PIXHAWK FW3.5.2 + Canon S100 CHDK Mapping Troubleshooting UPDATED

After a failed attempt to do some mapping which resulted in most of the pictures NOT being taken, and the ones that were taken being very blurry, I went through my 3DR EAI S100 Lua script and found a lot of the settings had been changed. It has probably been a year since I tried to do any mapping and was disappointed that it didn't work like last time.

Having been through all the settings for the camera and the script that I could find here:

https://github.com/ArduPilot/ardupilot/tree/master/Tools/CHDK-Scripts/Cannon%20S100

I am left to wonder about the other settings in the CHDK menu's...

Do they also need to be adjusted? For example, I found that RAW had been disabled, and that Camera Delay was set to 2 seconds... Do they override the LUA script settings?

Are there are any other settings in there I should look out for? The menu's are quite comprehensive and exhausting to go through. I have been through them all but it would be great if the mapping pro's out there could give me any other tips on what to look out for...

For the record I am using a 3DR Quad 2014, Stock (Just ordered a new GPS Here) with Pixhawk, 3DR Radio Telemetry, Multistar 10000mAh 10C Battery, Custom Camera Control USB cable, Canon S100 mounted using a Gopro Mount with Camera thread adapter, Taranis X9D with Flight Deck and a FrSky Lipo Voltage Sensor.

UPDATE: Have just discovered the newer versions of KAP UAV 2 Lua scripts... Mind Blown ha ha ha

Am very excited to learn about the new PIXHAWK mode and that I can now get feedback from the camera when its shutter is opened giving greater geo tagging precision!

The next trick is to get the new PIXHAWK mode working and make that LED sensing cable - Anybody have further information on this circuit?

I don't want to buy the Tuffwing cable for $40.

This is the post I made in the CHDK forum asking for more information - especially regarding to RC10_FUNCTION. Any help you can offer would be much appreciated!

Hi Everyone, Thankyou waterwingz for the time you spend making this awesome script better and better!
I have a Pixhawk FW APM:Copter V3.5.2 and S100 running CHDK 1.3.0-4228 S100-100e with KAP UAV 3.8 Beta script. My RC is a FrSky Taranis X9D with X8R receiver running latest firmware, OpenTX and FlightDeck.

My setup works successfully when I set it up the "old fashioned way" using my DIY cable to trigger S100 from Pixhawk via USB.
I have been reading up here and in the SH260 forum (https://chdk.setepontos.com/index.php?topic=13028.0) and on the tuffwing page (http://tuffwing.com/support/pixhawk_camera_trigger_cable.html) about the option in the script to trigger via USB called "PIXHAWK" which gives greater accuracy in the logs for GPS positioning when mapping. I am also interested in the LED feedback for even more precise GPS tagging.
I would like to use these methods, but for now, I don't have a design to build for the feedback cable, and I am currently unable to get the "PIXHAWK" USB Mode working.
So first things first, I need to get the trigger side working.

The following is from the Tuffwing page, listing the parameters to adjust in Mission Planner's Full Parameter List:
CAM_DURATION 1
CAM_SERVO_OFF 8000
CAM_SERVO_ON 3000
CAM_TRIGG_TYPE 0
RC10_FUNCTION 10
RC10_TRIM 8000
RC10_MAX 32767
I can find and adjust all of the parameters except for the RC10_FUNCTION parameter. It just does not exist in the parameters list. I have searched for RC, FUNCTION, even OPT for option. Is this an APM:Plane only setting? Is there a way to use this in Copter?
As a side note I have CH10_OPT set to 9 (Camera Trigger).
I also read in this forum waterwingz gave advice saying that the script is looking for a precise PWM pulse 3mS long, but the CAM_DURATION Parameters are set in 10ths of a second (i.e 1 = 10mS) and trying to input .3 results in a 0... So a pulse 0 seconds long is sent when triggered! That obviously doesn't work lol.

What am I missing?

Hi All; I'm new to this forum and this is my first post: thanks to all developers and contributors for such an awesome work!

Hi Stanley, thanks for your response.

I have no desire to use the Stock Canon firmware when I know the CHDK achieves better results.

Sandy Sound Helo, use this setting;

Camera mode : TV Shutter speed priority

Then go to Func. Set. to set the following.

ISO : Auto

Cloudy
4:3

JPEG only

FlexiZones

Am wondering if this Photoresistor is suitable for the LED Feedback cable?

I have had trouble implementing the new "PIXHAWK" USB trigger mode in the KAP UAV 2 lua script.

These forum posts have been very useful for me in understanding the setup:

https://chdk.setepontos.com/index.php?topic=10822.950

https://chdk.setepontos.com/index.php?topic=13028.0

And the Tuffwing pages:

http://tuffwing.com/support/pixhawk_camera_trigger_cable.html

http://tuffwing.com/support/Install_a_canon_precision_geotag_cable....

Otherwise there seems to be very little info out there. If anybody has any experience getting this working with the latest APM:Copter FW your help would be greatly appreciated!

This is the best? circuit diagram I have found so far to build for the LED feedback cable:

What do you think?
