I’m experiencing 0 output on navio+ pins, my qbrain 4x25a esc says throttle signal is abnormal (also when the quadcopter is armed and throttle is high/low). Although with my servo tester the esc and motors work fine.
I’ve also tried with a LED, which doesn’t glow at all on whatever pin or polarity i put it on. I’ve tested with both mission planner and the servo example from the docs. Although the LED glows with my servo tester.
I’ve tried the same thing with a voltage measurer and got equal results.
i’m using the newest version of emlids navio+ os, Mission Planner 1.3.50 and APM:Copter V3.4.6
Here’s a picture of my setup:
I did this for all pins on the navio board and the lamp never lit up. Considering that the current only goes one way through an LED it’s alot of combinations!
The wierd thing about this is that it lit up with my servo tester, when put between + and signal pins.
If you want me to run anymore checks just tell me!
Excellent point, during my first two pictures (in this thread) i was connected to missionplanner.
Although in the following one i was not but the A and C LEDs are still glowing:
