Greetings from Indonesia, I am very happy to be successful always, hopefully the knowledge is a blessing. We are waiting for the next project and program code.

Hello! I have a question. Does this work with the ESP32 2432s028r ?

drive.google.com/drive/folders/1ugiVgwHI1Acst_C2zxr8cmDkIpVEWnIu It wasn't added to the GitHub library 😬😬, you can get it from here.

Fantastic tutorial. However, I ran into a problem where the LCD is blank. I tried testing the I2C pins but I get a message "No I2C device found". Please, how do I resolve this?

Check connection between the Arduino and the i2c board.

My connection is SDA>>D21 SCL>>D23

Try using different wire, sometimes the wires are not good.

Add in setup function Wire.setPins ( 21, 22 ); or whatever. Without this line it will never work.

I already use pin21 for my TFT screen touch function. I'm using SPI library. Can I still use pin21 for I2C? Any conflict for this?

This is late but for anyone If you want to use other pins when using the wire library, you just need to call: `Wire.begin(SDA, SCL);`

You can damage the pins of the ESP32 by sending data with signal levels between 0V and 5V, as shown in this video. The ESP32 can only support up to 3.3V. Use a level shifter between the LCD display and the ESP32 to avoid damaging your board.

Wrong, the power in the LCD is not related to the digital signal, they are separate.

what's the purpose of the antennae, i thought the esp32-wroom-32 had built in wifi
@INOVATRIX26 күн бұрын
It was just an extension I attached myself. The ESP will work as intended with or without it.

Did you already found how to repair this error ?

Use lcd.begin();

In the Arduino > library folder, look for the LiquidCrystal_I2C library and delete it. Then, go to the library manager and search for LiquidCrystal_I2C.h, install Frank de Brabander's version and click install. It will work.
