3 state button emulation and startup sync

[Francky63]

I need to emulate a 3 state switch(as in Cougar TQS DOg fight switch). As you probally know this is fixed in Falcon or in Tusba but the only solution for other programs is your application. Thia state are often used (especially in flight simulator application to determine the MODE) On the HOTAS usually you have a ON OFF ON switch where the software need a On ON ON switch. What i would like to do is to use the pressed button state for to remap the two ON buttons on vJoy and release button to remap OFF state on a vJoy button, i mean: you have UP MIDDLE DOWN position on the HOTAS usually you have only UP & DOWN state mapped on a Joy Buttons. My target is to have (e.g) UP vJoy button 1, MIDDLE on vJoy Button 2 and Down on VJoy button 3. Of course only one of them at time is on. I'm not able to do it with Joystick Gremlin UI i try with remap and condition, action pressed and release (that it look not working) but nothing. What i suppose to do is put On btn 1 when UP is pressed and Off btn 2, Put Off btn 1 and on btn 2 when UP is released (MIDDLE position emulation), Put On btn 3 and off btn 2 when DOWN is pressed and at last ... put off btn 3 and on btn 2 when DWON is release.

I solved it with the attached script where i insert also a problem for IDLE detent and engine start for Warthog ( when button is released the engine should be started and i need to rise up a button ...

This it solve all my needed except button initialization i need to put MIDDLE vJoy related buttons to ON when Joystick Gremlin is enabled i think i need something like this: vjoy[1].button(g_3_STATI1_MID_OUT_btn).is_pressed = True that should be executed at startup, but i don't know the right syntax and where to put it

I Think an synchronization option between input devices and vJoy output devices could be a useful feature in Joystick Gremlin Now if i start with joy button X pressed mapped on vJoy button Z, Z it stay OFF until a new source button state change

after I read one of your previous answers about press and release condition issue i found how to do it with MACRO.... Never mind ... but i would like to know how to initialize the button state via script and if could be an enhancement

[WhiteMagic]

I don't have a device with three state switches but I'm assuming that to Windows they appear as three independent buttons right? This is probably a case where using a finite state machine ( https://en.wikipedia.org/wiki/Finite-state_machine ) will make life much easier. Gremlin actually has a simple implementation of those as it's used to handle button states etc. I'll see about writing your example up using that as it probably should make your life much easier.

As for synchronizing physical and virtual buttons for initialization I think for a script something along these lines should work:

import gremlin

joy_proxy = gremlin.input_devices.JoystickProxy()
vjoy_proxy = gremlin.joystick_handling.VJoyProxy()

vjoy_proxy[1].button(1).is_pressed = joy_proxy[1].button(1).is_pressed

If this is part of a module loaded by your profile this will run whenever Gremlin is activated. What it then does is read information from the physical joystick and writes it to a vJoy button.

This should mostly work, however, due to the way joysticks work, i.e. they send information about state change as opposed to one asking them for their state, this can at times not work if there hasn't been a change recently. I found this mainly to be an issue with axis which is the reason that one can set their initial values in the settings tab.

Hi, I'm running those code, vjoy_proxy works good, but the joy_proxy variable report the exception:

Traceback (most recent call last):

Could you give an example code how to fix it, thx

[WhiteMagic]

You can't use an integer index to access devices. The JoystickProxy requires the device's guid to be used, see https://github.com/WhiteMagic/JoystickGremlin/blob/r13/gremlin/input_devices.py#L392

Also how tristate buttons appear probably depends on the specific hardware implementation, could also just be 2 buttons.
