Frequency Counter Frequency Counter

100Mhz frequency counter and timer - Hardware, AVR, ATmega, ASM, Electronics, HF

In counter mode it provides 1Hz resolution up to 100Mhz. In timer mode maximum resolution is 0.0000001 Hz up to 1Hz. Resolution is reduced by one digit for each additional decade. Multiple frequency updates per second by employing a sliding window for calculation.
