After a couple of tries here my results.
Still 2 problems, but at least the hat works.
Problem 1) Only 7 of 8 direction works as for some reason the physical
maximum value doesn't work (the correct value must be 240-30=210 equal
to direction 7) so i put as logical maximum 14 and not the use 8 2) to
correct the opposite direction of hat report count = 2 (??)
