Re: Joysticks typical polling freq.

I can’t add much more than a hat has all eddy been stated but I will put in this note for paddles, if someone later searches for this.   The paddles use 512 cycles to take a reading so there will be absolutely no benefit to reading more than once every 512 cycles.  I agree that’s far too often but just noting the paddle hardware does have an upper bound.
