I use the version 3.8 of arduplane
Since severals weeks i am block to control pin 17 or 18.
Before, i can trigger my canon dslr in this pin port with trigger on relay, pin 17 etc… in mission planner.
Now, i can’t trigger with this same configuration, i connect a led on the uart cable ground and yellow or green cable for pin17 and 18 and i see that the led is lightnning by 4.7v
is it normal?
if i need to trigger on pin 17 or 18, i will not have power when i don’t trigger it, no?
how can i test my pin port to see everything good with navio?
Thanks a lot for your help
