Hi Lauszus,

All sorted out now. I had everything coded correctly but missed the initial offset from zero for the down axis accelerometer due to gravity.

It works very well and rejects linear movements really well.

Just need to feed the angle into my motor controller now.

Thanks for everything!

Hi Lauszus,

I have your code running ok with the single gyro and x,y,z accelerometers.

I'll dump the intermediate angle calculation values out and see if I can figure which pair I need to combine with the gyro.

Cheers,

Richard.

Hi Lauszus,

I've been learning a lot from your code, thanks very much for putting it on here.

I have a board with single axis gyro with 3 axis accelerometer, analogue outputs.

I'm looking to find the Roll angle, so the single gyro board will need to be orientated up on its end so that the Roll axis goes through the middle of the gyro. The accelerometers with then be: X=up/down, Y=left/right, Z=forward/backward.

In this configuration which combination of the X,Y and Z accelerometers should I be using in the code?

I am guessing that it's the X and Y as the Z axis accelerometer is not effected by roll when the board is mounted on it's end

Your code uses X and Z and Y and Z in the arctan function, so I should use X and Y, correct?

Anyone tried adding a $5 wifi dongle to a USB host shield to get a low cost wifi solution?

Is it really cheaper to make a wifi interface for an Arduino from a Raspberry Pi and an Edimax usb wifi dongle???

Or for an even cheaper route, use an Edimax wifi router/repeater (less than £20) and stick OpenWrt on it???

Seems all wrong to me?

What is the score with an Xmega Arduino? I have found a few general purpose dev boards with xmega on but no sign of an arduino compatible one???
