In Proteus simulations, neglecting to include these pull-up resistors is a common mistake. Without proper pull-up resistors (typically 4.7kΩ to 10kΩ on both lines), the SDA and SCL lines will float, and the I2C protocol will fail silently—no errors, just no communication.
Most tutorials cover the basics, but they often miss the specific simulation quirks that cause projects to fail in Proteus.
Copy the downloaded files and paste them into your Proteus library directory:

The standard LiquidCrystal_I2C library assumes a specific wiring pattern for the PCF8574 pins. You must connect the PCF8574 outputs to the LCD inputs exactly as follows, or the display will show garbage:
Since you are looking for an "exclusive" piece regarding the , I have compiled a comprehensive guide that focuses on the specific challenges and "gotchas" unique to this setup.
The 16x2 alphanumeric LCD module is a staple in modern embedded projects, providing a simple, two-wire solution to display data. However, designing hardware around this module can be time-consuming, requiring physical wiring and debugging. Enter the Proteus Design Suite , which offers an exclusive, high-fidelity simulation model for the JHD2X16I2C .
To successfully simulate this "exclusive" piece, standard libraries may fail. You often need specialized drivers: Library Requirement : The standard LiquidCrystal library usually does not work. Use the DFRobot_RGB_LCD1602 DF Robot LCD Point H libraries for correct configuration. Installation Download the files for the JHD module. Place these files in the folder of your Labcenter Electronics directory (usually in Program Files).

: Connect the SDA pin of the JHD2X16I2C module to Analog Pin A4 on the Arduino Uno.
If the I2C debugger logs an address frame but receives a NACK (No Acknowledge), change your code initialization address from 0x27 to 0x3F or vice versa.
