Andrew Tridgell	fb90d16092	Filter: make the DerivativeFilter test GNUPlot friendly ... makes testing easier	2012-08-08 12:07:36 +10:00
Andrew Tridgell	2de06df08d	Filter: automatically cope with duplicate timestamps ... this makes it easier for callers to avoid excessive slope calculations Thanks to Jon Challinger for the idea	2012-08-08 12:07:35 +10:00
Andrew Tridgell	c9a56e2223	Filter: fixed a off-by-one DerivativeFilter bug ... many thanks to Jon Challinger for noticing this!	2012-08-08 12:07:35 +10:00
Andrew Tridgell	43d6015811	Filter: split the DerivativeFilter steps into update() and slope() ... this allows us to apply new data at a different rate than we calculate the slope.	2012-07-06 15:11:30 +10:00
Andrew Tridgell	9f3da1bf7f	Filter: fixed DerivativeFilter example build	2012-07-05 16:29:21 +10:00
Andrew Tridgell	92001e3e7d	Filter: fixed typo in 9 point DerivativeFilter	2012-07-05 16:29:20 +10:00
Andrew Tridgell	a07e280eda	Filter: cope with non-uniform time steps in the DerivativeFilter ... this helps with the barometer a lot, as the timing is quite variable	2012-07-05 13:00:47 +10:00
Andrew Tridgell	f97289792b	Filter: added DerivativeFilter implementation ... this adds a DerivativeFilter implementation of up to 10 points	2012-07-05 13:00:46 +10:00
Andrew Tridgell	9fd3d15026	Filter: added 5 point average float filter	2012-06-27 16:01:50 +10:00
rmackay9	fd5e1c2f7b	Filter - added FilterWithBuffer typedefs for int32t and uint32 for ease of use	2012-03-28 22:02:52 +09:00
rmackay9	2324be7e68	Filter - added simple LowPassFilter (simple but it's possible to make errors with simple stuff too so might as well have one)	2012-03-25 16:15:25 +09:00
rmackay9	bdda74fd28	Filter - remove obsolete warning from comments re alloc/malloc dangers	2012-03-25 16:14:07 +09:00
rmackay9	5b89c65d9c	Filter - updated example sketch to use modified library	2012-02-28 21:01:35 +09:00
rmackay9	d17a015df1	Filter - added AverageFilter, removed SumFilter ... added FilterWithBuffer to allow removal of malloc/free without losing ability to pass around filter objects	2012-02-28 21:01:11 +09:00
rmackay9	747e045193	ModeFilter - corrected shadowed variable compiler warning for drop_high_sample	2012-02-26 17:57:28 +09:00
rmackay9	e01477a7a8	Filter - added AverageFilter - this will be used in place of SumFilter because it removes the possibility of overflows	2012-02-26 17:34:36 +09:00
rmackay9	b345529241	Filter - removed shadowing of variables in constructors for Filter, ModeFilter and SumFilter (sorry tridge!) ... increased maximum sample buffer size from 6 to 10	2012-02-26 17:17:46 +09:00
rmackay9	ae8fd43335	Filter - first version of filter library include ModeFilter	2012-02-26 15:34:05 +09:00
