Hello

I build a servo gimbal for my tricopter but I can't make it work. I did this in arduino:

/*********************** Cam Stabilisation ***********************/
/* The following lines apply only for a pitch/roll tilt stabilization system. Uncomment the first or second line to activate it */
//#define SERVO_MIX_TILT
#define SERVO_TILT

/* camera trigger function : activated via Rc Options in the GUI, servo output=A2 on promini */
// trigger interval can be changed via (*GUI*) or via AUX channel
//#define CAMTRIG
#define CAM_TIME_HIGH 1000 // the duration of HIGH state servo expressed in ms

When I open the gui the flight mode "cam stab" is there but when enable nothing happen. I connected the roll and pitch servos as in this picsture:



My board it's a crius se v2.5. I read that all adjustments related to gimbals now have to be on the GUI but I dont see there options for that.

This is the gimbal that I build:



What am I doing wrong or is missing to make this gimbal work?

Thanks,

Any ideas?
Thanks

Hello gonçalo,

Nice gimbal! Did you find a solution for your Problem? I have a similar Problem with the MWC Mega 3.0- board (http://www.goodluckbuy.com/mwc-mega-...-version-.html). I want to use a gimbal with two servos and MWC 2.3. The servos don’t move.

Gimbal is setup from ServoTab in Gui.
Check this thread.

Is there 5 Volts on the centre pin ????
not all boards provide the 5V on pins 43-45 (for Mega, not sure for promini)

Hi wilco,

You are right, there is no voltage on the pin. I took the voltage from another pin. Now everything works fine.

Thanks,

Alright, glad to know that solved it....

BTW, if your looking into controlling the camera pitch from your remote, you could modify the MW code slightly...

change: (in output.cpp)

#if defined(SERVO_TILT)
servo[0] = get_middle(0);

Into

#if defined(SERVO_TILT)
servo[0] = get_middle(0) - rcData[AUX4] + 1500;

That will allow the pitch to be controlled by AUX4. You might want to play with the + / - to get the direction you want...

Or select channel in Gui Direct.
Just pull The upper slider fully to the left to get RC channels.
Fully Right to go back to Centerpoint.
