Mkblctrl driver not working with Pixhawk and Arducopter 3.2


We are trying to make arducopter 3.2 work with our mkblctrl v2.0 motor controllers from Mikrokopter. We followed this guide … opter-with and did exactly the same, but all that we see is a red light on the main LED from the pixhawk and when connected to the motors they all just spin up to some value and hold it there. We have no control over it with the transmitter, everything has been calibrated in mission planner.

Has anybody had a similar problem? Any help would be appreciated.

Oh, yes. I have exactly the same problem. I didn’t notice your post before. I wrote a similar post here. Have you had any luck figuring it out? I don’t know what to try next, other than to connect an I2C bus analyzer, which is a bit of a pain.

Were you guys able to figure out what the problem is?

I’ve just solved a problem like this bu removing a serial resister on I2C SDA line. So I guest the problem is caused by I2C communication error.
