I simply don't know where to go from here - any wizards out there to help get this bird in the air - I thought I was at the point of beginning the PID adjustments for these new add-ons, but looks like I've missed the boat somewhere.
If I disconnect the add-ons from the FC and reload the previous sketch I get the sensor feed back and of course the I2C error is at zero.
Please enlighten my ignorance.
All the best, Don
