Hello dear mapping community,
since this is my first post - a little about me and my project using CHDK/KAP script:
I am working in the agricultural world and I am doing some NDVI analysis and some Mapping in RGB only wavelength.
My platforms are a quadrocopter and a hexacopter running arducopter (Pixhawk). For regular mapping I use a Canon S100 connected with a DIY shutter cable build from this manual (it works great)
http://ardupilot.org/copter/docs/common-apm-to-chdk-camera-link-tutorial.html (I am using the setting USB shot controll=2)
So triggering from the pixhawk every 5-10 seconds work, but I want to fly a mission with triggering directly from the script to generate more pictures (everything the S100 could achieve), so here are my questions:
1) I tried the "turn display off" setting but it dos not work. When I have the script triggered from USB or when I have the script on "every 10 seconds", after the first picture the display stays off, but the second picture will turn the display on again and it stays like this. Can this be fixed somehow?
2)Since I want to use the script to trigger a picture after 5-10 seconds I want to geotag the pictures using a photodiode as mentioned in the posts before. I tried some settings and the shot-sync-led: 10 will make the front led to light up 3 seconds after every shot.
Is there any manual how to build a cable for the pixhawk's digital input using a photodiode - I could not find anything?
BR,
Lorenz
