[Paparazzi-devel] What's wrong with throttle control?

[Steven Wawryk]

Hi,

I'm trying to get a flight plan to partially spool up the throttle before launch 
but I can't seem to get the pre-launch throttle to any values other than 0% or 100%.

When I set it to 0, the GCS reports 0%, when I set it to *any* non-zero value, 
the GCS shows it slewing up to 100%.  It only seems to be boolean until a 
control loop sets it after launch.  This happens for both sim and ap targets. 
With ap, the throttle servo confirms it.

I've tried it using <attitude roll="0.0" throttle="0.5" vmode="throttle" 
until="suds_cld_launch_detected"/>, with other vmodes and by setting each of 
v_ctl_throttle_setpoint and ap_state->commands[COMMAND_THROTTLE] to MAX_PPRZ/2, 
but all give the same result.
