PIC frequency meters/digital scales
There are two groups of variations to the same melody - PIC16F84 based
frequency counters/digital displays:
Both groups are running the same principle described in Microchip Application note AN592 "Frequency Counter Using PIC16C5X" - gating internal PIC prescaler.
Unlike the original idea, projects descibed here are able to measure frequency using 3 byte buffer.
