### Description
Driver for simulated PWM outputs.
Driver/configurator for the virtual PWMSim port.
This virtual driver emulates PWM / servo outputs for setups where
the connected hardware does not provide enough or no PWM outputs.
Its only function is to take actuator_control uORB messages,
Its only function is to take `actuator_control` uORB messages,
mix them with any loaded mixer and output the result to the
actuator_output uORB topic. PWMSim can also be performed with normal
PWM outputs, a special flag prevents the outputs to be operated
during PWMSim mode. If PWMSim is not performed with a standalone FMU,
but in a real system, it is NOT recommended to use this virtual
driver. Use instead the normal FMU or IO driver.
`actuator_output` uORB topic.
It is used in SITL and HITL.
