Hi,

I'm experimenting with an Arduino board (talking to PD via Pduino). It's sending data in quite large steps (I guess this is due to analogue value -> digital sampling rate which I'm increased to maximum).

Is there a way to smooth value changes? So that if it jumps in four steps: 100 - 121 - 210 - 300, the values would be smoothed to 100, 101, 102, 103, 104 ... 298, 299, 300? Is that possible? I tried using "average", but it seems to introduce a LOT of latency. I understand that there will be a slight latency, but have you got any tips how to implement this for a realtime controller?

Thanks!

use [line], possibly in combination with [int] if you only want rounded values.

Thanks! [line] did the trick!
Good stuff!

I have the opposite problem using the accelerometer data from my iphone. everything is jittery because of how many data points are registering. For example .012,.013,.011,.015 all happen in half a second and I'm not moving the controller when these slight changes are being registered.

How can I thin this data so that only a change from .012 to .095 would be output?

Thanks, this worked for me in a patch to tame the jitter in a wiimote input. tweaking the > value did the trick.
