Triggering the Camera with Pixhawk by CHDK??

Hi..

I want to  trigger my camera with Pixhawk by CHDK such as these links:

This method doesn't need any circuit, just connecting red cable from USB to (+) pin and black cable to Signal pin in AUX port.

So, I try to make a cable myself such as attach files. Is that right?

And the setting of MP is 

  • CAM_DURATION: 1
  • CAM_TRIGG_DIST: 3
  • CAM_TRIGG_TYPE: 1
  • RELAY_PIN: 54

And the connection of Pixhawk and my canon S100 also like attach files.

actually, I am not sure whether the connection is right or not...

The script of CHDK I use is E38_APM.bas.

BUT!!

The camera still cannot work!!

Is there something wrong with CHDK or MP setting?

 

THX!!
