If you CAN afford supersampling that's good, Nyquist would be happy for you:D But one of the topics in the thread was the limited interrupt rate :P And, of course, it all depends on the frequencies you work with: even an analog PLL, a continue process in principle (so more-or-less infinite sample rate), takes more time to lock to lower frequencies... In other words it could be tricky to react to a 1Hz stimulus in a 0.1s timeframe... (in general IIRC it's not possible) ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
