Using OP CC3D ESC/Servo outputs for lights question
« on: March 23, 2016, 10:19:11 pm »
I have a FlySky i6 Tx with it's ia6 Rx and an OP CC3D.  I also have this light kit that I'm trying to set up:

The kit is actually very simple as it only requires connection to an available channel on an Rx, however, I only have 6 channels and all of them connect to the CC3D receiver input, so I don't have an available channel on my Rx.

I thought that maybe I could run the lights off of the CC3D ESC output - there are 6, and only 4 are used for the motors. In LibrePilot I made the following configurations, all under the Configuration tab:
  • I connected the lights to the 6th set of output pins in the CC3D - black, red, and white are in the correct positions
  • Under Vehicle / Custom tab, I enable Ch 6 and set the type to Accessory 0
  • Under Input I set Accessory0 to PWM on Channel 6. It has a min and neutral value of 1000 and a max of 2000 (I still do not know what these numbers actually represent, and have asked under General Discussion). When I toggle the switch on my remote, I can see it respond in GCS, so I know that part works.
  • Under the Output section, Accessory0 shows on #6, bank 4, with a min value of 1000 and max 500 (don't understand this) and it's set to Reversed

I don't know if this is the way to do it, but I figured I'd try.  Regardless, it doesn't work. Can anyone assist me with connecting these lights either in the above manner, or perhaps a better way?  Being a newb, and ignorant, I tried to measure the pins on the CC3D, where my lights were connected, and toggle the switch, and I saw no change in voltage, but I'm not even sure what to look for on the signal pin.  The voltage on black and red is 5 v.

Connecting my quad and flashing the CC3D with LibrePilot was a milestone after several attempts... making these lights work will be HUGE! 

Thanks for any assistance.

No need to edit the custom tab, thats the old way now.

Better use the mapping feature under the vehicle tab, craft still recognized as a Quadcopter.

You can use the same method as buzzer described here:

Output should be set with min=1000 and Max=2000, maybe neutral at 1500 if multiples modes ?
