Hi all, I understand that the analogRead takes about 100 usec. I've been able to successfully use Jmknapp's method to get the reads much faster (closer to 20 usec). Thanks for that!
But I'm doing some fine tweaking on the program and was wondering if anybody knew off-hand whether the sample actually takes place near the beginning of the analogRead function, or closer to the end, or somewhere in the middle. I'm recording the time of the sample and wanted to know if I should record the time just before, or just after the analogRead statement to get the time closer to the actual moment the signal was sampled.
