To mimic the internal wiring of the JHD-2X16-I2C module, connect the pins exactly as follows: PCF8574 Pin LM016L (16x2 LCD) Pin RS (Pin 4) Register Select P1 RW (Pin 5) Read/Write P2 E (Pin 6) P3 Backlight (Optional) Controls physical backlight LED P4 D4 (Pin 11) Data Bit 4 P5 D5 (Pin 12) Data Bit 5 P6 D6 (Pin 13) Data Bit 6 P7 D7 (Pin 14) Data Bit 7

Ensure that you have connected pull-up resistors to both the SCL and SDA lines. Proteus digital simulation engines require explicit logic states; floating lines generate simulation artifacts or errors. jhd-2x16-i2c proteus

To interface the JHD-2X16-I2C with a microcontroller like an Arduino Uno in Proteus, follow these pin mappings: : Connect to 5V power. GND/VSS : Connect to the common ground.

The is a popular 16x2 character Liquid Crystal Display (LCD) module widely used in embedded systems for displaying text and numeric data. While the standard module uses a parallel interface requiring 6-10 I/O pins, the JHD-2X16-I2C variant integrates a PCF8574 I2C I/O expander, reducing the pin requirement to just two pins—SDA (Serial Data) and SCL (Serial Clock)—plus power. void setup() lcd

void main(void) I2C_init(100000); // Example I2C write sequence SEN = 1; // Send Start condition while(SSP1STATbits.BF); SSP1BUF = 0x7C << 1; // Send slave address (0x7C) + write while(SSP1CON2bits.ACKSTAT); SSP1BUF = 0x00; // Send control byte while(SSP1CON2bits.ACKSTAT); PEN = 1; // Send Stop condition GND/VSS : Connect to the common ground

The JHD-2X16-I2C module has only 4 pins:

In the , there is no direct component labeled strictly "JHD-2x16-I2C". Instead, simulation is achieved by combining a standard LM016L (or similar HD44780-compatible 16x2 LCD) with a PCF8574 I/O expander. This paper provides a comprehensive guide to simulating this setup.
