counter(avg)
koadrobot/logic/counter(avg)
Stores a number which gets incremented on each `INC` pulse.
AVG=SUM/IDX
When RST pulse, SUM reset to zero.
If STEP is neagtive then Decrease.
Dont Set outputs differ from zero.

Dont Set outputs differ from zero.
STEPnumber
Value to add on each increment. Use a negative value (e.g. -1) to make decrements.
INCpulse
Triggers a single step.
RSTpulse
Resets the counting value to start.
AVGnumber
The average value.
IDXnumber
The counting index value.
