Module/Servo switch
This module allows you to easily control a servo output like a switch (e.g. for a hatch, cam trigger, etc) via Flight Plan and GCS (not via RC!).
To use it load the servo_switch module:
| File: conf/airframes/myplane.xml |
<modules>
...
<load name="servo_switch.xml"/>
</modules>
|
Now you only have to declare a servo in your airframe.xml that you want to use.
By default the servo_switch module looks for a servo called SWITCH. The switch on value is 2000us and switch off is 1000us by default. e.g. in my airframe file I have:
| File: conf/airframes/myplane.xml |
<servos>
....
<servo name="SWITCH" no="7" min="1000" neutral="1500" max="2000"/>
</servos>
|
If you want to use a different servo/values you can set that in the modules section, e.g. for a servo named HATCH:
| File: conf/airframes/myplane.xml |
<modules>
<load name="servo_switch.xml">
<define name="SERVO_SWITCH_ON_VALUE" value="1100"/>
<define name="SERVO_SWITCH_OFF_VALUE" value="1900"/>
<define name="SERVO_SWITCH_SERVO" value="HATCH"/>
</load>
</modules>
|
Of course you only have to set these parameters here If you do not want to use the DEFAULT servo (SWITCH) or the default on/off values. Switch value will not go outside the range defined on the servo
Calling from Flight Plan
In your flight plan you just call the macro defined in servo_switch.h
<call fun="ServoSwitchOn()"/>
or
<call fun="ServoSwitchOff()"/>
respectively.
Buttons in the GCS
To get buttons for the servo switch module in the GCS add conf/settings/modules/servo_switch.xml to the settings files of your aircraft.
