I suggest you change the sequence:
var volatile byte gp2d02_0_vin is pin_a2
var volatile byte gp2d02_0_vout is pin_a3

No.
You could do a conditional compile for the functions required:
if (defined(gp2d02_0_vin) == true) then
function gp2d02_0_read is
...
end function
end if
or you could something similar within a generic read functions
case (idx) of
if (defined(gp2d02_0_vin) == true) then
0 : block
...
end block
end if
if (defined(gp2d02_1_vin) == true) then
1 : block
...
end block
end if
default:
....
end case
I think this way you should get it to work. And you get a decent api
for the use of the lib.
We should realy thank Stef for the conditional compile. I understand
people how studied computer sciences think it is horrible, but for a
practical guy like me it is very powerfull. If we only could have
marco's ;)
