RESULTS -- Re: Averaging voltage reading from rectified DC (Differential Equation in perl)

OK, so, yesterday I tried to do what I wanted:

1) Have a RC filter with R=65 kOhm, C=0.47 uF. I read the
instantaneous value from this filter and use as a input to make
decisions when to turn high frequency arc starter on or off. I say, if
my measured bus voltage is more than 45 volts, turn it on, and if it
is less than 40 volts, turn it off.

This gives me a very quick reaction time (for me) average, with ripple
of about 2%.

2) For display purposes (I have a serial display), I take the value
above and further average it using exponential moving average. That's
so that display would not endlessly oscillate between similar
numbers.

It worked absolutely great. The HF relay engages right after I switch
voltage, with no lag like before.

I think that I will do the same with the current input, as well.

I also spent half the evening battling a seeming bug in the
microcontroller, where if I define a function taking a real number,
and call it, everything goes haywire.
