole mpg setup easier.

But if I do the same thing with say o2, I get an address. What causes i tto be missing?

I just compiled an dloaded your comp and was just going to compare kurt's to yours. You beat me to it.
All the best, makes hal alot more manageable.

The MPG is fine as I did it in Hal 7-8 years ago for this same device but I wanted to enable the Plus and Minus jog buttons that also have a third button to select between low speed and high speed jogging. That was very difficult to do in hal.
