PIC frequency meters/digital scales

There are two groups of variations to the same melody - PIC16F84 based frequency counters/digital displays:

LED display variants
LCD display variants

Short summary of all projects. HEX code of all projects!!!!
LED counter PCB for SMD!

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.
