Sorry about the amount of space that just took

Should have used the Code tags and not the Quote tags (it also keeps the formatting correct).

rgr, my bad, must have 'miss clicked'

gramo, if you take eight samples and just shift left three times
is faster than dividing by a decimal number

or take four samples and shift left two times

you get the idea.

I think 20 readings and outputs/sec would be fast enough, and I think with a 4M clock and prescaler set to 256 it should be plenty fast enough. (I've guesstimated, I'm still not to deep into the math of pics.)

Speed is rarely a problem, PIC's really run extremely quickly, and your project is only a very low speed one.

Thanks. I would rather use an IC just for saving space.

Just on a side note does anyone know of a through hole to surface mount adapter?
