Problems with Pixhawk I2C External LED

Posted by ausdroid on August 19, 2014 at 6:10pm

Hi,

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?

Thanks

Found the problem. Faulty I2C splitter.

  It's been a long time since you posted this...
  
  How did you find out it was a faulty i2c splitter?
  
  I have exactly the same problem with a brand new splitter.

    I think this is not a i2c splitter issue itself but i2c inteferance. There was a same article on it. http://diydrones.com/forum/topics/i2c-splitter-problem?page=1&c...
