I have been assuming that approximately 10kHz was about the maximum sampling rate I could achieve, but it turns out I was very wrong. So far I’ve gotten up to approximately 20kHz and am not seeing any degradation in performance. I’m not sure how high I can (or should) crank this up for optimal system performance, but I’ve already increased the precision from 1 reading every 85 microseconds to 1 every 42 microseconds. Now if only my clock were that accurate.
Where was that noise?
