Flight Director Offsets?

[guenseli]

Hello Mr. Dowson,

I try to programm a switch panel.

Seems very simple, but somewhere I have made a mistake:

Switch up is FD ON

Switch down is FD OFF.

For the Up Position I have entered

Offset Word Setbits

2EE0 with Parameter 0001

This is working...

For the down position I have entered

Offset Word Clrbits

2EE0 with Parameter 0000

But this doesn't work...?

Whats wrong here?

Thank you very much!!!

Edit:

Is there a possibility in the same way for the Autopilot?

I just can find a master switch as toggle.

But is there a function for Ap on and Ap off?

That doesn't work because you told FSUIPC to "clear no bits": there are no bits in 0000 -- they are all zero!

You presumably want to clear the same bits as you set, so the parameter should be 1, just as for the "ON" action.

Anyway, you are really using the wrong controls entirely. The "SetBits" and "Clearbits" facilities are for operating on individual bits in an offset, like those lights in offset 0D0C. You just want the plain "Offset Word Set" control, with value 1 for on and 0 for off. That control simply writes the parameter to the offset.

You know there's a regular FS control for the FD too? It is called "TOGGLE_FLIGHT_DIRECTOR". Of course it is a toggle, so suits a button rather than a switch.

No, not separately. But you can use "Offset Dword Set" with offset 07BC, and parameter 1 for on, 0 for off.

As allways:

Many, many thanks!!!

Both explanation of you work as I wanted it to do.

Perfect!
