znalazlem cos takiego:

he code for Nikon cameras:

Frequency = 40kHz
Each bit is 500uS

Start bit = 1.885mS
first break = 27.3mS
Bit 1
Second break = 1.5mS
Bit 2
Third break = 3.5mS
Bit 3

Total 3 bits with one start bit

kinda look like this:
--~______~--------~_~----~_~--~_~--------



czyli wlaczenia diody:
on 1.885ms
off 27.3ms
on 0.5ms
off 1.5ms
on 0.5ms
off 3.5ms
on 0.5ms
