HIL_ACT_FUNC parameter, What does it mean?

[takurx]

I would like to make custom HITL airframe file.
I referred to sample HITL airframe file (that is 1002_standard_vtol.hil, 1100_rc_quad_x_sih.hil, 1101_rc_plane_sih.hil).

What does “HIL_ACT_FUNC” parameter mean?
I couldn’t find it from parameter reference.

• Parameter Reference | PX4 User Guide (main)

  • Parameter Reference | PX4 User Guide (main)

• What number does “HIL_ACT_FUNC0” ~ “HIL_ACT_FUNCX” exist?

  • Does it seem that 10X is PWM?
  • Does it seem that 20X is control surface?
  • What is 400?
