: Connect the SCL pin of the JHD2X16I2C module to Analog Pin A5 on the Arduino Uno.
: The simulation throws I2C errors like "No ACK" (NACK) or the bus hangs. Cause : Missing or incorrect pull-up resistors, or the master clock frequency is set too high for the simulation model to process. Solution : Ensure both 4.7kΩ pull-up resistors are present. Additionally, check your MCU's I2C initialization code. The CLOCK=100kHz property of the JHD2x16I2C is a fixed property of its model. While real modules can often go up to 400kHz (Fast Mode), for reliable simulation, it is best practice to configure your MCU’s I2C peripheral to generate a 100kHz clock to match the model exactly. jhd2x16i2c proteus exclusive

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).
Proteus does not always include a component explicitly labeled "JHD2X16I2C" in its default library. You can perfectly emulate it using standard I2C alphanumeric display blocks. 1. Picking the Components
