; copy of AD_Newvalue, used locally
; previous value of filtering ( NewFilter from last run )
; the new filtered value
; how much weight that should be posed on old value
; to increase step response
; how often we want an global update
; the global update location
; get lowest byte
; add to filter sum lowest byte
; get next byte
;
; increase source
; and add to dest.
; get next byte
; get msb

; 32 samples between global updates
; filterweight, i.e. 'A' in example above
