@jamrom2 said in Why does my 8bitdo and PS3 controllers randomly move?:

so if a ghost input is +.02 volts... and an actual press gives + 1.2 volts... you would set the null to ignore anything under +1.0 volts. Effectively ignoring the ghost input.

It doesn't work like that. There is no method to know how much 'volts' trigger the input, in order to ignore it or not.
