There we create 4 files: i2c.h, i2c.c, lcd.h and lcd.c. Let’s begin with the I2C module. I2C Module. The modules/i2c.h header file contains some configurations, constants and function prototypes. As a convention we use the “I2C_” prefix in this module.

With your LCD connected, enter i2cdetect -y 1 at the command prompt. This will show you a table of addresses for each I2C device connected to your Pi: The I2C address of my LCD is 21. Take note of this number, we'll need it later. Programming the LCD.

When using I2C, is the pin mapping the mapping from the PCF8574 chip to the LCD parallel interface? I2C is a very broad term and not all i2c librarys handle their mapping.

This library is a modified version of the H. Mario LiquidCrystal_I2C V.2.0 lib.

This is a library for driving LiquidCrystal displays (LCD) by using the I2C bus and an PCF8574 I2C adapter. This library uses the original Wire library for communication and is partially compatible with the LCD API 1.0. It just can be used as a replacement for the LiquidCrystal library.

This post describes how the I2C (Inter-Integrated Circuit, or "Two-Wire") interface works, with particular reference to the Arduino Uno which is based on the ATmega328P microprocessor chip. A lot of the details however will be of more general interest. The Two-Wire interface is extremely useful for connecting multiple devices, as they can all.

Copy the folders under the Library folder to the libraries folder in Arduino (if you cannot find the path in Arduino, open Arduino IDE, click File -> Preferences, and you can see the path in the Browse box, as shown in the following diagram). Compile the program. Step 4: Upload the sketch to the SunFounder Uno board.

When using the ESP32 with the Arduino IDE, use the Wire.h library to communicate with devices using I2C. With this library, you initialize the I2C as follows: ... using a Firebeetle ESP32-E, LiPo battery, and for the first time connected two I2C peripherals (BME sensor and LCD 2 rows), using MicroPython.
