If anyone is interested I have successfully learnt the math that computes a direction Cosine Matrix from the raw accelerometer and magnetometer readings from the phidget spatial. I just need to implement the gyroscope into this then decide how best to output my data but happy to share my patch if an...

Does anyone have any experience with the 3rd part madgwick filter by Roger Isaacs in LabVIEW? it takes accel 3 axis output in g/s, gyro 3 axis deg/s and magnetometer G/s and converts to Quat or Euler angles. I can't work out how to alter it into to take my phidget outputs? I can't attach the Madgwic...

Hi, can I ask regarding the magnetometer aspect of the phidget spatial. I read regarding the calibration software. I have two phidgets connected via a VINT. it defaults to one so I sequentially connected them and ran the calibration software. following the instructions. I'm using MAX/MSP for my prog...

Hi there, Does anyone have any coding that can output the spatial values as quaternions? I have used trigonometry to produce pitch and roll and complimentary filter to produce pitch and roll. For my next research however I need 3 axis and the pitch of the device is closer to 90 so it makes roll from...

Do you think it would work with the jit.axisquat obj? If I plug gyro data into it with an expr $f1*timestamp to create a degree rotation? That obj is supposed to convert 3axis rotation into a quaternion? My numbers at present work completely fine accept if I rotate the pitch >60degrees then try to r...

What I don't understand with quaternions is what value do I take from the raw gyro for the angles for quaternions? I've read lots of forums etc about it. I have the atan2 formula for the accelerometer calculation - but I use this as my correction for they gyro when its not moving. I can't work out r...

not sure if this is a good way have incorporated a way of calibrating the gyros using switches and bangs then automatically feed this result back to my gyros. I have the complimentary filter in place but was still getting significant drift from the gyro - mainly from pitch it never returned to 0 wou...

Smokes - fixed this

had space between words

should read - setDataInterval 20

it is phenomenal now the number speed

here is my screenshot
