This example contains all possible configuration options, not all of them are mandatory!

<modules>
  <load name="servo_switch.xml">
    <define name="SERVO_SWITCH_ON_VALUE" value="pwm" />
    <define name="SERVO_SWITCH_OFF_VALUE" value="pwm" />
    <define name="SERVO_SWITCH_SERVO" value="nb" />
  </load>
</modules>

Module configuration options

Define Options

• name: SERVO_SWITCH_ON_VALUE value: pwm
  Description: servo value in usec
• name: SERVO_SWITCH_OFF_VALUE value: pwm
  Description: servo value in usec
• name: SERVO_SWITCH_SERVO value: nb
  Description: Id of the servo (default: SWITCH)

Module functions

Init Functions

These initialization functions are called once on startup.

• servo_switch_init()

Periodic Functions
