The knock detector was a fairly straightforward problem to solve with some degree of accuracy. We first measured the x, y, and z readings from the accelerometer, waited a fraction of a second, and then measured them again. At this point, if there was any difference greater than or equal to 4 in the two x, y or z readings, we determined that there was sufficient change to have detected a knock. Because we are testing for only the delta of the measurements, the board can be in any initial position and still detect knocks.
