How many "virtual" joysticks are there in FSUIPC?

[pilotjohn]

Is it 16 (64-79)? I'm trying to space my panels out. Thanks!

I think you can have up to 300  devices in total, virtual or otherwise, with 256-299 being reserved for VRI, and 0-15 for standard joystick type hid devices.

I'm specifically asking about the FSUPIC specific range that starts at joystick #64 (via offset 0x3340)? Based on the 36 bytes, it seems to be 9. Is there a way to use more somehow?

[John Dowson]

Offset 0x3340 only supports up to 9 devices, as you say. You can use offset 0x7F00 which supports up to 16 devices with 128 buttons.

@John Dowson Thanks... I tried to use 7F00 with the client libraries, but FSUIPC doesn't seem to be reacting to them.

Any thoughts on whether this is a client library or FSUIPC issue? Or me?

I posted a thread here:

I don't know...those offsets have been around for quite a while now, so I don't think it is an FSUIPC issue but I can check.
However, I am away from this afternoon, back next week, so it will take me a while before I can take a look at this in detail.
Keep me updated if you find anything, otherwise I will report back once I have checked that offset area (mid to end of next week),

So I used the client library's FSUIPCExampleCode_CS project to test this out by modifying the BC004_WritingOffsets example. 0x3340 triggers and logs, 0x7f00 does not. This removes StreamDeck and my original setup/code from the equation at least.

Sorry but I still haven't had time to look into this.... I am on holiday now, until the 3rd January, but will try and look further into this issue next week, when time permits. I will report back again once I have investigated.

Thanks... please let me know if you need me to test anything.

Ok, I have now looked into this. Offset area 0x7F00 is badly documented, and is for real joysticks not virtual ones. Basically it is a copy of the facilities provided at offset 0x03C0, but for joysticks with up to 128 buttons, not the facilities for virtual joystick buttons provided at 0x3340. I will correct the documentation.

So, for your original question:

For virtual device access via offsets, it is only 9 (64-72) and via offsets 0x3340 and 0x29F0. This provides access to 288 virtual buttons.

Sorry for the confusion, and the time taken for me to look into this.

Regards,

...and I won't be increasing this. Too many changes would be needed to support more, especially considering WideClient....I am afraid you will be limited to 9 virtual devices for external triggering.

Ugh, ok thanks for looking into it.
