I am working on creating myself a simple frequency meter (mainly for the challenge of doing so although I may have a few projects that might make use of it later) and I am trying to decide which is the best approach
1) count the number of pulses received during a fixed interval (timer Interrupt & pin change interrupt)
2) record the to to receive X pulses.
Any opinions on which approach would be better, or is it a "You pays your money & Takes your choice" type of decision.
