Erratic IMU in APM 2
Started this discussion. Last reply by Nicholas J Anderson May 4, 2012. 3 Replies 0 Likes
Hello,I'm attempting to solve an issue with IMU readings from a new APM2 being used on a multirotor (hex).Artificial horizon 'jumping', constantly changing orientation, rapid random steps-not…Continue

Nicholas J Anderson replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"I think I keep bouncing around terms incorrectly. I want to read where the gimbal is pointing, not traveling. So that I can point it due north, east, etc.
Any advice as to why this incorrect values are being stored in "yaw".…"
Nicholas J Anderson replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"I'm trying to grab the actual heading of the gimbal so that I can hold a desired heading, which can be the heading to face GPS coordinate. I'm getting accurate, pitch & roll, lat, long, and gps altitude values, but I'm not…"
Nicholas J Anderson replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"Oh and yes it is a continuous servo for the the yaw. I know there must be something simple I'm getting wrong for the incorrect heading readings. I think it might have to do with the angle of the APM2 or me not initializing the…"
Nicholas J Anderson replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"Yes the gimbal is to be attached to a multirotor. Down the road: have a couple APM1s that I was going to attach to the subject (moving or stationary), and feed lat/long and alt to the Gimbal APM2.
I've implemented PIDs that work…"
Michael Pursifull replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"If I remember correctly, there is heading and there is bearing. One is the direction the airframe is pointed, and one is the direction it needs to point in order to get to a place (which, depending on wind and other factors, may or may not be the…"
Michael Pursifull replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"Have you considered looking at the code for the ArduPlane instead? The reason I ask is if all you want is a static heading direction, that is easy enough. However, as your gimbal moves through space, the heading to your point of interest is likely…"
Heidi Goeringer replied to Nicholas J Anderson's discussion Getting Reliable Attitude & Heading Data in the group Learning to program the Ardupilot Mega"Pretty awesome! I'm interested to know how to read the heading as well.

Getting Reliable Attitude & Heading Data
Hello,For the sake of better understanding APM guts I've been working on what I've been calling ArduGimbal. I've just assembled code together looking at Arducopter 2.5.5 for how to structure the code and Arduino AHRS example & Compass example code to get heading and attitude. I'm using an APM2.I've made a triple axis gimbal out of a Hobbyking gimbal, a prop balancer and the main rotor gear from a 450 sized heli.…See More
Nicholas J Anderson replied to Daniel Nugent's discussion Custom code on APM 2.0 in the group Learning to program the Ardupilot Mega"It's not too complicated to 'assemble' the code from scratch though. Using the existing libraries to get attitude, position, and user readings and then using that to manipulated servos outputs and what not is not too hard and a…"
Nicholas J Anderson replied to Nicholas J Anderson's discussion ArduGimbal in the group Learning to program the Ardupilot Mega"Alright you have to enable each channel you want to use, I'm guessing this is where Arming motors comes into play for Arducopter.

Nicholas J Anderson replied to Nicholas J Anderson's discussion ArduGimbal in the group Learning to program the Ardupilot Mega"From looking at examples, it seems that this is the class that deals with writing PWMs to the output channels but I can't get it to work. Is there a description of what each method is meant to do somewhere?
class…"
