Welcome to the lcd-i2c-library repository! This library provides an interface to control an HD44780-based LCD via an I2C converter using the PCF8574 module. If you are working on an Arduino or AVR ...

After uploading the sketch, open the Arduino Serial Monitor (Tools > Serial Monitor). The sketch will automatically detect the I2C address of the connected LCD module and initialize it. You should see ...

This paper presents the design of an Intellectual Property (IP) that converts a serial output signal into a parallel output signal for a liquid crystal display (LCD). The IP is intended for ...

However, a serial interface is slower than a parallel interface, and it requires a special protocol and hardware to encode and decode the data. Some common serial protocols are SPI, I2C, and UART.

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

The Waveshare 1.69-inch IPS touch LCD is a 1.69-inch rounded display with 240×280 resolution and a 262K color range. The display driver (ST7789V2) and touch controller (CST816T) are integrated ...
