This is a basic code which I created so that no one else will need to go through the problems of searching all the forums for the codes.

Connection

LCD= The IIC comunications port (you can modify this sine I use an unofficial UNO replacement.)

LED= GND- GND

VCC- 5V

DIO- 3

CLK- 2

I decided it would be cool since I spend 1 day looking for the library and everything to created this so that you don't have to.

Have fun and please coment on how I could improve.

EXPANDED TECHNICAL DETAILS

Hybrid Information Display Orchestration

This project provides a professional-grade solution for managing both low-resolution LED status grids and high-resolution Alphanumeric LCDs simultaneously.

  • Parallel Display Logic Kernel: The Arduino manages a standard 16x2 LCD via a 4-bit data bus and a 5x7 LED matrix grid via shift registers. The firmware ensures that both displays are updated in perfect synchronization without flickering.
  • Context-Aware Information Mapping: (Features) Use the LED matrix to show a "Graphical Icon" (e.g., a thermometer icon) while the LCD provides the "Detailed Value" (e.g., 24.5°C), creating an intuitive user interface.

Prototyping

  • Verified with Arduino IDE: Optimized for 100% stable performance, featuring the correct initialization sequences for multiple hardware display drivers.
