Hi

I posted earlier about getting the script to work and I managed to get it to work with the SimpleShutter cable from http://www.mobilexcopter.com. I managed to trigger the camera using my pc version of mission planner and my RC (chan7).

I tried to use 3DR Tower software to use the structure scanner to fly over an area and automatically take pictures. As S90 is not available in the Tower software I chose S100 but it does not seem to take any pictures. CHDK is running and the KAP_UAV Script is running as well.

Does anybody have experience with 3DR Tower software on android , CHDK , and the KAP_UAV scripts ?
Do I need the script ?

Please copy the KAP.LOG file from the root folder of your SD card and attach it to a post here.

It's possible to trigger shots with just the CHDK USB Remote settings. But it all depends on how you have your flight controller software configured.

Hi

I actually wanna trigger the camera via the 3DR Tower Software on my android tablet but as there is no S90 to choose, I chose S100 in there. I am not even 100% sure this is the right place but I am a bit unsure how to debug that.

Here is my KAP.log for today:

I took a very quick look at the 3DR Tower git repository but it was not clear what the camera setting is supposed to do. Certainly the code has no way to know if you have an S90 or S100 attached.

Here is my KAP.log for today:

From your log file, it does not look like your system is toggling the USB line to the camera at all. So this does not appear to have anything to do with CHDK or the kap_uav.lua script.

I notice you've posted this issue over on the ardupilot forum (and possibly elsewhere?). That's probably a better place to get an answer.

Hi

I am still debugging my S90 / Tower app issue. According to the maker of my shutter cable, the pulse sent to the chdk script is hat the pixhawk outputs (like it mirrors it).
How long should a pulse be at least for the OneShot Mode ?

What does this log tell me ? (It shot 1 picture at the beginning but that's all)

This one ? Simple Canon shutter - Pixhawk version

It should catch anything longer that a couple of milliseconds.

Basically, it tells you what you just said - i.e. it shot 1 picture at the beginning but that's all.

However, the "shoot full" timeout message is interesting. It looks like there was almost no light - where you shooting in a dark room?

Hi

Yeah I am using the cable you mentioned.
Right now the pulse is around 1/10 sec long and the cam should shoot as fast as possible. You are indeed correct, the light was not the best here, yet it was not dark but now I know what this error message means.

I am still wondering if it's some issue of the Tower App or the pulse sent or the App doesn't correctly send the commands to trigger but the people there are a bit unresponsive so maybe I need to dive into the app code ...

At this point, I don't think it the kap_uav.lua script, or how you have set it up, that is causing the problem. So I've attached a simple script that measure the width of each USB pulse and prints the result to the camera LCD. It also reports the time between pulses. You might want to use it to test if pulses are being generated (and how long they are) while you work on your flight controller setup. Should be accurate down to about 1 mSec resolution.

You can ensure the USB test script is working by using a standard USB cable between your camera & PC. Just plug & unplug the cable a few times while the script is running and your should see timing values scroll up the screen.
