Hello,
yesterday i tested the filter (V3) and CPU-usage of  PI-Zero goes really down.
Only one problem existed: sometimes i got nothing usefull at the output of the filter.
So i took my scope connected to input and output of the filter:
over minutes the output was inverted to the input, that's not good.
So i changed the toggle in PCINT0-ISR into reading REC_OUT and writing this to PI_IN.
Now the inverted pulses are away.

What do you think about it?
