Have you successfully simulated the JHD2X16I2C exclusive model? Share your HEX file configurations in the comments below!
If you landed here, you are likely trying to simulate a 16x2 LCD (Liquid Crystal Display) with an I2C backpack, but you cannot find the exact part in your library. Or perhaps you are looking for a proprietary or hard-to-find model that works flawlessly.
If you are building a professional portfolio schematic or teaching a class, the Exclusive model creates cleaner, more readable schematics. For pure functional testing, the standard method is safer because it doesn't rely on an obscure library file. Part 7: The Future of Proteus and I2C Displays Labcenter Electronics has started integrating native "I2C LCD" models in Proteus 8.9 SP3 and above. As of 2025, many modern versions ship with a component simply named LCD_I2C (16x2).
That’s it. No resistors, no potentiometer. You cannot use the standard LiquidCrystal.h library. You must use the LiquidCrystal_I2C.h library.
