Using Sketch " 1/4/2013 original by Jeff Rowberg <jeff@rowberg.net> at https://github.com/jrowberg/i2cdevlib"
requires both classes must be in the include path of your project
#include "I2Cdev.h"
#include "MPU9150.h"
#include "helper_3dmath.h"
found/downloaded I2Cdev; however, can't find the other two ..9150.h or helper...
Very frustrating for me due to my TBI/PTSD. Hoping to make play display similar to a glass cockpit display. Have several grandchildren excited about learning electronics and programming. With interest pointed toward useful interaction, they are staying away malicious code hacking desires.
Jeff's original sketch sparked my interest; however, frustration with Arduino documentation being sketchy and/or lacking sours desire. Had seen an Italian Arduino glass cockpit like display some time ago but unable to find it again. Ah yes, good old TBI strikes again.
I welcome direct contact at "glavra@yahoo.com".
