It looks like this (I didn't study that code but took a brief look). But
that one has additional code to process data coming from serial port, which
makes it more difficult to decipher that tiny portion of algorithm itself.
Without looking into WIKI info, it is possible that, I wouldn't be able to
separate algorithm from other parts of code (unless I know, what algorithm
is).
