I would use my Iphone accelerometer and gyro coupled with Arduino. For my project I need to provide data to arduino code about iphone accelerometer and gyro (roll, pitch, yaw) in the PWM 'format'. I have read some iOS documentation and from iOS core motion library seem I can access only rotation matrix, euler and quaternion representation of motion data. Do you can suggest me a solution to obtain PWM values?

Best,

Lucio

  • Do you have more information about the PWM format that you're talking about? – joerick Apr 30 '12 at 10:37
  • @joerick Unfortunately no, because I'm using third part library (on arduino) to read pwm signals as its input. – murgy Apr 30 '12 at 11:06
  • that sounds unlikely, [PWM](http://en.wikipedia.org/wiki/Pulse-width_modulation) is a way of representing an analog signal using a digital output. What's the library called, and does it have any documentation? – joerick Apr 30 '12 at 11:10
  • the library is aeroquad (http://code.google.com/p/aeroquad/downloads/list) – murgy Apr 30 '12 at 12:01
