Problems with Pixhawk I2C External LED



Pixhawk running Arducopter 3.1.5


What can I say? Plugged the external LED in to the I2C splitter and no pretty lights. I have the splitter plugged into the I2C socket on the Pixhawk and the external compass is also plugged into it. The compass is working but the LED is not.


There does not appear to be anything I need to do to enable the external LED. Does anyone know if it has actually been written into the code?

      How did you find out it was a faulty i2c splitter?

      I have exactly the same problem with a brand new splitter.
