In truth I would much rather be shown what to look for over how to do it.

In that case, the neatest way to do this would be using www.linuxcnc.org/docs/html/hal/comp.html

And a file something like

component pmdx_demux "demultiplex PMD extended mode"

pin in bit charge-pump;
pin in bit in-# [4];
pin out bit out-# [8];
pin out bit out-#-not [8];

function _;
license "GPL";
author "andy pugh";

;;

FUNCTION(_) {

int offset = 0;
int i;

if (charge_pump) offset = 4;

for (i = 3, i > 0, i--){
    out(i + offset) = in(i);
    out_not(i + offset) = ! in(i);
}
}

Oh cool, another language to learn

I'll check out halcomp and see if I can decipher C code, that has always eluded me.

Thanks again Andy

Cheers
