Pretty neat Chris. You've very nearly recreated a special kind of optical encoder that was developed by my former employers called a virtual absolute encoder. It didn't use diferent colors but it used a "time-window" to read the last few states off (...) (24 years ago, 12-Apr-01, to lugnet.robotics)

(...) Can't you just use a large switch() statement inside a function to simulate a 64 element array? If none of the values in the array ever change: int array ( int x ) { switch ( x ) { case 0 : return element_0 ; case 1 : return element_1 ; case 2 (...) (24 years ago, 12-Apr-01, to lugnet.robotics)
