Average Values and digital filter ...

This might work for you.

Averaging 16 bit values without using 32 bit math?

Just wanted to say thanks to Darrel, I used this averaging routine in one of my projects that was driving me crazy and it solved the problem I had.

THANKS!!!

Always nice to hear things are working.

Thanks for letting me know peu.

Hi all,
I have the need to slow things down a bit. I'm running a 18F1330 at 32 MHz executing a sense loop for ultrasonics each 32 mS. I have tried to use DT's averaging routine with a 250 reading average, but it still reacts way too fast. I need to dampen it to a 2 or 3 second response so that it doesn't drive the mechanical parts nuts.

It doesn't look like I can just change the AvgCount to a larger variable without messing it up.

Anybody ran into this before?

Thanks for any input while I try and think through this.

After looking closely at my code, I realized that I had tried to tweak DT's code.... as always, likely a mistake....

Went back to the original and it is working more like need. Further testing.

Move along, Nothing to see here.
