Hi,
I'm wondering if anyone out there has been able to make an efficient IIR filter for processing raw Accelerometer data. Reason why I'm asking is because I'm trying to get a shape to move around the screen as the user tilts the screen, but the data coming in from the Accelerometer is choppy, so I need an IIR filter to handle that data. There's probably a very simple solution to this but I can seem to figure it out. If anyone's got an IIR filter that I could look over, please don't hesitate to comment!
