Problem with assigning brakes via the external interface

Recommended Posts

While trying to assign the main wheel brakes to my pedals via the external interface I came across the following problem. 

I used the following lines to assign the brakes to my hardware pedals. 

J0_Y=FlightControls_->sensors.BrakeL0_ADC

J0_X=FlightControls_->sensors.BrakeR0_ADC

This at first seems to work and I can see my brake movement on the flight control page of the control panel. I can also assign minimum values for the brakes so they only get activated past a certain application level. For instance using the value of 1000 or 2000, since the max value is around 65500. Now, when I'm in the sim and try to taxi by applying power the plane is stuck to the ground (yes the parking brake is off of course and I am able to disengage it by stepping on the brakes real quick). The weird thing is, that when I slightly apply some brakes the planes actually starts rolling, when I let go again the brakes seem to grip again, which isn't represented in th control panel. Am I missing something here? 

Also, when I assign the brakes via P3D they work just fine. Only not via the external interface. 


 

With kind regards, Bogdan Misko.

Bogdan,

It could be a simple fact that the brake axis need to be inverted. 

"-"  the use of a minus sign, tells the connector that an axis or a button press must be inversed.  The Special Features document provided with the MJC Q400 PRO speaks of its use.

Give this syntax a try instead:

J0_Y=-FlightControls_->sensors.BrakeL0_ADC

J0_X=-FlightControls_->sensors.BrakeR0_ADC

Thanks, this works perfectly! No idea why the CP was showing a correct logic with a wrong assignment though. 


 

With kind regards, Bogdan Misko.
