Hi

This works for switching between Standby and Squawk mode Charlie but I cannot get it to work for Identing?

Any help appreciated.

Thanks

Ralph

Maybe a bug in the software no one has found until now? Has anyone asked them? (SB)

The ident actually does work but for some reason the light does not flash.

I tried it out 1 night with atc & they confirmed ident working.....

On the 0x7b93 offset, have the parameter set to 1 on the key/button press. It will automatically return to 0 after it Idents.

Hi,
Does that mean you have to reset it to x01 in FSUIPC after each ident? Not that we are asked to do it that often but it seems a moderate pain in the ***?? And can anyone else confirm it works in flight, even if the Ident does not flash on the gauge?

Thanks for the help, guys. I love this forum!

Note that there are two offsets involved:
http://squawkbox.ca/doc/sdk/fsuipc.php

7b93, used to "push" ident, by setting it to 1 (as tunatuk described), no resetting needed (that is done by fsuipc).

7b92, that becomes 1 if "ATC hits us", you have to set this back to 0 if you want to detect another hit...
You can use this offset for a flashing led indicating ATC activity. I do it like this: if it becomes 1 I lit the led and I will let it go out after 0.2 seconds.

I can confirm that the SB3 SDK in FS9 works perfect. I'm more worried about the still missing support for SB4 in FSX, no Simconnect interface yet.

For SIOC users, attached is my FS9/SB3 code:

I can confirm that the SB3 SDK in FS9 works perfect. I'm more worried about the still missing support for SB4 in FSX, no Simconnect interface yet.

I've written to the SB4 authors asking for this to be resolved several times. Each time they apologise for not getting to it and promise to look at implementing a solution. All I am seeking is something along the same lines as the PTT (and PVT) implementation -- registered Windows messages, which can be sent from an assignment in FSUIPC locally or via WideFS.

I hope to hear from them soon ... I was thinking of trying on-line ATC, and actually installed SB4 for use in my cockpit, but the transponder issue stopped it dead. I'm not about to have horrid gauges on my outside view, nor mice in the cockpit! ;-)

......... nor mice in the cockpit! ;-)

Pete,

I use peanut butter on the traps to keep the mice out of my cockpit. ;)

Works great.

best,
