Hello trannd 55, welcome at DaniWeb.
This is an example of how to use a serial port. Once you can read data from it, you could write any kind of filter method you like, I guess.

Oh, thanks ddanbe!,
i have finished build project about: plot real time data from serial port
but i want to filter signal(high-pass, low-pass, notch filter), which i'm plotting.
Anyone can help me? pls!

Is this not applying some formulas on the data from the serial port?
