[Flightgear-devel] new kap140 - encoder problem

[Dave P. <ski...@mi...>]

Hi Roy,

I am re-posting this since I am unclear what to do to make your cleaned
up kap140.nas altAlert work.

It appears that /instrumentation/encoder/serviceable still has value
(none).

Everything in the new kap140 is working except the altAlert. It causes a
nil in numeric context error on the altDifference line because altFt is
nil since /instrumentation/encoder/pressure-alt-ft = "(none).

  altFt = getprop(encoder, "pressure-alt-ft");
  #print(altFt);
  altDifference = abs(altPreselect - altFt);

This even in the case of the c172p as well as in my edited version that
checks for autopilot power.

Is the new kap140 working for the c172p for you?  What do I need to do
to get the encoder initialized?

Kind regards,
