Double-click the JHD-2X16-I2C component and examine its property sheet. Confirm that DVCADDR=$7C is set. If your code uses a different address (like 0x27 or 0x3F), change the property to match. This is one of the most important steps for a successful simulation.
: In Proteus simulations, the default address for this type of module is typically jhd2x16i2c proteus exclusive
Here is an exclusive guide to setting up the JHD-2X16-I2C simulation accurately. 1. The Right Library is Everything Most users fail because they use the default LiquidCrystal_I2C library. For the JHD2X16I2C, you must use the DFRobot_RGB_LCD1602 library or the DF Robot LCD Point H jhd2x16i2c proteus exclusive
