: Ensure your code library matches the pin mapping of the PCF8574 to the LCD (RS, RW, and EN pins).

: Search the Proteus library for "PCF8574" and "LM016L" (the standard 16x2 LCD) or a pre-assembled "LCD I2C" module if your library has it. jhd-2x16-i2c proteus

Ensure the pull-up resistors on SDA/SCL are tied to an active digital VCC terminal. : : Ensure your code library matches the pin

: I2C communication can sometimes slow down Proteus. Ensure your "Clock Frequency" for the microcontroller is set accurately.

Connect the pin of your microcontroller to the SCL (Pin 14) of the PCF8574.

The JHD-2X16-I2C module consists of two distinct parts merged into one package:
