An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...

In previous tutorial, OLED is interfaced with ESP32 using SPI communication which uses 5 pins. In this tutorial, we interface 16x2 LCD with ESP32, using only 2 pins, with the help of I2C communication ...

When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than s… ...

This project simplifies the use of KS0108-based monochrome graphic LCD modules. These displays have an 8-bit parallel interface and control signals that would need at least 14 port pins of your host ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
