Checks that the encoding described in in the following link is resilient to rotations. https://github.com/polyvision/EasyRaceLapTimer/blob/master/docs/ir_pulses.md

	def encode(n):
	if (n > 63) \| (n < 0):
	raise Exception('Out of range {0}'.format(n))
	ret = bin(n)[2:] # [2:] to chop off the "0b" part # creating initial bit encoding (for bits 3-8)
	ret += reduce(lambda a,b: '1' if (a != b) else '0', ret) # adding checksum as bit 9
	pad = ''.join(['0'] * (9 - len(ret)))
	return pad + ret # padding with leading zeros by spec (for bits 1-2 and maybe more for lower ids)
