FPGA-based digital frequency meter: 1. Measurement 1Hz ~ 1GHz square wave frequency, accuracy decile.
(2) automatically adjusts the stalls, divided into 1Hz ~ 999.9Hz, 1KHz ~ 999.9KHz, 1MHz ~ 999.9MHz three stalls.
3 for 16-bit divider, the frequency calculations, and ASIIC code output measured data.
