Phidgets, Recall Switch and Sixpack

Hi fellow builders,

This weekend I took the opportunity to finish the Capt side sixpack annunciators and recall switch.

Now I'm wiring and testing using Phidgets, PMSystems and FS2Phidgets, but I've hit some problems that some of you may have encountered and have a solution for....

Basically what happens is when a sixpack annunciator (controlled by PMSystems) is lit, then when I press the recall switch, I want all the sixpack annunciators to light up (while the momentary recall switch is pressed), then when released it should light up any annunciators that indicated a problem condition and extinguish all others.

I tried doing this by assigning (using a LED64 Phidget) the various annunciators in the phidgets.txt file used by PMSystems. I then assigned all the annunciators and the recall switch to one common circuit under FS2Phidgets and made it "Push to Test".

So far so good. When I press the recall switch every annunciator lights up:cool: and when I release the switch it all goes dark. That is fine.

BUT when PMSystems is started and the sixpack indicates a problem eg "FLT CONT" when the Yaw damper is turned off for example , and the right annunciator lights up, I then press the recall switch and find that everything lights up as expected but when I release the switch everything goes off including the problem indication "FLT CONT" ...which should remain lit. Now when I turn the Yaw Damper back on and the off to re-light the annunciator, it doesn't work at all... PMSystems loses the plot...and toggling the Yaw damper switch only momentarily lights the "FLT CONT" like for about a microsecond or not at all...

When I operate without using FS2Phidgets however the annunciators work fine though PMSystems however I cannot then get the annunciators to light when pressing the recall switch as happens in the real aircraft :-( as I've lost the ability to assign a circuit via FS2Phidgets...

To me it seems like FS2Phidgets is somehow interfering with the PMSystems logic once the use of the circuit to light all the annunciators is triggered by the recall switch being pressed....

Is there any way around this problem or can I do a similar thing as the circuit function in FS2Phidgets via PMSystems...

Hope to hear from some of you...

Cheers,
Luke

Hi Alan and other fellow builders,

I did some further testing of my recall panel set up by removing FS2Phidgets software from the loop and just using PMSystems thus forgoing the "test" function via the circuit fuctionality I had created using FS2Phidgets...and I finally got it to WORK!!! just through PMSystems. :grin:

In the logic file for the 737 I find:

if recallswitch then
sixpackfltcontdisp = 0
sixpackhyddisp = 0
....
....etc
else
sixpackfltcontdisp = sixpackfltcont
sixpackhyddisp = sixpackhyd
....
....etc
endif

So I found all I had to do was set sixpackflcontdisp, sixpackhyddisp and all other sixpack...disp variables = 1 rather than 0 as in the logic file in the recallswitch code. I also found that I had assigned the wrong variable to my phidget outputs...the non "disp" ones i.e sixpackhyd instead of sixpackhyddisp....

When I rectified the above an I tried it....it worked like a charm. Very nice !!! Pressing the recallswitch lights everything up and releasing it leaves the items that were indicated as cautions lit up while the others are extinguished :D

Cheers,
Luke

Excellent. I am going to try it!

Cool Alan,

I hope you have success and let me know how well it works for you

Cheers,
Luke
