// Set the LCD address to 0x27 for a 16 chars and 2 line displayLiquidCrystal_I2C lcd(0x27, 16, 2);

Use the "I2C Debugger" tool found in the Virtual Instruments terminal.

The standard LM016L or JHD162A models in Proteus use 16 pins (Parallel). They do not natively support the 2-pin I2C interface (SDA, SCL). jhd2x16i2c proteus free

A: Almost always, this is an I²C address mismatch. Verify that the address in your code (e.g., 0x27 ) matches the model's default ( 0x7C ).

How to Use JHD2X16I2C LCD in Proteus: Free Library and Simulation Tutorial

: Available via the Arduino IDE Library Manager ( Tools > Manage Libraries ). A: Almost always, this is an I²C address mismatch

Close and reopen Proteus for the changes to take effect.

: While physical modules often use address 0x27 or 0x3F , Proteus simulations generally require address 0x20 when all address pins (A0, A1, A2) of the PCF8574 are grounded.
