fustration usd axes card

[jmig]

I received my new PIC chip today. Installed it and she came right on. Hooked the roll and pitch axes. They were rock solid. Haven't connected any buttons back as of yet.

I use the Open Cockpits USB Axis card with no issue. As mentioned you do need to connect a dummy load to any unused axis and diodes are often required on joystick buttons for purely electrical reasons (as mentioned), but no it isn't mentioned in any of their manuals. You have to remember that these guys design and build these interfaces for next nothing compared with more commercial entities but after sales support tends to suffer. Like a lot of things with this hobby, you need to figure it out for yourself sometimes. Hence the reliance on forums such as this one.

Also are you using FSUIPC for axis control? Jittering axis is often a symptom of having the axis assigned in FS as well as FSUIPC. You need to delete the FS assignments in order for FSUIPC to adequate handle them. If you aren't using FSUIPC then forget what I said.

Good luck,

Ken.

Hi Jmig

I take it you got the axis working stably. Well done mate. Glad to hear it as the card is really good, even if their documentation is 'basic'.

If you do need the dummy load, attach a 5k resistor across pins 1-2 and 2-3 of each of J3 - J7 which you are not using. The resistor pair act as a 10 potentiometer set to 50% of travel.

As far as the diodes goes I decribed this in my earlier post. Naturally the diodes are completely irrelevent when it comes to attaching the analogue axes - they are only needed to prevent backfeeding when multiplexing the buttons.

This is good stuff. I agree with efecemelci that this thread should be moved to the opencockpits forum for continuity.

Rotten (LOL that sounds funny) which pins do you attach the dummy load to? I have already blown that chip once. It is just too expensive with freight to blow it again.

THe reason I pretend to fly is the NZ CAA don`t take kindly to pilots with asthma (hence the Rottenlungs moniker) - I could get a PPL , but without the commercial aspect I can`t quite afford it!

James (rottenlungs!). I really recommed getting your head around SIOC. Once it's happening you can do enormous things with your components not normally available within FS itself. Have a study of the french simucockpit site for some good initial explanations, then pinch code from other users at the Open Cockpit forum to adapt to your use. It works, and I'm really not sure how but I muddled through.

Nico Kann's site http://home.planet.nl/~nwkaan/ is a good place to get the basics of SIOC. He is very knowledgeable on the subject and has written a manual.

Hi, yeah I had come across Nic Kaan`s site before - it looks like he knows his onions. Is he the guy that did the LDS767 interface (lekseekon?) too? I`ve been experimenting with that lately. What I`m not sure of is if SIOC is actually compatible with the USB axes card - because it is essentially a joystick controller I don`t think it is..?

Cheers

Not sure but I had a recollection it was compitable. I know it recognises axis connected to the USB expansion card which has 4 axis. I recommend searching the Open Cockpits forum for example code to operate axis.

From what I can gather from oc.com, the USB axes card isn`t compatible. The USB expansion card is purely to interface the other (SIOC compatible) cards and is, as far as I can tell, totally different to the axes card I have.

However, I intend to upgrade to the full OC stuff, as the next stage of my pit is to interface some outputs, I want the warning lights to work next.

The USBAxis card is NOT compatible with SIOC or IoCard. It is purely a joystick interface with windows.

Interesting however, my USBAxes card shows up as IOCard or something close in the Game controllers applet.
