7 segment 4 digits (and extended to generic 1 to 8 digits) LED display easy to use and powerful library for modules based on two 74HC595 (or similar) shift registers chips
Originally developed for the cheap and popular '4-bit Led Digital Tube Module', extended for the various models from 1 to 8 digits, (and for all the custom made displays as: GIANTS COUNTERS, TIMERS, PRICING DISPLAYS, etc.) based on two 74HC595 (or similar) shift registers, the main focus was set on: ease of use, flexibility and basic prevention of 'misrepresentation' errors.
