I'm computing a first order estimate of the present AoA value based on the x preceding values, this is scientifically more accurate than a simple average and doesn't overload the cpu... Presently my setup is based on 10 values which makes the indicator quite reactive, but it is quite easy to program the software to have this adjustable.

Sounds great, not sure if it would work better to filter the raw sensor values or the computed AOA.

Also maybe could get by with an IIR running in Int32's.

Xavg += (Newsamp - Xavg) k; // maybe k=3 for short up to k=8 for long

Looking forward to having h/w. Starting to think about how to add the new ports with the nose release.
