In this tutorial, we will learn how to interface I2C LCD with ESP32/ESP8266 and how to display simple text/numbers and custom characters on I2C LCD. . With MicroPython you can interact with devices on an I2C bus using a few Python functions.

You can run the following code to scan the I2C bus for attached devices.

At the physical level it consists of 2 wires: SCL and SDA, the clock and data lines respectively. We will use the scan () function to scan the bus and list out any sensor addresses it finds. 15. They can be initialised when created, or initialised later on. Yes, the client needs to do a recv () regularly, otherwise it can't respond to a scan ().

The I2C LCD will be connected with the ESP board with its 4 pins (GND, VCC, SDA and SCL).
