If your Proteus version lacks the specific I2C LCD component, you may need to add it manually:
Since the JHD-2X16-I2C might not be in the default Proteus library, you can build it using a standard LCD and an I2C adapter. Arduino Forum Pick Components: Search for and place the following in your schematic: Arduino Uno/Nano (or your preferred microcontroller). (The I2C I/O expander commonly used for these displays). (Standard 16x2 Alpha-Numeric LCD). Wiring the PCF8574 to LCD: P4, P5, P6 of the PCF8574 to the RS, RW, and E pins of the LCD. to the LCD's data pins (depending on your library's configuration). Wiring to Arduino: Connect the PCF8574 to Arduino to Arduino Tie the address pins A0, A1, A2 to Ground (this sets the I2C address to in simulation). Arduino Forum 2. Install the Required Libraries LiquidCrystal_I2C jhd2x16i2c proteus free
Since the standard LCD library in Proteus is for parallel communication, you need a specific approach to simulate an I2C LCD. Here is the complete guide on how to get this feature working in Proteus for free. If your Proteus version lacks the specific I2C
If you need a truly and saveable environment: (Standard 16x2 Alpha-Numeric LCD)
The true "free" solution involves:
Place the LCD: Place the JHD2X16I2C module on the schematic. Wire the I2C Bus:
