I'm working on a POV project, and I'm using a digital HES w/ a magnet. In the code I have it set as an interrupt on the falling edge, which triggers on initial contact of the magnet. I'm running into the issue of the image jittering around a little big. It seems to within a small window. Sometimes it'll stay put for a bit, then it'll start to drift, then jitter a little. Rinse repeat.
I did a print out of HES output as it crosses the magnet and it seems to have a decent sized window. I know the HES I'm using is high sensitivity (a possible issue I know), and it probably doesn't help that it's a digital output rather than an analog. My 2nd revision is going to be an analog so then I could pick the peak signal as the trigger for the "home" position.
Any ideas or recommendations (Besides buying an analog)? The only thing I can think of at this point is to A) use a smaller magnet (would have to order one) or B) back the magnet away to narrow the field that the HES would pick up on.
