Esp32 3 How To Use I2c In Esp32 Lcd1602 Espressif Ide Yout The driver i2c.h library will enable the esp32 to communicate with other i2c devices, in our case it is the lcd. the hd44780 is the universal esp idf driver for hd44780 lcd to display texts and numbers. hence, we include the header file “hd44780.h” as well. in your project directory create a component folder and place hd44780 folder there. This tutorial shows how to use the i2c lcd (liquid crystal display) with the esp32 using arduino ide. we’ll show you how to wire the display, install the library and try sample code to write text on the lcd: static text, and scroll long messages. you can also use this guide with the esp8266.
Esp32 3 How To Use I2c In Esp32 Lcd1602 Espressif Ide вђ S For the demonstration purpose, i will use the lcd1602, which is connected via the pcf8574 i2c expander. the esp32 will communicate with the pcf8574, which uses i2c communication, and this in turn will control the lcd. the pcf8574 i2c expander is shown below. as you can see above pcf8574 has 4 input pins gnd, vcc, sda, scl and 16 output pins. Purchase the products shown in this video from :: controllerstech.store. On the i2c module you will find a potentiometer that you can rotate with a small screwdriver. plug in the esp32’s usb connector to power the lcd. you will see the backlight lit up. now as you turn the knob on the potentiometer, you will start to see the first row of rectangles. if that happens, congratulations!. The esp32 supports i2c communication through its two i2c bus interfaces that can serve as i2c master or slave, depending on the user’s configuration. accordingly to the esp32 datasheet, the i2c interfaces of the esp32 supports: standard mode (100 kbit s) fast mode (400 kbit s) up to 5 mhz, yet constrained by sda pull up strength.

Here we use the espressif esp32 to show how it can be used with the i2c 1602 lcd, and also to demonstrate the use of a microcontroller other than an arduino based one with the i2c 1602. we obtain five (5) volts from the vin pin on the esp32 (the pin on the bottom left of the board, if the usb connector is facing down and the board components are facing upward, i.e., they are on top of the board). Step 1: start with the gnd connections. connect the gnd pin of the esp32 module to the gnd of the arduino. choose any gnd pins available on the esp32 for the connection. it is an excellent practice to start with the gnd connections.
