Why do you think you need both? After something is rising, it is high, so both seem not to make sense. > + mount-matrix = "-1", "0", "0", > + "0", "1", "0", > + "0", "0", "1"; hmm, checking twice, since I mixed up something earlier. This just inverts x values, so we are mirroring across y-z plane, that does not look like a rotation matrix, so it does not describe how it is mounted. Eg. the n900 has two -1 in there, that is a turn by 180 degree. Your mount-matrix would be achieved, by cutting the chip into ultra thin slices, sorting them upside down and glueing that together. I doubt somebody does that. Regards, Andreas
