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?
