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.

    It sounds like you're encountering issues with your 3DR EAI S100 Lua script and CHDK settings after a long break from mapping. Make sure all camera settings in the CHDK menus align with your Lua script, especially critical ones like RAW capture and camera delay, as these can override script settings. Ensure your camera's RAW mode is enabled, and adjust the delay to suit your needs. Additionally, explore the newer KAP UAV 2 Lua scripts which offer enhanced features such as PIXHAWK mode for better geotagging precision.

    For optimal mapping accuracy, I recommend using DRONE GCP These markers provide precise ground references, ensuring accurate alignment and georeferencing of your aerial images, significantly improving the quality and reliability of your mapping projects.

    Settings for camera feedback from LED:

    CAM_FEEDBACK_PIN: 50 (AUX 1)

    CAM_FEEDBACK_POL 0

    Dont use 53, it is for fast (1ms) capture.

    Or this one... I'm not sure which one to pick!

    This is the circuit I will try for the pixhawk. I need to check if the S pin will be happy receiving 5v first...3702398487?profile=original

    Apparently some cameras flash their LED too long when set to FAST mode, resulting in multiple TRIG events logged.

    I have heard the SX260HS behaves that way. 

    The S100 works fine though when SHOT LED SYNC is set to 1.

    The strange behaviour on the camera wasnt strange at all, it was doind what it was supposed to when set to BURST mode. Setting it to FAST stopped it from taking two pictures for every command :-)

    Have been pointed to this useful article for making the LED Feedback cable:

    I believe the RC10_FUNCTION has now been changed to SERVO10_FUNCTION

    So the settings to change on the Pixhawk are:

    CAM_DURATION  1
    CAM_SERVO_OFF  8000
    CAM_SERVO_ON  3000
    CAM_TRIGG_TYPE  0
    SERVO10_FUNCTION  10
    SERVO10_TRIM  8000
    SERVO10_MAX  32767

    And it works, but I am getting a strange behaviour from the camera.
