[QUESTION] How to set LVAR

[gleclere]

Hi Maarten,

I'm wondering if it's possible to set LVAR such as A32NX ones described here https://github.com/flybywiresim/a32nx/blob/master/docs/a320-simvars.md

More generally, where can I find some documentation about the way the code should be written in type condition events?

Thank you for the great job you're doing.

Maybe this is the solution:

#15

[gleclere]

Thank you @SQLSammy

I probably found a part of the answer in #14 "Conditional triggers can set and get global variables", but it doesn't work for local variables.

For instance, I wish to change the MFD range of the A32NX using the encoder 3:

{
  "index": 3,
  "event_up": {
    "type": "condition",
    "event": [ "{% set mfd_range = data.get_local_variable('A320_NEO_MFD_RANGE_1') %}",
                 "{{ data.set_local_variable('A320_NEO_MFD_RANGE_1', mfd_range + 1) }}"]
  },
  "event_down": {
    "type": "condition",
    "event": [ "{% set mfd_range = data.get_local_variable('A320_NEO_MFD_RANGE_1') %}",
                 "{{ data.set_local_variable('A320_NEO_MFD_RANGE_1', mfd_range - 1) }}"]
  }
},

Since you linked the simvars documentation of the FBW A320 I guess you want to directly change a simvar with an encoder. In this case you should be able to use the get_simvar_value and set_simvar_value. But there might be a problem with the way python-simconnect returns None when you request a simvar that is not in it's list. I will do some research for this.

{
  "index": 3,
  "event_up": {
    "type": "condition",
    "event": [ "{% set mfd_range = data.get_simvar_value('A320_NEO_MFD_RANGE_1') %}",
                 "{{ data.set_simvar_value('A320_NEO_MFD_RANGE_1', mfd_range + 1) }}"]
  },
  "event_down": {
    "type": "condition",
    "event": [ "{% set mfd_range = data.get_simvar_value('A320_NEO_MFD_RANGE_1') %}",
                 "{{ data.set_simvar_value('A320_NEO_MFD_RANGE_1', mfd_range - 1) }}"]
  }
},

For more information about how to write code for the condition events. I use jinja2 to parse and execute the template https://jinja.palletsprojects.com/en/2.11.x/templates/
To see which functions you can call on the data object you can take a look at the https://github.com/maartentamboer/X-Touch-Mini-FS2020/blob/main/conditionalrunner.py file

I've been looking into this and I'm not fully aware what an LVAR is. But I guess that it is a local variable that stays inside of the simulator / aircraft code. With that I was unable to connect to them using the simconnect API. I used the latest experimtal build of the FBW A320 and the simconnect API gave me this:

SIMCONNECT_EXCEPTION_NAME_UNRECOGNIZED
SIMCONNECT_EXCEPTION_UNRECOGNIZED_ID: in (b'A32NX_NO_SMOKING_MEMO', b'Bool')

also tried with the L: in front of it

SIMCONNECT_EXCEPTION_NAME_UNRECOGNIZED
SIMCONNECT_EXCEPTION_UNRECOGNIZED_ID: in (b'L:A32NX_NO_SMOKING_MEMO', b'Bool')

Hi,

I've been able to use some of LVAR variables of the FBW 320NX thanks to the Mobifligh WASM module.
You'll find som info here on how to use X-Touch-Mini-FS2020 with Mobifligh: https://pastebin.com/fMdB7at2 (with a sample config file).
Here is a list of the commands managed by mobiflight : https://docs.google.com/spreadsheets/d/1jTXlcHaJWx0B7TB63Pmma7bKwpxsxXJO6EJ3ECt7zpc/edit#gid=172455454

Note everything is not available, as some commands use "HVAR" variables. I don't know the difference between LVAR and HVAR.

Personnaly, I recently move from X-Touch-Mini-FS2020 to SPAD.NEXT, to be able to manage two X-Touch at the same time (and to gain the benefit of a UI tool to setup the commands). But I keep an eye on X-Touch-Mini-FS2020, I might switch back some time ;-)

@gleclere funny, we've recently been in touch on "Flight Simulator 2020 France" facebook group :-)

[maartentamboer]

#41 has changes so the mobiflight WASM module can be used in conditional triggers. The config is really complex. So I will investigate adding a feature for using the encoder as a selector switch. Since these selector switches are quite common in aircraft.

[maartentamboer]

Release https://github.com/maartentamboer/X-Touch-Mini-FS2020/releases/tag/v1.3.0 is now available. This release can set the range using conditional triggers and the mobiflight wasm module. I've added it to the config_a320.json in the release.

Hello,
I tried your new version and the above example for MFD_RANGE, it worked for me, great.
For testing I played a little bit with a statement like
{
"index": 8,
"event_press": {
"type": "condition",
"event": [ "{% set myvar02 = (data.get_global_variable('MFD_RANGE')) %}",
"{{ data.print(myvar02) }}"
]
}
just to print out the value to the console, also working great.
I jjust have no idea, why/how this 'MFD_RANGE' works. I cannot find any hint where this variable comes from.
I was looking for 'A320_NEO_MFD_RANGE_1' and always get the 'None' returned.
The reason why I am asking is that I want to have a similar thing for the button left to the range button, the MFD_NAV_MODE button.
There are 5 seperate events:
A320_Neo_MFD_NAV_MODE_1_LS / ...VOR / ...NAV / ...ARC .../ PLAN
I am looking for a variable that shows the state of this button.
I tried with A320_NEO_MFD_NAV_MODE_1, but as expected only 'None'...

Any ideas?

Thanks for your great work.
Frank

If I understand correctly from my playing around last night, the MFD_RANGE is an internal variable. You can set it to whatever, introduce your own etc. And you need to use the MobiFlight implementation of the NAV_MODE.

It's easy from there, I've just implemented NAV mode myself:

    {
      "index": 2,
      "event_up": {
        "description": "MFD NAV MODE - Clockwise",
        "type": "condition",
        "event": [ "{% if data.get_global_variable('MFD_NAV_MODE') == 0 %}",
                     "{{ data.trigger_event('MobiFlight.A320_Neo_MFD_NAV_MODE_1_VOR', 1) }}",
                     "{{ data.set_global_variable('MFD_NAV_MODE', 1) }}",
                   "{% elif data.get_global_variable('MFD_NAV_MODE') == 1 %}",
                     "{{ data.trigger_event('MobiFlight.A320_Neo_MFD_NAV_MODE_1_NAV', 1) }}",
                     "{{ data.set_global_variable('MFD_NAV_MODE', 2) }}",
                   "{% elif data.get_global_variable('MFD_NAV_MODE') == 2 %}",
                     "{{ data.trigger_event('MobiFlight.A320_Neo_MFD_NAV_MODE_1_ARC', 1) }}",
                     "{{ data.set_global_variable('MFD_NAV_MODE', 3) }}",
                   "{% elif data.get_global_variable('MFD_NAV_MODE') == 3 %}",

                     "{{ data.trigger_event('MobiFlight.A320_Neo_MFD_NAV_MODE_1_VOR', 1) }}",

                     "{{ data.trigger_event('MobiFlight.A320_Neo_MFD_NAV_MODE_1_LS', 1) }}",
                     "{{ data.set_global_variable('MFD_NAV_MODE', 0) }}",

      }
    },

One question I have myself, just trying to implement the radio - even though it says tested on the WASM Events list, I'm getting no response with this code. Any glaring obvious reason I'm missing here?

      }
    }

[TheJAG]

Too quick - apparently the FBW team fixed the default call. So we can just use:

    {
      "index": 8,
      "event_up": {
        "description": "Radio - Increase frequency",
        "type": "condition",
        "event": [ "{% if data.get_global_variable('RADIO_INT_DEC') == 0 %}",
                     "{{ data.trigger_event('COM_RADIO_WHOLE_INC', 1) }}",
                   "{% else %}",
                     "{{ data.trigger_event('COM_RADIO_FRACT_INC', 1) }}",
                   "{% endif %}" ]
      },
      "event_down": {
        "description": "Radio - Decrease frequency",
        "type": "condition",
        "event": [ "{% if data.get_global_variable('RADIO_INT_DEC') == 0 %}",
                     "{{ data.trigger_event('COM_RADIO_WHOLE_DEC', 1) }}",
                   "{% else %}",
                     "{{ data.trigger_event('COM_RADIO_FRACT_DEC', 1) }}",
                   "{% endif %}" ]
      },
      "event_short_press": {
        "description": "Radio - Toggle between whole and decimal values",
        "type": "condition",
        "event": [ "{% if data.get_global_variable('RADIO_INT_DEC') == 0 %}",
                     "{{ data.set_global_variable('RADIO_INT_DEC', 1) }}",
                   "{% else %}",
                     "{{ data.set_global_variable('RADIO_INT_DEC', 0) }}",
                   "{% endif %}" ]
      }
    }

For radios its easier
{
"index": 8,
"event_up": "COM_RADIO_WHOLE_INC",
"event_down": "COM_RADIO_WHOLE_DEC",
"alternate_event_up": "COM_RADIO_FRACT_INC",
"alternate_event_down": "COM_RADIO_FRACT_DEC",
"event_short_press": "{alternate}",
"event_long_press": "COM_STBY_RADIO_SWAP"
},

Thanks for that mate, great stuff.

One more, I'm having an issue setting the Captain EFIS for the ILS - is the following the right way to make a single call to MobiFlight?

    {
      "index": 2,
      "event_press": {
        "description": "Trigger CPT EFIS LS",
        "type": "condition",
        "event": [ "{{ data.trigger_event('MobiFlight.A320_Neo_PFD_BTN_LS_1', 1) }}" ]
      }
    },

[maartentamboer]

If you want to fire off a single event you can just place the name of the event:

    {
      "index": 2,
      "event_press": "MobiFlight.A320_Neo_PFD_BTN_LS_1"
    },

Some events have an option of passing a value with them, for those you can either use the manual event or the condition event.

[TheJAG]

That makes way more sense, thanks @maartentamboer . This does throw a warning "WARNING: Event MobiFlight.A320_Neo_PFD_BTN_LS_1, was not found in simconnect list. Using a manual binding". I'm assuming this is fine (edit: should've set "type" to "manual" to suppress this message) - however I'm not getting the expected result. I was hoping to control this button but so far without success.

Is there anything I'm missing?

Hello,
I tried your new version and the above example for MFD_RANGE, it worked for me, great.
For testing I played a little bit with a statement like
{

}
....

Thanks for your great work.

Is it possible that you read and print sample has some missing or wrong brackets?
Is it possible that you post a real working sample?
