Depends a bit what kind of filter you want. Butterworth or moving average filters are quite common because they are the simplest.
I usually e.g. precompute the butterworth filter coefficients using butter, and then apply them to the incoming stream manually.

Just google it, you will find a million results.
It's not too technical and skips a lot of theory, but great as introductory literature for applications.
