sb - se, sc - sf

[FlyingEagle]

Which one of the variables above is the right for the real wind-speed and the real wind-direction?

[bunnyhu]

sprintf(a, "Wind direction: %d\t%d\n", sb, se);
sprintf(a, "Wind speed: %d\t%d\n", sc, sf);

Both is real :) You can dig the code in my weather station, also here in github.
