Re: Converting PULSIN reading to RPM, from PC Fan?
Hi, IoannisOriginally Posted by Ioannis
No, no ... it's not an error : if you divide the pulse train per 2 ( D Flip-flop ...) ... the High or low pulse you get @ output has the exact rotation period ... ( remember how you did that with ol' 74 or 4000 logic chips ...)
rising edge fires the counter ... falling edge stops it.
easy then to care with an IOC interrupt stubb ...

IF there is the word "Problem" in your question ...
