Frequency Counter Using Interrupts at Alfred Palmer blog

Frequency Counter Using Interrupts. I have been trying to count pulses from a 12,500 hz square wave to trigger an output. The right way to count frequencies from a few hertz up to 6 mhz using an arduino board. Add a display and build a low cost frequency meter. I've found it's handy to debounce your switches externally so you dont need a delay or additional complex code. Configure hardware timers and use interrupts. Float f = (float)1 / counter.period; A more complex method is reciprocal counting. A simple frequency counter measures frequency by counting the number of edges of an input signal over a defined period of time (t). Interrupt triggered by the input signal. For example, in between 2 pulses. I have been trying to create a system that will count the number of pulses read on a pin in between pulses of another signal using interrupts. Counting multiple frequencies with polling and interrupts. Here's the code i have so far. The frequency measurement is done by assigning interrupt to a io and then increasing a counter every time the irq.
