Unlocking the Power of jhd2x16i2c in Proteus: A Complete Guide to Free Simulation

  • Add “Arduino UNO” (or the MCU you prefer).
  • Add “LCD 16x2” (HD44780) component.
  • If PCF8574 is available in your Proteus version/library, add it; if not, you’ll emulate the I²C adapter by wiring the LCD pins via virtual bus or use a user-made PCF8574 model from community libraries.
  • Compile your sketch in Arduino IDE using LiquidCrystal_I2C or similar.
  • Export the compiled .hex and attach it to the Arduino component in Proteus (or use Proteus’s Arduino simulation support to load the .ino).

Pro tip

💡 : In Proteus, ensure the I2C pull-up resistors (4.7kΩ) are connected from SDA/SCL to +5V, or the simulation may freeze.
