Talking about rolling average, I use a AIN block with filter option.
That just works a gem.
Anyone ever thought about 0-360deg wind vane damping?
See the problem around North? 1,360,1,360..... would average 180 wouldn't it?
Here is what I did.
In a CALC block split out the SIN and COS and output it to say RO02/03
Those two outputs each go to an AIN block with filter option ON and filtertime say 1.
The output of those AIN blocks is then fed back in the CALC block to be ASINed and
ACOSed and with a bit of smarts put back together to form 0-360deg.
There you have it. A very well stabilised wind vane signal which can now be used to
drive an directional indicator (FoxView) without driving the operator mad.
