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:
<modules>
...
<load name="servo_switch.xml"/>
</modules>
Now you only have to declare a servo in your airframe.xml that you want to use. Previously you had to set up commands, command laws as well.
Configuration
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:
<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:
<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="SERVO_HATCH"/> </load>
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.
Calling from Flight Plan
In your flight plan you just call the makro 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 settings_servo_switch.xml to the settings files of your aircraft.
