Re: [Paparazzi-devel] Fast motor switch off

[Andrius Batalauskas]

Hello Mr. Warmers,

I don´t know about that kill switch but maybe a faster disarming procedure will do the trick. Passage from our documentation-in-progress (German though):

"Die Verzögerung des Motorenstartes wird bis einschließlich der stabilen Version 4.2 der Paparazzi Software in der Datei autopilot_arming_yaw.h eingestellt. Die Variable MOTOR_ARMING_DELAY gibt die Anzahl der RC Signale an, die nacheinander die für den Start bzw. das Abschalten notwendige Position des Yaw-Hebels senden müssen. In der Standardkonfiguration sind dies 40 Signale.

#ifndef MOTOR_ARMING_DELAY

#define MOTOR_ARMING_DELAY 40

#endif

 

Dieser Wert ergibt bei einem 35MHz Sender eine Verzögerung von etwa einer Sekunde."

You should also be able to define that in your airframe file:

<define name="MOTOR_ARMING_DELAY" value="20"/>

Hope, it helps!
Andrius

PS:  Just ask Mr. Frommann, if you are interested in the rest of our documentation. Should be finished by Fr.

Hi Eduardo,
how can i  config it?
The switch on the ground station is not possible to use, the switch  for mode by a switch  on the rc transmitter acts to late.
