SendTo: piclist@mitvma.mit.edu Hi PIC gurus! A friend of mine needs accurate frequency measurement in the range cca. 10 Hz - 250 KHz, with at least 3 digits precision (ie. 48.035 Hz). I remember there were threads about frequency counters some time ago. Does someone of you, gurus, have any suggestions, piece of code, pointer, anything related? TIA, max mauricio@arne.si
