Using Keyboard for various Nav,AP, Comms Inputs

[Robertfm]

Came across this. Can this be done for flightgear seems an alternative to making Saitek type things to work. https://youtu.be/P2p6CHxMOl8

With some Nasal scripting it sure can be done.

An intermediate might be Multi-key commands (permalink).

I made keyboard controller for NAV1 radio :

Code: Select all

<PropertyList>
   <key n="257">
    <name>F1</name>
    <desc>NAV1 +/- 1 MHz</desc>
    <repeatable type="bool">true</repeatable>

     <binding>
      <command>nasal</command>
      <script>
       f=getprop("/instrumentation/nav[1]/frequencies/selected-mhz");
       mod=getprop("/devices/status/keyboard/ctrl");

       if(mod==0) {
    f=f+1;
         if (f>118){
           f=118;
         };     
       }

       if(mod==1) {
    f=f-1;
         if (108>f){
           f=108;
         };     
       };

       setprop("/instrumentation/nav[1]/frequencies/selected-mhz",f);

      </script>
     </binding>

   </key>

   <key n="258">
    <name>F2</name>
    <desc>NAV1 +/- 0.05 MHz</desc>
    <repeatable type="bool">true</repeatable>

     <binding>
      <command>nasal</command>
      <script>
       f=getprop("/instrumentation/nav[1]/frequencies/selected-mhz");
       mod=getprop("/devices/status/keyboard/ctrl");

       if(mod==0) {
    f=f+0.05;
         if (f>118){
           f=118;
         };     
       }

       if(mod==1) {
    f=f-0.05;
         if (108>f){
           f=108;
         };     
       };

       setprop("/instrumentation/nav[1]/frequencies/selected-mhz",f);

      </script>
     </binding>
   </key>
</PropertyList>


With F1/Ctrl+F1 You can change frequency in 1 MHz step, with F2/Ctrl+F2 with 0.05 MHz step. Copy and paste this code to file for example kbdrdctrl.xml, load this .nas file from airplane-set.xml file with syntax :

Code: Select all

 <input>
  <keyboard include="kbdrdctrl.xml">
  </keyboard>
 </input>

Adding long scripts is beyond me. I am afraid I will break something. I was think more of assignable 'Custom' keys for Calibration tool or the short codes that go into FG settings. Thanks anyway

If You save that code into standalone file, there is zero risk of break something.

Indeed. I think these FlightGear wiki articles might be of help:

• FlightGear configuration via XML#Adding your own settings (permalink)
• Howto:Reassign keyboard bindings (permalink) (And adding the new key bindings to your own preferences file.)
