• In IoT, LCD is rarely required, but some times its useful
to monitor errors and connection related issues. In this
lesson we are interfacing I2C LCD with ESP8266.

• Embedded Systems should be connected with each other to transfer data
between them. Because all operations can’t be performed on a single
system.
• For example, Arduino has 6 analog pins but NodeMCU has only one
analog pin. So two are more microcontrollers or microprocessors can be
combined to form a required embedded system.
• The connection can be established through any of the following
protocols.
SPI
I2C
UART

4. I2C Communication Protocol
Eng.
Elaf
A.Saeed
• The I2C communication bus is very popular and broadly used by
many electronic devices because it can be easily implemented in
many electronic designs which require communication between a
master and multiple slave devices or even multiple master devices.
• The easy implementations comes with the fact that only two wires
are required for communication between up to almost 128 (112)
devices when using 7 bits addressing and up to almost 1024
(1008) devices when using 10 bits addressing.

Step 1: Installing I2C LCD Library for ESP8266 and ESP32
• This library is tested for different types of LCD displays like
16×2, 16×4, 20×2, 20×4 with both ESP32 and ESP8266, it also
works with other ESP modules.
Step 2: Install it in Arduino IDE
• Click on Sketch >> Include Library >> Add .ZIP Library
