Which you are planning to simulate (Arduino, PIC, or 8051)? The exact version of Proteus you currently have installed?
Double-click the microcontroller in Proteus and load the .hex file. Press to start the simulation. 5. Troubleshooting Common Issues
If you want, I can: provide a ready-to-use Arduino .ino sketch, a Proteus parts list with exact component names, or search for a free PCF8574 Proteus model and give download instructions. Which would you like? jhd2x16i2c proteus free
Ensure the .LIB and .IDX files were placed in the correct LIBRARY folder and that you restarted Proteus.
The JHD2X16I2C is a popular 16x2 character LCD module equipped with an integrated I2C adapter (typically based on the PCF8574 chip). Simulating this display in Proteus allows you to test your microcontrollers (like Arduino, PIC, or 8051) without buying physical hardware. Which you are planning to simulate (Arduino, PIC, or 8051)

Proteus does not always include the specific "JHD2X16I2C" model in its default, out-of-the-box library. However, you can achieve a 100% accurate simulation for free using native components or community-contributed libraries. Press to start the simulation
Place a on the SCL line and connect it to VCC (Pull-up).
