Hi there I bought a couple ArduPilot w/ ATMega328 boards a few years back, but didn't get to use them .... work got in the way! I'm still keen to do something with them -- using an IMU set-up - but…Continue

I don't know why I still fool with this but I do. I'm running FreeIMU, outputting DIYd binary on a Flip1.5 instead of the ArduIMU. I added a I2C daughter board that sends the Ublox protocol to the Flip. It took me a while to figure out the binary enough to get the ArduIMU Test to read it. If that program will read it, then the Ardupilot will.

The only benefit is a $15.00 IMU, $5.00 I2C daughter board vs. $75.00 ArduIMU. That would bring the combination IMU/Autopilot to about $60.00 with GPS. The other benefit is I get to learn a few things.

It'd be nice to squeeze all the Ardupilot stuff onto the $15.00 Flip. That would take some rework and combining with Multiwii code. The Ardupilot does a good job of handling modes and navigation, but the multiwii does a good job of combining IMU with reading radio. Somewhere in there is a decent little autopilot.

its a MPU6050 6-axis gyro/accel sensor attached to a piggybacked brushless motor driver pcb on an arduino pro mini 328p

Just a shrunk down brushless gimbal controller

still deciding what version of the firmware is best

6050?  I see an ArduSomethin attached to an I2C IMU. 

I made progress and added GPS to Martin's code and I've got it sending GPS and attitude to the Ardupilot in binary.  Ardupilot even shows a solid blue light now and is smoother with GPS added.

been working with the 6050 chip on my gimbal controller project

ahh I have the IMUv2 Flat :(

Martin Crown deserves a huge thanks for publishing his code. 

Some of the stuff I was trying might work with his code.

Nice I'll look into that!

I've flown my Legacy and IMU once this summer.  There's a thread about using DMP on the IMU which has me playing with it again.  I managed to get the IMU talking to the Ardupilot and stabilizing using the awesome DMP.  I also have it outputting to the ArduIMU Test program @38400 nicely.  The DMP reduces the program size to about 1/2 the original size.

Me too.

I made another use profile, I found everything installed much better on it and runs smoother too
